Section 2. Special Operations
- Provide the following special handling to military aircraft or military contracted aircraft carrying dangerous materials when:
- The words “dangerous cargo,” or “inert devices,” or both are contained in the remarks section of the filed flight plan, or
- Certain types of military flights carrying dangerous materials require strict adherence to military regulations and flight planning along carefully selected routes. These flights must avoid heavily populated areas.
- “Inert devices” are devices containing no dangerous materials but closely resembling nuclear or explosive items that are classified as dangerous and could be easily mistaken for their dangerous counterparts.
- The pilot uses these words in radio communication.
- If it becomes necessary to issue a clearance to amend the route/altitude, advise the pilot:
- Of the proposed change, and
- The amount of delay to expect if it is necessary to maintain the present route/altitude.
- When it becomes necessary for the pilot to refuse a clearance amending his/her route/altitude, he/she will advise if the traffic delay is acceptable or if an alternate route/altitude is desired. In such cases, offer all possible assistance.
- When the aircraft is provided an en route descent, do not vector the aircraft from the planned route unless the pilot concurs.
- Use special patterns and routings in areas where they have been developed for these flights. If special patterns and routings have not been developed, employ normal procedures.
- Approve flight plans specifying celestial navigation only when it is requested for USAF or USN aircraft.
An ATC clearance must be obtained by the pilot before discontinuing conventional navigation to begin celestial navigation training. The pilot will advise when discontinuing celestial navigation and resuming conventional navigation. Celestial navigation training will be conducted within 30 NM of the route centerline specified in the en route clearance unless otherwise authorized by ATC. During celestial navigation training, the pilot will advise ATC before initiating any heading changes which exceed 20 degrees.
- Within conterminous U.S. airspace, limit celestial navigation training to transponder‐equipped aircraft within areas of radar coverage.
- Prior to control transfer, ensure that the receiving controller is informed of the nature of the celestial navigation training leg.
- When notified that an experimental aircraft requires special handling:
14 CFR Section 91.319(d)(3) requires that each person operating an aircraft with an experimental certificate must notify the control tower of the experimental nature of the aircraft when operating into or out of airports with operating control towers.
- Clear the aircraft according to pilot requests as traffic permits and if not contrary to ATC procedures.
- Once approved, do not ask the pilot to deviate from a planned action except to preclude an emergency situation.
- At locations where volume or complexity of experimental aircraft operations warrant, a letter of agreement may be consummated between the facility and operator.
When coordinated in advance and traffic permits, approve requests for special flight procedures from aircraft participating in FAA research and development test activities. These special procedures must be applied to participating aircraft/vehicles.
Special flight procedures for FAA research and development test activities must be approved by the facility air traffic manager prior to their use.
Provide expeditious handling for U.S. Government, civil or military aircraft using the code name “FLYNET.” Relay the code name as an element in the remarks position of the flight plan.
The code name “FLYNET” indicates that an aircraft is transporting a nuclear emergency team or a disaster control team to the location of a potential or actual nuclear accident or an accident involving chemical agents or hazardous materials. It is in the public interest that they reach their destination as rapidly as possible.
- Except for aircraft operating in the same altitude reservation, clear aircraft into an provided separation will be applied between successive aircraft unless otherwise covered in a letter of agreement between the military scheduling activity and the concerned ATC facility.
CLEARED INTO IR (designator).
MAINTAIN IR (designator) ALTITUDE(S),
MAINTAIN AT OR BELOW (altitude),
and if required,
CROSS (fix) AT OR LATER THAN (time).
- Unless otherwise covered in a letter of agreement between the military scheduling activity and the concerned FAA facility, clear aircraft to exit an .
CLEARED TO (destination/clearance limit) FROM IR (designator/exit fix) VIA (route).
- If the provisions of subparagraph above cannot be accomplished, s may be designated for operations. To preclude an inadvertent compromise of standards by ATC, appropriate application for such routes must be covered in a letter of agreement with the military scheduling activity. Establish separation between aircraft as soon as practicable after operation on the designated route is ended.
For designated routes, the military assumes responsibility for separation for aircraft that have passed the primary/alternate entry fix until separation is established by ATC after operations on the route are completed.
- The lateral airspace to be protected along an is the designated width of the route.
- Prior to an aircraft entering an , request the pilot's estimate for the route's exit/alternate exit fix, the pilot's requested altitude after exiting and, if applicable, the number of reentries on a Strategic Training Range (STR).
(Call sign) VERIFY YOUR EXIT FIX ESTIMATE AND REQUESTED ALTITUDE AFTER EXIT,
and if applicable,
THE NUMBER OF REENTRIES.
- Forward estimates for exit/alternate exit fixes, requested altitude after exit, and, if applicable, the number of reentries on the STR.
- Apply the procedures of paragraph , Nonreceipt of Position Report, based upon the pilot's estimate for the route exit fix.
- Clearance may be issued to amend or restrict operations on a route for ATC considerations. Where a route has been designated in accordance with subparagraph , ATC must not amend or restrict operations in such a manner as to compromise provisions.
When is provided through route scheduling and circumstances prevent the pilot from entering the route within established time limits, it must be the responsibility of the pilot to inform the ATC facility and advise his/her intentions.
- If an aircraft on an experiences a two‐way radio communications failure and you are unable to determine if the aircraft is proceeding VFR in accordance with 14 CFR Section 91.185(b) or the aircraft has not been positively radar identified:
- Provide separation to the destination airport based on the aircraft complying with the following:
- The minimum IFR altitude for each of the remaining route segment(s) remaining on the route.
- The highest altitude assigned in the last ATC clearance.
- Depart the exit/alternate exit fix at the appropriate altitude specified in subparagraph above, then climb/descend to the altitude filed in the flight plan for the remainder of the flight, or
In the event of a two‐way communications failure, ATC will be based on the following anticipated pilot action at the exit fix. Unless otherwise covered in a letter of agreement, and if the pilot is unable to comply with the VFR provisions of 14 CFR Section 91.185/FLIP IFR Supplement, the pilot will exercise his/her emergency authority, squawk transponder Code 7700, depart the exit/alternate exit fix and climb/descend (continuing to squawk 7700) to the altitude filed in the flight plan. Subsequent transponder operations will be in accordance with paragraph , Communications Failure. Air traffic controller action from the exit fix is as prescribed in paragraph , Emergency Determinations.
- Proceed in accordance with the lost communication procedure contained in letters of agreement.
- Continue to monitor the last ATC assigned discrete code.
Pilots who experience a two‐way radio failure will adjust their transponder to Code 7700 during climb/descent to altitude filed for the next leg of the flight plan; then change to Code 7600 for a period of 15 minutes. At the end of each 15-minute period, he/she will squawk 7700 for a period of 1 minute; all other times he/she will squawk 7600.
- Impose delays, if needed, to eliminate conflict with nonparticipating IFR aircraft when necessary to preclude denial of usage. Advise the pilot of the expected length and reason for delay.
Provide maximum assistance to expedite the movement of interceptor aircraft on active air defense (scrambles) missions until the unknown aircraft is identified in accordance with the policies and procedures published in FAA Order JO 7610.4, Special Operations.
The FAA and the military have mutually agreed to the implementation of policies and procedures for control of air defense interceptor operations. Effective coordination and cooperation between FAA and the military at all levels are essential if policy objectives are to be met.
- The ADCF initiating the SCRAMBLE must identify the mission as an active air defense mission.
- ATC services must be used for active air defense missions insofar as the circumstances and situation permits.
- Upon request, the ATC facility must expedite transfer of the control jurisdiction of the interceptors to the requesting ADCF.
- Immediately relay any reports or information regarding unusual aircraft activities in the vicinity of special interest sites such as nuclear power plants, power plants, dams, refineries, etc., to supervisory/CIC personnel.
Air traffic controllers have no responsibilities to monitor or observe aircraft in the vicinity of special interest sites unless directed by supervisory/CIC personnel.
The Code of Federal Regulations prescribes special air traffic rules for aircraft operating within the boundaries of certain designated airspace. These areas are listed in 14 CFR Part 93 and can be found throughout the . Procedures, nature of operations, configuration, size, and density of traffic vary among the identified areas.
- Special Flight Rules Areas are areas of airspace wherein the flight of aircraft is subject to special air traffic rules set forth in 14 CFR Part 93, unless otherwise authorized by air traffic control. Not all areas listed in 14 CFR Part 93 are Special Flight Rules Areas, but special air traffic rules apply to all areas designated as SFRA.
14 CFR Part 93, Special Air Traffic Rules.
P/CG Term - SPECIAL AIR TRAFFIC RULES (SATR)
P/CG Term - SPECIAL FLIGHT RULES AREA (SFRA)
- Each person operating an aircraft to, from, or within airspace designated as a SATR area or SFRA must adhere to the special air traffic rules set forth in 14 CFR Part 93, as applicable, unless otherwise authorized or required by ATC.
Provide ATC security services at locations where procedures are required for tracking aircraft in security services airspace. ATC security services are designed to support the national security mission of the FAA and other agencies. Two-way radio communications, flight planning, and an operational transponder on an assigned code are required for operations in the designated area.
- When the assigned code is observed, advise the aircraft to proceed on course/as requested but to remain outside of Class B, C, and/or D airspace as appropriate.
(ACID) TRANSPONDER OBSERVED PROCEED ON COURSE/AS REQUESTED; REMAIN OUTSIDE (class) AIRSPACE.
- Maintain continuous security tracking of VFR aircraft operating in the designated area to assist security forces in situational awareness. Immediately report all instances of loss of radio communication or the inability to conduct security tracking of an aircraft to the operations supervisor (OS)/CIC and wait for instructions.
- Basic separation services to aircraft, for example, IFR, SVFR, Class B, Class C, TRSA, do not apply to ATC security tracking.
- Aircraft with operating transponders, but without operating Mode C (altitude), require specific authorization from ATC to operate in the SFRA. ATC must coordinate with the Domestic Events Network (DEN) before approval.
- Aircraft flying too low for radar coverage must be instructed to report landing or exiting the SFRA. Keep flight progress strips on these aircraft until pilot reports landing or exiting the SFRA. If a flight progress strip does not exist for the aircraft, record the call sign, transponder code, entry point (for example, north, northeast, east), and time of entry into the SFRA.
(Call sign), REPORT LANDING OR LEAVING THE SFRA.
- United States military, law enforcement, and aeromedical flights are exempt from filing flight plans.
- Establishing two-way Communications.
- Pilots must establish two-way radio communications with ATC prior to entering the security service area. Responding to a radio call with, “(a/c call sign) standby,” establishes radio communications and the pilot may enter the area, provided all other security requirements have been satisfied.
- Aircraft requesting security services should not normally be held. However, if holding is necessary or workload/traffic conditions prevent immediate provision of ATC security services, inform the pilot to remain outside the designated area until conditions permit the provision of ATC security services. Inform the pilot of the expected length of delay.
(A/C call sign) REMAIN OUTSIDE OF THE (location) AND STANDBY. EXPECT (time) MINUTES DELAY.
- Termination of Service.
- If the aircraft is not landing within the designated area, provide security services until the aircraft exits the area and then advise the aircraft to squawk VFR and that frequency change is approved.
SQUAWK VFR, FREQUENCY CHANGE APPROVED.
CONTACT (facility identification).
- When an aircraft is landing at an airport inside the area, instruct the pilot to remain on the assigned transponder code until after landing.
(ACID) REMAIN ON YOUR ASSIGNED TRANSPONDER CODE UNTIL YOU LAND, FREQUENCY CHANGE APPROVED.
- Using approved handoff functionality, transfer the data blocks of all security tracked aircraft that will enter another sector/position for coordination of aircraft information/location. Upon acceptance of the transferred information, instruct the pilot to contact the next sector/positions' frequency.
Upon receiving notification of a , the controller must forward all information on the subject aircraft to the OS/CIC. If information is not known, broadcast call sign on all frequencies and advise the OS/CIC of the response.
- In the event information is received pertaining to stolen aircraft, the controller must forward all information to the OS/CIC for reporting on the Domestic Events Network (DEN).
FAA Order JO 7210.3, Para 2-7-7, Cooperation With Law Enforcement Agencies.
- Special law enforcement operations.
- Special law enforcement operations include inflight identification, surveillance, interdiction and pursuit activities performed in accordance with official civil and/or military mission responsibilities.
- To facilitate accomplishment of these special missions, exemptions from specified parts of Title 14 of the Code of Federal Regulations have been granted to designated departments and agencies. However, it is each organization's responsibility to apprise ATC of their intent to operate under an authorized exemption before initiating actual operations.
FAA Order JO 7210.3, Para 19-3-1, Authorizations and Exemptions from Title 14, Code of Federal Regulations (14 CFR).
- Additionally, some departments and agencies that perform special missions have been assigned coded identifiers to permit them to apprise ATC of ongoing mission activities and solicit special air traffic assistance.
FAA Order 7110.67, Air Traffic Management Security Services for Special Operations.
- Assistance to law enforcement aircraft operations.
- Provide the maximum assistance possible to law enforcement aircraft, when requested, in helping them locate suspect aircraft.
- Communicate with law enforcement aircraft, when possible and if requested, on a frequency not paired with your normal communications frequencies.
- Do not allow assistance to law enforcement aircraft to violate any required separation minima.
- Do not assist VFR law enforcement aircraft in any way that will create a situation which, in your judgment, places the aircraft in unsafe proximity to terrain or other aircraft.
Authorize aircraft to conduct aerial refueling along published or special tracks at their flight plan altitudes, unless otherwise requested.
CLEARED TO CONDUCT REFUELING ALONG (number) TRACK,
FROM (fix) TO (fix),
MAINTAIN BLOCK (altitude) THROUGH (altitude),
COMMENCING AT (altitude), DESCENDING TO (altitude).
- During aerial refueling, tanker aircraft are responsible for receiver aircraft communication with ATC and for their navigation along the track.
- Aerial refueling airspace is not sterilized airspace and other aircraft may transit this airspace provided vertical or lateral separation is provided from refueling aircraft.
- begins between the tanker and receiver when the tanker and receiver(s) have entered the air refueling airspace and the tanker advises ATC that he/she is accepting .
- ends between the tanker and receiver when the tanker advises ATC that the tanker and receiver aircraft are vertically positioned within the air refueling airspace and ATC advises is terminated.
- Provide radar assistance to the rendezvous for participating aircraft:
- Do not request receiver aircraft that have been cleared to conduct air refueling and have departed the ARIP to:
- Make code changes when less than 5 miles from the tanker.
- Squawk standby when less than 1 mile or more than 3 miles from the tanker.
Requests for receiver aircraft to make code changes during air refueling diverts the receiver pilot's attention during a critical phase of flight.
- When issuing an initial air refueling clearance, you may request a receiver to squawk standby when the receiver reaches a point 3 miles from the tanker.
- Receiver aircraft will squawk normal when separation from the tanker is greater than 3 miles.
- Once rendezvous is completed, heading and altitude assignments may be made with the tanker concurrence with remaining in effect.
- Upon rendezvous completion, the tanker must keep receiver aircraft within 3 miles of the tanker until is terminated.
- Do not use the altitude vacated during the refueling operation until the refueling aircraft has reported reaching the next IFR altitude.
- Approve requests by the tanker pilot for vectors or alternative routes or altitudes as follows:
- Furnish vectors or alternative altitudes at any time.
- Furnish nonradar routes only after the refueling aircraft have passed the ARCP.
- To meet a training requirement that aerial refueling be accomplished in a nonradar environment, the military has requested that vectors be furnished only upon request.
- The tanker commander is responsible for coordinating all inflight requests with other aircraft in the refueling mission before submission of such requests to the center.
- Normally, aircraft conducting aerial refueling operations will utilize at least three consecutive altitudes.
- Unless a vector or alternative route has been furnished, clear the aircraft to depart the refueling track at a navigational reference point or egress fix.
- Request an aircraft to report the ARIP, ARCP, or egress fix as necessary.
- Expect the following procedures in addition to those required by the appropriate parts of Title 14 of the Code of Federal Regulations in the event of two‐way communications failure:
- The tanker will depart the track from the highest altitude in the block.
- The receiver will depart the track from the lowest altitude in the block.
- Aircraft will squawk 7600 for at least 2 minutes prior to departing the track.
Control aircraft operating above FL 600 using the following procedures:
- Flight plans involving supersonic flight are required 16 hours in advance of proposed departure times for processing and approval by the s concerned. The originating , where the flight plan is first filed, may waive the 16-hour advance filing requirement.
- The route of flight must be defined by at least one high altitude fix within each area without regard to the distance between fixes. Additionally, the entry and exit points of turns of 90 degrees or more will be designated.
- Elapsed times from takeoff to the first fix in each area must be included in the route of flight.
- The which originates the flight plan must forward departure times to all s responsible for processing the flight plan.
- Approval of the flight plan indicates approval of both route and flight levels (if stated) including operations below FL 600 (aerial refueling).
CLEARED AS FILED VIA ROUTE AND FLIGHT LEVELS.
- Separation. Use the following as minima in lieu of the corresponding type of separation prescribed in:
The primary method described to provide separation between two supersonic aircraft is to descend the aircraft at the lower FL and provide vertical separation since the aircraft at the higher FL may not be able to climb rapidly enough to establish the required separation. Another aspect which should be considered is that supersonic aircraft during turns, either programmed or as the result of vectors, will lose a few thousand feet. Vectoring supersonic aircraft seriously affects the range and mission objectives. Radar separation is the preferred method of separating a subsonic aircraft both from another subsonic aircraft or from a supersonic aircraft.
- The security requirements of the military services preclude the transmission of actual altitude information on the air/ground or landline circuits. Altitude information for the day should be readily available to the controllers at their positions of operation. The classification requirements of the altitude information remains unchanged.
- Pilots will report their altitude, using the coded plan, and intended flight profile on initial contact with each .
- Paragraph , Minima Along Other Than Established Airways or Routes: Protect the airspace 25 miles either side of the route centerline. For turns by supersonic aircraft, protect the airspace 75 miles on the overflown side and 25 miles on the other side. For turns by subsonic aircraft, protect the airspace 34 miles on the overflown side and 25 miles on the other side.
Special use frequencies are assigned to s in such a manner that adjacent s will not have the same frequency. They are to be used within the area jurisdiction from the established FL base of the high altitude sectors and above. Each high altitude sector should have the capability to use the special use frequency on a shared basis.
- USAF, U.S. Navy, and Air National Guard (ANG) single‐pilot jet aircraft formations operating at night or in instrument weather conditions. Formations of five or more USAF aircraft deploying either to a continental U.S. staging base or nonstop to an overseas location are authorized to use special use frequencies at any time. Normally these deployments will be conducted within an altitude reservation.
- U-2 and B-57 (pressure suit flights) aircraft at all altitudes/FLs except where terminal operations require the assignment of other frequencies.
Aerial refueling operations may require that aircraft leave the special use frequency for communications with the tanker. This will occur when the receiver is approximately 200 miles from the ARCP. The tanker aircraft will remain on the assigned frequency and will relay clearances to the receiver as required. An alternate means of communications between the tanker and receiver is radio.
- All aircraft during supersonic flight.
Pilots are expected to request assignment of the special use frequency in the remarks section of the flight plan or before entering supersonic flight. B-57 aircraft engaged in pressure suit operations will use the static call sign KITE and flights will normally be conducted from Dover, Eielson, Ellington, Hickman, Howard, Kirtland, and McClellan Air Force Bases.
- E-3A AWACS mission crews when operations are being conducted as an MRU in accordance with appropriate letters of agreement.
- The special use frequency may be assigned as “backup” for the high‐altitude sector when direct communications are essential because of a potential emergency control situation.
- Do not assign the special use frequency to the aircraft in subparagraph above, when they will operate in airspace assigned for special military operations.
- Advise pilots whenever their proposed flight path will traverse a reported or forecasted area of hazardous radiation and reroute the aircraft when requested by the pilot.
FAA Order JO 7610.4, Para 4-4-4, Avoidance of Hazardous Radiation Areas.
- Inform pilots when an airfield of intended landing lies within a reported or forecasted area of hazardous radiation and request the pilot to advise his/her intentions.
Provide special handling to U.S. Government and military aircraft engaged in aerial sampling/surveying missions, sampling for nuclear, chemical, or hazardous material contamination. Honor inflight clearance requests for altitude and route changes to the maximum extent possible. Other IFR aircraft may be recleared so that requests by SAMP aircraft are honored. Separation standards as outlined in this order must be applied in all cases.
Do not delay E-3 AWACS aircraft identified as “AWACS/NORAD Special” flights. The following control actions are acceptable while expediting these aircraft to the destination orbit.
- En route altitude changes +/- 2,000 feet from the requested flight level.
- Radar vectors or minor route changes that do not impede progress towards the destination orbit.
NORAD has a requirement to position E-3 AWACS aircraft at selected locations on a time‐critical basis. To the extent possible these flights will utilize routes to the destination orbit that have been precoordinated with the impacted ATC facilities. To identify these flights, the words “AWACS/NORAD SPECIAL” will be included as the first item in the remarks section of the flight plan.
TEAL and NOAA mission aircraft fly reconnaissance flights to gather meteorological data on winter storms, (NWSOP missions), hurricanes and tropical cyclones (NHOP missions). The routes and timing of these flights are determined by movement of the storm areas and not by traffic flows.
- When a dropsonde release time is received from a TEAL or NOAA mission aircraft, workload and priorities permitting, controllers must advise the mission aircraft of any traffic estimated to pass through the area of the drop at altitudes below that of the mission aircraft. This traffic advisory must include:
- Direction of flight.
- at the point closest to drop area (or at the fix/intersection where drop will occur).
A dropsonde is a 14-inch long cardboard cylinder about 2.75 inches in diameter, that weighs approximately 14 ounces (400 grams), and has a parachute attached. When released from the aircraft it will fall at a rate of approximately 2,500 feet per minute. Controllers should recognize that a dropsonde released at FL 310 will be a factor for traffic at FL 210 four minutes later. It is the aircraft commanders responsibility to delay release of dropsondes if traffic is a factor. Aircraft commanders will delay release of dropsondes based solely upon traffic as issued by ATC.
- When advised that an airborne TEAL or NOAA aircraft is requesting a clearance via CARCAH, issue the clearance in accordance with , IFR, , Clearances.
- If a TEAL or NOAA mission aircraft must be contacted but is out of VHF, UHF, and radio range, advise the supervisory traffic management coordinator-in-charge.
- Aircraft operations associated with a Weather Reconnaissance Area (WRA) must be conducted in accordance with the Memorandum of Agreement between the National Oceanic and Atmospheric Administration Aircraft Operations Center, U.S. Air Force Reserve Command 53rd Weather Reconnaissance Squadron, and the Federal Aviation Administration Air Traffic Organization in Support of the National Hurricane Operations Plan (FAA Order JO 7610.4, Appendix 3), and the associated letters of agreement.
Approve a pilot request to conduct an evasive action maneuver only on the basis of a permissible traffic situation. Specify the following items, as necessary, when issuing approval:
The “evasive action” maneuver is performed by a bomber/fighter bomber aircraft at or above FL 250 along a 60 NM long segment of the flight plan route overlying a RBS or other site and includes:
- Flying a zigzag pattern on both the left and right side of the flight plan route centerline. Altitude deviations are made in conjunction with the lateral maneuvering.
- Lateral deviations from the route centerline will not normally exceed 12 miles. Altitude variations must not exceed plus or minus 1,000 feet of the assigned flight level; i.e., confined within a 2,000 foot block.
- Specific route segment on which the maneuver will take place.
- Distance of maximum route deviation from the centerline in miles.
CLEARED TO CONDUCT EVASIVE ACTION
MANEUVER FROM (fix) TO (fix),
(number of miles) EITHER SIDE OF CENTERLINE,
MAINTAIN (altitude) THROUGH (altitude),
COMPLETE MANEUVER AT (fix) AT (altitude).
Occasionally the military is required to operate in a nonstandard cell formation and controllers should be knowledgeable of the various tactics employed and the procedures used.
FAA Order JO 7610.4, Chapter 12, Section 11, Formation Flight.
- Formation leaders are responsible for obtaining ATC approval to conduct nonstandard formation/cell operations.
- When nonstandard formation/cell operations have been approved, controllers must assign sufficient altitudes to allow intra‐cell vertical spacing of 500 feet between each aircraft in the formation.
- Control nonstandard formation/cell operations on the basis that is applicable between the participating aircraft until they establish approved separation which is acknowledged by ATC.
- Apply approved separation criteria between the approved nonstandard formation/cell envelope and nonparticipating aircraft.
- Clear aircraft operating in a nonstandard formation/cell to the breakup fix as the clearance limit. Forward data pertaining to route or altitude beyond the breakup point to the center concerned as a part of the routine flight plan information.
- EN ROUTE. If the breakup occurs in your area, issue appropriate clearances to authorize transition from formation to individual routes or altitudes. If a breakup cannot be approved, issue an appropriate clearance for the flight to continue as a formation.
- Open Skies aircraft will be identified by the call sign “OSY” (Open Skies) followed by the flight number and a one-letter mission suffix.
*F = Observation Flights (Priority).
*D = Demonstration Flights (Priority).
*T = Transit Flights (Nonpriority).
- Observation/Demonstration flights are conducted under rigid guidelines outlined in the Treaty on Open Skies that govern sensor usage, maximum flight distances, altitudes and priorities.
- Transit flights are for the sole purpose of moving an Open Skies aircraft from airport to airport in preparation for an actual Open Skies “F” or “D” mission.
- Provide priority and special handling to expedite the movement of an Open Skies observation or demonstration flight.
- Open Skies (F and D) Treaty aircraft, while maintaining compliance with ATC procedures, must have priority over activities in special use airspace (SUA)/Air Traffic Control Assigned Airspace (). Open Skies (F and D) Treaty aircraft are nonparticipating aircraft and must be allowed to transit SUA/ as filed after appropriate and timely coordination has been accomplished between the using agency and controlling agency.
A letter of agreement is not required for nonparticipating aircraft to transit deactivated/released airspace.
- The ATC facility controlling the Open Skies (F and D) Treaty flight must advise the using agency, or appropriate ATC facility, upon initial notification and when the aircraft is 30 minutes from the SUA/ boundary; and
- For active SUA/ with an ATC facility, coordinate and execute the transit of Open Skies (F and D) Treaty aircraft.
- For active SUA/ without an ATC facility, the using agency must deactivate/release the SUA/ to permit the Open Skies (F and D) Treaty aircraft to transit as filed in proximity to the active SUA/. When deactivating/releasing the SUA/ for this purpose, the using agency is only required to deactivate/release the portion of the SUA/ to the controlling agency that is necessary to provide approved separation.
- The using agency must deactivate/release the SUA/, or portion thereof, no later than 15 minutes prior to the Open Skies (F and D) Treaty aircraft reaching the SUA/ boundary.
- If the controlling agency is unable to confirm with the using agency that all conflicting activities in the SUA/ have ceased, the Open Skies aircraft must not be permitted access to the SUA/.
- Return SUA/ to the using agency, if requested, within (15) minutes after the Open Skies (F and D) Treaty aircraft clears the SUA/.
- Clear the aircraft according to the filed flight plan.
- Do not ask the pilot to deviate from the planned action or route of flight except to preclude an emergency situation or other higher priority aircraft.
- Do not impose air traffic control delays except to preclude emergency situations or other higher priority aircraft.
If for reasons of flight safety the route or altitude must be changed, return the aircraft to the filed flight plan route as soon as practical.
