Chapter 2. General Control
Section 1. General
2-1-1. ATC SERVICE
- The primary purpose of the ATC system is to prevent a collision involving aircraft operating in the system.
- In addition to its primary purpose, the ATC system also:
- Provides a safe, orderly, and expeditious flow of air traffic.
- Supports National Security and Homeland Defense missions.
- The ATC system must provide certain additional services to the extent permitted. The provision of additional services is not optional on the part of the controller, but rather required when the work situation permits. It is recognized that the provision of these services may be precluded by various factors, including, but not limited to:
- Volume of traffic.
- Frequency congestion.
- Quality of surveillance.
- Controller workload.
- Higher priority duties.
- The physical inability to scan and detect situations falling in this category.
- Controllers must provide air traffic control service in accordance with the procedures and minima in this order, except when one or more of the following conditions exists:
- A deviation is necessary to conform with ICAO Documents, National Rules of the Air, or special agreements where the U.S. provides air traffic control service in airspace outside the U.S. and its possessions or:
- Other procedures/minima are prescribed in a letter of agreement, FAA directive, or a military document, or:
- A deviation is necessary to assist an aircraft when an emergency has been declared.
- Air Traffic Control services are not provided for model aircraft operating in the NAS or to any UAS operating in the NAS at or below 400ft AGL.
2-1-2. DUTY PRIORITY
- Give first priority to separating aircraft and issuing safety alerts as required in this order. Good judgment must be used in prioritizing all other provisions of this order based on the requirements of the situation at hand.
- Provide support to national security and homeland defense activities to include, but not be limited to, reporting of suspicious and/or unusual aircraft/pilot activities.
- Provideand/or solicit weather information in accordance with procedures and requirements outlined in this order.
- Provide additional services to the extent possible, contingent only upon higher priority duties and other factors including limitations of radar, volume of traffic, frequency congestion, and workload.
2-1-3. PROCEDURAL PREFERENCE
- Use automation procedures in preference to nonautomation procedures when workload, communications, and equipment capabilities permit.
- Use automation procedures that provide closed loop clearances in preference to open loop clearances to promote operational advantage for time-based management (TBM) when workload permits. (e.g., a QU route pick that anticipates length of vector and includes the next fix that ties into the route of flight.)
- Use radar separation in preference to nonradar separation when it will be to an operational advantage and workload, communications, and equipment permit.
- Use nonradar separation in preference to radar separation when the situation dictates that an operational advantage will be gained.
2-1-4. OPERATIONAL PRIORITY
It is recognized that traffic flow may affect the controller's ability to provide priority handling. However, without compromising safety, good judgment must be used in each situation to facilitate the most expeditious movement of priority aircraft. Provide air traffic control service to aircraft on a “first come, first served” basis as circumstances permit, except the following:
- An aircraft in distress has the right of way over all other air traffic.
- Treat air ambulance flights as follows:
- Provide priority handling to civil air ambulance flights when the pilot, in radio transmissions, verbally identifies the flight by stating “MEDEVAC” followed by the FAA authorized call sign or the full civil registration letters/numbers. Good judgment must be used in each situation to facilitate the most expeditious movement of a MEDEVAC aircraft.
- Provide priority handling to AIR EVAC and HOSP flights when verbally requested by the pilot.
- Assist the pilots of MEDEVAC, AIR EVAC, and HOSP aircraft to avoid areas of significant weather and adverse conditions.
- If requested by a pilot, provide additional assistance (i.e., landline notifications) to expedite ground handling of patients, vital organs, or urgently needed medical materials.
- Provide priority handling and expedite the movement of presidential aircraft and entourage and any rescue support aircraft as well as related control messages when traffic conditions and communications facilities permit.
- Provide priority handling and maximum assistance to SAR aircraft performing a SAR mission.
- Provide priority handling and maximum assistance to expedite the movement of interceptor aircraft on active air defense missions until the unknown aircraft is identified.
- Provide priority handling to NIGHT WATCH “NAOC” (pronounced NAY-OCK) aircraft when notified via landline or when “NAOC” is used in air/ground communications. When the term “NAOC” is used, approve any request(s) as soon as practicable.
- Provide priority handling to any civil or military aircraft using the code name “FLYNET."
- Provide priority handling to aircraft using the code name “Garden Plot” only when CARF notifies you that such priority is authorized. Refer any questions regarding flight procedures to CARF for resolution.
- Provide priority handling to USAF or other government aircraft engaged in aerial sampling/surveying missions using the call sign “SAMP.”
- Provide priority handling to Special Air Mission “SCOOT” aircraft when notified via landline or when “SCOOT” is used in air/ground communications. When the term “SCOOT” is used, approve any request(s) as soon as practicable.
- When requested, provide priority handling to TEAL and NOAA mission aircraft.
- Provide priority handling, as required to expedite Flight Check aircraft.
- IFR aircraft must have priority over SVFR aircraft.
- Aircraft operating under the North American Route Program (NRP) are not subject to route limiting restrictions (e.g., published preferred IFR routes, letter of agreement requirements, standard operating procedures).
- If able, provide priority handling to diverted flights. Priority handling may be requested via use of “DVRSN" in the remarks section of the flight plan or by the flight being placed on the Diversion Recovery Tool (DRT).
- If able, provide priority handling to FALLEN HERO flights when “FALLEN HERO" is indicated in the remarks section of the flight plan or requested in air/ground communications.
2-1-5. EXPEDITIOUS COMPLIANCE
- Use the word “immediately” only when expeditious compliance is required to avoid an imminent situation.
- Use the word “expedite” only when prompt compliance is required to avoid the development of an imminent situation. If an “expedite" climb or descent clearance is issued by ATC, and subsequently the altitude to maintain is changed or restated without an expedite instruction, the expedite instruction is canceled.
- In either case, if time permits, include the reason for this action.
2-1-6. SAFETY ALERT
Issue a safety alert to an aircraft if you are aware the aircraft is in a position/altitude that, in your judgment, places it in unsafe proximity to terrain, obstructions, or other aircraft. Once the pilot informs you action is being taken to resolve the situation, you may discontinue the issuance of further alerts. Do not assume that because someone else has responsibility for the aircraft that the unsafe situation has been observed and the safety alert issued; inform the appropriate controller.
- Terrain/Obstruction Alert. Immediately issue/initiate an alert to an aircraft if you are aware the aircraft is at an altitude that, in your judgment, places it in unsafe proximity to terrain and/or obstructions. Issue the alert as follows:
- Aircraft Conflict/Mode C Intruder Alert. Immediately issue/initiate an alert to an aircraft if you are aware of another aircraft at an altitude that you believe places them in unsafe proximity. If feasible, offer the pilot an alternate course of action. When an alternate course of action is given, end the transmission with the word “immediately.”
2-1-7. INFLIGHT EQUIPMENT MALFUNCTIONS
- When a pilot reports an inflight equipment malfunction, determine the nature and extent of any special handling desired.
- Provide the maximum assistance possible consistent with equipment, workload, and any special handling requested.
- Relay to other controllers or facilities who will subsequently handle the aircraft, all pertinent details concerning the aircraft and any special handling required or being provided.
2-1-8. MINIMUM FUEL
If an aircraft declares a state of “minimum fuel,” inform any facility to whom control jurisdiction is transferred of the minimum fuel problem and be alert for any occurrence which might delay the aircraft en route.
2-1-9. REPORTING ESSENTIAL FLIGHT INFORMATION
Report as soon as possible to the appropriate FSS, airport manager's office, ARTCC, approach control facility, operations office, or military operations office any information concerning components of the NAS or any flight conditions which may have an adverse effect on air safety.
2-1-10. NAVAID MALFUNCTIONS
- When an aircraft reports a ground-based NAVAID malfunction, take the following actions:
- Request a report from a second aircraft.
- If the second aircraft reports normal operations, continue use and inform the first aircraft. Record the incident on FAA Form 7230-4 or appropriate military form.
- If the second aircraft confirms the malfunction or in the absence of a second aircraft report, activate the standby equipment or request the monitor facility to activate.
- If normal operation is reported after the standby equipment is activated, continue use, record the incident on FAA Form 7230-4 or appropriate military form, and notify technical operations personnel (the Systems Engineer of the ARTCC when an en route aid is involved).
- If continued malfunction is reported after the standby equipment is activated or the standby equipment cannot be activated, inform technical operations personnel and request advice on whether or not the aid should be shut down. In the absence of a second aircraft report, advise the technical operations personnel of the time of the initial aircraft report and the estimated time a second aircraft report could be obtained.
- When an aircraft reports a GPS or WAASanomaly, request the following information and/or take the following actions:
- Record the following minimum information:
- Aircraft make, model, and call sign.
- Locationor position, and altitude at the time where GPS or WAAS anomaly was observed.
- Date/time of occurrence.
- Request a report from a second aircraft.
- Record the incident on FAA Form 7230-4 or appropriate military form.
- Inform other aircraft of the anomaly as specified in subparagraph 4-8-1k, l, or m, as applicable.
- Record the following minimum information:
- When a pilot reports a WAAS anomaly, determine from the pilot what indications he or she observes and record the information in accordance with subparagraph b above.
2-1-11. USE OF MARSA
- MARSA may only be applied to military operations specified in a letter of agreement or other appropriate FAA or military document.
- ATC facilities do not invoke or deny MARSA. Their sole responsibility concerning the use of MARSA is to provide separation between military aircraft engaged in MARSA operations and other nonparticipating IFR aircraft.
- DoD must ensure that military pilots requesting special use airspace/ATCAAs have coordinated with the scheduling agency, have obtained approval for entry, and are familiar with the appropriate MARSA procedures. ATC is not responsible for determining which military aircraft are authorized to enter special use airspace/ATCAAs.
2-1-12. MILITARY PROCEDURES
Military procedures in the form of additions, modifications, and exceptions to the basic FAA procedure are prescribed herein when a common procedure has not been attained or to fulfill a specific requirement. They must be applied by:
- ATC facilities operated by that military service.
- ATC facilities, regardless of their parent organization (FAA, USAF, USN, USA), supporting a designated military airport exclusively. This designation determines which military procedures are to be applied.
- Other ATC facilities when specified in a letter of agreement.
2-1-13. FORMATION FLIGHTS
Control formation flights as a single aircraft. Separation responsibility between aircraft within the formation rests with the flight leader and the pilots of the other aircraft in the flight. This includes transition periods when aircraft within the formation are maneuvering to attain separation from each other to effect individual control during join-up and breakaway.
- Support formation flight join-up for two aircraft when all of the following occur:
- Requested by any participating pilot.
- All participating pilots concur.
- Either of the participating pilots reports the other/s in sight.
- If multiple single aircraft request to join-up, multiple formations are joining as one, or aircraft are joining an established formation, obtain confirmation of required items listed in subparagraph 2-1-13a, from the lead aircraft.
- After join-up, aircraft beacon code assignment will be determined by formation type.
- For a standard formation only the aircraft acting as the lead will squawk an ATC assigned beacon code. Ensure all other aircraft squawk standby.
- For a nonstandard formation, each aircraft should squawk an ATC assigned beacon code. Controller discretion allows aircraft in a nonstandard formation to squawk standby if operationally advantageous.
- When formation break-up is requested, issue control instructions and/or clearances which will result in approved separation through the lead or directly to the requesting aircraft in the formation.
- Military and civil formation flights in RVSM airspace.
- Utilize RVSM separation standards for a formation flight, which consists of all RVSM approved aircraft.
- Utilize non-RVSM separation standards for a formation flight at or above FL 290, which does not consist of all RVSM approved aircraft.
- If aircraft are requesting to form a formation flight to FL 290 or above, the controller who issues the clearance creating the formation flight is responsible for ensuring that the proper equipment suffix is entered for the lead aircraft.
- If the flight departs as a formation, and is requesting FL 290 or above, the first center sector must ensure that the proper equipment suffix is entered.
- If the formation flight is below FL 290 and later requests FL 290 or above, the controller receiving the RVSM altitude request must ensure the proper equipment suffix is entered.
- Upon break-up of the formation flight, the controller initiating the break-up must ensure that all aircraft or flights are assigned their proper equipment suffix.
2-1-14. COORDINATE USE OF AIRSPACE
- Ensure that the necessary coordination has been accomplished before you allow an aircraft under your control to enter another controller's area of jurisdiction.
- Before you issue a control instruction directly to a pilot that will change the aircraft's heading, route, speed, or altitude, you must ensure that coordination has been completed with all controllers whose area of jurisdiction is affected by those instructions unless otherwise specified by a letter of agreement or facility directive. If your control instruction will be relayed to the pilot through a source other than another radar controller (FSS, New York Radio, San Francisco Radio, another pilot, etc.), you are still responsible to ensure that all required coordination is completed.
2-1-15. CONTROL TRANSFER
- Transfer control of an aircraft in accordance with the following conditions:
- At a prescribed or coordinated location, time, fix, or altitude; or,
- At the time a radar handoff and frequency change to the receiving controller have been completed and when authorized by a facility directive or letter of agreement which specifies the type and extent of control that is transferred.
- Transfer control of an aircraft only after eliminating any potential conflict with other aircraft for which you have separation responsibility.
- Assume control of an aircraft only after it is in your area of jurisdiction unless specifically coordinated or as specified by letter of agreement or a facility directive.
2-1-16. SURFACE AREAS
- Coordinate with the appropriate nonapproach control tower on an individual aircraft basis before issuing a clearance which would require flight within a surface area for which the tower has responsibility unless otherwise specified in a letter of agreement.
- Coordinate with the appropriate control tower for transit authorization when you are providing radar traffic advisory service to an aircraft that will enter another facility's airspace.
- Transfer communications to the appropriate facility, if required, prior to operation within a surface area for which the tower has responsibility.
2-1-17. RADIO COMMUNICATIONS
- Transfer radio communications before an aircraft enters the receiving controller's area of jurisdiction unless otherwise coordinated or specified by a letter of agreement or a facility directive.
- Transfer radio communications by specifying the following:
- The facility name or location name and terminal function to be contacted. TERMINAL: Omit the location name when transferring communications to another controller within your facility, or, when the tower and TRACON share the same name (for example, Phoenix Tower and Phoenix TRACON).
EXCEPTION. Controllers must include the name of the facility when instructing an aircraft to change frequency for final approach guidance.
- Frequency to use except the following may be omitted:
- FSS frequency.
- Departure frequency if previously given or published on a SID chart for the procedure issued.
- TERMINAL:
- Ground or local control frequency if in your opinion the pilot knows which frequency is in use.
- The numbers preceding the decimal point if the ground control frequency is in the 121 MHz bandwidth.
- Time, fix, altitude, or specifically when to contact a facility. You may omit this when compliance is expected upon receipt.
- The facility name or location name and terminal function to be contacted. TERMINAL: Omit the location name when transferring communications to another controller within your facility, or, when the tower and TRACON share the same name (for example, Phoenix Tower and Phoenix TRACON).
- Controllers must, within a reasonable amount of time, take appropriate action to establish/restore communications with all aircraft for which a communications transfer or initial contact to his/her sector is expected/required.
- ERAM facilities, beginning with initial audio contact with an aircraft, must utilize the voice communication indicator to reflect the current status of voice communications.
- In situations where an operational advantage will be gained, and following coordination with the receiving controller, you may instruct aircraft on the ground to monitor the receiving controller's frequency.
- In situations where a sector has multiple frequencies or when sectors are combined using multiple frequencies and the aircraft will remain under your jurisdiction, transfer radio communication by specifying the following:
- Avoid issuing a frequency change to helicopters known to be single‐piloted during air‐taxiing, hovering, or low‐level flight. Whenever possible, relay necessary control instructions until the pilot is able to change frequency.
- In situations where the controller does not want the pilot to change frequency but the pilot is expecting or may want a frequency change, use the following phraseology.
2-1-18. OPERATIONAL REQUESTS
Respond to a request from another controller, a pilot or vehicle operator by one of the following verbal means:
- Restate the request in complete or abbreviated terms followed by the word “APPROVED.” The phraseology “APPROVED AS REQUESTED” may be substituted in lieu of a lengthy readback.
- State restrictions followed by the word “APPROVED.”
- State the word “UNABLE” and, time permitting, a reason.
- State the words “STAND BY.”
2-1-19. WAKE TURBULENCE
- Apply wake turbulence procedures to an aircraft operating behind another aircraft when wake turbulence separation is required.
- The separation minima must continue to touchdown for all IFR aircraft not making a visual approach or maintaining visual separation.
2-1-20. WAKE TURBULENCE CAUTIONARY ADVISORIES
- Issue wake turbulence cautionary advisories including the position, altitude if known, and direction of flight to aircraft operating behind an aircraft that requires wake turbulence separation when:
- TERMINAL.VFR aircraft not being radar vectored are behind the larger aircraft.
- IFR aircraft accept a visual approach or visual separation.
- TERMINAL. VFR arriving aircraft that have previously been radar vectored and the vectoring has been discontinued.
- Issue cautionary information to any aircraft if in your opinion, wake turbulence may have an adverse effect on it. When traffic is known to be a Super aircraft, include the word Super in the description. When traffic isknown to be a Heavyaircraft, include the word Heavy in the description.
2-1-21. TRAFFIC ADVISORIES
Unless an aircraft is operating within Class A airspace or omission is requested by the pilot, issue traffic advisories to all aircraft (IFR or VFR) on your frequency when, in your judgment, their proximity may diminish to less than the applicable separation minima. Where no separation minima applies, such as for VFR aircraft outside of Class B/Class C airspace, or a TRSA, issue traffic advisories to those aircraft on your frequency when in your judgment their proximity warrants it. Provide this service as follows:
- To radar identified aircraft:
- Azimuth from aircraft in terms of the 12-hour clock, or
- When rapidly maneuvering aircraft prevent accurate issuance of traffic as in 1 above, specify the direction from an aircraft's position in terms of the eight cardinal compass points (N, NE, E, SE, S, SW, W, and NW). This method must be terminated at the pilot's request.
- Distance from aircraft in miles.
- Direction in which traffic is proceeding and/or relative movement of traffic.
- If known, type of aircraft and altitude.
- When requested by the pilot, issue radar vectors to assist in avoiding the traffic, provided the aircraft to be vectored is within your area of jurisdiction or coordination has been effected with the sector/facility in whose area the aircraft is operating. If unable to provide radar vectors, inform the pilot.
- Inform the pilot of the following when traffic you have issued is not reported in sight:
- The traffic is no factor.
- The traffic is no longer depicted on radar.
- To aircraft that are not radar identified:
- Distance and direction from fix.
- Direction in which traffic is proceeding.
- If known, type of aircraft and altitude.
- ETA over the fix the aircraft is approaching, if appropriate.
- For aircraft displaying Mode C, not radar identified, issue indicated altitude.
2-1-22. UNMANNED AIRCRAFT SYSTEM (UAS) ACTIVITY INFORMATION.
- Issue UAS advisory information for known UAS activity, when in your judgment their proximity warrants it. If known, include position, distance, course, type of unmanned aircraft (UA), and altitude.
- Issue UAS advisory information for pilot-reported or tower-observed activity, when in your judgment, their proximity warrants it. If known, include position, altitude, course, and type. Continue to issue advisories to potentially impacted aircraft for at least 15 minutes following the last report.
2-1-23. BIRD ACTIVITY INFORMATION
- Issue advisory information on pilot‐reported, tower‐observed, or radar‐observed and pilot‐verified bird activity. Include position, species or size of birds, if known, course of flight, and altitude. Do this for at least 15 minutes after receipt of such information from pilots or from adjacent facilities unless visual observation or subsequent reports reveal the activity is no longer a factor.
- Relay bird activity information to adjacent facilities and to FSSs whenever it appears it will become a factor in their areas.
2-1-24. TRANSFER OF POSITION RESPONSIBILITY
The transfer of position responsibility must be accomplished in accordance with the “Standard Operating Practice (SOP) for the Transfer of Position Responsibility,” and appropriate facility directives each time operational responsibility for a position is transferred from one specialist to another.
2-1-25. WHEELS DOWN CHECK
USA/USN
Remind aircraft to check wheels down on each approach unless the pilot has previously reported wheels down for that approach.
- Tower must issue the wheels down check at an appropriate place in the pattern.
- Approach/arrival control, GCA must issue the wheels down check as follows:
- To aircraft conducting ASR, PAR, or radar monitored approaches, before the aircraft starts descent on final approach.
- To aircraft conducting instrument approaches and remaining on the radar facility's frequency, before the aircraft passes the outer marker/final approach fix.
2-1-26. SUPERVISORY NOTIFICATION
Ensure supervisor/controller‐in‐charge (CIC) is aware of conditions which impact sector/position operations including, but not limited to, the following:
- Weather.
- Equipment status.
- Potential sector overload.
- Emergency situations.
- Special flights/operations.
- Aircraft/pilot activity, including unmanned aircraft system (UAS) operation that is considered suspicious, as prescribed in FAA Order JO 7610.4, paragraph 7-3-1, and for information more specific to UAS, FAA Order JO 7210.3, paragraph 2-1-34.
2-1-27. POSSIBLE PILOT DEVIATION NOTIFICATION
When it appears that the actions of a pilot constitute a pilot deviation, notify the pilot, workload permitting.
2-1-28. TCAS RESOLUTION ADVISORIES
- When an aircraft under your control jurisdiction informs you that it is responding to a TCAS Resolution Advisory (RA), do not issue control instructions that are contrary to the RA procedure that a crew member has advised you that they are executing. Provide safety alerts regarding terrain or obstructions and traffic advisories for the aircraft responding to the RA and all other aircraft under your control jurisdiction, as appropriate.
- Unless advised by other aircraft that they are also responding to a TCAS RA, do not assume that other aircraft in the proximity of the responding aircraft are involved in the RA maneuver or are aware of the responding aircraft's intended maneuvers. Continue to provide control instructions, safety alerts, and traffic advisories as appropriate to such aircraft.
- Once the responding aircraft has begun a maneuver in response to an RA, the controller is not responsible for providing approved separation between the aircraft that is responding to an RA and any other aircraft, airspace, terrain or obstructions. Responsibility for approved separation resumes when one of the following conditions is met:
- The responding aircraft has returned to its assigned altitude, or
- A crew member informs you that the TCAS maneuver is completed and you observe that approved separation has been reestablished, or
- The responding aircraft has executed an alternate clearance and you observe that approved separation has been reestablished.
2-1-29. RVSM OPERATIONS
RVSM operations are conducted in RVSM airspace that is defined as any airspace between FL 290 and FL 410 inclusive, where eligible aircraft are separated vertically by 1,000 feet.Controller responsibilities must include but not be limited to the following:
- Non‐RVSM aircraft operating in RVSM airspace.
- Ensure non-RVSM aircraft are not permitted in RVSM airspace unless they meet the criteria of excepted aircraft and are previously approved by the operations supervisor/CIC. The following aircraft are excepted: DoD, DoD-certified aircraft operated by NASA (T38, F15, F18, WB57, S3, and U2 aircraft only), MEDEVAC, manufacturer aircraft being flown for development/certification, and Foreign State aircraft. These exceptions are accommodated on a workload or traffic-permitting basis.
- Ensure sector‐to‐sector coordination for all non‐RVSM aircraft operations within RVSM airspace.
- Inform the operations supervisor/CIC when a non‐RVSM exception flight is denied clearance into RVSM airspace or is removed from RVSM airspace.
- Non-RVSM aircraft transitioning RVSM airspace.
Ensure that operations supervisors/CICs are made aware when non‐RVSM aircraft are transitioning through RVSM airspace.
- Apply appropriate separation standards and remove any aircraft from RVSM airspace that advises it is unable RVSM due to equipment while en route.
- Use “negative RVSM" in all verbal ground‐to‐ground communications involving non‐RVSM aircraft while cleared to operate within RVSM airspace.
- For the following situations, use the associated phraseology:
- To deny clearance into RVSM airspace.
- To request a pilot to report when able to resume RVSM.
- In the event of a change to an aircraft's RVSM eligibility, amend the RVSM qualifier (“W”) in theICAO equipment string in order to properly identify non‐RVSM aircraft on the controller display.
- ATC may allow aircraft to remain in RVSM airspace using reduced vertical separation minima after the loss of a transponder or Mode C altitude reporting.
2-1-30. TERRAIN AWARENESS WARNING SYSTEM (TAWS) ALERTS
- When an aircraft under your control jurisdiction informs you that it is responding to a TAWS (or other on‐board low altitude) alert, do not issue control instructions that are contrary to the TAWS procedure that a crew member has advised you that they are executing. Provide safety alerts regarding terrain or obstructions and traffic advisories for the aircraft responding to the TAWS alert and all other aircraft under your control jurisdiction, as appropriate.
- Once the responding aircraft has begun a maneuver in response to TAWS alert, the controller is not responsible for providing approved separation between the aircraft that is responding to a TAWS alert and any other aircraft, airspace, terrain or obstructions. Responsibility for approved separation resumes when one of the following conditions is met:
- The responding aircraft has returned to its assigned altitude, or
- A crew member informs you that the TAWS maneuver is completed and you observe that approved separation has been reestablished, or
- The responding aircraft has executed an alternate clearance and you observe that approved separation has been reestablished.
2-1-31. “BLUE LIGHTNING” EVENTS
Ensure that the supervisor/controller‐in‐charge (CIC) is notified of reports of possible human trafficking. These may be referred to as “Blue Lightning” events.
