(5) (ICAO) – The definition is taken from the ICAO Document 9569, Definitions and is different than that in the P/CG. (6) (USA, USN, USAF, NGA, CBP, etc.) - The definition has been originated by the agency indicated within the parentheses. This definition does not appear in the FAA P/CG, or JCS, NATO, or ICAO documents. (7) (IFIM) – The definition is taken from the FAA International Flight Information Manual. (8) (GPH 204) – The definition is taken from DND Flight Information Publication – GPH 204. (9) (DODI) – The definition is taken from DoDI 4540.01, “Use of International Airspace by U.S. Military Aircraft and for Missile and Projectile Firings.” (10) (FCM) – The definition is taken from the DoD Foreign Clearance Manual. (11) TWO OR MORE CODES – The term is defined the same way in each of the documents indicated. ABBREVIATED IFR FLIGHT PLANS - An authorization by Air Traffic Control requiring pilots to submit only that information needed for the purpose of Air Traffic Control. It includes only a small portion of the usual IFR flight plan information. In certain instances, this may be only aircraft identification, location, and pilot request. Other information may be requested if needed by Air Traffic Control for separation/control purposes. It is frequently used by aircraft which are airborne, desire an instrument approach, or by aircraft on the ground which desire a climb to VFR on top. (See VFR-on-top). ABEAM - An aircraft is "abeam" a fix, point or object when that fix, point or object is approximately 90 degrees to the right or left of the aircraft track. Abeam indicates a general position rather than a precise point. ABORT (P/CG) - To terminate a preplanned aircraft maneuver; e.g., an aborted take-off. ABORT (JCS, NATO) - (1) Failure to accomplish a mission for any reason other than enemy action. It may occur at any point from initiation of operation to destination. (2) Discontinue aircraft take-off run or launch. ACCELERATE-STOP DISTANCE AVAILABLE (ICAO) - The length of the take-off run available plus the length of the stopway if provided. ACKNOWLEDGE - Let me know that you have received my message. ACKNOWLEDGE (ICAO) - Let me know that you have received and understand this message. ACROBATIC FLIGHT (P/CG) - An intentional maneuver involving an abrupt change in an aircraft's attitude, an abnormal attitude, or abnormal acceleration, not necessary for normal flight. (Refer to Federal Air Regulations Part 91) ACROBATIC FLIGHT (ICAO) - Maneuvers intentionally performed by an aircraft involving an abrupt change in its attitude, an abnormal attitude or abnormal variation in speed. ADDITIONAL SERVICES - Advisory information provided by Air Traffic Control which includes but is not limited to the following: (1) Traffic advisories. (2) Vectors, when requested by the pilot, to assist aircraft receiving traffic advisories to avoid observed traffic. (3) Altitude deviation information of 300 feet or more from an assigned altitude as observed on a verified (reading correctly) automatic altitude readout (Mode C). (4) Advisories that traffic is no longer a factor. (5) Weather and chaff information. (6) Weather assistance. (7) Bird activity information. (8) Holding pattern surveillance. Additional services are provided to the extent possible contingent only upon the controller's capability to fit them into the performance of higher priority duties and on the basis of limitations of the radar, volume of traffic, frequency congestion and controller workload. The controller has complete discretion for determining if he is able to provide or continue to provide a service in a particular case. The controller's reason not to provide or continue to provide a service in a particular case is not subject to question by the pilot and need not be made known to him. (See Traffic Advisories) ADMINISTRATOR - The Federal Aviation Administrator or any person to whom he has delegated his authority in the matter concerned. 2-2 TERMS ADVISE INTENTIONS - Tell me what you plan to do. ADVISORY - Advice and information provided to assist pilot in the safe conduct of flight and aircraft movement. (See Advisory Service) ADVISORY AREA (JCS, NATO, ICAO) - A designated area within a Flight Information Region where Air Traffic Advisory Service is available. ADVISORY FREQUENCY - The appropriate frequency to be used for Airport Advisory Service. (See Airport Advisory Service and UNICOM) (Refer to Advisory Circular No. 90-42) ADVISORY ROUTE/ADR (ICAO) - A route within a Flight Information Region along which Air Traffic Advisory Service is available. NOTE: Air Traffic Control service provides a much more complete service than Air Traffic Advisory Service; Advisory Areas and Routes are therefore not established within controlled airspace, but Air Traffic Advisory Service may be provided below and above Control Areas. ADVISORY SERVICE - Advice and information provided by a facility to assist pilots in the safe conduct of flight and aircraft movement. (See Airport Advisory Service, Traffic Advisories, Safety Alerts, Additional Services, Radar Advisory, Enroute Flight Advisory Service) AERIAL REFUELING/INFLIGHT REFUELING - A procedure used by the military to transfer fuel from one aircraft to another during flight. AERODROME (ICAO) - A defined area on land or water (including any buildings, installations and equipment) intended to be used either wholly or in part for the arrival, departure and movement of aircraft. NOTE: The term "aerodrome" where used in the provisions relating to flight plans and Air Traffic Service messages is intended to cover also sites other than aerodromes which may be used by certain types of aircraft, e.g. helicopters or balloons. AERODROME BEACON (ICAO) - Aeronautical beacon used to indicate the location of an aerodrome from the air. AERODROME CONTROL SERVICE (ICAO) - Air traffic control service for aerodrome traffic. AERODROME CONTROL TOWER (ICAO) - A unit established to provide air traffic control service to aerodrome traffic. AERODROME ELEVATION (ICAO) - The elevation of the highest point of the landing area. AERODROME TRAFFIC CIRCUIT (ICAO) - The specified path to be flown by aircraft operating in the vicinity of an aerodrome. AERONAUTICAL BEACON - A visual navigational aid displaying flashes of white and/or colored light to indicate the location of an airport, a heliport, a landmark, a certain point of a Federal airway in mountainous terrain, or an obstruction. (See Airport Rotating Beacon) AERONAUTICAL CHART (P/CG) - A map used in air navigation containing all or part of the following: Topographic features, hazards and obstructions, navigational aids, navigation routes, designated airspace, and airports. (1) See GENERAL PLANNING for a description of the Flight Information Publication Programs. (2) See the DLA Catalog of Maps, Charts and Related Products available via CD-ROM or online at DoD EMALL, (https://dod.emall.dla.mil/), for descriptions and availability of visual navigation charts. AERONAUTICAL CHART (ICAO) - A representation of a portion of the earth, its culture and relief, specifically designated to meet the requirements of air navigation. AERONAUTICAL INFORMATION MANUAL/AIM - A primary Federal Aviation Administration publication whose purposes is to instruct airmen about operating in the National Airspace System of the United States. It provides basic flight information, Air Traffic Control procedures and general instructional information concerning health, medical facts, factors affecting flight safety, accident and hazard reporting, and types of aeronautical charts and their use. AERONAUTICAL INFORMATION PUBLICATION (ICAO) - A publication issued by or with the authority of a state and containing aeronautical information of a lasting character essential to air navigation. AFFIRMATIVE - Yes. AIRBORNE DELAY - Amount of delay to be encountered in airborne holding. AIR CARRIER DISTRICT OFFICE/ACDO - A Federal Aviation Administration field office serving an assigned geographical area, staffed with Flight Standards personnel serving the aviation industry and the general public, on matters related to the certification and operation of scheduled air carriers and other large aircraft operations. AIRCRAFT (P/CG) - Device/s that are used or intended to be used for flight in the air and when used in Air Traffic Control terminology may include the flight crew. AIRCRAFT (ICAO) - Any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth's surface. AIRCRAFT APPROACH CATEGORY (P/CG) - A grouping of aircraft based on a speed of 1.3 times the stall speed in the landing configuration at maximum gross landing weight. An aircraft shall fit in only one category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the next higher category should be used. For example, an aircraft which falls in category A, but is circling to land at a speed in excess of 90 knots, should use the approach category B minimums when circling to land. The categories are as follows:) (1) CATEGORY A - Speed less than 91 knots. (2) CATEGORY B - Speed 91 knots or more but less than 121 knots. (3) CATEGORY C - Speed 121 knots or more but less than 141 knots. (4) CATEGORY D - Speed 141 knots or more but less than 166 knots. (5) CATEGORY E - Speed 166 knots or more. (Refer to Code of Federal Regulations Parts 1 and 97) TERMS 2-3 AIRCRAFT APPROACH CATEGORY DoD (USAF) - The five approach categories (A thru E) are based on 1.3 times the stall speed in the landing configuration.

(7) VISUAL GLIDE SLOPE INDICATOR/VGSI (USAF) - Ground device that uses colored lights to define a vertical approach path during the final approach to a runway. Vegas use not less than two and not more than four colors. Color sectors are distinct and identifiable throughout the horizontal beam width at all intensity settings. Allowable colors are red, yellow, green, or white. Red is used to indicate the lowest below approach path sector. The display area for a VGSI is ten degrees either side of the extended runway centering beginning from the light or light bar farthest from the threshold and ending at a point four miles from the threshold. Vegas are aligned to provide TERMS 2-5 a minimum of a one degree glide path over obstacles within the display area. Lateral guidance to the runway centering is obtained by reference to either visual cues or electronic aids. (a) VISUAL APPROACH SLOPE INDICATOR/VASI - This VGSI system provides vertical visual approach slope guidance to aircraft during approach to landing by radiating a directional pattern of high intensity red and white focused light beams which indicate to the pilot that he is "on path" if he sees red/white, "above path" if white/white, and "below path" if red/red. Some airports serving large aircraft have three-bar VASI which provide two visual glide paths to the same runway. See FIH Section B for further system details. 1 NONCOINCIDENT VASI SYSTEMS - These VASI systems have a Glide Slope Angle and/or Runway Point of Intercept which differs from the Precision Approach Radar or the radio navigation precision approach system (Instrument Landing System or Microwave Landing System). Noncoincident VASI systems will be reported in the Enroute Supplement under "Service". 2 NONSTANDARD VASI SYSTEMS - Nonstandard VASI systems may consist of varying approach light configurations such as T-VASIs or Tri-color VASIs. Although nonstandard, they provide the same visual descent guidance as the two or three light bar VASI systems. 3 LOW COST VASI/LCVASI - This VGSI system consists of three sets of four white lights on three mounts, usually installed on only one side of the runway. LCVASI indicates only above, on, or below the glide path and does not indicate the magnitude of any deviation. See FIH Section B for further system details. (b) PRECISION APPROACH PATH INDICATOR/PAPI - This VGSI system consists of four light boxes, similar to the standard VASI light boxes, installed in a horizontal row on one side of the runway, usually the left side. When on glide path, the pilot will see two red lights and two white lights. When the aircraft deviates from the normal glide path, the combination of red and white lights change. At some locations, light boxes may be installed on both sides of the runway. This does not affect the system operation. (c) PULSATING VISUAL APPROACH SLOPE INDICATOR / PVASI - This VGSI system normally consists of a single light unit projecting a two-color visual approach path. The on glide path indication is a steady white light, the above glide path indication is a pulsating white light, the below glide path indication is a pulsating red light with a slightly below glide path indication of a solid red light. As the deviation above or below the glide path increases, the duration of the pulses (white or red) decreases and reaches zero at the upper edge of the viewing range of the system. The useful range of this system is approximately 4 miles during the day and up to 10 miles at night. (8) BOUNDARY LIGHTS - Lights defining the perimeter of an airport or landing area. (9) RAPID EXIT TAXIWAY INDICATOR LIGHTS/RETIL - Consist of a group of yellow lights in a 3-2-1 sequence spaced 328 ft apart to a rapid exit taxiway.

(2) White and yellow-lighted water airport. (3) Green, yellow, and white-lighted heliport. The number of flashes per minute from beacons identifying heliports is usually greater than the number of flashes per minute from beacons identifying airports. Military airport beacons flash alternately white and green, but are differentiated from civil airport beacons by dual peaked (two quick) white flashes between the green flashes. AIRPORT SURFACE DETECTION EQUIPMENT/ASDE - Radar equipment specifically designed to detect all principal features on the surface of an airport, including aircraft and vehicular traffic and to present the entire image on a radar indicator console in the control tower.
