See GEN 1.6 for the availability of Title 14 of the U.S. Code of Federal Regulations Parts 1-199.

ANNEX 1 - PERSONNEL LICENSING

Chapter 1

Definitions and General Rules Concerning Licences

Remote co-pilot

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

Remote flight crew member

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

Remote pilot

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

Remote pilot station (RPS)

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

Remotely piloted aircraft (RPA)

The United States has not formally established a definition for the term “RPA.” Instead, the FAA defines Unmanned Aircraft in 14 CFR 1.1. Unmanned aircraft means an aircraft operated without the possibility of direct human intervention from within or on the aircraft. The registration requirements established in 14 CFR parts 47 and 48 therefore apply to Unmanned Aircraft.

Remotely piloted aircraft system (RPAS) (Applicable until 25-Nov-2026)

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

1.2.5.2

Balloon pilots exercising commercial pilot privileges are required to hold a second class medical certificate. Private balloon and glider pilots are not required to hold medical certificates but are prohibited from operating during periods of medical deficiency.

The FAA does not provide operational rules specific to RPAS operations allowed internationally. Medical requirements are pending development of associated operational rules.

Regarding certificates issued to Mechanics and Repairmen under 14 CFR part 65, Medical Assessment is NOT applicable.

The FAA does not issue a multi-crew license.

1.2.5.2.2

U.S. commercial pilots engaging in single-crew commercial air transport operations carrying passengers have a 12-month validity on their medical assessments regardless of age.

1.2.5.2.3

U.S. commercial pilots have a 1-year validity on their medical assessments regardless of age.

1.2.5.2.4

Balloon pilots, at the private pilot certificate level, as well as glider pilots are not required to hold medical certificates but are prohibited from operating during periods of medical deficiency. Certain holders of U.S. private pilot licenses (operating domestically) are not required to hold an FAA medical certificate but must meet U.S. (“Basic Med") regulations effective May 1, 2017. “Basic Med" requires a medical education course every 24 months and medical examination every 48 months.

For operations of small Unmanned Aircraft systems under 14 CFR part 107, while medical certification is not a requirement, a participant for the operation must meet a performance-based requirement prohibiting participation in the operation if he or she knows or has reason to know that he or she has a physical or mental condition that would interfere with the safe operation of the small unmanned aircraft system.

More complex UAS operations enabled under traditional aviation rules must meet applicable medical requirements unless otherwise exempted.

1.2.5.2.5

U.S. private pilots required to hold an FAA 3rd class certificate who have passed their 40th birthday have a 24‐month validity on their medical assessments. Free balloon and glider pilots are not required to hold medical certificates but are prohibited from operating during periods of medical deficiency.

1.2.5.2.6

The United States does not defer medical examinations. However, the United States has not established the medical assessment appropriate to the license for a “remote flight crew member.” Remote Piloted Aircraft Systems (RPAS)-specific operational rules for international operations are not currently implemented in 14 CFR regulations.

1.2.9.6

During the student pilot application process, a practical test, flight review, instrument proficiency check (IPC), or pilot- in-command (PIC) proficiency check, the individual conducting testing, training, a review, or any required regulatory check should evaluate if the applicant for an FAA certificate or holder of an FAA certificate demonstrates the FAA Aviation English Language Standard (AELS).

ANNEX 2 - RULES OF THE AIR

Chapter 1

Definitions

Advisory Airspace

Advisory service is provided in terminal radar areas and the outer areas associated with Class C and Class E airspace areas.

Aerodrome Traffic Zone

There are no more Control Zones (Airport Traffic Zones) or Airport Traffic Areas (ATA). In the 7110.65, PCG, Controlled Airspace covers the defined dimensions of airspace. Class D was formerly the ATA (normally a 5NM radius around the airport). The old Control Zones were extensions of the ATA to encompass (ILS) Approach Paths.

Airborne Collision Avoidance System (ACAS)

The U.S. uses “traffic alert collision avoidance system (TCAS)." TCAS is an airborne collision avoidance system based on radar beacon signals and operates independent of ground−based equipment. TCAS−I generates traffic advisories only. TCAS−II generates traffic advisories and resolution (collision avoidance) advisories in the vertical plane.

Air-taxiing

The U.S. uses “air taxi” below 100 feet above ground level (AGL) and “hover taxi” for this maneuver actual height may vary, and some helicopters may require hover taxi above 25 feet AGL to reduce ground effect turbulence or provide clearance for cargo slingloads.

Air traffic services unit

References to this are embedded in AIP, ENR 7.1-3.1.1, ENR 7.1-3.1.5, and ENR 7.1-5.2 Note without an accompanying definition.

Alternate Aerodrome

1) The U.S. definition does not include the information that defines this concept. Additionally, the U.S. uses the term “airport” in place of “aerodrome.”

2) The definition annotated as [ICAO] is not congruent with the Annex 2 Amdt 47 text.

Altitude

The U.S. defines “altitude” using the imperial measurement of feet.

Approach Control Service

The U.S. not only includes arriving and departing controlled flights but also includes en route controlled flights. Additionally, as opposed to Annex 2 Amdt 47, the U.S. specifies the control facility that provides the service.

Approach Control Unit

The U.S. defines “Approach Control Facility.”

Appropriate ATS Authority

The U.S. does not define “Appropriate ATS Authority.” The P/CG does contain a definition annotated as [ICAO] that adds “In the United States, the “appropriate ATS authority” is the Program Director for Air Traffic Planning and Procedures, ATP-1.”

Apron

The U.S. adds reference to seaplane operations to the definition.

Area control centre

The U.S. equivalent facility for an Area Control Centre (ACC) is an Air Route Traffic Control Center (ARTCC).

Area control service

The U.S. does not use the term “area control service” to indicate controlled flight in controlled areas.

Automatic Dependent Surveillance-Broadcast (ADS-B)

1) The U.S. separately defines ADS-B, ADS-B Out, and ADS-B In.

2) The U.S. defines ADS-B as surveillance whereas Annex 2 Amdt 47 does not.

3) While the Annex 2 Amdt 47 definition specifies aircraft, aerodrome vehicles, and other objects, the U.S. specifies aircraft or vehicle, and makes no mention of other objects.

Ceiling

The U.S. specifies what the “lowest layer” consists of, which can include obscurations other than clouds.
The U.S. imposes no altitude limit in its definition.

Changeover point

The U.S. defines the makeup of the point as “…a point along the route or airway segment between two adjacent navigation facilities or waypoints where changeover in navigation guidance should occur.”

Command and Control (C2) Link

Remote Piloted Aircraft Systems (RPAS)-specific operational rules allowing for international operations are not currently addressed/implemented in 14 CFR regulations.

Control Area

The term is used throughout U.S. documentation without an actual FAA definition. The Annex 2 definition is included and annotated [ICAO].

Controlled aerodrome

The U.S. does not define “Controlled Aerodrome.” The terms Control Tower, Approach Control, etc. are used in lieu.

Controlled Flight

The U.S. does not define “Controlled Flight.”

Controller-pilot data link communications (CPDLC)

The U.S. specifies digital communications, textual messages, and radio relay stations.

Control Zone

The U.S. renamed “control zone” as “surface based controlled airspace.”

Danger Area

The term “danger area” is not used within the U.S. or any of its possessions or territories.

Data Link Communications

While the U.S. does not define “Data Link Communications,” it does define “CPDLC” and “ADS-C.”

Detect and Avoid

The U.S. does not define “Detect and Avoid.”

Estimated Time of Arrival

The U.S. limits the applicability to airport landing operations.

Expected Approach Time

The U.S. does not define “Expected Approach Time.”

Flight information centre

The U.S. does not operate flight information centers (FICs). In the U.S., the services provided by FICs are performed by air traffic control (ATC) facilities, flight service stations (FSSs), and rescue coordination centers (RCCs).

Flight Level

The U.S. uses the measurement of a level of constant atmospheric pressure related to a reference datum of 29.92 inches of mercury instead of 1 013.2 hectopascals (hPa).

Heading

The U.S. does not define “Heading.”

Height

The U.S defines Height as the height above ground level (or AGL) expressed in meters or feet.

Instrument Approach Operations

The U.S. does not define “Instrument approach operations.”

Instrument Approach Procedures

The U.S. does not include a reference to “holding or en route obstacle clearance criteria” application in its definition.

Level

The U.S. uses “altitude” or “flight level” rather than “level” and “cruising altitude” rather than “cruising level.'' The term “level” is not used to mean “height,” “altitude,” or “flight level.”

Manoeuvring Area

In the U.S., the term “movement area” means “the runways, taxiways, and other areas of an airport/heliport which are utilized for taxiing, hover taxiing, air-taxiing, take-off and landing of aircraft, exclusive of loading ramps and parking areas. At those airport/heliports with a tower, specific approval for entry onto the movement area must be obtained from ATC.”

The U.S. does not use an all-inclusive term to denote the movement area plus loading ramps and parking areas of an airport, nor does the U.S. use the term “maneuvering area'' in any related context.

Movement area

In the U.S., the term “movement area” means “the runways, taxiways, and other areas of an airport/heliport which are utilized for taxiing, hover taxiing, air-taxiing, take-off and landing of aircraft, exclusive of loading ramps and parking areas. At those airport/heliports with a tower, specific approval for entry onto the movement area must be obtained from ATC.”

The U.S. does not use an all-inclusive term to denote the movement area plus loading ramps and parking areas of an airport, nor does the U.S. use the term “maneuvering area'' in any related context.

Radiotelephony

The U.S. Does not define “Radiotelephony.”

Remote pilot station

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

Remotely Piloted Aircraft (RPA)

The United States has not formally established a definition for the term “RPA.” Instead, the FAA defines Unmanned Aircraft in 14 CFR § 1.1 as an aircraft operated without the possibility of direct human intervention from within or on the aircraft. The registration requirements established in 14 CFR parts 47 and 48 therefore apply to Unmanned Aircraft.

Remotely Piloted Aircraft System (RPAS)

Remote Piloted Aircraft Systems (RPAS)-specific operational for international operations are not currently implemented in 14 CFR regulations.

RPA observer

Rather than “RPA Observer” the FAA uses the term “Visual Observer.”

Repetitive flight plan (RPL)

The U.S. uses the term “stored flight plan” for domestic operations.

Signal Area

The U.S. does not define “Signal Area.”

Special VFR Flight

The U.S. uses the definition “Special VFR Operations” in place of “Special VFR Flight.”

Taxiway

The U.S. does not define “Taxiway.” It does define “Rapid Exit Taxiway” under “High Speed Taxiway” but not the other two definitions embedded in Annex 2 Am47.

Traffic Information

The U.S. uses the term Traffic Advisory.

Transition altitude

In U.S. domestic airspace, “transition altitude,” “layer” and “level” are not used; however, in the U.S., flight levels begin at FL 180 where the reference datum of 29.92 inches of mercury is used as the constant atmospheric pressure. Below FL 180, altitudes are based on barometric pressure readings. QNH and QFE altimeter settings are not provided in domestic U.S. airspace.

Unmanned Free Balloon

The U.S. does not define “Unmanned Free Balloon.” The U.S. definition of Unmanned Aircraft (UA) states Unmanned Free Balloon is not a UA.

Visual line-of-sight (VLOS) operation

The United States defines “Visual line-of-sight aircraft operation” as follows: “With vision that is unaided by any device other than corrective lenses, the remote pilot in command, the visual observer (if one is used), and the person manipulating the flight control of the small unmanned aircraft system must be able to see the unmanned aircraft throughout the entire flight in order to:

(1) Know the unmanned aircraft's location;

(2) Determine the unmanned aircraft's attitude, altitude, and direction of flight;

(3) Observe the airspace for other air traffic or hazards; and

(4) Determine that the unmanned aircraft does not endanger the life or property of another.

(b) Throughout the entire flight of the small unmanned aircraft, the ability described in paragraph (a) of this section must be exercised by either:

(1) The remote pilot in command and the person manipulating the flight controls of the small unmanned aircraft system; or

(2) A visual observer."

Chapter 3

General Rules

3.1.8

In addition, aircraft shall not be flown in formation flight when passengers are carried for hire.

3.1.9

The United States has not specified safety requirements applicable to international RPAS operations.

3.1.10

14 CFR part 101 prescribes rules governing the operation in the United States, of any unmanned free balloon that—
(i) Carries a payload package that weighs more than four pounds and has a weight/size ratio of more than three ounces per square inch on any surface of the package, determined by dividing the total weight in ounces of the payload package by the area in square inches of its smallest surface;
(ii) Carries a payload package that weighs more than six pounds;
(iii) Carries a payload, of two or more packages, that weighs more than 12 pounds; or
(iv) Uses a rope or other device for suspension of the payload that requires an impact force of more than 50 pounds to separate the suspended payload from the balloon.

3.2.2

When weather conditions permit, regardless of whether an operation is conducted under instrument flight rules or visual flight rules, vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft. When a rule of this section gives another aircraft the right-of-way, the pilot shall give way to that aircraft and may not pass over, under, or ahead of it unless well clear.

3.2.3.2 d)

The U.S. national regulations do not require aircraft on the movement area of an airport, whose engines are running, to display lights which indicate that fact from sunset to sunrise.

3.2.5

Unless otherwise authorized or required by ATC, no person may operate an aircraft within a Class B, C, or D surface area except for the purpose of landing at, or taking off from, an airport within that area.

In addition, in the case of a helicopter approaching to land, avoid the flow of fixed-wing aircraft.

In addition, no person may, within a Class B, C, or D surface area operate an aircraft to, from, or on an airport having a control tower operated by the U.S. unless two-way radio communications are maintained between that aircraft and the control tower.

3.3.1.2

In the U.S., ATC flight plans are not required for VFR flight in Class C, D, or E airspace.

3.3.1.2 e)

Requirements pertaining to filing flight plans for flights operating across U.S. borders and for identification purposes are described in 14 CFR Part 9l (Section 91.84) and Part 99.

3.6.2.4

When meteorological conditions fall below the minimum specified for en route VFR flights, the pilot of the aircraft shall not continue his/her flight in such conditions, except in emergency, beyond the extent necessary to return to his/her departure point or to the nearest suitable landing point.

3.6.5.2 (Communication Failure)

Two-way Radio Communications Failure
a. It is virtually impossible to provide regulations and procedures applicable to all possible situations associated with two-way radio communications failure. During two-way radio communications failure, when confronted by a situation not covered in the regulation, pilots are expected to exercise good judgment in whatever action they elect to take. Should the situation so dictate they should not be reluctant to use the emergency action contained in 14 CFR Section 91.3(b)
b. Whether two-way communications failure constitutes an emergency depends on the circumstances, and in any event, it is a determination made by the pilot. 14 CFR Section 91.3(b) authorizes a pilot to deviate from any rule in Subparts A and B to the extent required to meet an emergency.
c. In the event of two-way radio communications failure, ATC service will be provided on the basis that the pilot is operating in accordance with 14 CFR Section 91.185. A pilot experiencing two-way communications failure should (unless emergency authority is exercised) comply with 14 CFR Section 91.185 quoted below
1. General. Unless otherwise authorized by ATC, each pilot who has two-way radio communications failure when operating under IFR shall comply with the rules of this section.

3.6.5.2.2

In the event of two-way communications failure in the U.S., ATC service is predicated on pilot compliance with the provisions of 14 CFR Part 91 (Section 91.185). If the failure occurs in IMC, or if VFR cannot be complied with, each pilot is to continue the flight according to the following:
Route
a) By the route assigned in the last ATC clearance received;
b) If being radar vectored, by the direct route from the point of failure to the fix, route, or airway specified in the vector clearance;
c) In the absence of an assigned route, by the route that ATC has advised may be expected in a further clearance; or
d) In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance, by the route filed in the flight plan.

Altitude - At the HIGHEST of the following altitudes or flight levels FOR THE ROUTE SEGMENT BEING FLOWN:
a) The altitude or flight level assigned in the last ATC clearance received;
b) The minimum altitude/flight level as prescribed for IFR operations; or
c) The altitude or flight level ATC has advised may be expected in a further clearance.

IFR conditions - If the failure occurs in IFR conditions, or if subparagraph 2 above cannot be complied with, each pilot shall continue the flight according to the following:
(a) Route.
(1) By the route assigned in the last ATC clearance received;
(2) If being radar vectored, by the direct route from the point of radio failure to the fix, route, or airway specified in the vector clearance;
(3) In the absence of an assigned route, by the route that ATC has advised may be expected in a further clearance; or
(4) In the absence of an assigned route of a route that ATC has advised may be expected in a further clearance by the route filed in the flight plan.
(b) Altitude. At the HIGHEST of the following altitudes or flight levels FOR THE ROUTE SEGMENT BEING FLOWN:
(1) The altitude or flight level assigned in the last ATC clearance received;
(2) The minimum altitude (converted, if appropriate) to minimum flight level as prescribed in 14 CFR Section 91.121(c) for IFR operations; or
(3) The altitude or flight level ATC has advised may be expected in a further clearance.

3.6.5.2.2 a)

Annex 2 references maintaining last assigned speed, level, or minimum flight altitude for a specified amount of time depending on radar coverage. 91.185 does not require last assigned speeds and altitudes be maintained for specified amounts of time.

3.9

There is no Class F airspace in the U.S. Basic VFR weather minimums are listed in the table below.

Except as otherwise authorized by the appropriate air traffic control unit for special VFR flights within Class B, C, D, or E surface areas, no person may operate an aircraft under VFR when the flight visibility is less, or at a distance from clouds that is less than that prescribed for the corresponding altitude and class of airspace in the table below.

Class G Airspace: Notwithstanding the provisions of paragraph a) of this section, the following operations may be conducted in Class G airspace below 1,200 feet above the surface:
1) Helicopter. A helicopter may be operated clear of clouds if operated at a speed that allows the pilot adequate opportunity to see any air traffic or obstruction in time to avoid collision.
2) Airplane. When the visibility is less than 3 statute miles but not less than 1 statute mile during night hours, an airplane may be operated clear of clouds if operated in an airport traffic pattern within one-half mile of the runway.

Except as provided in 4.2, no person may operate an aircraft under VFR within the lateral boundaries of the surface areas of Class B, Class C, Class D, or Class E airspace designated for an airport when the ceiling is less than 1,000 feet.

Except as provided in 4.2, no person may take-off or land an aircraft, or enter the traffic pattern area of an airport under VFR, within the lateral boundaries of the surface area of Class B, Class C, Class D, or Class E airspace designed for an airport:
1) unless ground visibility at that airport is at least 3 statute miles; or
2) if ground visibility is not reported at that airport, unless flight visibility during landing or takeoff, or while operating in the traffic pattern is at least 3 statute miles

Chapter 4

Visual Flight Rules

4.2

In the U.S., no person may operate an aircraft beneath the ceiling under VFR within the lateral boundaries of controlled airspace designated to the surface for an airport when the ceiling is less than 1,000 feet. No person may take-off or land an aircraft (other than a helicopter) under special VFR (SVFR) unless ground visibility is at least 1 statute mile or if ground visibility is not reported, unless flight visibility is at least 1 statute mile.

The U.S. restricts the ceiling to 1,000 ft. and ground visibility of 3 miles and greater.

4.3

The U.S. does not prohibit VFR flight between sunset and sunrise.

4.4

In the U.S., VFR flight is not permitted within Class A airspace designated in 14 CFR Part 71 unless otherwise authorized by ATC.

In the U.S., an ATC clearance is needed for VFR flight only in Class B airspace area.

The U.S. limits VFR flights up to FL 180.

4.5

The U.S. limits VFR flights up to FL 180.

4.7

In addition, grid tracks are not used to determine cruising altitudes in polar areas. True tracks are used to determine cruising levels above FL 230 in the area north of Alaska bounded by the true North Pole to 72°00′00"N, 141°00′00"W; to 72°00′00"N, 158°00′00"W; to 68°00′00"N, 168°58′23"W; to point of beginning.

4.8

In U.S. Class C and D airspace/areas, an ATC clearance is not required for VFR flights.

Chapter 5

Instrument Flight Rules

5.1.2

In the U.S., minimum altitudes for IFR flights are 2,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown in mountainous terrain and 1,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown in non-mountainous terrain.

5.2.2

See difference under paragraph 4.7.

5.3.1

See difference under paragraph 4.7.

Further differences which exist by virtue of the fact that the Annex contains no comparable standards for the U.S. national regulations.

1) The regulations covering the selection and use of alternate airports in respect to ceiling and visibility minima, require that:

Unless otherwise authorized by the FAA Administrator, no person may include an alternate airport in an IFR flight plan unless current weather forecasts indicate that, at the estimated time of arrival at the alternate airport, the ceiling and visibility at that airport will be at or above the alternate airport weather minima.

2) Operation under IFR in Class A, B, C, D, or E airspace malfunction reports:

a) The pilot-in-command of each aircraft operated in Class A, B, C, D or E airspace under IFR shall report as soon as practical to ATC any malfunctions of navigational, approach, or communication equipment occurring in flight.

b) In each report the pilot-in-command shall include:
1) aircraft identification.
2) equipment affected.
3) degree to which the capability of the pilot to operate under IFR in the ATC system is impaired; and
4) nature and extent of assistance desired from ATC.

3) When an aircraft has been cleared to maintain ``VFR conditions on top,'' the pilot is responsible to fly at an appropriate VFR altitude, comply with VFR visibility and distance from cloud criteria, and to be vigilant so as to see and avoid other aircraft.

4) Aircraft speed:

a) Unless otherwise authorized by the FAA Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 kt (288 m.p.h.).

b) Unless otherwise authorized or required by ATC, no person may operate an aircraft within Class B, C, or D surface area at an indicated airspeed of more than 200 kt (230 m.p.h.). This paragraph 4b) does not apply to operations within Class B airspace. Such operations shall comply with paragraph 4a) of this section.

c) No person may operate an aircraft in the airspace underlying Class B airspace, or in a VFR corridor designated through Class B airspace, at an indicated airspeed of more than 200 kt (230 m.p.h.).

d) If the minimum safe airspeed for any operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.

5) Operating rules and pilot and equipment requirements for flight in Class B airspace.
a) Operating rules. No person may operate an aircraft within Class B airspace except in compliance with the following rules:
1) No person may operate an aircraft within Class B airspace unless that person has received an appropriate authorization from ATC prior to operation of that aircraft in that area.
2) Unless otherwise authorized by ATC, each person operating a large turbine engine-powered airplane to or from a primary airport shall operate at or above the designated floors while within the lateral limits of the Class B airspace.
3) Any person conducting pilot training operations at an airport within Class B airspace shall comply with any procedures established by ATC for such operations in Class B airspace.
b) Pilot requirements. No person may take off or land a civil aircraft at an airport within Class B airspace or operate a civil aircraft within Class B airspace unless:
1) The pilot-in-command holds at least a private pilot certificate; or
2) The aircraft is operated by a student pilot who has met the requirements (14 CFR Part 61 (Section 61.95)).
c) Communications and navigation requirements. Unless otherwise authorized by ATC, no person may operate an aircraft within Class B airspace unless that aircraft is equipped with:
1) For IFR operations, an operable VOR or TACAN receiver, and
2) For all operations, an operable two-way radio capable of communications with ATC on appropriate frequencies for that Class B airspace.
d) Transponder requirements. No person may operate an aircraft in Class B airspace unless the aircraft is equipped with the applicable operating transponder and automatic altitude reporting equipment.

6) Operating rules and pilot and equipment requirements for operating in Class C airspace.

a) General. For the purpose of this section, the primary airport is the airport designated in 14 CFR Part 71, for which the Class C airspace is designated. A satellite airport is any other airport within the Class C airspace.

b) Deviations. An operator may deviate from any provisions of this section under the provisions of an ATC authorization issued by the ATC facility giving jurisdiction of the Class C airspace. ATC may authorize a deviation on a continuing basis or for an individual flight, as appropriate.

c) Arrivals and overflights. No person may operate an aircraft in Class C airspace unless two-way radio communication is established with the ATC facility having jurisdiction over the Class C airspace prior to entering that area and is thereafter maintained with the ATC facility having jurisdiction over the Class C airspace while within that area.

d) Departures. No person may operate an aircraft within Class C airspace except as follows:
1) From the primary airport or satellite airport with an operating control tower, unless two-way radio communication is established and maintained with the control tower, and thereafter as instructed by ATC while operating in the Class C airspace.
2) From a satellite airport without an operating control tower, unless two-way radio communication is established as soon as practical after departing and thereafter maintained with the ATC facility having jurisdiction over the Class C airspace.

e) Traffic patterns. No person may take off or land an aircraft at a satellite airport within Class C airspace except in compliance with FAA arrival and departure traffic patterns.

f) Equipment requirements. Unless otherwise authorized by the ATC facility having jurisdiction over the Class C airspace, no person may operate an aircraft within Class C airspace unless that aircraft is equipped with the applicable equipment specified in 14 CFR Part 91 (Section 91.215).

7) Except for persons operating gliders below the floor of Class A airspace, no person may operate an aircraft in Class B, C, D, or E airspace of the 48 contiguous States and the District of Columbia above 10,000 feet MSL, excluding that airspace at and below 2,500 feet AGL, unless that aircraft is equipped with an operable radar beacon transponder having at least a Mode 3/A 4096-code capability, replying to Mode 3/A interrogation with the code specified by ATC, and automatic altitude reporting equipment having a Mode C capability that automatically replies to Mode C interrogations by transmitting pressure altitude information in 100-foot increments.

8) Compliance with ATC clearances and instructions:
a) When an ATC clearance has been obtained, no pilot-in-command may deviate from that clearance, except in an emergency, unless an amended clearance is obtained. A pilot-in-command may cancel an IFR flight plan if that pilot is operating in VFR weather conditions outside of Class A airspace. If a pilot is uncertain of the meaning of an ATC clearance, the pilot shall immediately request clarification from ATC.
b) Except in an emergency, no person may operate an aircraft contrary to an ATC instruction in an area in which ATC is exercised.
c) Each pilot-in-command who, in an emergency, deviates from an ATC clearance or instruction shall notify ATC of that deviation as soon as possible.
d) Each pilot-in-command who is given priority by ATC in an emergency shall submit a detailed report of that emergency within 48 hours to the manager of that ATC facility, if requested by ATC.
e) Unless otherwise authorized by ATC, no person operating an aircraft may operate that aircraft according to any clearance or instruction that has been issued to the pilot of another aircraft for radar ATC purposes.

Appendix 1

SIGNALS

CHAPTER 1

DEFINITIONS

Advisory Airspace

The U.S. does not define, it refers to Advisory Service.

Advisory Route

The U.S. does not define, it refers to Advisory Service.

Aerodrome Traffic

The U.S. does not define.

Air Traffic Advisory Service

In the U.S., “Advisory Service” is intended for IFR and VFR aircraft.

Airborne Collision Avoidance System

The U.S. uses traffic alert and collision avoidance system (TCAS).

Aircraft

U.S. uses “Aircraft” to mean the airframe, crew members, or both.

AIRMET

In the U.S., AIRMET stands for Airmen's Meteorological Information which is a concise description of an occurrence or expected occurrence of specified en route weather phenomena that may affect the safety of aircraft operations, but at intensities lower than those that require the issuance of a SIGMET. An AIRMET may be issued when moderate turbulence, low‐level wind shear, strong surface winds greater than 30 knots, moderate icing, freezing level, mountain obscuration, or IFR conditions are occurring or are expected to occur.

Air-report

The U.S. does not normally use the term “air-report.” Pilot weather reports (PIREPs), position, and operational reports are used. PIREPs include reports of strong frontal activity, squall lines, thunderstorms, light to severe icing, wind shear and turbulence (including clear air turbulence) of moderate or greater intensity, volcanic eruptions and volcanic ash clouds, and other conditions pertinent to flight safety. They may include information on ceilings, visibility, thunderstorms, icing of light degree or greater, wind shear and its effect on airspeed, or volcanic ash clouds, but do not usually include air temperature.

Air-taxiing

The U.S. uses “air taxi” below 100 feet above ground level (AGL) and “hover taxi” for this maneuver actual height may vary, and some helicopters may require hover taxi above 25 feet AGL to reduce ground effect turbulence or provide clearance for cargo slingloads.

Air Traffic Flow Management

U.S. defines as Air Traffic Control System Command Center.

Altitude

U.S. uses “Altitude” to mean indicated altitude mean sea level (MSL), flight level (FL), or both.

Approval Request

U. S. uses “APREQ.”

Area control service

The U.S. does not use the term “area control service” to indicate controlled flight in controlled areas.

ATS route

In U.S. domestic airspace, the term “ATS route” is not used. Routes in the U.S. include VOR airways, jet routes, substitute routes, off-airway routes, RNAV routes and colored airways. The U.S. also uses instrument departure procedures (DPs), and standard terminal arrivals (STARs).

Control zone

The U.S. uses “surface area” in place of the ICAO term “control zone.” Surface area is defined as the airspace contained by the lateral boundary of the Class B, C, D or E airspace designated for an airport that begins at the surface and extends upward.

Controlled airspace

The U.S. uses the following definition of controlled airspace found in 14 CFR Section 1.1: “Controlled airspace means an airspace of defined dimensions within which air traffic control service is provided to IFR flights and to VFR flights in accordance with the airspace classification.”

Course, bearing, azimuth, heading, and wind direction

U.S. uses “Course, bearing, azimuth, heading, and wind direction” information and it shall always be magnetic unless specifically stated otherwise.

Cruising level

The U.S. uses the term “cruising altitude.”

Decision altitude

Approach with vertical guidance (VNAV).

Emergency Phase

The U.S. does not utilize classification system of emergency phases

Expedite

U.S. uses “EXPEDITE” by ATC when prompt compliance is required to avoid the development of an imminent situation. Expedite climb/descent normally indicates to a pilot that the approximate best rate of climb/descent should be used without requiring an exceptional change in aircraft handling characteristics.

Flight information centre

In the U.S., the services provided by flight information centers (FICs) are conducted by air traffic control (ATC) facilities, flight service stations (FSSs), and rescue coordination centers (RCCs).

Ground Effect

The U.S. does not define, but is referred to in “Hover Taxi.”

Holding procedure

In the U.S., a hold procedure is also used during ground operations to keep aircraft within a specified area or at a specified point while awaiting further clearance from air traffic control.

Hot Spot

This is a known term, but not specifically defined in 7110.65.

Level

The U.S. uses “altitude” or “flight level” rather than “level.”

Miles

U.S. uses “Miles” to mean nautical miles unless otherwise specified, and means statute miles in conjunction with visibility.

Minute

U.S. uses “minute plus 30 seconds”, except when time checks are given to the nearest quarter minute.

Movement area

In the U.S., the “movement area” is equivalent to the ICAO “maneuvering area” which does not include parking areas.

Near Parallel Runways

In the U.S., these are not defined as non-intersecting runways aligned 15 degrees or less apart

Position Symbol

The U.S. definition differs in that it refers to mode of tracking, rather than position of an aircraft or vehicle

Repetitive flight plan (RPL)

The U.S. uses the term “stored flight plan” for domestic operations.

Runway Incursion

This is a well-known term in NAS, but is not defined in the 7110.65

Stopway

The U.S. does not define a “stopway” as a rectangular area.

Taxiway

a) Aircraft stand taxilane

b) Apron taxiway

c) Rapid exit taxiway

Ref (a), the US does not define as “portion of an apron designated as a taxiway intended to provide access to aircraft stands only.”

Ref (b), the US does not define as “portion of a taxiway system located on an apron, providing taxi route across an apron.”

Ref (c), the US defines as High Speed Taxiway.

Terminal control area

In the U.S., the term “terminal control area” has been replaced by “Class B airspace.” Standard IFR services should be provided to IFR aircraft operating in Class B airspace.

Transition altitude, transition layer, and transition level

In U.S. domestic airspace, transition altitude, layer, and level are not used. U.S. flight levels begin at FL 180 where a barometric altimeter setting of 29.92 inches of mercury is used as the constant atmospheric pressure. Below FL 180, altitudes are based on barometric pressure readings.

Uncertainty Phase

The U.S. does not utilize emergency phase classifications.

Visibility

Definitions are different.

Visual Approach

In the U.S., aircrews may execute visual approaches when the pilot has either the airport or the preceding aircraft in sight and is instructed to follow it.

Will

U.S. uses “Will” means futurity, not a requirement for the application of a procedure.

CHAPTER 4

GENERAL PROVISIONS FOR AIR TRAFFIC SERVICES

In the U.S., flight information and alerting services are provided by ATC facilities, FSSs, and RCCs.

4.4.1.3

The U.S. uses a flight plan format different from the ICAO model discussed in Appendix 2. The U.S. ATS facilities will transmit ICAO repetitive flight plans (RPLs) even though a different format is used for stored flight plans.

4.4.2.1.1

The U.S. accepts flight plans up to 24 hours prior to Estimated Off -Block Time (EOBT).

4.5.6.2

U.S. ATS controllers do not normally include clearance for transonic acceleration in their ATC clearances.

4.5.7.3 and 4.10.4

In U.S. domestic airspace, transition altitude, layer, and level are not used. U.S. flight levels begin at FL180 where a barometric altimeter setting of 29.92 inches of mercury is used as the constant atmospheric pressure. Below FL 180, altitudes are based on barometric pressure readings. QNH and QFE altimeter settings are not provided in domestic U.S. airspace.

4.5.7.5

The flight crew shall read back to the air traffic controller safety-related parts of ATC clearances.

4.6.1.5

The U.S. allows speed adjustments to be assigned in 5 knot increments.

4.6.3.2

The U.S. uses different speed control phraseologies. Specifically, Doc 4444 uses “Maximum Speed” whereas the US uses “Maximum Forward Speed”. Doc 4444 uses “Minimum Clean Speed” whereas the US uses “Slowest Practical Speed.”

4.6.3.7

In the US, speed control is not to be assigned inside Final Approach Fix or 5 NM from runway end.

4.8.2

U.S. Controller phraseology differs slightly and does not include a time check.

4.8.3

ATS units are not required to advise a pilot who has canceled an IFR flight plan that IMC conditions are likely to be encountered along the route of flight; however, if a pilot informs a controller of a desire to change from IFR to VFR, the controller will request that the pilot contact the appropriate FSS.

4.9.1.1

FAA uses different wake turbulence categories and weight groups for wake turbulence separation minimums.

4.9.1.2

FAA uses different wake turbulence categories and weight groups for wake turbulence separation minimums.

Not all FAA facilities are authorized to use the provisions of FAA JO 7110.126.

4.9.2

In the U.S., the word “heavy” is used in all communications with or about heavy jet aircraft in the terminal environment. In the en route environment, “heavy” is used in all communications with or about heavy jet aircraft with a terminal facility, when the en route center is providing approach control service, when the separation from a following aircraft may become less than five miles by approved procedure, and when issuing traffic advisories.

4.10.1.1,
4.10.1.2,
4.10.4.6

Flight levels (at or above 18,000msl, except oceanic) and in feet below 18,000 ft MSL, including around airports (vs. ICAO QFE - height above field/threshold when near airports).

The U.S. has different criteria to make position reports. FAA Order JO 7110.65, 5-1-12. Position Reporting.

4.11.1.3

After an aircraft receives the statement “radar contact” from ATC, it discontinues reporting over compulsory reporting points.

4.12.2 and 4.12.3

The U.S. does not normally use the term “air-report.” Pilot weather reports (PIREPs), position, and operational reports are used. PIREPs include reports of strong frontal activity, squall lines, thunderstorms, light to severe icing, wind shear and turbulence (including clear air turbulence) of moderate or greater intensity, volcanic eruptions and volcanic ash clouds, and other conditions pertinent to flight safety. They may include information on ceilings, visibility, thunderstorms, icing of light degree or greater, wind shear and its effect on airspeed, or volcanic ash clouds, but do not usually include air temperature.

4.13.4

The difference is the length of time for retention.

CHAPTER 5

SEPARATION METHODS AND MINIMA

5.2.1

In U.S. airspace, only conflict resolution (not separation) is provided between IFR and VFR operations. Separation is provided between IFR and Special VFR (SVFR) aircraft only within the lateral boundaries of Class B, C, D, or E control zones (the U.S. term is surface areas) below 10,000 feet MSL.

5.2.1.1

In U.S. Class A and B airspace, separation is provided for all aircraft. In U.S. Class C airspace, separation is provided between IFR and SVFR aircraft; conflict resolution is provided between IFR and VFR operations.

5.4.1.2.1.2

U.S. Lateral separation criteria and minima values differ somewhat.

5.4.2.2.1.1 c/ d

The U.S. uses 22 kt instead of 20 kt and 44 kt instead of 40 kt.

5.4.2.4.1

FAA uses Mach number technique for application of longitudinal separation with turbojet aircraft only.

5.4.2.5.1

FAA uses Mach number technique for application of longitudinal separation with turbojet aircraft only.

5.4.2.7.3.2 d)2).

The FAA's Advanced Technologies and Oceanic Procedures (ATOP) automation platform is designed to ensure that separation will not decrease below required minima for same track aircraft should either the reference or maneuvering aircraft turn during the ITP. This allows the controller to issue a clearance to perform an ADS-B ITP climb/descent maneuver if required separation is maintained or increased and either the reference or maneuvering aircraft has a turn in its flight plan.

5.5.2

Whenever the other aircraft concerned are within 5 minutes flying time of the holding area.

5.6

U.S. Allows 2 minute separation standard when courses diverge within 5 minutes after departure.

5.7

U.S. Requires departing aircraft to be established on a course diverging by at least 45 degrees from the reciprocal of the final approach course.

5.8.2.1

FAA uses different wake turbulence categories and differing minima.

FAA requires 3 minutes separation for a Large or Heavy aircraft landing behind a Super aircraft.

5.8.3.1

FAA uses different wake turbulence categories and differing minima.

For Heavy, Large, or Small aircraft departing behind a Super aircraft, taking off from the same runway or a parallel runway separated by less than 2,500 feet, FAA requires that takeoff clearance may not be issued to following aircraft until 3 minutes after the preceding aircraft begins takeoff roll.

5.8.3.2

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA time‐based wake turbulence separation minima differs from ICAO standards.

5.8.3.4

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA time‐based wake turbulence separation minima differs from ICAO standards.

5.8.4.1

The U.S. includes B757 in heavy category for wake turbulence purposes. DOC 4444 does not stipulate.

For Heavy, Large, or Small aircraft taking off behind a departing Super aircraft on an intersecting runway or nonintersecting runway if flight paths will cross; FAA requires 3 minutes wake turbulence separation.

5.8.4.2

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA time‐based wake turbulence separation minima differs from ICAO standards.

5.8.4.3

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA time‐based wake turbulence separation minima differs from ICAO standards.

5.8.5.2

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA time‐based wake turbulence separation minima differs from ICAO standards.

CHAPTER 6

SEPARATION IN THE VICINITY OF AERODROMES

6.3.2.4

In the U.S.:
a) An altitude to maintain is not normally issued in conjunction with a climb via clearance. If no altitude is assigned, pilots should climb to the “Top Altitude” depicted on the SID. ATC will assign an altitude when the “Top Altitude” is identified as “Assigned by ATC”;
b) While on a climb via clearance, if a new clearance is issued to an altitude to maintain (for example, “Climb and maintain flight level one eight zero"), all published altitude restrictions on the SID are cancelled;
c) A clearance to “climb via SID except maintain” cancels all remaining published altitudes on the SID that are above the cleared altitude;
d) A clearance to “climb via SID except cross” instructs pilots to comply with the issued crossing restriction and all other restrictions on the SID;
e) The phraseology “climb unrestricted" is not used. A climb and maintain (altitude) authorizes the pilot to climb unrestricted to the assigned altitude.

6.3.2.5

In the U.S., if the communications failure occurs in IFR conditions, or if VFR cannot be complied with, each pilot shall continue the flight according to the following requirements:

Route

a) By the route assigned in the last ATC clearance received;

b) If being radar vectored, by the direct route from the point of failure to the fix, route, or airway specified in the vector clearance;

c) In the absence of an assigned route, by the route that ATC has advised may be expected in a further clearance; or

d) In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance, by the route filed in the flight plan.

Altitude - At the highest of the following altitudes or flight levels for the route segment being flown:

a) The altitude or flight level assigned in the last ATC clearance received;

b) The minimum altitude as prescribed in 14 CFR Part 91 (Section 91.121(c)) for IFR operations; or

c) The altitude or flight level ATC has advised may be expected in a further clearance.

6.3.3.3

Arriving aircraft - delay of 10 minutes or more.

6.5.2.4

In the U.S.:
a) A descend via clearance authorizes pilots to descend at pilot discretion to meet published restrictions on a STAR. Pilots are not authorized to descend without being issued an altitude;
b) An altitude to maintain is not normally issued in conjunction with a descend via clearance. If no altitude is issued, the pilot is expected to descend to the lowest published altitude on the STAR;
c) While on a descend via clearance, if a new clearance is issued to an altitude to maintain (for example, “Descend and maintain flight level two eight zero"), all published altitude restrictions on the STAR are cancelled;
d) A clearance to “descend via STAR except maintain” cancels all remaining published altitudes on the STAR that are below the cleared altitude;
e) A clearance to “descend via STAR except cross” instructs pilots to comply with the issued crossing restriction and all other restrictions on the STAR;
f) The phraseology “descend unrestricted" is not used. A descend and maintain (altitude) authorizes the pilot to descend unrestricted to the assigned altitude.

6.5.3.1

The 7110.65 does not stipulate flight crew concurrence of Controller initiated Visual Approach.

6.5.3.5

U.S. requires ATC to inform following aircraft behind Heavy/B757 aircraft of manufacturer and model information.

6.5.5.2

Onward clearance time. 7110.65 PG EXPECT FURTHER CLEARANCE (TIME)- The time a pilot can expect to receive clearance beyond a clearance limit.

6.7.3.1.2

U.S. has no criteria for separate radar controllers in conducting Parallel approaches.

6.7.3.2.1 a) Table 6-1

When conducting Dual and Triple Simultaneous Independent Approaches using High Update Rate Surveillance, the FAA allows the minimum distance between runway centerlines to be 3100 feet.

6.7.3.2.4 c

The United States does not require the final vector to final to enable the aircraft to be established on the final approach course track, in level flight for at least 3.7 km (2.0NM) prior to intercepting the glide path or vertical path for the selected instrument approach procedure.

6.7.3.2.10

U.S. has no parallel approach obstacle assessment surfaces (PAOAS) Criteria.

6.7.3.2.10

The U.S. has no criteria for a “45 degree track”.

6.7.3.2.11 (a)

The U.S. has no criteria for both controllers to be advised when visual separation is applied.

6.7.3.4.1 (f)

The U.S. requires that adjacent missed approach procedures do not conflict.

6.7.3.6.3 (b)

The U.S. has no surveillance radar approach (SRA).

6.7.3.6.3 (c)

In the U.S., aircrews may execute visual approaches when the pilot has either the airport or the preceding aircraft in sight and is instructed to follow it. A contact approach is one wherein an aircraft on an IFR flight plan, having an air traffic control authorization, operating clear of clouds with at least 1 mile flight visibility and a reasonable expectation of continuing to the destination airport by visual reference in those conditions, may deviate from the instrument approach procedure and proceed to the destination airport by visual reference to the surface. This approach will only be authorized when requested by the pilot and the reported ground visibility at the destination airport is at least 1 statute mile.

CHAPTER 7

PROCEDURES FOR AERODROME CONTROL SERVICE

7.4.1.1

U.S. has no start up procedures, taxi clearance.

7.4.1.2.1 (f)

U.S. does not require time check prior to taxi.

7.6.3.1.1.3

In the U.S. the FAA does not publish standard taxi routes to be used at an airport in the national AIP.

7.6.3.2.3.2

In the U.S., for movements of other than aircraft traffic (i.e., vehicles, equipment, and personnel), steady green means cleared to cross, proceed, go; flashing green is not applicable; flashing white means return to starting point on airport; and alternating red and green means a general warning signal to exercise extreme caution.

7.6.3.2.3.3

U.S. controllers do not flash runway or taxiway lights to instruct aircraft to “vacate the runway and observe the tower for light signal.”

7.10.2

In the U.S., landing clearance to a succeeding aircraft in a landing sequence need not be withheld if the controller observes the positions of the aircraft and determines that prescribed runway separation will exist when the aircraft crosses the landing threshold. Controllers issue traffic information to the succeeding aircraft if it has not previously been reported.

7.11.4 and 7.11.6

U.S. category 1, 2, & 3 (SRS) aircraft weights differ. Separation standards are greater, due to increased size and weight categories.

U.S. does not specify separation standards on taxiways.

7.15

Special VFR operations may be conducted in the U.S. under the following weather minimums and requirements below 10,000 feet MSL within the airspace contained by the upward extension of the lateral boundaries of the controlled airspace designated to the surface for an airport. These minimums and requirements are found in 14 CFR Section 91.157.

Special VFR operations may only be conducted:
(1) With an ATC clearance;
(2) Clear of clouds;
(3) Except for helicopters, when flight visibility is at least 1 statute mile; and

(i) The person being granted the ATC clearance meets the applicable requirements for instrument flight; and
(ii) The aircraft is equipped as required in 14 CFR Sec. 91.205(d).

7.15

No person may take off or land an aircraft (other than a helicopter) under special VFR:

(1) Unless ground visibility is at least 1 statute mile; or

(2) If ground visibility is not reported, unless flight visibility is at least 1 statute mile.

CHAPTER 8

ATS SURVEILLANCE SERVICES

8.5.5.1

U.S. validation of mode C readouts allow up to 300 feet variance from pilot reported altitudes.

8.6.5.2

The U.S. has not implemented cold temperature corrections to the radar minimum vectoring altitude.

8.7.3.2 (b)

8.7.3.4

Separate a Heavy aircraft operating directly behind a Super aircraft or following a Super aircraft conducting an instrument approach by 6 miles unless the Super aircraft is operating above FL 240 and above 250 knots.

Consider parallel runways less than 2,500 feet apart as a single runway because of the possible effects of wake

8.7.3.5

FAA Consolidated Wake Turbulence (CWT) is based on nine weight groups. FAA distance‐based wake turbulence separation minima differs from ICAO standards.

8.7.3.6

Separate a Heavy aircraft operating directly behind a Super aircraft or following a Super aircraft conducting an instrument approach by 6 miles unless the Super aircraft is operating above FL 240 and above 250 knots.

CHAPTER 9

FLIGHT INFORMATION SERVICE AND ALERTING SERVICE

9.1.3.2.1

ATC facilities in the CONUS will no longer receive AIRMET advisories to broadcast and will therefore not broadcast AIRMETs; operators have other methods, such as the G-AIRMET, of receiving AIRMET information over the CONUS.

9.1.3.7

The U.S. does not have special procedures for the transmission of information to supersonic aircraft.

9.1.4.1.1

CHAPTER 10

COORDINATION

10.1.3.1

Except for a VFR aircraft practicing an instrument approach, an IFR approach clearance in the U.S. automatically authorizes the aircraft to execute the missed approach procedure depicted for the instrument approach being flown. No additional coordination is normally needed between the approach and en route controllers. Once an aircraft commences a missed approach, it may be radar vectored.

10.1.4.2.2

U.S. does not require ETA to be forwarded at least 15 minutes prior to ETA.

CHAPTER 11

AIR TRAFFIC SERVICES MESSAGES

11.1.2

U.S. uses different emergency messages. FAA Order JO 7110.10, Chapter 3, Emergency Services.

CHAPTER 12

PHRASEOLOGIES

12.2.7

US ATC does not allow conditional clearances described

for example:

“SAS 941, BEHIND DC9 ON SHORT FINAL, LINE UP BEHIND.”

Note - This implies the need for the aircraft receiving the conditional clearance to identify the aircraft or vehicle causing the conditional clearance.

12.3.1.2 m)
General to
require action when convenient

m) WHEN READY (instruction);

U.S. does not use this phraseology. 7110.65 4-5-7. ALTITUDE INFORMATION PHRASEOLOGY CLIMB/ DESCEND AT PILOT'S DISCRETION 1. The pilot is expected to commence descent upon receipt of the clearance and to descend at the suggested rates specified in the AIM, 4-4-9, Adherence to Clearance, until reaching FL 280. At that point, the pilot is authorized to continue descent to FL 240 within the context of the term “at pilot's discretion” as described in the AIM. f. When the “pilot's discretion” portion of a climb/descent clearance is being canceled by assigning a new altitude, inform the pilot that the new altitude is an “amended altitude.” EXAMPLE- “American Eighty Three, amend altitude, descend and maintain Flight Level two six zero.”

12.3.1.2 (n) MAINTAIN OWN SEPARATION AND VMC [FROM (level)]

[TO (level)]; and

(o) MAINTAIN OWN SEPARATION AND VMC ABOVE (or BELOW, or TO) (level);

U.S. does not use “maintain own separation and VMC 'from,' 'above,' or 'below' . . . ,” U.S. controllers say “maintain visual separation 'from' that traffic.”

Meteorological conditions are expressed in terms of visibility, distance from cloud, and ceiling, equal to or better than specified minima.

12.3.1.2 aa) Clearance to cancel level restriction(s) of the vertical profile of a SID during climb.” (z) CLIMB TO (level) [LEVEL RESTRICTION(S) (SID designator) CANCELLED (or) LEVEL RESTRICTION(S)

(SID designator) AT (point) CANCELLED];

The U.S. does not have specific phraseology examples that cover this issue. However, phraseology contained in the 7110.65 covers how to change altitudes and altitude restriction in a SID.

12.3.1.2 ff) Clearance to cancel level restriction(s) of the vertical profile of a STAR during descent.

gg) DESCEND TO (level) [LEVEL RESTRICTION(S) (STAR

designator) CANCELLED (or) LEVEL RESTRICTION(S)

(STAR designator) AT (point) CANCELLED].

The U.S. does not have specific phraseology examples that cover this issue. However, phraseology contained in the 7110.65 covers how to amend or cancel altitude restrictions.

12.3.1.2 a) 2)

TO AND MAINTAIN BLOCK (level) TO (level);

U.S. uses “MAINTAIN BLOCK (altitude) THROUGH (altitude).”

7110.65, Para 4-5-7. g. ALTITUDE INFORMATION

12.3.1.6

CHANGE OF CALL SIGN

U.S. has no phraseology or approved procedure to advise aircraft to change call signs.

12.3.1.8 b)

METEOROLOGICAL CONDITIONS

In the U.S., the criterion for a variable wind is: wind speed greater than 6 kt and direction varies by 60 degrees or more. If the wind is>1 kt but <6 kt, the wind direction may be replaced by "VRB" followed by the speed or reported as observed. “VRB” would be spoken as “wind variable at .”

12.3.1.8 d), e), and f)

METEOROLOGICAL CONDITIONS

U.S. controllers do not give wind speed, visibility, or RVR values in metric terms. RVR values are given in 100- or 200-foot increments while RW values are given in Venule increments.

12.3.1.8 j)

U.S. controllers do not use the term “CAVOK.” However, the ceiling/sky condition, visibility, and obstructions to vision may be omitted if the ceiling is above 5,000 feet and the visibility is more than 5 miles.

12.3.1.8 l) and m)

In the US, controllers and pilots exchange altimeter setting by reference to inches Hg. ICAO describes altimeter setting by reference to millibars, QNH or QFE. (where QNH - above mean sea level and QFE - height above aerodrome)

12.3.2.2
INDICATION OF ROUTE AND CLEARANCE LIMIT

U.S. will issue a clearance “direct” to a point on the previously issued route. PHRASEOLOGY CLEARED DIRECT (fix). NOTE Clearances authorizing “direct” to a point on a previously issued route do not require the phrase “rest of route unchanged.” However, it must be understood where the previously cleared route is resumed. When necessary, “rest of route unchanged” may be used to clarify routing. 7110.65, paragraph 4-4-1. ROUTE USE & 4-2-5. ROUTE OR ALTITUDE AMENDMENTS 3.

TAKE-OFF CLEARANCE when take-off clearance has not been complied with

c) Vacate

12.3.4.20 RUNWAY VACATING AND COMMUNICATIONS AFTER LANDING

b)

U.S. uses CLEAR OF THE RUNWAY

a. Taxiing aircraft, which is approaching a runway, is clear of the runway when all parts of the U.S. uses aircraft are held short of the applicable runway holding position marking.

b. A pilot or controller may consider an aircraft, which is exiting or crossing a runway, to be clear of the runway when all parts of the aircraft are beyond the runway edge and there are no restrictions to its continued movement beyond the applicable runway holding position marking.

c. Pilots and controllers shall exercise good judgment to ensure that adequate separation exists between all aircraft on runways and taxiways at airports with inadequate runway edge lines or holding position markings.

12.3.4.11 (e)

FAA Order 7110.65, Code Monitor, paragraph 5-2-13.

15.3.3 b) 1, 2

7110.65 defers to the AIM for what to expect an aircraft to do when loss of two-way communication has been encountered. The expectations in the AIM differ from what a pilot is expected to do in accordance with PANS-ATM 15.3.3 b) 1 and 2.

The U.S. does not specify a time that an aircraft would maintain its last assigned heading, speed, or altitude. PANS-ATM uses 20 min. in a non-radar environment and 7 min. in a radar environment.

15.3.10

When neither communications nor radar contact can be established for 30 minutes (or prior, if appropriate), U.S. controllers will consider an aircraft overdue and will initiate overdue aircraft procedures including reporting to the ARTCC or FSS.

15.4.1

U.S. does not use the terms “strayed” or “unidentified” aircraft. 7110.65, paragraph 10-3-1. OVERDUE AIRCRAFT

15.5.3.2

Separate known aircraft from the aircraft dumping fuel as follows:

a. IFR aircraft by one of the following:

1. 1,000 feet above it; or in accordance with paragraph 4-5-1, Vertical Separation Minima, whichever is greater.
2. 2,000 feet below it.
3. 5 miles radar.
4. 5 miles laterally.

b. VFR radar‐identified aircraft by 5 miles and in accordance with paragraph 5-6-1, Application.

15.7.1.1

The PANS-ATM states: “If, during an emergency situation, it is not possible to ensure that the applicable horizontal separation can be maintained, emergency separation of half the applicable vertical separation minimum may be used” Pilots must be advised that emergency separation is being applied and traffic information must be given.

There is no equivalent emergency separation procedure in the U.S.

APPENDIX 1

ITEM 9

ICAO aircraft wake turbulence categories (heavy, medium, light) and FAA weight classes (heavy, large, small) differ. Also, for landing aircraft, wake turbulence separation is defined differently. The U.S. makes special provisions for any aircraft landing behind a B-757 (4 miles for a large aircraft behind or 5 miles for a small aircraft behind).

ITEM 15

U.S. ATS units do not accept cruising speeds nor filed altitudes/flight levels in metric terms. The U.S. accepts filed Mach Number expressed as M followed by 3 figures.

PART I (Core SARPs)

Chapter 2

General Provisions

2.2

The U.S. has implemented a quality management system (QMS) for the majority of the meteorological information supplied to users. WAFC Washington and MWO Kansas City (a.k.a. Aviation Weather Center) are ISO 9000. MWOs Anchorage and Honolulu and all 122 Weather Forecast Offices have a QMS that is governed under the following National Weather Service (NWS) directives: NWS Instruction 10-1601 (Verification), NWS Instruction 10-1602 (Service Evaluation), NWS Instruction 10-1606 (Service Assessment), NWS Instruction 10-1607 (Office Evaluation), and NWS Instruction 10-815 (Aviation Meteorologist Training and Competencies). No QMS is in place for the augmentation of the surface observing program.

Chapter 3

World Area Forecast System and Meteorological Offices

3.2.1

SIGWX forecasts are not disseminated in IWXXM form (Appendix 2, 1.2.1.3).

3.7 b)

Tropical Cyclone Advisories issued by Miami and Honolulu TCACs differ from Table A2-2 in Appendix 2 as they contain forecasts valid at 3-, 9-, 15- 21- and 27-hours instead of 6-, 12-, 18-, and 24-hours.

3.8.1 a) 2)

Space weather advisories are not issued for communication via satellite (SATCOM).

Chapter 4

Meteorological Observations and Reports

4.3.2 a)

The U.S. does not issue local routine reports or local special reports. This difference is applicable to subsequent paragraphs that relate to the provision of local routine and special reports in Annex 3. The U.S. provides METAR to departing and arriving aircraft and provides wind and altimeter information in accordance with Federal Aviation Administration (FAA) Order JO 7110.65Y Section 9 (3-9-1) and Section 10 (3-10-1).

4.5.1 d)

This field is also used to denote a correction to the METAR/SPECI by “COR.”

4.6.2.1

The U.S. reports visibility in statute miles.

4.6.3.3

RVR values in the METAR/SPECI code forms are reported in feet.

4.6.4.1

The U.S. automated surface observing systems (ASOS, AWOS) do not generate an automated report for the occurrence of drizzle or freezing drizzle. The ASOS does allow the manual augmentation of these elements to the observations.

4.6.7

The U.S. provides atmospheric pressure in inches of mercury. METAR and SPECI contains an Altimeter Setting (A) instead of QNH, for example, A3010 for 30.10 inches of mercury. The U.S. does not provide QFE.

Chapter 5

Aircraft observations and reports

5.5

Urgent Pilot Reports (UUA) are used in lieu of Special Aircraft Observations, to include Hail, Low Level Wind Shear (within 2,000 ft of surface), severe icing, severe and extreme turbulence, tornado, funnel cloud or waterspout, and volcanic eruption and/or volcanic ash. In addition, Pilot Reports (UA) and UAA identify the location of the weather phenomenon by NAVAIDS.

Pilot Reports are used in lieu of Special Aircraft Observations, to include moderate turbulence and moderate icing. Braking action may be included in the remarks section of the UUA/UA, but is reported to air traffic control when worse than reported.

Chapter 6

Forecasts

6.3.1

Landing forecasts are provided by the TAF.

6.3.3

The U.S. does not provide trend forecasts.

6.5

The U.S. provides an Area Forecast (FA) and Graphical Forecast for Aviation (GFA) in place of a GAMET. The FA is provided by MWOs Anchorage and Honolulu while the GFA is provided by WFO Kansas City. The format and content of the FA and GFA differs from the GAMET.

The FA and GFA are valid from the surface up to FL450. The GFA is a web-based interactive information service.

SIGMET and AIRMET Information, Aerodrome Warnings and Wind Shear Warnings

7.1.3

The period of validity is 4‐hour for volcanic ash SIGMETs issued by the MWO Kansas City over the contiguous U.S.

7.1.4

Volcanic ash SIGMETs issued by the MWO Kansas City over the contiguous U.S. are coordinated with the VAAC but are not based solely on the advisory information due to the period of validity.

7.1.6

Volcanic ash SIGMETs issued by the MWO Kansas City over the contiguous U.S. are updated every 4-hours.

7.2.1

The vertical domain of U.S. AIRMETs is from the surface up to FL450. The content, order, and format of U.S. AIRMETs are not in accordance with Table A6-1A due to national practices, which are described in National Weather Service Instruction 10-811. Traditional Alphanumeric Code AIRMETs are no longer in use over the contiguous U.S., but continue to be used over Alaska and Hawaii. The AIRMET sequence number is not restricted to FIRs. AIRMETs in the U.S. are issued on a routine schedule when moderate turbulence, non‐convective low‐level wind shear, strong surface winds greater than 30 knots, moderate icing, freezing level, mountain obscuration, or IFR conditions are occurring or are expected to occur. The US does not issue AIRMETs for thunderstorms. AIRMET information is not restricted to FL100 and below and can be provided up to FL450 depending on the phenomena. The U.S. does not use flight level (FL) when describing the altitudes in AIRMETs except for those above FL180. The U.S. uses VORs instead of latitude and longitude to describe the area within an AIRMET.

7.2.3

AIRMETs over the contiguous U.S. and Hawaii are valid for 6 hours and are issued every 6 hours on a scheduled basis. AIRMETs over Alaska are valid for 8 hours and are issued every 8 hours on a scheduled basis. The vertical domain of AIRMETs is from the surface up to FL450. The U.S. also provides a graphical version of the AIRMET (G-AIRMET) that contains 3-hourly time steps valid from 0-hour to 12-hours.

7.4.1

The U.S. does not provide wind shear warnings. The U.S. believes wind shear alerts are timelier to flight crews in landing and takeoff than wind shear warnings and thus provide a greater level of safety. In addition, the information is duplicative in nature in that wind shear warnings could be delayed while wind shear alerts are provided via automated systems that allow for immediate data link to flight crews through ATS systems.

Chapter 9

Service for operators and flight crew members

9.2.3 & 9.2.4

U.S. meteorological offices have no means to communicate directly to flight crews if there is a divergence in the forecast from what is provided in the flight document folder.

9.3.3

U.S. meteorological offices have no means to provide updates to flight document folders or to contact the operator.

APPENDICES and ATTACHMENTS

APPENDIX 2

Technical specifications related to global systems, supporting centers and meteorological offices

Table A2-2

U.S. TCACs do not provide observed CB clouds in the tropical cyclone advisory message.

5.1.4

U.S. TCACs do not provide observed CB clouds in the tropical cyclone advisory (TCA) message. The U.S. does not provide a graphical version of the TCA.

APPENDIX 3

Technical specifications related to meteorological observations and reports

2.1.2

U.S. METARs and SPECIs are not issued in accordance with Table A3-2 due to national practices, which are described in FAA Order JO 7900.5 and Federal Meteorological Handbook No. 1 (FMH-1). Ranges and resolution for numerical elements included in METAR and SPECI differ from Table A3-5.

2.2

The U.S. does not use the term CAVOK in meteorological reports.

2.3

U.S. practices require SPECI for wind shift when wind direction changes by 45 degrees or more in less than 15 minutes and the wind speed is 10 knots or more throughout the wind shift. Practices do not require SPECI for increases of mean surface wind speed. Practices require SPECI for squall, where squall is defined as a strong wind characterized by a sudden onset in which the wind speed increases at least 16 knots and is sustained at least 22 knots or more for at least one minute. Practices do not require SPECI for wind direction changes based on local criteria. Practices do not require SPECI for the onset, cessation or change in intensity of: freezing fog; low drifting dust, sand or snow; blowing dust, sand or snow (including snowstorm); dust storm; or sandstorm. Practice provides a SPECI when a layer of clouds or obscurations aloft is present below 1000 ft and no layer aloft was reported below 1000 ft in the preceding report. A SPECI is also reported when the ceiling (ceiling is defined in the U.S. as the lowest broken or overcast layer) decreases or increases at these markers: 3000, 1500, 1000, 500 ft or lowest published instrument approach procedures. SPECI is made when referenced weather phenomena cause changes in the visibility, ceiling, sky condition, freezing precipitation (including intensity), hail, or ice pellets.

2.3.3 c)

The U.S. does not issue SPECI for the equivalents in feet of 50, 175, 300, 550 or 600 meters. RVR is measured in increments of 100 feet up to 1,000 feet, increments of 200 feet from 1,000 feet to 3,000 feet, and increments of 500 feet above 3,000 feet to 6,000 feet. SPECI is made when the highest value from the designated RVR runway decreases to less than or if below, increases to equal or exceeds 2,400 feet during the preceding 10 minutes.

3.1.4

Practice to disseminate SPECI for improving conditions as soon as possible after the observation.

4.1.1.2

The U.S. does not provide wind representatives for specific runways but does provide a wind representative for the aerodrome.

4.1.3.1 b)

The United States provides a 2-minute average wind observation for the METAR/SPECI.

4.1.5

The wind direction may be considered variable if, during the 2-minute evaluation period, the wind speed is 6 knots or less. Also, the wind direction must be considered variable if, during the 2-minute evaluation period, it varies by 60 degrees or more when the wind speed is greater than 6 knots. Practices define wind gusts as rapid fluctuations in wind speed with a variation of 10 knots or more between peaks and lulls. Wind speed data for the most recent 10 minutes is examined and a gust, the maximum instantaneous wind speed during that 10-minute period, is reported if the definition above is met during that period.

4.2.4.4

Surface visibility is derived from an automated sensor system and is reported as prevailing visibility in the METAR and SPECI. Tower visibility is the prevailing visibility determined from the airport control tower at locations that also report surface visibility. When visibility is reported from both surface and tower, the lower value (if below 4 miles) is reported in the body of the METAR/SPECI and the other value is reported in the remarks section of the METAR/SPECI.

4.3.4b)

The U.S. does not report in METAR or SPECI marked discontinuity values when RVR passes through values of 800, 550, 300 and 175 meters.

4.3.6

The U.S. reports RVR in increments of 100 feet up to 1,000 feet, increments of 200 feet from 1,000 feet to 3,000 feet, and increments of 500 feet above 3,000 feet to 6,000 feet. The U.S. reports RVR for a single designated runway in the METAR/SPECI. RVR tendency is not reported.

4.4

The following weather elements are augmented manually at designated automated stations observation sites: FC, TS, GR, GS, and VA. At selected airports, additional present weather elements may be provided. With the exception of volcanic ash, present weather is reported when prevailing visibility is less than 7 statute miles or considered operationally significant. Volcanic ash is always reported when observed.

4.4.2.3

GR refers to all hail. All reports of hail include hailstone size diameter in the Remarks (RMK) section of the METAR/SPECI in increments of 1/4 inch. If no hail size is reported it will be assumed to be small hail. Small hail will result in the issuance of a SPECI. GS is used only when snow pellets are observed. The U.S. automated surface observing systems (ASOS, AWOS, AWSS) do not generate an automated report for the occurrence of drizzle or freezing drizzle. The ASOS and AWSS do allow the manual augmentation of these elements to the observations.

4.4.2.8

The practice with respect to the proximity indicator VC is between 5 to 10 statute miles from point of observation.

4.4.2.10

The U.S. does not use “//” to denote the present weather is missing at an automated observing site. The U.S. uses “PWINO” in the remarks section of the METAR and SPECI to denote the present weather is unavailable.

4.5.3

Practice does not provide adjustments for runway thresholds more than 50 feet lower than aerodrome elevation. Applies to KDEN runways 7, 8, 16L, 16R, 17L, 17R, 25, 26, 34L, 34R and 35R, KCLT runway 36C, KCVG runway 36C, KDFW runways 13L and 31R, KLAS runways 25L and 25R, KMEM runways 9 and 18C, KPIT runways 10R, 28L and 32, KSTL runways 6, 12R, 24 and 29, KIND runway 5L, and KRDU runway 5L.

4.5.4

The United States reports only up to 3 layers at automated sites and up to 6 layers at manual sites. Cloud layer amounts are a summation of layers at or below a given level, utilizing cumulative cloud amount. In addition, at automated sites, which are unstaffed, cloud layers above 12,000 ft are not reported. At staffed automated sites, clouds above 12,000 ft may be augmented. CAVOK and NSC are not used. In addition, the US does not use "///" when cloud type cannot be observed; "NCD" when no clouds are detected; or "//////" for CB or TCU when not detected by automated observing systems. In the US, the symbol "///", when used in the cloud section of METAR, refers to a mountain station where the layer is below the station level. The US refers to a cloud Ceiling, with the abbreviation CIG, as the lowest layer reported as broken or overcast, or the vertical visibility into an indefinite ceiling. The US refers to a Variable Ceiling in the METAR and SPECI Remarks (RMK) when the ceiling layer is variable and below 3,000 feet. The range of variability (V) between the two values is included in the Remark, for example “CIG 005V010”.
This difference is also applicable to Table A3-2, METAR and SPECI.

4.5.4.6 d)

The United States does not provide supplemental section for the METAR rather the U.S provides a Remarks Section (RMK) that contains similar information. U.S. METAR and SPECI contain Remarks that are intended for all operational decision-making.
FMH-1 contains the complete description of Remarks. Wind shear is not included in the METAR/SPECI code form in the U.S remarks. Practice is to not use RE and to use beginning and ending times in the remarks section for only recent precipitation and thunderstorms. Sea-surface temperature, the state of the sea and state of the runway are not provided in the METAR/SPECI code form in the U.S. remarks.

4.8

The United States does not provide supplemental section for the METAR rather the U.S provides a Remarks Section (RMK) that contains similar information. U.S. METAR and SPECI contain Remarks that are intended for all operational decision-making. FMH-1 contains the complete description of Remarks. Wind shear is not included in the METAR/SPECI code form in the U.S remarks. Practice is to not use RE and to use beginning and ending times in the remarks section for only recent precipitation and thunderstorms.

Sea-surface temperature, the state of the sea and state of the runway are not provided in the METAR/SPECI code form in the U.S. remarks.

APPENDIX 4

Technical specifications related to aircraft observations and reports

3.1.3

The U.S. MWOs do not disseminate special air observations and reports.

APPENDIX 5

Technical specifications related to forecasts

1.1

NWS TAFS are not issued in accordance with Table A5-1 due to national practices, which are described in National Weather Service Instruction 10-813.

1.2

Forecast visibility increments used consist of 1/4 mile from 0 (zero) to 1 mile, 1/2 mile from 1 to 2 miles, and 1 mile above 2 miles. Note: miles are statute miles.

Practice defines light winds as less than or equal to 6 knots for using VRB in TAF. Practices require forecast of non-convective low-level wind shear within 2,000 feet of the ground in the Optional Group. The NWS does not use CAVOK and NSC in the TAF. NWS practices do not include TCU in the TAF.

1.3

Change groups and amendment criteria below 1/2 statute mile (800 meters) are not used. The 100-foot (30 meter) change group and amendment criterion is not used. Practice requires TAF to be amended for a 30-degree change with an accompanying wind of 12 knots or greater; for a 10 knot wind increase only when the original was 12 knots or greater; and for a 10 knot wind gust, regardless of mean wind speed. The NWS does not use the change indicator “BECMG.” The period of time covered by a TEMPO group is normally kept to a minimum but could be up to four (4) hours. Practice does not amend TAFs for moderate or heavy precipitation.

1.4

The NWS does not use “PROB 40” in the TAF. “PROB 30” will not be used in the first nine (9) hours of every TAF's valid period, including amendments.

APPENDIX 6

Technical specifications related to SIGMET and AIRMET information, aerodrome warnings and wind shear warnings and alerts

Table A6-1A, Template for SIGMET and AIRMET messages

The US does not provide SIGMET and AIRMET information in accordance with Table A6-1A, template for SIGMET and AIRMET messages.

1.1

The content and format of U.S. SIGMETs are not in accordance with Table A6-1A due to national practices, which are described in National Weather Service Instruction 10-811. SIGMETs in the conterminous U.S. (CONUS), i.e. except Alaska and Hawaii, are often valid for more than one FIR. The SIGMET sequence number is not restricted to FIRs. U.S. practices are to issue SIGMET for mountain wave only when accompanied by severe turbulence. Within the CONUS and coastal waters, convective SIGMETs are issued in lieu of SIGMETS for thunderstorms. SIGMETs are issued by alphanumeric series, e.g., Kilo 1,2,3 etc. SIGMET messages in the CONUS use VORs in place of lat/long and do not reference FIRs. The U.S. does not use flight level (FL) when describing the altitudes in SIGMETs except for those above FL180.
The U.S. does not include a specific forecast position for the end of the SIGMET and AIRMET validity time, other than TC and VA. The U.S. does not issue a SIGMET for radioactive clouds. Within the FIRs over the CONUS and coastal waters, convective SIGMETs are issued in lieu of SIGMETS for Tropical Cyclones (TC).

2.1

The content, order and format of U.S. AIRMETs are not in accordance with Table A6-1A due to national practices, which are described in National Weather Service Instruction 10-811. AIRMETs in the conterminous U.S. are often valid for more than one FIR. The AIRMET sequence number is not restricted to FIRs. AIRMETs in the U.S. are issued on a routine schedule for icing, turbulence, sustained surface winds, ceiling/visibility and mountain obscuration. The US does not issue AIRMETs for thunderstorms. AIRMET information is not restricted to FL100 and below and can be provided up to FL450 depending on the phenomena. The U.S. does not use flight level (FL) when describing the altitudes in AIRMETs except for those above FL180. The U.S. uses VORs instead of latitude and longitude to describe the area within an AIRMET.

 

4.2

The U.S. issues convective SIGMETs in lieu of SIGMETs for thunderstorms over the CONUS. The US does not issue AIRMETs for thunderstorms. Convective SIGMETs are issued hourly for the East, Central, and Western U.S. and thus they do not indicate the FIR. Connective SIGMETs have an outlook section.

4.2.1

U.S. practices allow for the use of term widespread (WDSPR) for more than 50 percent of the area.
Convective SIGMET criteria over the CONUS are:
a. A line of thunderstorms at least 60 miles long with thunderstorms affecting at least 40 percent of its length.
b. An area of active thunderstorms judged to have a significant impact on the safety of aircraft operations, covering at least 40 percent of the area concerned, and exhibiting a very strong radar reflectivity intensity or a significant satellite or lightning signature.
c. Embedded or severe thunderstorm(s) expected to occur for more than 30 minutes during the valid period regardless of the size of the area.

4.2.9

The U.S. criteria for heavy sandstorm and dust storm is visibility less than or equal to 1/4 SM (400 m). The U.S. criteria for moderate sandstorm and dust storm is visibility greater than 1/4 SM and less than or equal to 1/2 SM (800 m).

5.1

The U.S. issues airport warning messages similar to the ICAO format (Table A6-2, Template for aerodrome warnings) only at selected airports based on criteria per a bilateral agreement between the airport authority and the NWS Forecast Office.

6.2.1

The U.S. does not provide wind shear warnings.

Flight operations

3.4.3.5.3

No person may begin a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed—


(1) During the day, to fly after that for at least 30 minutes; or

(2) At night, to fly after that for at least 45 minutes.

No person may operate a civil aircraft in IFR conditions unless it carries enough fuel (considering weather reports and forecasts and weather conditions) to—

(1) Complete the flight to the first airport of intended landing;

(2) Except as provided in paragraph (b) of this section, fly from that airport to the alternate airport; and

(3) Fly after that for 45 minutes at normal cruising speed or, for helicopters, fly after that for 30 minutes at normal cruising speed.

3.4.3.5.4

No person may begin a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed—

(1) During the day, to fly after that for at least 30 minutes; or

(2) At night, to fly after that for at least 45 minutes.

No person may operate a civil aircraft in IFR conditions unless it carries enough fuel (considering weather reports and forecasts and weather conditions) to—

3.4.3.6.1

For general aviation operations, the pilot is the operator as noted in the definition for operator in Annex 6, Part II and is not required to develop policies or procedures.

Chapter 3.11

Manuals, logs and records

3.11.2.3

The FAA considers the terms Maintenance Program and Inspection Program to be different. In addition, the FAA recognizes there are significant differences between an air carrier maintenance program and an inspection program used in non-air carrier operations. The FAA requires air carriers that operate certain types of aircraft to have a maintenance program (CAMP). In general, some non air-carrier aircraft, along with aircraft operated under 14 CFR part 91, are not required to have a maintenance program. However, FAA regulations and various Advisory Circulars allow the operator/registered owner to use a maintenance program if they decide to do so. 14 CFR § 91.409 identifies the inspection programs available for selection by a registered owner. Advisory Circular 120-16 may be used as a guide to develop a maintenance program.

Section III

International General Aviation

2.18

The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft.

2.6.3.2

The United States allows the continuation of an approach regardless of the reported weather.

5.2.1

The U.S. has no provision that visual landmarks used in VFR be located at least every 60 NM (110km).

ANNEX 7 - AIRCRAFT NATIONALITY AND REGISTRATION MARKS

4.3.1

The marks are not required on wing structure; only tail or fuselage.

4.3.2

14 CFR § 45.25(b)(2) allows the marks to be placed on engine pods or appurtenances if they are located between the trailing edge of the wing and the leading edge of the horizontal stabilizer and are an integral part of the fuselage side surfaces. Annex 7, §4.3.2 does not mention the ability to place markings on the engine pod or appurtenances.

5.2.2

United States regulations use inches rather than centimeters. 14 CFR § 45.29 prescribes minimum heights of marks as 12 inches generally for fixed-wing aircraft, except marks may be 2 inches in some grandfathered cases, and 3 inches on a glider and for certain experimental certificates. Marks must be at least 3 inches high for airships, spherical balloons, nonspherical balloons, powered parachutes and weight-shift-control aircraft. Marks must be at least 12 inches high for rotorcraft except certain grandfathered rotorcraft.

The minimum height of marks on small (12,500 lb. or less), fixed-wing aircraft is 3 inches when none of the following exceeds 180 knots true airspeed: (1) design cruising speed; (2) maximum operating limit speed; (3) maximum structural cruising speed; and (4) if none of the foregoing speeds have been determined for the aircraft, the speed shown to be the maximum cruising speed of the aircraft.

10.1

The U.S. identification plate does not include the nationality or registration mark.

10.2

With respect to location of identification plate: for aircraft other than 14 CFR part 121, location must be either adjacent to and aft of the rear-most entrance door or on the fuselage near the tail surfaces.

a) There is no explicit U.S. registration requirement for unmanned free balloons and no requirement to carry an identification plate. A centralized registry of unmanned free balloons is not maintained. Operators are required to furnish the nearest ATC facility with a prelaunch notice containing information on the date, time, and location of release, and the type of balloon. This information is not maintained for any specified period of time.

b) With respect to RPA/small Unmanned Aircraft, in place of a “plate”, the FAA requires “markings" for the small UAS, which are not required to be fireproof. The FAA only allows markings on external surfaces.

ANNEX 8 - AIRWORTHINESS OF AIRCRAFT

PART II Procedures for Certification and Continued Airworthiness

Chapter 1

Type Certification

1.2.5

ICAO requires that the design of an aircraft under ICAO Annex 8, Parts IIIB, IVB, and V use alternative fire extinguishing agents to halon in the lavatories, engines, and auxiliary power units. The United States does not have a similar requirement.

PART III Large Aeroplanes

Part IIIA

Aeroplanes over 5 700 kg for which application for certification was submitted on or after 13 June 1960, but before 2 March 2004

Chapter 4

Design and Construction

4.1.6 (b), 4.1.6 (f), 4.1.6 (g), 4.1.6 (h), 4.1.6 (i)

The FAA does not have similar requirements relative to paragraphs b) and f). The FAA published a notice to amend the U.S. regulations with the purpose of eventually meeting the intent of these provisions for new designs. However, the amendment will not be retroactive and will apply to airplanes for which application for certification is submitted after the effective dates of the future amendment. For b), the FAA does not have a specific requirement for physical separation of systems. However, physical separation is considered in the means of compliance to various regulations such as 25.1309, 25.901(c) and 25.903(d). The FAA also does not have a requirement for continued safe flight and landing after ANY event resulting in damage to the airplane structure or systems.

For g), h) and i), the FAA does not have specific requirements to consider the effects of explosions or incendiary devices.

Chapter 8

Instruments and Equipment

8.4.1

ICAO requires that airplanes operating on the movement area of an airport shall have airplane lights of such intensity, color, fields of coverage and other characteristics to furnish personnel on the ground with as much time as possible for interpretation and for subsequent maneuver necessary to avoid a collision. The FAA has no such requirement.

8.4.2

This provision addresses the lights' effect on outside observers in reference to “harmful dazzle.” The U.S. regulations do not address the effect of aircraft lights on outside observers. However, visibility to other pilots and the lights' effect on the flight crew is addressed.

Chapter 9

Operating Limitations and Information

9.3.5

The United States does not have similar requirements. The FAA has begun work in an effort to amend the U.S. regulations with the purpose of eventually meeting the intent of these provisions.

Chapter 11

Security

11.2, 11.3, 11.4

With the exception of the door required by 11.3, the United States does not have similar requirements. The FAA has begun work in an effort to amend the U.S. regulations with the purpose of eventually meeting the intent of these provisions.

Part IIIB

Aeroplanes over 5 700 kg for which application for certification was submitted on or after 2 March 2004

Chapter 3

Structure

3.8.2

14 CFR 25.571 addresses structural durability. The damage-tolerance principles were introduced at amendment 25-45 of 14 CFR 25.571 (effective 12/1/1978), and therefore all applicable products/parts certified on or after 12/1/1978 are required to be damage-tolerant (except as provided by 14 CFR 21.101). It is noted that "Likely structural repairs" is not a consideration under 14 CFR 25.571, and therefore Section 3.8.2 appears to be different in this regard. However, as a post-type certification requirement, 14 CFR part 26 requires TC holders who develop published repair data to perform a damage tolerance evaluation of any repair that affects fatigue critical structure and incorporate any required damage tolerance-based inspections into the published repair data. In addition, the provisions for repairs reside in 14 CFR part 43, not part 21. All structural repairs are required to meet the certification basis of the airplane. 14 CFR 25.571 considers sonic fatigue whereas Section 3.8.1 of Annex 8 does not have a corresponding explicit requirement for sonic fatigue considerations. It is thus observed that 14 CFR 25.571 is more stringent in this regard. Lastly, amendment 25-132 of 14 CFR 25.571 (effective 1/14/2011) introduced the requirement for a Limit of Validity on the airframe of an airplane (on top of the requirement for considering WFD), and therefore 14 CFR is more stringent in this regard.

Chapter 4

Design and Construction

4.1.6

On November 28, 2008, the FAA adopted new regulations that meet the intent of these provisions. However, Part IIIB applies to airplanes with a date of application of March 2, 2004 or later, but the U.S. requirements apply to airplanes with a date of application of November 28, 2008 or later.

4.2 g)4)

The United States has not modified regulations to require manufacturers to include the elements of the aeroplane design associated with cargo compartment fire protection and a summary of the demonstrated standards that were considered in the process of aeroplane certification, in the documentation made available to the operator for those aircraft certificated on or after 1 January 2025.

D.2 (g)

Paragraph D.2.g.1 of the ICAO standard requires a fire suppression system for each cargo compartment accessible to a crewmember in a passenger-carrying airplane. U.S. requirements permit manual fire fighting in an accessible cargo compartment by a crewmember or members for an all-passenger-carrying airplane or a passenger-cargo combination carrying airplane.

 

Additionally, the FAA does not have specific requirements to consider the effects of explosions or incendiary devices.

D.2 (h)

The United States does have provisions to protect against possible instances of cabin depressurization. However, the FAA does not have specific requirements to consider the effects of explosions or incendiary devices.

F.4.1

ICAO requires that airplanes operating on the movement area of an airport shall have airplane lights of such intensity, color, fields of coverage and other characteristics to furnish personnel on the ground with as much time as possible for interpretation and for subsequent maneuver necessary to avoid a collision. The U.S. has no such requirement.

PART IV Helicopters

Part IVA

Helicopters for which application for certification was submitted on or after 22 March 1991 but before 13 December 2007

Chapter 2

Flight

2.2.3.1,

2.2.3.1.1 - 2.2.3.1.4

These provisions address take-off performance data for all classes of helicopters and require that this performance data include the take-off distance required. However, the United States has adopted the requirements only for Category A helicopters.

Chapter 6

Rotor and Power Transmissions Systems and Powerplant Installation

6.7

This provision requires that there be a means for restarting a helicopter's engine at altitudes up to a declared maximum altitude. In some cases the FAA does not require demonstration of engine restart capability. Since there is a different level of certitude for transport and normal category helicopters in the United States, the engine restart capability is only required for Category A and B helicopters (14 CFR Part 29) and Category A normal helicopters (14 CFR Part 27).

Chapter 7

Instruments and Equipment

7.4.2

This provision addresses the need to switch off or reduce the intensity of the flashing lights. The United States has minimum acceptable intensities that are prescribed for navigation lights and anti-collision lights. No reduction below these levels is possible.

7.4.2 (b)

 

This provision addresses the lights' effect on outside observers in reference to “harmful dazzle.” The U.S. regulations do not address the effect of aircraft lights on outside observers. However, visibility to other pilots and the lights' effect on the flight crew is addressed.

PART V Small Aeroplanes

Part VA

Aeroplanes over 750 kg but not exceeding 5 700 kg for which application for certification was submitted on or after 13 December 2007 but before 7 March 2021

Chapter 8

Crashworthiness and Cabin Safety

8.5 (e)

The FAA provides requirements for emergency lighting systems in 14CFR 23.812. These requirements do not address the impact of the fuel spillage on emergency lighting systems. Only commuter category airplanes are required to install emergency lighting systems.

2.5

The crew list is required by statute.

2.7

There is a statutory requirement for the Cargo Manifest.

2.8

In order to combat illicit drug smuggling, the U.S. requires the additional following information: the shipper's and the consignee's name and address, the type of air waybills, weight, and number of house air waybills. The manifest submitted in electronic form may become legally acceptable in the future. However, until the compliance rate for the automated manifest is acceptable, the U.S. must be able to require the written form of the manifest.

Remarks

19 CFR 122.48

2.9

Nature of goods information is required.

2.10

Stores list required in all cases but may be recorded on General Declaration in lieu of a separate list.

2.21

There is a statutory requirement that such changes can only be made prior to or at the time of formal entry of the aircraft.

2.25

The U.S. does not support the use of insecticides in aircraft with passengers present. Pesticides registered for such use should not be inhaled. In effect, the passenger safety issue has precluded the use of such insecticides in the presence of passengers since 1979.

2.35

Advance notice is required of the number of citizens and aliens on board (non-scheduled flights only).

2.40

A copy of the contract for remuneration or hire is required to be a part of the application in the case of non-common carrier operations.

2.41

Single inspection is accorded certain aircraft not by size of aircraft but rather by type of operation. Loads (cargo) of an agricultural nature require inspection by a plant or animal quarantine inspector.

2.11.3.2.2

 

Class E-5 700/1200-foot airspace areas are used for transitioning aircraft to/from the terminal or en route environment.

 

2.11.3.3

 

En Route Domestic Airspace Areas consist of Class E airspace that extends upward from a specified altitude to provide controlled airspace in those areas where there is a requirement to provide IFR en route ATC services but the Federal airway structure is inadequate. En Route Domestic Airspace Areas may be designated to serve en route operations when there is a requirement to provide ATC service but the desired routing does not qualify for airway designation. Offshore/Control Airspace Areas are locations designated in international airspace (between the U.S. 12-mile territorial limit and the CTA/FIR boundary, and within areas of domestic radio navigational signal or ATC radar coverage) wherein domestic ATC procedures may be used for separation purposes.

 

2.11.5.1

A Class D airspace area shall be of sufficient size to: 1. Allow for safe and efficient handling of operations. 2. Contain IFR arrival operations while between the surface and 1,000 feet above the surface, and IFR departure operations while between the surface and the base of adjacent controlled airspace. Size and shape may vary to provide for 1 and 2. The emphasis is that a Class D area shall be sized to contain the intended operations.

2.11.5.3

Refer to Surface Areas. The U.S. uses the term “Surface Area". Surface area is airspace contained by the lateral boundary of the Class B, C, D, or E airspace designated for an airport that begins at the surface and extends upward.

2.26.5

No time is issued prior to taxi for take-off. Time checks are given to the nearest quarter minute.

2.29

Process is described in the FAA Safety Management System Manual and the FAA Order 1100.161.

Chapter 3

Air Traffic Control Service

3.2

Air Route Traffic Control Facilities (ARTCC) are used instead of Area Control Service, and Terminal Control Facilities instead of Approach Control Service.

3.6.2.4

The U.S does not specify notification of 2-way communication. The accepting unit shall not alter the clearance of an aircraft that has not yet reached the transfer of control point without the prior approval of the transferring unit.

3.7.3.1

Air crews are not required to read back clearances, only to acknowledge receipt of clearances.

Certain air traffic controller safety-related parts of ATC clearances and instructions which are transmitted by voice and which must be read back according to US requirements.

“Ensure pilots acknowledge all Air Traffic Clearances and ATC Instructions. When a pilot reads back an Air Traffic Clearance or ATC Instruction:

Ensure that items read back are correct.

Ensure the read back of hold short instructions, whether a part of taxi instructions or a LAHSO clearance.

Ensure pilots use call signs and/or registration numbers in any read back acknowledging an Air Traffic Clearance or ATC Instruction.”

3.7.3.1.1

Air crews are not required to read back clearances, only to acknowledge receipt of clearances.

3.7.3.3

The U.S. only requires a read back for operations regarding hold short instructions. Controllers may request a read back whenever they feel a read back is necessary.

3.7.4.3

4-3-8. COORDINATION WITH RECEIVING FACILITY Coordinate with the receiving facility before the departure of an aircraft if the departure point is less than 15 minutes flying time from the transferring facility's boundary unless an automatic transfer of data between automated systems will occur, in which case the flying time requirement may be reduced to 5 minutes or replaced with a mileage from the boundary parameter when mutually agreeable to both facilities.

3.7.4.4

4-4-5. CLASS G AIRSPACE Include routes through Class G airspace only when requested by the pilot. NOTE-1. Flight plans filed for random RNAV routes through Class G airspace are considered a request by the pilot. 2. Flight plans containing MTR segments in/through Class G airspace are considered a request by the pilot. Air Traffic Control Clearance means an authorization by air traffic control within controlled airspace.

Chapter 4

Flight Information Service

4.2.2

No Class F airspace. Collision Hazard information is provided between known traffic to aircraft in Class G airspace.

Chapter 6

Air Traffic Services Requirements for Communications

6.1.1.4

6.2.2.3.8

The US uses a 45 day retention period.

6.2.3.6

The US has a 45 day or longer retention period, with some exceptions. US en route facilities using system analysis recording tapes as their radar retention media shall retain radar data for 15 days. Facilities using a teletype emulator or console printout must be retained for 30 days unless they are related to an accident or incident. A facility using a console typewriter printout take-up device may retain the printout on the spool for 15 days after the last date on the spool. If a request is received to retain data information following an accident or incident, the printout of the relative data will suffice and the tape/disc may then be returned to service through the normal established rotational program.

6.3.1.3

The US has a 45 day or longer retention period except that those facilities utilizing an analog voice recorder system shall retain voice recordings for 15 days.

6.4.1.2

The US retains surveillance data recordings for 45 days or longer when they are pertinent to an accident or incident investigation, except that en route facilities using system analysis recording tapes as their radar retention media (regardless of the type of voice recorder system being used) shall retain voice recordings for 15 days and those facilities using an analog voice recorder system shall retain voice recordings for 15 days. FAA's Air Traffic Control System Command Center shall retain voice recordings for 15 days.

Chapter 7

Air Traffic Services Requirements for Information

7.1.5

The term “communication station" is not used but the flight information is passed.

7.6

Temporary Flight Restrictions (TFRs) are the mechanism that would be implemented in such cases.

Appendix 2

Principles Governing the Establishment and Identification of Significant Points

3.1

In US, per FAA Order 8260.19D, there are some points not to be named. Fixes used for navigation not to be named include Visual Descent Points (VDPs), radar fixes used on ASR and/or PAR procedures, RNAV missed approach point at threshold, and an ATD fix located between the MAP and the landing area marking the visual segment descent point on COPTER RNAV PinS approach annotated “PROCEED VISUALLY."

Additionally, there are some non-pronounceable points allowed. Order 8260.19 states “Except as noted below, each name must consist of a 5-letter pronounceable word. These non-pronounceable exceptions include; Stepdown fixes between FAF and MAP, Missed Approach Points (MAP), Computer Navigation Fixes (CNFs), and VFR Waypoints.

Appendix 4

ATS Airspace Classifications

 

Speed restrictions of 250 knots do not apply to aircraft operating beyond 12 NM from the coast line within the U.S. Flight Information Region, in offshore Class E airspace below 10,000 feet MSL.

 

Paragraph (a) of § 91.117 of Title 14 of the Code of Federal Regulations (CFR) provides that “Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots.” Within domestic airspace, a pilot operating at or above 10,000 MSL on an assigned speed adjustment greater than 250 knots is expected to comply with § 91.117(a) when cleared below 10,000 feet MSL without notifying Air Traffic Control (ATC).

 

The Federal Aviation Administration has proceeded from an operational perspective that the speed restrictions of § 91.117(a) do not apply to U.S.-registered aircraft, via § 91.703(a)(3), when operating outside the United States (and not within another country's territorial airspace).

Appendix 6

Fatigue Risk Management System (FRMS) Requirements

1.2 f)

Breaks (“relief periods”) required to be “of reasonable duration” (Section 2-5-4c) and “administered in an equitable manner” (2-6-6a)y. Minimum duration not defined except for a meal break (30 minutes).

1.2 Note

Variation from prescriptive schedule rules must be entered into the Daily Record of Facility Operation at the time of the deviation.

3 b)

FAA does not have specific processes for deviations or variations from prescriptive fatigue management regulations.

ANNEX 12 - SEARCH AND RESCUE

There are no reportable differences between U.S. regulations and the Standards and Recommended Practices contained in this Annex.

 

ANNEX 13 - AIRCRAFT ACCIDENT INVESTIGATION

Chapter 5

Investigation

5.1.2

The U.S. is unable to investigate all serious incidents. A decision on whether to investigate a serious incident will consider factors such as the potential consequences of the incident, an assessment of available staff and resources, and the potential benefit to future safety.

5.12

The laws of the United States require the determination and public reporting of the facts, circumstances, and cause(s) or probable cause(s) of every civil aircraft accident. These laws, including the U.S. Freedom of Information Act, do not confine the disclosure of such information to an accident investigation or report. Accordingly, factual information such as statements, records of communications between persons, and air traffic recordings and transcripts are generally made public. United States law prohibits the public disclosure of cockpit voice recordings and visual recordings and limits the public disclosure of cockpit voice recording transcripts or written depictions of visual information to that information which is deemed relevant by the investigative authority. However, U.S. Courts can order the disclosure of the foregoing information for other than accident investigation purposes.

Regarding issues related to the competent authority, the U.S. approach is consistent with Annex 13 and ICAO Document 10053 in recognizing limits in a State's ability to protect investigation records that may be sought for other public purposes, including freedom of information laws. This approach is fully consistent with the balancing test that has been broadly applied in the U.S. in determining whether applicable laws and regulations require the public disclosure of these records or permit their withholding from the public.

5.12.2

The laws of the United States require the determination and public reporting of the facts, circumstances, and cause(s) or probable cause(s) of every civil aircraft accident. These laws, including the U.S. Freedom of Information Act, do not confine the disclosure of such information to an accident investigation or report. United States law prohibits the public disclosure of cockpit voice recordings and visual recordings and limits the public disclosure of cockpit voice recording transcripts or written depictions of visual information to that information which is deemed relevant by the investigative authority. However, U.S. Courts can order the disclosure of the foregoing information for other than accident investigation purposes.

5.12.3

The laws of the United States require the determination and public reporting of the facts, circumstances, and cause(s) or probable cause(s) of every civil aircraft accident. These laws, including the U.S. Freedom of Information Act, do not confine the disclosure of such information to an accident investigation or report.

United States law may afford protection of the names of persons involved in accidents or incidents in some cases, though not all cases. U.S. Courts can order the disclosure of the foregoing information. In addition, while it is U. S. practice not to identify names of such persons in accident and incident reports, those names may be revealed in background material made available to the public as required by U.S. law.

5.12.6

The United States supports the principle of not circulating, publishing, or providing access to a draft Report or any part thereof, or any documents obtained during the investigation, unless such a report or document has already been published or released by the State that conducted the investigation. However, the laws of the United States facilitate the public disclosure of information held by government agencies and commercial businesses. The U.S. government may not be able to restrict public access to a draft Report or any part thereof on behalf of the State conducting the investigation. However, regarding “Foreign Investigations”, neither the Board, nor any agency receiving information from the Board, shall release records pertaining to an investigation until the State conducting the investigation issues its Final Report or 2 years following the date of the accident, whichever occurs first. The standard for determining public access to information requested from a U.S. government agency or a commercial business does not consider or require the express consent of the State conducting an investigation.

5.19

The United States may find it necessary to accept a limited number of advisors appointed to assist the accredited representative and will exercise discretion in determining whether the skills and expertise of the advisor(s) are appropriate for the conduct of the aircraft accident or incident investigation.

5.20

The United States may find it necessary to accept a limited number of advisors appointed to assist the accredited representative and will exercise discretion in determining whether the skills and expertise of the advisor(s) are appropriate for the conduct of the aircraft accident or incident investigation.

5.25

Concerning 5.25(h), investigative procedures observed by the United States allow full participation in all progress and investigation planning meetings; however, deliberations related to analysis, findings, probable causes, and safety recommendations are restricted to the investigative authority and its staff. However, contributions to these areas are permitted through timely written submissions, as specified in paragraph 5.25(i).

5.25 h)

Investigative procedures observed by the U.S. allow full participation in all progress and investigation planning meetings; however, deliberations related to analysis, findings, probable causes, and safety recommendations are restricted to the investigative authority and its staff. However, participation in these areas is extended through timely written submissions, as specified in paragraph 5.25 i).

5.26

Concerning 5.26(b): The United States supports, in principle, the privacy of the State conducting the investigation regarding the progress and the findings of that investigation. However, the laws of the United States facilitate the public disclosure of information held by U.S. government agencies and U.S. commercial businesses. Notwithstanding any other provision of law, regarding “Foreign Investigations”, neither the Board, nor any agency receiving information from the Board, shall release records pertaining to an investigation until the State conducting the investigation issues its Final Report or 2 years following the date of the accident, whichever occurs first. The standard for determining public access to information requested from a U.S. government agency or a commercial business does not consider or require the express consent of the State conducting the investigation.

5.26 b)

The U.S. supports, in principle, the privacy of the State conducting the investigation regarding the progress and the findings of that investigation. However, the laws of the U.S. facilitate the public disclosure of information held by U.S. government agencies and U.S. commercial business. The standard for determining public access to information requested from a U.S. government agency or a commercial business does not consider or require the expressed consent of the State conducting the investigation.

Chapter 6

Reporting

6.2

The United States supports the principle of not circulating, publishing, or providing access to a draft Report or any part thereof, or any documents obtained during the investigation, unless such a report or document has already been published or released by the State that conducted the investigation. However, the laws of the United States facilitate the public disclosure of information held by government agencies and commercial businesses. The U.S. government may not be able to restrict public access to a draft Report or any part thereof on behalf of the State conducting the investigation. However, regarding “Foreign Investigations”, neither the Board, nor any agency receiving information from the Board, shall release records pertaining to an investigation until the State conducting the investigation issues its Final Report or 2 years following the date of the accident, whichever occurs first. The standard for determining public access to information requested from a U.S. government agency or a commercial business does not consider or require the express consent of the State conducting an investigation.

6.3

The United States requires that comments on draft final reports be received within 30 days of transmittal unless an extension is provided.

6.13

The U.S. supports the principle of not circulating, publishing, or providing access to a draft report or any part thereof unless such a report or document has already been published or released by the State which conducted the investigation. However, the laws of the U.S. facilitate the public disclosure of information held by government agencies and commercial business. The U.S. government may not be able to restrict public access to a draft report or any part thereof on behalf of the State conducting the investigation.

ANNEX 14 - AERODROMES

VOLUME 1 - AERODROME DESIGN AND OPERATIONS

Chapter 1

General

1.2.1

Airports in the U.S. are for the most part owned and operated by local governments and quasi-government organizations formed to operate transportation facilities. The Federal Government provides air traffic control, operates and maintains NAVAIDs, provides financial assistance for airport development, certificates major airports, and issues standards and guidance for airport planning, design, and operational safety.

There is general conformance with the Standards and Recommended Practices of Annex 14, Volume I. At airports with scheduled passenger service using aircraft having more than nine seats, compliance with standards is enforced through regulation and certification. At other airports, compliance is achieved through the agreements with individual airports under which Federal development funds were granted; or, through voluntary actions.

1.3.1
1.3.2
1.3.3
1.3.4

In the U.S., the Airport Reference Code is a two-component indicator relating the standards used in the airport's design to a combination of dimensional and operating characteristics of the largest aircraft expected to use the airport. The first element, Aircraft Approach Category, corresponds to the ICAO PANS-OPS approach speed groupings. The second, Airplane Design Group, corresponds to the wingspan groupings of code element 2 of the Annex 14, Aerodrome Reference Code. See below:

The airport reference point is recomputed when the ultimate planned development of the airport is changed.

2.9.6
2.9.7

Minimum friction values have not been established to indicate that runways are ``slippery when wet.'' However, U.S. guidance recommends that pavements be maintained to the same levels indicated in the ICAO Airport Services Manual.

2.11.3

If inoperative fire fighting apparatus cannot be replaced immediately, a NOTAM must be issued. If the apparatus is not restored to service within 48 hours, operations shall be limited to those compatible with the lower index corresponding to operative apparatus.

2.12 e)

Where the original VASI is still installed, the threshold crossing height is reported as the center of the on-course signal, not the top of the red signal from the downwind bar.

1The width of a precision (lower than 3/4 statute mile approach visibility minimums) runway is 23 meters for a runway which is to accommodate only small (less than 5,700 kg) airplanes and 30 meters for runways accommodating larger airplanes.

2For airplanes with a maximum certificated take-off mass greater than 68,000 kg, the standard runway width is 45 meters.

 

3.1.12

FAA allows dual and triple simultaneous independent approaches when runway centerlines are at least 3100 feet apart.

3.1.14*

Longitudinal runway slopes of up to 1.5 percent are permitted for aircraft approach categories C and D except for the first and last quarter of the runway where the maximum slope is 0.8 percent.

3.1.19*

Minimum and maximum transverse runway slopes are based on aircraft approach categories as follows:
For categories A and B: 1.0 - 2.0 percent
C and D: 1.0 - 1.5 percent

3.2.2

The U.S. does not require that the minimum combined runway and shoulder widths equal 60 meters. The widths of shoulders are determined independently.

3.2.3*

The transverse slope on the innermost portion of the shoulder can be as high as 5 percent.

3.3.3
3.3.4*
3.3.5*

A strip width of 120 meters is used for code 3 and 4 runways for precision, nonprecision, and non-instrumented operations. For code 1 and 2 precision runways, the width is 120 meters. For non-precision/visual runways, widths vary from 37.5 meters up to 120 meters.

3.3.9*

Airports used exclusively by small aircraft (U.S. Airplane Design Group I) may be graded to distances as little as 18 meters from the runway centerline.

3.3.14*

The maximum transverse slope of the graded portion of the strip can be 3 percent for aircraft approach categories C and D and 5 percent for aircraft approach categories A and B.

3.3.15*

The U.S. does not have standards for the maximum transverse grade on portions of the runway strip falling beyond the area that is normally graded.

3.3.17*

Runways designed for use by smaller aircraft under non-instrument conditions may be graded to distances as little as 18 meters from the runway centerline (U.S. Airplane Design Groups I and II).

3.4.2*

For certain code 1 runways, the runway end safety areas may be only 72 meters.

3.7.1*
3.7.2*

The U.S. does not provide Standards or Recommended Practices for radio altimeter operating areas.

3.8.3*

The U.S. specifies a 6 meter clearance for Design Group VI airplanes.

3.8.4*

The taxiway width for Design Group VI airplanes is 30 meters.

3.8.5*

The U.S. also permits designing taxiway turns and intersections using the judgmental oversteering method.

3.8.7*

Minimum separations between runway and taxiway centerlines, and minimum separations between taxiways and taxilanes and between taxiway/taxilanes and fixed/moveable objects are shown in the tables that follow. Generally, U.S. separations are larger for non-instrumented runways, and smaller for instrumented runways, than the Annex. Values are also provided for aircraft with wingspans up to 80 meters.

Chapter 4

Obstacle Restriction and Removal

4.1

Obstacle limitation surfaces similar to those described in 4.1-4.20 are found in 14 CFR Part 77.

4.1.21

A balked landing surface is not used.

4.1.25

The U.S. does not establish take-off climb obstacle limitation areas and surface, per se, but does specify protective surfaces for each end of the runway based on the type of approach procedures available or planned. The dimensions and slopes for these surfaces and areas are listed in the table above.

4.2

The dimensions and slopes of U.S. approach areas and surfaces are set forth in the above table. Aviation regulations do not prohibit construction of fixed objects above the surfaces described in these sections.

4.2.1

Primary surface is also used as a civil airport imaginary surface. Primary surface is a surface longitudinally centered on a runway.

U.S. uses the width of the primary surface of a runway as prescribed in 14 CFR Part 77.25 for the most precise approach existing or planned for either end of that runway.

4.2.8

The slope and dimensions of the approach surface applied to each end of a runway are determined by the most precise approach existing or planned for that runway end.

4.2.9

Approach surfaces are applied to each end of each runway based upon the type of approach available or planned for that runway end.

4.2.10,
4.2.11

Any proposed construction of or alteration to an existing structure is normally considered to be physically shielded by one or more existing permanent structure(s), natural terrain, or topographic feature(s) of equal or greater height if the structure under consideration is located within the lateral dimensions of any runway approach surface but would not exceed an overall height above the established airport elevation greater than that of the outer extremity of the approach surface, and located within, but would not penetrate, the shadow plane(s) of the shielding structure(s).

4.2.12

The basic principle in applying shielding guidelines is whether the location and height of the structures are such that aircraft, when operating with due regard for the shielding structure, would not collide with that structure.

4.2.16

The size of each imaginary surface is based on the category of each runway according to the type of approach available or planned for that runway. The slope and dimensions of the approach surface applied to each end of a runway are determined by the most precise approach existing or planned for that runway end.

4.2.17

Approach surfaces are applied to each end of each runway based upon the type of approach available or planned for that runway end.

Chapter 5

Visual Aids for Navigation

5.2.1.7*

The U.S. does not require unpaved taxiways to be marked.

5.2.2.2*

The U.S. does not require a runway designator marking for unpaved runways.

5.2.2.4

Zeros are not used to precede single-digit runway markings. An optional configuration of the numeral 1 is available to designate a runway 1 and to prevent confusion with the runway centerline.

5.2.4.2* 5.2.4.3*

Threshold markings are not required, but sometimes provided, for non-instrument runways that do not serve international operations.

5.2.4.5

The current U.S. standard for threshold designation is eight stripes, except that more than eight stripes may be used on runways wider than 45 meters. After 1 January 2008, the U.S. standard will comply with Annex 14.

5.2.4.6

The width and spacing of threshold stripes will comply with Annex 14 after 1 January 2008.

5.2.4.10

When a threshold is temporarily displaced, there is no requirement that runway or taxiway edge markings, prior to the displaced threshold, be obscured. These markings are removed only if the area is unsuitable for the movement of aircraft.

5.2.5.2
5.2.5.3*

Aiming point markings are required on precision instrument runways and code 3 and 4 runways used by jet aircraft.

5.2.5.4

The aiming point marking commences 306 meters from the threshold at all runways.

5.2.6.3

The U.S. pattern for touchdown zone markings, when installed on both runway ends, is only applicable to runways longer than 4,990 feet. On shorter runways, the three pair of markings closest to the runway midpoint are eliminated.

5.2.6.4

The U.S. standard places the aiming point marking 306 meters from the threshold where it replaces one of the pair of three stripe threshold markings. The 306 meters location is used regardless of runway length.

5.2.6.5*

Touchdown zone markings are not required at a non-precision approach runway, though they may be provided.

5.2.7.4*

Runway side stripe markings on a non-instrument runway may have an over-all width of 0.3 meter.

5.2.8.3

Taxiway centerline markings are never installed longitudinally on a runway even if the runway is part of a standard taxi route.

5.2.9.5*

The term ``ILS'' is used instead of CAT I, CAT II, CAT III.

5.2.11.4 5.2.11.5* 5.2.11.6*

Check-point markings are provided, but the circle is 3 meters in diameter, and the directional line may be of varying width and length. The color is the yellow used for taxiway markings.

5.2.12

Standards for aircraft stand markings are not provided.

5.2.13.1*

Apron safety lines are not required although many airports have installed them.

5.2.14.1

The U.S. does not have standards for holding position markings on roadways that cross runways. Local traffic control practices are used.

5.3.1.1 5.3.1.2*

The U.S. does not have regulations to prevent the establishment of non-aviation ground lights that might interfere with airport operations.

5.3.1.3
5.3.1.4

New approach lighting installations will meet the frangibility requirements. Some existing non-frangible systems may not be replaced before 1 January 2005.

5.3.2.1* 5.3.2.2* 5.3.2.3*

There is no requirement for an airport to have emergency runway lighting available if it does not have a secondary power source. Some airports do have these systems, and there is an FAA specification for these lights.

5.3.3.1
5.3.3.3

Only airports served by aircraft having more than 30 seats are required to have a beacon, though they are available at many others.

5.3.3.6

Although the present U.S. standard for beacons calls for 24-30 flashes per minute, some older beacons may have flash rates as low as 12 flashes per minute.

5.3.3.8

Coded identification beacons are not required and are not commonly installed. Typically, airport beacons conforming to 5.3.3.6 are installed at locations served by aircraft having more than 30 seats.

5.3.4.1

While the U.S. has installed an approach light system conforming to the specifications in 5.3.4.10 through 5.3.4.19, it also provides for a lower cost system consisting of medium intensity approach lighting and sequenced flashing lights (MALSF) at some locations.

5.3.4.2

In addition to the system described in 5.3.4.1, a system consisting of omnidirectional strobe lights (ODALS) located at 90 meters intervals extending out to 450 meters from the runway threshold is used at some locations.

5.3.4.10
through
5.3.4.19

The U.S. standard for a precision approach category I lighting system is a medium intensity approach lighting system with runway alignment indicator lights (MALSR). This system consists of 3 meters barrettes at 60 meters intervals out to 420 meters from the threshold and sequenced flashing lights at 60 meters intervals from 480 meters to 900 meters. A crossbar 20 meters in length is provided 300 meters from the threshold. The total length of this system is dependent upon the ILS glide path angle. For angles 2.75° and higher, the length is 720 meters.

5.3.4.16
5.3.4.31

The capacitor discharge lights can be switched on or off when the steady-burning lights of the approach lighting system are operating. However, they cannot be operated when the other lights are not in operation.

5.3.4.20

The U.S. standard for a precision approach category II and III lighting system has a total length dependent upon the ILS glide path angle. For angles 2.75° and higher, the length is 720 meters.

5.3.5.1
5.3.5.3
5.3.5.4

Visual approach slope indicator systems are not required for all runways used by turbojets except runways involved with land and hold short operations that do not have an electronic glideslope system.

5.3.5.2

In addition to PAPI and APAPI systems, VASI and AVASI type systems remain in service at U.S. airports with commercial service. Smaller general aviation airports may have various other approach slope indicators including tri-color and pulsating visual approach slope indicators.

5.3.5.27

The U.S. standard for PAPI allows for the distance between the edge of the runway and the first light unit to be reduced to 9 meters for code 1 runways used by nonjet aircraft.

5.3.5.42

The PAPI obstacle protection surface used is as follows: The surface begins 90 meters in front of the PAPI system (toward the threshold) and proceeds outward into the approach zone at an angle 1 degree less than the aiming angle of the third light unit from the runway. The surface flares 10 degrees on either side of the extended runway centerline and extends 4 statute miles from its point of origin.

5.3.8.4

The U.S. permits the use of omnidirectional runway threshold identification lights.

5.3.13.2

The U.S. does not require the lateral spacing of touchdown zone lights to be equal to that of touchdown zone marking when runways are less that 45 meters wide.

The lateral distance between the markings is 22 meters when installed on runways with a width of 45 meters or greater. The distance is proportionately smaller for narrower runways. The lateral distance between touchdown zone lights is nominally 22 meters but may be reduced to 20 meters to avoid construction problems.

5.3.14

The U.S. has no provision for stopway lights.

5.3.15.1
5.3.15.2*

Taxiway centerline lights are required only below 183 meters RVR on designated taxi routes. However, they are generally recommended whenever a taxiing problem exists.

5.3.15.3
8.2.3

Taxiway centerline lights are not provided on runways forming part of a standard taxi route even for low visibility operations. Under these conditions, the taxi path is coincident with the runway centerline, and the runway lights are illuminated.

5.3.15.5

Taxiway centerline lights on exit taxiways presently are green. However, the new U.S. standard which is scheduled to be published by 1 January 98 will comply with the alternating green/yellow standard of Annex 14.

5.3.15.7*

The U.S. permits an offset of up to 60 cm.

5.3.16.2
8.2.3

Taxiway edge lights are not provided on runways forming part of a standard taxi route.

5.3.17.4*
5.3.17.5*

Stop bars are required only for runway visual range conditions less than a value of 183 meters at taxiway/runway intersections where the taxiway is lighted during low visibility operations. Once installed, controlled stop bars are operated at RVR conditions less than a value of 350 meters.

5.3.17.6

Elevated stop bar lights are normally installed longitudinally in line with taxiway edge lights. Where edge lights are not installed, the stop bar lights are installed not more than 3 meters from the taxiway edge.

5.3.17.9

The beamspread of elevated stop bar lights differs from the inpavement lights. The inner isocandela curve for the elevated lights is ± 7 horizontal and ± 4 vertical.

5.3.17.12

The U.S. standard for stop bars, which are switchable in groups, does not require the taxiway centerline lights beyond the stop bars to be extinguished when the stop bars are illuminated. The taxiway centerline lights which extend beyond selectively switchable stop bars are grouped into two segments of approximately 45 meters each. A sensor at the end of the first segment re-illuminates the stop bar and extinguishes the first segment of centerline lights. A sensor at the end of the second segment extinguishes that segment of centerline lights.

5.3.18.1*

Taxiway intersection lights are also used at other hold locations on taxiways such as low visibility holding points.

5.3.18.2

Taxiway intersection lights are collocated with the taxiway intersection marking. The marking is located at the following distances from the centerline of the intersecting taxiway:

U.S. practice uses the NO ENTRY sign to prohibit entry by aircraft only.

5.4.2.8
5.4.2.10

The second mandatory instruction sign is usually not installed unless added guidance is necessary.

5.4.2.15

Signs for holding aircraft and vehicles from entering areas where they would infringe on obstacle limitation surfaces or interfere with NAVAIDs are inscribed with the designator of the approach, followed by the letters ``APCH''; for example, ``15-APCH.''

5.4.3.13
5.4.3.15

U.S. practice is to install signs about 3 to 5 meters closer to the taxiway/runway (See Annex 14, Table 5-4).

5.4.3.16

The U.S. does not have standards for the location of runway exit signs.

5.4.3.24

A yellow border is used on all location signs, regardless of whether they are stand-alone or collocated with other signs.

Chapter 6

Visual Aids for Denoting Obstacles

6.1

Recommended practices for marking and lighting obstacles are found in FAA Advisory Circular 70/7460-1J, Obstruction Marking and Lighting.

6.1.3

Any temporary or permanent structure, including all appurtenances, that exceeds an overall height of 200 feet (61m) above ground level or exceeds any obstruction standard contained in 14 CFR Part 77, should normally be marked and/or lighted.

6.2.1

This chapter provides recommended guidelines to make certain structures conspicuous to pilots during daylight hours. One way of achieving this conspicuity is by painting and/or marking these structures.

Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

6.2.3*

The maximum dimension of the rectangles in a checkered pattern is 6 meters on a side.

6.2.7

Markers should be displayed in conspicuous positions on or adjacent to the structure so as to retain the general definition of the structure. They should be recognizable in clear air from a distance of at least 4,000 feet (1219m) and in all directions from which aircraft are likely to approach. Markers should be distinctively shaped, i.e., spherical or cylindrical, so they are not mistaken for items that are used to convey other information. They should be replaced when faded or otherwise deteriorated.

6.2.11

Flag markers should be displayed around, on top, or along the highest edge of the obstruction. When flags are used to mark extensive or closely grouped obstructions, they should be displayed approximately 50 feet (15m) apart. The flag stakes should be of such strength and height that they will support the flags above all surrounding ground, structures, and/or objects of natural growth.

6.2.12

Each side of the flag marker should be at least 2 feet (0.6m) in length.

Standard does not specifically address mobile objects.

6.2.14

Color patterns. Flags should be colored as follows: solid, orange and white, and checkerboard. Standard does not specifically address mobile objects.

6.3.1

Obstruction lighting may be displayed on structures as follows: aviation red obstruction lights; medium intensity flashing white obstruction lights, high intensity flashing white obstruction lights, dual lighting, obstruction lights during construction, obstruction lights in urban areas, and temporary construction equipment lighting.

6.3.11

The height of the structure AGL determines the number of light levels.

Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

6.3.13

When a structure lighted by a high intensity flashing light system is topped with an antenna or similar appurtenance exceeding 40 feet (12m) in height, a medium intensity flashing white light (L-865) should be placed within 40 feet (12m) from the tip of the appurtenance. This light should operate 24 hours a day and flash simultaneously with the rest of the lighting system.

6.3.14

The number of light units recommended depends on the diameter of the structure at the top.

6.3.16

Lights should be installed on the highest point at each end. At intermediate levels, lights should be displayed for each 150 feet (46m) or fraction thereof. The vertical position of these lights should be equidistant between the top lights and the ground level as the shape and type of obstruction will permit. One such light should be displayed at each outside corner on each level with the remaining lights evenly spaced between the corner lights.

6.3.17

Lights should be installed on the highest point at each end. At intermediate levels, lights should be displayed for each 150 feet (46m) or fraction thereof. The vertical position of these lights should be equidistant between the top lights and the ground level as the shape and type of obstruction will permit. One such light should be displayed at each outside corner on each level with the remaining lights evenly spaced between the corner lights.

6.3.18

Lights should be installed on the highest point at each end. At intermediate levels, lights should be displayed for each 150 feet (46m) or fraction thereof. The vertical position of these lights should be equidistant between the top lights and the ground level as the shape and type of obstruction will permit. One such light should be displayed at each outside corner on each level with the remaining lights evenly spaced between the corner lights.

6.3.19,
6.3.20

One or more light units is needed to obtain the desired horizontal coverage. The number of light units recommended per level (except for the supporting structures of catenary wires and buildings) depends upon the average outside diameter of the specific structure, and the horizontal beam width of the light fixture. The light units should be installed in a manner to ensure an unobstructed view of the system by a pilot approaching from any direction. The number of lights recommended is the minimum.

The U.S. does not utilize Type A or Type B obstacle lights. Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

6.3.21*
6.3.22*

The effective intensity, for daylight-luminance background, of Type A high-intensity obstacle lights is 270,000 cd ± 25 percent.
The effective intensity, for daylight-luminance background, of Type B high-intensity obstacle lights is 140,000 cd ± 25 percent.

6.3.22

The height of the structure AGL determines the number of light levels. The light levels may be adjusted slightly, but not to exceed 10 feet (3m) when necessary to accommodate guy wires and personnel who replace or repair light fixtures. If an adjacent object shields any light, horizontal placement of the lights should be adjusted or additional lights should be mounted on that object to retain or contribute to the definition of the obstruction.

Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

6.3.23,
6.3.24,
6.3.27,
6.3.29

Red obstruction lights are used to increase conspicuity during nighttime. The red obstruction lighting system is composed of flashing omnidirectional beacons (L-864) and/or steady burning (L-810) lights. When one or more levels is comprised of flashing beacon lighting, the lights should flash simultaneously.

The U.S. does not utilize Type A, B, C, or D obstacle lights. Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in

6.3.28

When objects within a group of obstructions are approximately the same overall height above the surface and are located a maximum of 150 feet (46m) apart, the group of obstructions may be considered an extensive obstruction. Install light units on the same horizontal plane at the highest portion or edge of prominent obstructions. Light units should be placed to ensure that the light is visible to a pilot approaching from any direction.

6.3.30,
6.3.31,
6.3.32

The medium intensity flashing white light system is normally composed of flashing omni- directional lights. Medium intensity flashing white obstruction lights may be used during daytime and twilight with automatically selected reduced intensity for nighttime operation.

The U.S. does not utilize Type A, B, or C obstacle lights. Medium intensity flashing white (L-865) obstruction lights may provide conspicuity both day and night. Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of structures and overall layout of design.

6.3.35

Use high intensity flashing white obstruction lights during daytime with automatically selected reduced intensities for twilight and nighttime operations. When high intensity white lights are operated 24 hours a day, other methods of marking and lighting may be omitted.

The U.S. does not utilize Type A obstacle lights. Lighting with high intensity (L-856) flashing white obstruction lights provides the highest degree of conspicuity both day and night. Recommendations on marking structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

Chapter 7

Visual Aids for Denoting Restricted Use Areas

7.1.2*

A ``closed'' marking is not used with partially closed runways. See 5.2.4.10, above.

7.1.4

Crosses with shapes similar to figure 7.1, illustration b) are used to indicate closed runways and taxiways.
The cross for denoting a closed runway is yellow.

7.1.5

In the U.S. when a runway is permanently closed, only the threshold marking, runway designation marking, and touchdown zone marking need be obliterated. Permanently closed taxiways need not have the markings obliterated.

7.1.7

The U.S. does not require unserviceability lights across the entrance to a closed runway or taxiway when it is intersected by a night-use runway or taxiway.

7.4.4

Flashing yellow lights are used as unserviceability lights. The intensity is such as to be adequate to delineate a hazardous area.

Chapter 8

Equipment and Installations

8.1.5*
8.1.6*
8.1.7
8.1.8

A secondary power supply for non-precision instrument and non-instrument approach runways is not required, nor is it required for all precision approach runways.

The U.S. does not provide secondary power specifically for take-off operations below 550 meters RVR.

8.2.1

There is no requirement in the U.S. to interleave lights as described in the Aerodrome Design Manual, Part 5.

8.2.3

See 5.3.15.3 and 5.3.16.2

8.7.2*
8.7.3
8.7.4*

Glide slope facilities and certain other installations located within the runway strip, or which penetrate obstacle limitation surfaces, may not be frangibly mounted.

8.9.7*

A surface movement surveillance system is recommended for operations from 350 meters RVR down to 183 meters. Below 183 meters RVR, a surface movement radar or alternative technology is generally required.

Chapter 9

Emergency and Other Services

9.1.1

Emergency plans such as those specified in this section are required only at airports serving scheduled air carriers using aircraft having more than 30 seats. These airports are certificated under 14 CFR Part 139. In practice, other airports also prepare emergency plans.

9.1.12

Full-scale airport emergency exercises are conducted at intervals, not to exceed three years, at airports with scheduled passenger service using aircraft with more than 30 seats.

9.2.1

Rescue and fire fighting equipment and services such as those specified in this section are required only at airports serving scheduled air carriers in aircraft having more than 30 seats. Such airports generally equate to ICAO categories 4 through 9.
Other airports have varying degrees of services and equipment.

9.2.3*

There is no plan to eliminate, after 1 January 2005, the current practice of permitting a reduction of one category in the index when the largest aircraft has fewer than an average of five scheduled departures a day.

9.2.4
9.2.5

The level of protection at U.S. airports is derived from the length of the largest aircraft serving the airport similar to the Annex's procedure, except that maximum fuselage width is not used.
U.S. indices A-E are close equivalents of the Annex's categories 5-9. The U.S. does not have an equivalent to category 10.

The required firefighting equipment and agents by index are shown in the table above.

The substitution equivalencies between complementary agents and foam meeting performance level A are also used for protein and fluoroprotein foam. Equivalencies for foam meeting performance level B are used only for aqueous film forming foams.

9.2.18*

There is no specific requirement to provide rescue equipment as distinguished from firefighting equipment.

9.2.19*

At least one apparatus must arrive and apply foam within 3 minutes with all other required vehicles arriving within 4 minutes.

Response time is measured from the alarm at the equipment's customary assigned post to the commencement of the application of foam at the mid-point of the farthest runway.

9.2.29*

For ICAO category 6 (U.S. index B), the U.S. allows one vehicle.

9.4.4

At the present time, there is no requirement to perform tests using a continuous friction measuring device with self-wetting features. Some U.S. airports own these devices, while others use less formal methods to monitor build-up of rubber deposits and the deterioration of friction characteristics.

9.4.15

The standard grade for temporary ramps is 15 feet longitudinal per 1 inch of height (0.56 percent slope) maximum, regardless of overlay depth.

9.4.19

There is no U.S. standard for declaring a light unserviceable if it is out of alignment or if its intensity is less than 50 percent of its specified value.

ANNEX 14 - AERODROMES

VOLUME II - HELIPORTS

Chapter 1

Definitions

Declared distances

The U.S. does not use declared distances (take-off distance available, rejected take-off distance available, or landing distance available) in designing heliports.

Final approach and take-off area (FATO)

The U.S. ``take-off and landing area'' is comparable to the ICAO FATO, and the U.S. ``FATO'' is more comparable to the ICAO TLOF. The U.S. definition for the FATO stops with ``the take-off manoeuvre is commenced.'' This difference in definition reflects a variation in concept. The rejected take-off distance is an operational computation and is not required as part of the design.

Helicopter stand

The U.S. does not use the term “helicopter stand.” Instead, the U.S. considers paved or unpaved aprons, helipads, and helidecks, all as helicopter parking areas; i.e., helicopter stands.

Safety area

The U.S. considers the safety area to be part of the take-off and landing area which surrounds the FATO and does not call for or define a separate safety area.

Touchdown and lift-off area (TLOF)

The U.S. differs in the definition by considering helipads and helidecks to be FATO. The U.S. does not define the load bearing area on which the helicopter may touch down or lift-off as a TLOF.

Chapter 2

Heliport Data

2.1 d)

The U.S. does not measure or report a safety area as a separate feature of a heliport.

2.2

The U.S. does not ``declare'' distances for heliports.

Chapter 3

Physical Characteristics

3.1.2

The U.S. does not distinguish between single-engine and multi-engine helicopters for the purposes of heliport design standards. Neither does the U.S. design or classify heliports on the basis of helicopter performance. The U.S. FATO dimensions are at least equal to the rotor diameter of the design single rotor helicopter and the area must be capable of providing ground effect. The U.S. does not have alternative design standards for water FATOs, elevated heliports, or helidecks.

3.1.3

The U.S. has a single gradient standard; i.e., 5 percent, except in fueling areas where the limit is 2 percent, which is applicable for all portions of heliports.

3.1.6
3.1.7*
3.1.8*

The U.S. does not require or provide criteria for clearways in its design standards. It does encourage ownership and clearing of the land underlying the innermost portion of the approach out to where the approach surface is 10.5 meters above the level of the take-off surface.

3.1.14 to 3.1.21

Safety areas are considered part of the take-off and landing area (or primary surface) in U.S. heliport design. The take-off and landing area of the U.S. design criteria, based on 2 rotor diameters, provides for the ICAO safety area; however, the surface does not have to be continuous with the FATO or be load bearing.

3.1.22

Taxiway widths are twice the undercarriage width of the design helicopter.

3.1.23

The U.S. requires 1.25 rotor diameters plus 2 meters of separation between helicopter ground taxiways.

3.1.24

The U.S. gradient standard for taxiways is a maximum of 5 percent.

3.1.32*

The U.S. sets no gradient standards for air taxiways.

3.1.33

Chapter 4

Obstacle Restriction and Removal

4.1.1

The U.S. approach surface starts at the edge of the take-off and landing area.

4.1.2 a)

The U.S. approach surface width adjacent to the heliport take-off and landing area is a minimum of 2 rotor diameters.

4.1.2 b) 2)

The U.S. precision instrument approach surface flares from a width of 2 rotor diameters to a width of 1,800 meters at the 7,500 meters outer end. The U.S. does not use a note similar to the one that follows 4.1.4, as it does not differentiate between helicopter requirements on the basis of operational performance.

4.1.5

The outer limit of the U.S. transitional surfaces adjacent to the take-off and landing area is 76 meters from the centerline of the VFR approach/departure surfaces. The transitional surface width decreases to zero at a point 1,220 meters from the take-off and landing area. It does not terminate at an inner horizontal surface or at a predetermined height.

4.1.6

The U.S. transitional surfaces have a fixed width, 76 meters less the width of the take-off and landing area, from the approach centerline for visual operations and an outwardly flaring width to 450 meters for precision instrument operations. The U.S. does not use an inner horizontal surface nor terminate the transitional surfaces at a fixed/predetermined height.

4.1.7 b)

Since the U.S. includes the safety area in the take-off and landing area, the comparable elevation is at the elevation of the FATO.

4.1.9 through 4.1.20

The U.S. does not use the inner horizontal surface, the conical surface, or take-off climb surface described in these paragraphs or the note following paragraph 4.1.20 for heliport design.

4.1.21 through 4.1.25

The U.S. does not have alternative criteria for floating or fixed-in-place helidecks.

4.2

The U.S. has no requirement for a note similar to the one following the heading ``Obstacle limitation requirements.''

4.2.1

The U.S. criteria does not require a take-off climb surface or a conical obstacle limitation surface to establish a precision instrument approach procedure.

4.2.2

The U.S. criteria does not require a take-off climb surface or a conical obstacle limitation surface to establish a non-precision instrument approach procedure.

4.2.3

The U.S. criteria does not require a take-off climb obstacle limitation surface to establish a non-instrument approach procedure.

4.2.4*

The U.S. has no requirement for protective surfaces such as an inner horizontal surface or a conical surface.

4.2.5

The U.S. does not have tables for heliport design comparable to the ICAO Tables 4-1 to 4-4.

4.2.6

The U.S. subscribes to the intent of this paragraph to limit object heights in the heliport protective surfaces but uses fewer surfaces with different dimensions for those surfaces.

4.2.7*

The U.S. subscribes to the intent of this paragraph but uses different dimensional surfaces.

4.2.8

The U.S. criterion requires that a heliport have at least one approach and departure route and encourages multiple approaches separated by arcs of 90 to 180 degrees.

4.2.9*

The U.S. has no requirement that a heliport's approach surfaces provide 95 percent usability.

4.2.10

Since the U.S. does not differentiate between surface level and elevated heliports, the comments to paragraphs 4.2.1 through 4.2.5 above apply.

4.2.11

The U.S. has no requirement for a take-off climb surface. It does require at least one approach/departure surface and encourages that there be as many approaches as is practical separated by arcs of 90 to 180 degrees.

4.2.12 through 4.2.22

Since the U.S. does not have alternative design criteria for helidecks or shipboard heliports, there are no comparable U.S. protective surface requirements.

Tables 4-1, 4-2, 4-3, 4-4

The U.S. does not have tables comparable to the ICAO Tables 4-1 to 4-4.

Chapter 5

The U.S. criteria is not specific on the light intensity of the flash.

5.3.3.3

The U.S. criterion specifies a 300 meters approach light system configuration. The light bars are spaced at 30 meters intervals. The first two bars of the configuration are single lights, the next two bars are two lights, then two bars with three lights, then two bars with four lights, and finally two bars with five lights.

ANNEX 16 - ENVIRONMENTAL PROTECTION

VOLUME I - AIRCRAFT NOISE

Reference: Part 36 of Title 14 of the United States Code of Federal Regulations

Chapter 1

 

1.7

Each person who applies for a type certificate for an airplane covered by 14 CFR Part 36, irrespective of the date of application for the type certificate, must show compliance with Part 36.

Chapter 2

 

2.1.1

For type design change applications made after 14 August 1989, if an airplane is a Stage 3 airplane prior to a change in type design, it must remain a Stage 3 airplane after the change in type design regardless of whether Stage 3 compliance was required before the change in type design.

2.3.1 a)

Sideline noise is measured along a line 450 meters from and parallel to the extended runway centerline for two- and three-engine aircraft; for four-engine aircraft, the sideline distance is 0.35 NM.

2.4.2

Noise level limits for Stage 2 derivative aircraft depend upon whether the engine by-pass ratio is less than two. If it is, the Stage 2 limits apply. Otherwise, the limits are the Stage 3 limits plus 3 dB or the Stage 2 value, whichever is lower.

2.4.2.2 b)

Take-off noise limits for three-engine, Stage 2 derivative airplanes with a by-pass ratio equal to or greater than 2 are 107 EPNdB for maximum weights of 385,000 kg (850,000 lb) or more, reduced by 4 dB per halving of the weight down to 92 EPNdB for maximum weights of 28,700 kg (63,177 lb) or less. Aircraft with a by-pass ratio less than 2 only need meet the Stage 2 limits.

2.5.1

Trade-off sum of excesses not greater than 3 EPNdB and no excess greater than 2 EPNdB.

2.6.1.1

For airplanes that do not have turbo-jet engines with a by-pass ratio of 2 or more, the following apply:
a) four-engine airplanes - 214 meters (700 feet);
b) all other airplanes - 305 meters (1,000 feet).
For all airplanes that have turbo-jet engines with a by-pass ratio of 2 or more, the following apply:
a) four-engine airplanes - 210 meters (689 feet);
b) three-engine airplanes - 260 meters (853 feet);
c) airplanes with fewer than three engines - 305 meters (1,000 feet).
The power may not be reduced below that which will provide level flight for an engine inoperative or that will maintain a climb gradient of at least 4 percent, whichever is greater.

Chapter 3

 

3.1.1

For type design change applications made after 14 August 1989, if an airplane is a Stage 3 airplane prior to a change in type design, it must remain a Stage 3 airplane after the change in type design regardless of whether Stage 3 compliance was required before the change in type design.

3.3.1 a) 2)

The U.S. has no equivalent provision in 14 CFR Part 36.

3.3.2.2

A minimum of two microphones symmetrically positioned about the test flight track must be used to define the maximum sideline noise. This maximum noise may be assumed to occur where the aircraft reaches 305 meters (1,000 feet).

 

14 CFR Part 36 does not require symmetrical measurements to be made at each and every point for propeller-driven airplane sideline noise determination.

3.6.2.1 c)

Under 14 CFR Part 36, during each test take-off, simultaneous measurements should be made at the sideline noise measuring stations on each side of the runway and also at the take-off noise measuring station. If test site conditions make it impractical to simultaneously measure take-off and sideline noise, and if each of the other sideline measurement requirements is met, independent measurements may be made of the sideline noise under simulated flight path techniques. If the reference flight path includes a power cutback before the maximum possible sideline noise level is developed, the reduced sideline noise level, which is the maximum value developed by the simulated flight path technique, must be the certificated sideline noise value.

3.6.2.1 d)

14 CFR Part 36 specifies the day speeds and the acoustic reference speed to be the minimum approved value of V2 +10 kt, or the all-engines operating speed at 35 feet (for turbine-engine powered airplanes) or 50 feet (for reciprocating-engine powered airplanes), whichever speed is greater as determined under the regulations constituting the type certification basis of the airplane. The test must be conducted at the test day speeds ±3 kt.

3.7.4

If a take-off test series is conducted at weights other than the maximum take-off weight for which noise certification is requested:
a) at least one take-off test must be at or above that maximum weight;
b) each take-off test weight must be within +5 or -10 percent of the maximum weight.
If an approach test series is conducted at weights other than the maximum landing weight for which certification is requested:
a) at least one approach test must be conducted at or above that maximum weight;
b) each test weight must exceed 90 percent of the maximum landing weight.
Total EPNL adjustment for variations in approach flight path from the reference flight path and for any difference between test engine thrust or power and reference engine thrust or power must not exceed 2 EPNdB.

Chapter 5

 

5.1.1

Applies to all large transport category aircraft (as they do to all subsonic turbo-jet aircraft regardless of category). Commuter category aircraft, propeller-driven airplanes below 8,640 kg (19,000 lb) are subject to 14 CFR Part 36, Appendix F or to Appendix G, depending upon the date of completion of the noise certification tests.

Chapter 6

 

6.1.1

Applies to new, all propeller-driven airplane types below 19,000 lb (8,640 kg.) in the normal, commuter, utility, acrobatic, transport, or restricted categories for which the noise certification tests are completed before 22 December 1988.

Chapter 8

 

General

14 CFR Part 36 (Section 36.1 (h)) defines Stage 1 and Stage 2 noise levels and Stage 1 and Stage 2 helicopters. These definitions parallel those used in 14 CFR Part 36 for turbo-jets and are used primarily to simplify the acoustical change provisions in Section 36.11.

 

14 CFR Part 36 (Section 36.805(c)) provides for certain derived versions of helicopters for which there are no civil prototypes to be certificated above the noise level limits.

8.1.1 a)

Applicable to new helicopter types for which application for an original type certificate was made on or after 6 March 1988.

8.1.1 b)

Applicable only to “acoustical changes'' for which application for an amended or supplemental type certificate was made on or after 6 March 1988.

8.4

14 CFR Part 36 Appendix H specifies a slightly different rate of allowable maximum noise levels as a function of helicopter mass. The difference can lead to a difference in the calculated maximum noise limits of 0.1 EPNdB under certain roundoff condition.

8.6.3.1 b)

Does not include the VNE speeds.

8.7

14 CFR Part 36 Appendix H does not permit certain negative corrections. Annex 16 has no equivalent provision.

8.7.4

EPNL correction must be less than 2.0 EPNdB for any combination of lateral deviation, height, approach angle and, in the case of flyover, thrust or power.

 

Corrections to the measured data are required if the tests were conducted below the reference weight.

 

Corrections to the measured data are required if the tests were conducted at other than reference engine power.

8.7.5

The rotor speed must be maintained within one percent of the normal operating RPM during the take-off procedure.

8.7.8

The helicopter shall fly within ±10° from the zenith for approach and take-off, but within ±5° from the zenith for horizontal flyover.

Chapter 10

 

General

Exception from acoustical change rule given for aircraft with flight time prior to 1 January 1955 and land configured aircraft reconfigured with floats or skis.

10.1.1

Applies to new, amended, or supplemental type certificates for propeller-driven airplanes not exceeding 8,640 kg (19,000 lb) for which noise certification tests have not been completed before 22 December 1988.

10.4

The maximum noise level is a constant 73 dBA up to 600 kg (1,320 lb). Above that weight, the limit increases at the rate of 1 dBA/75kg (1 dBA/165 lb) up to 85 dBA at 1,500 kg (3,300 lb) after which it is constant up to and including 8,640 kg (19,000 lb).

10.5.2, second phase, d)

For variable-pitch propellers, the definition of engine power is different in the second segment of the reference path. Maximum continuous installed power instead of maximum power is used.

Chapter 11

 

11.1

14 CFR Part 36 Appendix J was effective 11 September 1992 and applies to those helicopters for which application for a type certificate was made on or after 6 March 1986.

11.4

14 CFR Part 36 Appendix J specifies a slightly different rate of allowable maximum noise levels as a function of helicopter mass. The difference can lead to a difference in the calculated maximum noise limits of 0.1 EPNdB under certain roundoff condition.

11.6

14 CFR Part 36 Appendix J prescribes a ±15 meter limitation on the allowed vertical deviation about the reference flight path. Annex 16 has no equivalent provision.

PART V

 

General

No comparable provision exists in U.S. Federal Regulations. Any local airport proprietor may propose noise abatement operating procedures to the FAA which reviews them for safety and appropriateness.

Appendix 1

 

General

Sections 3, 8, and 9 of Appendix 1 which contain the technical specifications for equipment, measurement and analysis and data correction for Chapter 2 aircraft and their derivatives differ in many important aspects from the corresponding requirements in Appendix 2 which has been updated several times. 14 CFR Part 36 updates have generally paralleled those of Appendix 2 of Annex 16. These updated requirements are applicable in the U.S. to both Stage 2 and Stage 3 aircraft and their derivatives.

2.2.1

A minimum of two microphones symmetrically positioned about the test flight track must be used to define the maximum sideline noise. This maximum noise may be assumed to occur where the aircraft reaches 305 meters (1,000 feet), except for four-engine, Stage 2 aircraft for which 439 meters (1,440 feet) may be used.

2.2.2

No obstructions in the cone defined by the axis normal to the ground and the half-angle 80° from the axis.

2.2.3 c)

Relative humidity and ambient temperature over the sound path between the aircraft and 10 meters above the ground at the noise measuring site is such that the sound attenuation in the 8 kHz one-third octave band is not greater than 12 dB/100 meters and the relative humidity is between 20 and 95 percent. However, if the dew point and dry bulb temperature used for obtaining relative humidity are measured with a device which is accurate to within one-half a degree Celsius, the sound attenuation rate shall not exceed 14 dB/100 meters in the 8 kHz one-third octave band.

2.2.3 d)

Test site average wind not above 12 kt and average cross-wind component not above 7 kt.

2.3.4

The aircraft position along the flight path is related to the recorded noise 10 dB downpoints.

2.3.5

At least one take-off test must be a maximum take-off weight and the test weight must be within +5 or -10 percent of maximum certificated take-off weight.

Appendix 2

 

2.2.1

A minimum of two symmetrically placed microphones must be used to define the maximum sideline noise at the point where the aircraft reaches 305 meters.

2.2.2

When a multiple layering calculation is required, the atmosphere between the airplane and the ground shall be divided into layers. These layers are not required to be of equal depth, and the maximum layer depth must be 100 meters.

2.2.2 b)

14 CFR Part 36 specifies that the lower limit of the temperature test window is 36 degrees Fahrenheit (2.2 degrees Celsius). Annex 16 provides 10 degrees Celsius as the lower limit for the temperature test window.

 

14 CFR Part 36 does not specify that the airport facility used to obtain meteorological condition measurements be within 2,000 meters of the measurement site.

2.2.2 c)

14 CFR Part 36 imposes a limit of 14 dB/100 meters in the 8 kHz one-third octave band when the temperature and dew point are measured with a device which is accurate to within one-half a degree Celsius.

2.2.3

14 CFR Part 36 requires that the limitations on the temperature and relative humidity test window must apply over the whole noise propagation path between a point 10 meters above the ground and the helicopter. Annex 16 specifies that the limitations on the temperature and relative humidity test window apply only at a point 10 meters above the ground.

 

14 CFR Part 36 requires that corrections for sound attenuation must be based on the average of temperature and relative humidity readings at 10 meters and the helicopter. Annex 16 implies that the corrections for sound absorption are based on the temperature and relative humidity measured at 10 meters only.

3.2.6

No equivalent requirement.

3.4.5

For each detector/integrator the response to a sudden onset or interruption of a constant sinusoidal signal at the respective one-third octave band center frequency must be measured at sampling times 0.5, 1.0, 1.5, and 2.0 seconds after the onset or interruption. The rising responses must be the following amounts before the steady-state level:
0.5 seconds: 4.0 ± 1.0 dB
1.0 seconds: 1.75 ± 0.75 dB
1.5 seconds: 1.0 ± 0.5 dB
2.0 seconds: 0.6 ± 0.5 dB

3.4.5 (Note 1)

No equivalent provision in 14 CFR Part 36.

3.5.2

No equivalent requirement.

5.4

14 CFR Part 36 requires that the difference between airspeed and groundspeed shall not exceed 10 kt between the 10 dB down time period.

8.4.2

14 CFR Part 36 specifies a value of -10 in the adjustment for duration correction. Annex 16 specifies a value of -7.5.

9.1.2, 9.1.3

14 CFR Part 36 always requires use of the integrated procedure if the corrected take-off or approach noise level is within 1.0 dB of the applicable noise limit.

Appendix 6

 

4.4.1

The microphone performance, not its dimensions, is specified. The microphone must be mounted 1.2 meters (4 feet) above ground level. A windscreen must be employed when the wind speed is in excess of 9 km/h (5 kt).

5.2.2 a)

Reference conditions are different. Noise data outside the applicable range must be corrected to 77 degrees F and 70 percent humidity.

5.2.2 c)

There is no equivalent provision in 14 CFR Part 36. Fixed-pitch propeller-driven airplanes have a special provision. If the propeller is fixed-pitch and the test power is not within 5 percent of reference power, a helical tip Mach number correction is required.
