Section 4. Services
10-4-1. AUTOMATIC
TERMINAL INFORMATION SERVICE (ATIS)
a. ATIS provides advance noncontrol airport/terminal
area and meteorological information for use by aircraft
arriving and departing and operating within the terminal
area. This can be accomplished by data link text,
available upon request, and/or a voice message recording,
which is a repetitive broadcast on a voice outlet.
b. Assign ATIS responsibilities to a specific position
of operation. These must include updating ATIS messages
and disseminating current messages to pertinent positions
of operation.
c. Before transmitting, the voice and/or text message
must be reviewed to ensure content is complete and
accurate. When appropriate, the voice/text must be
cross-checked to ensure the message content is the same.
In a conventional, controllerprepared voice
recording, the specialist must ensure:
1. The speech rate is not excessive,
2. The enunciation is of the highest quality, and
3. Each part of the message is easily understood.
d. Those facilities with runway construction must
ensure ATIS message content is complete, accurate, and
contains the proper information related to runway closures
and available length (feet). When runway construction is
underway, the review of the message should be made by a
person other than the specialist who prepared the
original, preferably either a supervisor or CIC.

e. Specific sequential portions of the alphabet may be
assigned between facilities or for an arrival and
departure ATIS when confusion could result from using the
entire alphabet for each ATIS.
1. A LOA must be established between facilities
designating the ATIS codes which will be used by each
facility.
2. A facility directive must be developed designating
the ATIS alphabet codes which will be used by each
facility or for an arrival and departure ATIS.
REFERENCE-
FAAO JO 7110.65, Para 2-9-1, Application.
EXAMPLE-
Departure ATIS codes could be assigned codes of “Alfa”
through “Mike” and arrival ATIS codes assigned “November”
through “Zulu.” The ATIS codes may also be divided between
facilities.
f. Make ATIS messages a matter of record on facility
recorders. If not possible, retain a written record of
each message in the facility's files for 15 days.
g. Keep messages as brief and as concise as possible.
Optimum duration of up to 30 seconds should not be
exceeded unless required for message content completeness.
h. During the hours of operation, part-time towers
that have ATIS capabilities and ASOS/AWOS ground to air
broadcast capability, must ensure that the latest METAR/SPECI
weather sequence is broadcast only on ATIS. ASOS/AWOS must
not be allowed to broadcast weather concurrent with ATIS.
i. During the hours of nonoperation, part-time towers
that have ATIS capabilities should record for continuous
broadcast the following information:
NOTE-
Those facilities that have ASOS/AWOS broadcast capability
must allow the automated weather report to be
broadcast on the ASOS/AWOS frequency in the one minute
update mode and include the applicable information
in subparas 10-4-1h, 1 thru 5 at the time of closing.
1. The local tower hours of operation.
2. ASOS/AWOS frequency.
3. The appropriate common traffic advisory frequency (CTAF).
4. The frequency for operating radio controlled
approach lights.
5. The FAA facility and frequency for additional
information.
EXAMPLE-
(Name of tower) tower hours of operation are (time) local
time to (time) local time. The frequency for automated
weather is (frequency). The common traffic advisory
frequency is (frequency). Pilot operated approach lighting
is available on (frequency). For additional information
contact (name of approach control or center) on
(frequency).
10-4-2. PRETAXI CLEARANCE PROCEDURES
a. If a need exists, facilities should develop pretaxi
clearance procedures for departing IFR aircraft. Use of CD
frequency is desirable for implementing such procedures.
However, facilities without CD frequency may use GC
frequency for pretaxi clearance if the service can be
provided without derogating the primary function of GC.
When developing pretaxi clearance procedures, do the
following:
1. Coordinate the proposed procedures with the airport
users.
2. Inform System Safety and Procedures, when
procedures are implemented.
b. Include the following in pretaxi procedures:
1. The procedures are not mandatory.
2. The pilot calls CD or GC not more than 10 minutes
before proposed taxi time.
3. The IFR clearance or the delay information should
be issued at the time of initial callup.
4. When the IFR clearance is issued on CD frequency,
the aircraft is changed to GC for taxi clearance.
5. Normally, the pilot need not inform GC of having
received IFR clearance on CD frequency. Some high activity
towers with unique operating position arrangements or
operating conditions may require the pilot to inform GC of
a portion of his/her routing or that he/she has received
his/her IFR clearance.
10-4-3. GATE HOLD PROCEDURES
a. The objective of gate hold procedures is to
restrict departure delays to 15 minutes or less after
engine start and taxi time. Facility air traffic managers
must ensure gate hold procedures and departure delay
information are made available to all pilots prior to
engine startup. Implement gate hold procedures when
departure delays exceed or are expected to exceed 15
minutes.
b. Facility air traffic managers must meet with
airport management and users to develop local gate hold
procedures at airports that have identified the need and
where air traffic operations dictate. Gate hold
procedures, when required, will be developed in accordance
with limitations imposed by local conditions. Include the
following general provisions in the procedures when
gatehold procedures are established.
1. Pilots must contact GC/CD prior to starting engines
to receive start time or taxi time, as appropriate. The
sequence for departure must be maintained in accordance
with the initial callup unless modified by flow control
restrictions.
2. Develop notification procedures for aircraft unable
to transmit without engine(s) running.
NOTE-
Inability to contact GC/CD prior to engine start must not
be justification to alter the departure sequence.
3. The operator has the final authority to decide
whether to absorb the delay at the gate, have the aircraft
towed to another area, or taxi to a delay absorbing area.
4. GC/CD frequency is to be monitored by the pilot. A
new proposed engine start time or taxi time must be issued
if the delay changes.
10-4-4. ADVISORY SERVICE TO ARRIVING VFR FLIGHTS
When it is desirable to reduce the workload at the LC
position, procedures should be established whereby
arriving aircraft make their first contact with the
control tower on the approach control frequency,
regardless of weather, provided the following conditions
exist:
a. Approach control and LC positions use separate
frequencies.
b. ATC service to IFR flights is not affected.
c. Use of the procedure will not hinder the operation
of VFR aircraft by requiring excessive routing or spacing.
d. Consideration is given to establishing radio
contact points based on time or distance rather than on
landmarks with which some pilots may not be familiar.
e. Where possible, radio contact
points and the routes between them and the airport are
different from those used by IFR flights.
f. Pilot participation is encouraged rather than
required, and compliance with the procedures is not made
mandatory.
10-4-5. PRACTICE INSTRUMENT APPROACHES
a. VFR aircraft practicing instrument approaches at
the approach control's primary airport must be provided
IFR separation in accordance with FAAO JO 7110.65, Air
Traffic Control, Chapter 4, Section 8, Approach Clearance
Procedures.
NOTE-
The primary airport is the airport from which approach
control service is provided, except for remoted facilities
where the facility air traffic manager will designate the
primary report.
b. IFR separation to VFR aircraft in accordance with
FAAO JO 7110.65, Chapter 4, Section 8, Approach Clearance
Procedures, must be provided to all secondary airports
under the approach control's jurisdiction to the extent
possible within existing resources. Where separation
service is provided to an airport with a FSS that provides
LAA, or a nonapproach control tower, provisions for
handling such aircraft must be included in a LOA.
c. Where standard separation is not provided to VFR
aircraft conducting practice approaches, instruct the
aircraft to maintain VFR and provide traffic information.
d. At airports where the tower does not provide
approach control service, handle practice instrument
approaches in accordance with a LOA between the tower and
the facility providing approach control service.
e. Facilities must issue a letter to airmen advising
the users of those airports where standard separation is
provided for VFR aircraft conducting practice instrument
approaches. The letter should specify which facility will
handle the aircraft practicing instrument approaches and
include the appropriate frequencies.
REFERENCE-
Para 4-5-2, Letters to Airmen.
10-4-6. SIMULTANEOUS
INDEPENDENT
APPROACHES
a. Independent
approaches may be conducted when:
1. Dual
parallel runway centerlines are at least 4,300 feet
apart.
2. Triple
parallel centerlines are at least 5,000 feet apart and
the airport field elevation is
less than 1,000 feet MSL.
b. Specially-designed
instrument approach procedures annotated with
“simultaneous approaches authorized with Rwy XX" are
authorized for simultaneous independent approaches.
c. Equipment
required to maintain communication, navigation, and
surveillance systems is operational with the glide slope
exception as noted below.
d. During
glide slope outages, facilities may continue to conduct
simultaneous independent approaches without vertical
guidance for a period of no more than 29 days, provided
the following requirements are identified in an Air
Traffic Safety Oversight Service (AOV) approved
contingency plan. At a minimum, the following special
provisions, conditions, and limitations must be
identified in the plan, if applicable, along with any
other facility-specific requirements:
1. An
LOA with the ATCT (or facility directive for a combined
facility) must contain a description of the procedures,
requirements, and any limitations as specified in the
facility contingency plan for glide slope out of service
procedures.
2. The
ATC facility must notify Technical Operations personnel
of the glide slope outage.
REFERENCE-
FAAO JO 7210.3, Para 3-5-2, System Component
Malfunctions
3. The
ATC facility must notify arriving pilots that the glide
slope is out of service. This can be accomplished via
the ATIS broadcast.
4. Any
other requirements specified in the local facility
contingency plan for glide slope out procedures must be
complied with before conducting simultaneous independent
approach procedures.
5. Controllers
must be trained and provided annual refresher training
concerning the application of these procedures.
6. The
ATC facility must record when the glide slope outage
occurs and any adverse impact on the operation on FAA
Form 7230-4, Daily Record of Facility Operation.
7. Any
loss of separation or break out associated with
operations under a contingency plan for glide slope out
must be reported to the Director, Terminal Operations,
Headquarters.
8. The
facility must have radar coverage down to the decision
altitude or minimum descent altitude, as applicable.
9. Approaches
must be terminated to the runway without a glide slope
whenever the reported visibility is below the
straight-in localizer minimum for that runway.
10. Any
required equipment for the approach with the glide slope
out of service must be operational, such as DME or
VORTAC.
e. Simultaneous
approaches with the glide slope unusable must be
discontinued after 29 days unless a waiver has been
submitted to and approved by FAA HQ. (See Appendix 4.)
f. When
simultaneous approaches are being conducted, the pilot
is expected to inform approach control, prior to
departing an outer fix, if the aircraft does not have
the appropriate airborne equipment or they do not choose
to conduct a simultaneous approach. Provide individual
handling to such aircraft.
10-4-7. SIMULTANEOUS
INDEPENDENT CLOSE PARALLEL APPROACHES – HIGH UPDATE
RADAR NOT REQUIRED
TERMINAL
a. Simultaneous close parallel approaches may
only be conducted where instrument approach charts
specifically authorize simultaneous approaches to
parallel runways.
b. Apply the following minimum separation when
conducting simultaneous independent close parallel
approaches:
1. Provide a minimum of 1,000 feet vertical or
a minimum of 3 miles radar separation between
aircraft during turnon to parallel final approach
courses.
NOTE-
Communications transfer to the tower controller's
frequency will be completed prior to losing vertical
separation between aircraft.
2. Parallel runway centerlines are separated by
a minimum of 3,600 feet or more, and the airport
elevation is less than 2,000' MSL.
3. Provide the minimum applicable radar
separation between aircraft on the same final
approach course.
REFERENCE-
FAAO JO 7110.65, Para 554, Minima
c. A highresolution color monitor with alert
algorithms, such as the final monitor aid, must be
used to monitor close parallel approaches.
d. In addition to subparagraphs a through c above,
facility ATMs must ensure that operational personnel
comply with the procedures specified in FAA Order
JO 7110.65, paragraph 599d through 599f.
REFERENCE-
FAA O JO 7110.65, Para 599, Simultaneous Independent Close
Parallel Approaches – High Update Radar Not Required
e. Facility managers must verify that adequate
radar coverage exists to safely perform simultaneous
approach operations to closely space runways.
10-4-8.
Simultaneous widely-spacEd parallel operations
The
concept for conducting simultaneous independent approaches
to widelyspaced parallel runways without final monitors
is:
a. Speciallydesigned instrument approach procedures
annotated with “Simultaneous Approaches Authorized with
Rwy XX” are authorized for simultaneous independent
approaches to widely spaced parallel runways.
1. A separate approach system is required for each
parallel runway. A minimum distance of more than 9,000
feet between centerlines is required when dual approaches
are used at field elevations at or below 5,000 feet MSL,
or 9,200 feet between runway centerlines is required with
a field elevation above 5,000 feet MSL. Other integral
parts of the total Simultaneous Approach System include
radar, communications, ATC procedures, and appropriate
airborne equipment.
2. When simultaneous approaches are being conducted,
the pilot is expected to inform approach control prior to
departing an outer fix if the aircraft does not have the
appropriate airborne equipment or they do not choose to
conduct a simultaneous approach. Provide individual
handling to such aircraft.
3. Closely monitor weather activity that could impact
the final approach course. Weather conditions in the
vicinity of either final approach course may dictate a
change of the approach in use. (See subpara 1016b Note,
Selecting Active Runways).
4. All turnons and final approaches are monitored by
radar. Since the primary responsibility for navigation
rests with the pilot, instructions from the controller are
limited to those necessary to ensure separation between
aircraft. Information and instructions are issued as
necessary to contain the aircraft on the final approach
course. Aircraft which are observed deviating from the
assigned final approach course are instructed to alter
course left or right, as appropriate, to return to the
desired course. Unless altitude separation is assured
between aircraft, immediate action must be taken by the
controller monitoring the adjacent parallel approach
course to require the aircraft in potential conflict to
alter its flight path to avoid the deviating aircraft.
5. Missed approach procedures
are established with climbs on diverging courses. To
reduce the possibility of error, the missed approach
procedure for a single runway operation should be revised,
as necessary, to be identical with that of a simultaneous
approach operation.
b. The following minimum radar and communications
equipment must be provided for monitoring simultaneous
approaches:
1. One separate airport surveillance radar display of
a model currently certified for ATC functions.
2. Establish separate radar and local control
positions for each final approach course.
3. Facility directives must define the position
responsible for providing the minimum applicable
longitudinal separation between aircraft on the same final
approach course.
c. Record the time the operation begins and ends on
the facility log.
d. Where possible, establish standard breakout
procedures for each simultaneous operation. If traffic
patterns and airspace permit, the standard breakout
altitude should be the same as the missed approach
altitude.
e. If there is an aircraft deviation requiring the
utilization of breakout procedures, or if there is a loss
of separation, specifically a compression on final error,
forward a copy of that QAR to the Terminal Procedures
Group via email at 9ATOTHQSafetyRiskManagement. This
requirement must be written into each facility SOP.
10-4-9. SIMULTANEOUS
CONVERGING INSTRUMENT APPROACHES
a. The
procedures to conduct Simultaneous Converging Instrument
Approaches (SCIA) must be developed in accordance with
the following paragraphs.
1. The ATM must:
(a) Determine
that the volume and complexity of aircraft operations
requires the use of simultaneous converging instrument
approaches. Additionally, no adverse impact on the users
or air traffic control facilities can result from the
implementation of the procedure.
(b) Coordinate with airport
operations to ensure that runway intersection
identification markings are in accordance with
appropriate standards if the runways intersect.
(c) Coordinate with the
responsible Service Area Flight Procedures Team (FPT)
through the service area Operations Support Group (OSG)
for the feasibility of SCIA procedural design and the
ability to achieve minimums sufficient to justify
procedural development. The FPT must consider all
aspects of the approach, including NAVAIDS, approach
lighting, and airport lighting.
(d) Prepare a staff study which
includes:
(1) Type of aircraft and user
groups that will be involved in SCIA operations.
(2) Anticipated effect on
airport/ airspace capacity, including projected
reductions in departure delays, airport acceptance rate
and projected savings in aircraft fuel consumption.
(3) Daily time periods during
which the procedure would be applied.
(4) A preliminary environmental
assessment in accordance with FAA Order 1050.1,
Environmental Impacts: Policies and Procedures (See
paragraph 4-1-6, Preliminary Environmental Review).
2. After completing steps 1
through 4 above, the ATM must:
(a) Submit the request for SCIA
operations, to include the completed staff study and a
draft graphic of the ILS-Standard Instrument Approach
Procedure, to their OSG for review.
(1) The OSG must coordinate the
procedure with the regional Flight Standards Division.
(2) When approved, the OSG will
process the package through the FPT for development.
(b) Develop a Letter to Airmen
defining local procedures to be used at least 30 days
before the effective date. Additional means of
publicizing local procedures must be employed in
accordance with paragraph 4-2-4, Coordination of ATC
Procedures.
b. The requirements for
conducting SCIA operations to converging runways are:
1. Operational air traffic
control radar.
2. Precision instrument approach
procedures must be established on each runway.
3. Non intersecting final
approach courses.
4. SIAP specifically titled
"Converging" and is published in parenthesis after the
title of the procedure, for example, ILS V Rwy 17
(Converging).
(a) Missed approach points (MAP)
must be at least 3 nautical miles (NM) apart, and
(b) Published missed approach
procedures diverge by at least 45 degrees.
(c) The ATM must designate a
primary and secondary runway for SCIA runway
configurations including separation responsibility and
procedures to be applied in the event a missed approach
is initiated inside the MAP.
(d) Flight Procedures will
determine the appropriate approach minimums for both
primary and secondary runways for each SCIA
configuration.
5. Converging approaches must not
be conducted simultaneously to runways that intersect,
when the ceiling is less than 1,000 feet or the
visibility is less than 3 miles.
6. Converging approaches to
runways that do not intersect may be conducted when the
ceiling is less than 1,000 feet or visibility less than
3 miles provided all other conditions of this directive
are met.
7. Application of this procedure
to intersecting runways does not relieve the controller
of the responsibility to provide intersecting runways
separation as required in FAA Order JO 7110.65,
paragraph 3-10-4.
8. A facility directive or letter
of agreement must be developed specifying as a minimum:
(a) The runway configurations to
be used during SCIA operations,
(b) Separation responsibility and
procedures, to be applied, in the event a missed
approach is initiated inside the MAP,
(c) Coordination requirements,
(d) Weather minima applicable to
each configuration, if different from published minima.
NOTE-
The ATM may establish higher minima than published
on the SIAP to preclude, to the extent feasible, the
possibility of a weather related missed approach.
c. Authorize simultaneous
instrument approaches to converging runways under the
following conditions:
1. Only straight-in approaches
must be made.
2. All appropriate communication,
navigation, and surveillance systems are operating
normally.
3. Aircraft must be informed on
initial contact, or as soon as possible, that
simultaneous converging approaches are in use.
Broadcasting this information on the ATIS satisfies this
requirement.
4. Weather activity that could
impact the final approach courses must be closely
monitored. Discontinue SCIA operations if weather trends
indicate deteriorating conditions which would make a
missed approach likely.
d. Record any occurrence of
simultaneous missed approaches while conducting SCIA on
FAA Form 7230-4, Daily Record of Facility Operation and
submit a mandatory occurrence report (MOR).
10-4-10.
PRECISION RUNWAY MONITOR-SIMULTANEOUS OFFSET
INSTRUMENT APPROACHES
a. Precision Runway Monitor-Simultaneous Offset
Instrument Approaches (PRM-SOIA) may be conducted at
airports with dual parallel runways with centerlines
separated by at least 750 feet and less than 3,000 feet,
with one straight-in Instrument Landing System (ILS)/Microwave
Landing System (MLS) and one Localizer Directional Aid (LDA),
offset by 2.5 to 3.0 degrees using a PRM system with a 1.0
second radar update system in accordance with the
provisions of an authorization issued by the Director of
Terminal Safety and Operations Support in coordination
with AFS. A high-resolution color monitor with alert
algorithms, such as a final monitor aid (FMA) must be
required.
b. Notification procedures for pilots unable to
accept an ILS PRM or LDA PRM approach clearance
can be found on the Attention All Users Page
(AAUP) of the Standard Instrument Approach
Procedures (SIAP) for the specific airport PRM
approach.
c. Closely monitor weather activity that could impact
the final approach course. Weather conditions in the
vicinity of either final approach course may dictate a
change of the approach in use. (See para 10-1-6, Selecting
Active Runways, subpara b Note.)
d. All turn-ons and final approaches are monitored by
radar. Since the primary responsibility for navigation
rests with the pilot, instructions from the controller are
limited to those necessary to ensure separation between
aircraft and to prevent aircraft from penetrating the NTZ.
Information and instructions are issued, as necessary, to
contain the aircraft's flight path within the Normal
Operating Zone (NOZ). Aircraft which are observed
approaching the No Transgression Zone (NTZ) are instructed
to alter course left or right, as appropriate, to return
to the desired course. Unless altitude separation is
assured between aircraft, immediate action must be taken
by the controller monitoring the adjacent parallel
approach course to require the aircraft in potential
conflict to alter its flight path to avoid the deviating
aircraft.
e. Missed approach procedures are established with
climbs on diverging courses. To reduce the possibility of
error, the missed approach procedure for a single runway
operation should be revised, as necessary, to be identical
with that of the PRM-SOIA operation.
f. Where possible, establish standard breakout
procedures for each simultaneous operation. If traffic
patterns and airspace permit, the standard breakout
altitude should be the same as the missed approach
altitude.
g. The following requirements
must be met for conducting PRM-SOIA:
1. All PRM, FMA, ILS, LDA with glideslope, distance
measuring equipment, and communications frequencies must
be fully operational.
2. The common NOZ and NTZ lines between the final
approach course centerlines must be depicted on the radar
video map. The NTZ must be 2,000 feet wide and centered an
equal distance from the final approach centerlines. The
remaining spaces between the final approach courses are
the NOZs associated with each course.
3. Establish monitor positions for each final approach
course that have override transmit and receive capability
on the appropriate control tower frequencies. A check of
the override capability at each monitor position must be
completed before monitoring begins. Monitor displays must
be located in such proximity to permit direct verbal
coordination between monitor controllers. A single display
may be used for two monitor positions.
4. Facility directives must define the position
responsible for providing the minimum applicable
longitudinal separation between aircraft on the same final
approach course.
h. Dual local control positions, while not mandatory,
are desirable.
i. Where possible, establish standard breakout
procedures for each simultaneous operation. If traffic
patterns and airspace permit, the standard breakout
altitude should be the same as the missed approach
altitude.
j. Wake turbulence requirements between aircraft on
adjacent final approach courses inside the LDA MAP are as
follows (standard in-trail wake separation must be applied
between aircraft on the same approach course):
1. When runways are at least 2,500 feet apart, there
are no wake turbulence requirements between aircraft on
adjacent final approach courses.
2. For runways less than 2,500 feet apart, whenever
the ceiling is greater than or equal to 500 feet above the
MVA, wake vortex spacing between aircraft on adjacent
final approach courses need not be applied.
3. For runways less than 2,500 feet apart, whenever
the ceiling is less than 500 feet above the MVA, wake
vortex spacing between aircraft on adjacent final approach
courses as described in FAAO JO 7110.65, Air Traffic
Control, para 5-5-4, Minima, must be applied unless
acceptable mitigating techniques and operational
procedures are approved by the Director of Terminal Safety
and Operations Support pursuant to an AFS safety
assessment. A request for a safety assessment must be
submitted to the Terminal Safety and Operations Support
Office through the service area office manager. The wake
turbulence mitigation techniques employed will be based on
each airport's specific runway geometry and meteorological
conditions and implemented through local facility
directives.
4. All applicable wake turbulence advisories must be
issued.
k. A local implementation team must be established at
each facility conducting PRM-SOIA. The team should be
comprised of representatives from the local airport
sponsor and other aviation organizations. The team will
monitor local operational integrity issues and
report/refer issues for national consideration as
appropriate.
l. For any new proposal to conduct PRM-SOIA, an
operational need must be identified by the ATC facility
manager, validated by the service area office manager, and
forwarded to the Terminal Safety and Operations Support
Office for appropriate action. The statement of
operational need should identify any required site
specific procedures.
10-4-11. REDUCED SEPARATION ON FINAL
Separation between aircraft may be reduced to 2.5 NM
in-trail separation on the final approach course within 10
NM of the runway provided an average Runway Occupancy Time
(ROT) of 50 seconds or less is documented for each runway.
ROT is the length of time required for an arriving
aircraft to proceed from over the runway threshold to a
point clear of the runway. The average ROT is calculated
by using the average of the ROT of no less than 250
arrivals. The 250 arrivals need not be consecutive but
must contain a representative sample of the types of
aircraft that use the runway. Average ROT documentation
must be revalidated within 30 days if there is a
significant change in runway/taxiway configuration, fleet
mix, or other factors that may increase ROT. Revalidation
need not be done for situations that are temporary in
nature. Only the ROT for the affected runway(s) will need
to be revalidated. All validation and revalidation
documentation must be retained and contain the following
information for each arrival:
a. Aircraft call sign.
b. Aircraft type.
c. Time across the threshold.
d. Time clear of the runway.
e. Items c and d above may be omitted if using a
stopwatch. Record the total number of seconds required for
an aircraft to proceed from over the landing threshold to
a point clear of the runway when using a stopwatch.

FAAO JO 7110.65, Subpara 5-5-4f, Minima.
10-4-12. MINIMUM IFR ALTITUDES (MIA)
At
terminal facilities that require minimum IFR altitude
(MIA) charts, determine MIA information for each control
sector and display them at the sector. This must include
off-airway minimum IFR altitude information to assist
controllers in applying 14 CFR Section 91.177 for
off-airway vectors and direct route operations. Facility
air traffic managers must determine the appropriate
chart/map method for displaying this information at the
sector. Forward charts and chart data records to Technical
Operations Aviation System Standards, National Flight
Procedures, for certification and annual review.
NOTE-
1. For guidance in the preparation and
review of Minimum IFR Altitude charts see FAAO 7210.37,
En Route Minimum IFR Altitude (MIA) Sector Charts.
2. This may be accomplished by appending the data
on sector charts or MVA charts; Special translucent
sectional charts are also available. Special ordering
information is contained in FAAO 1720.23, Distribution of
Aeronautical Charts and Related Flight Information
Publications. (Reference - para 3-8-2.) |
