AUTOMATIC DEPENDENT SURVEILLANCE (ADS) - Supports automatic reporting by an aircraft Flight Management System (FMS) of aircraft position and intent information in accordance with parameters selected by ground system.
AUTOMATIC DIRECTION FINDER/ADF - An aircraft radio navigation system which senses and indicates the direction to a L/MF nondirectional radio beacon (NDB) ground transmitter. Direction is indicated to the pilot as a magnetic bearing or as a relative bearing to the longitudinal axis of the aircraft depending on the type of indicator installed in the aircraft. In certain applications, such as military, ADF operations may be based on airborne and ground transmitters in the VHF/UHF frequency spectrum. (See Bearing, Nondirectional beacon)
AUTOMATIC TERMINAL INFORMATION SERVICE/ATIS (P/CG) - The continuous broadcast of recorded noncontrol information in selected terminal areas. Its purpose is to improve controller effectiveness and to relieve frequency congestion by automating the repetitive transmission of essential but routine information, e.g., "Los Angeles Information Alpha. One three zero zero Coordinated Universal Time weather, measured ceiling 2000 overcast, visibility three, haze, smoke, temperature seven one, dewpoint five seven, wind two five zero at five, altimeter two niner niner six. Instrument Landing System Runway two five left approach in use, runway two five right closed, advise you have Alpha."
AUTOMATIC TERMINAL INFORMATION SERVICE (ICAO) - The provision of current, routine information to arriving and departing aircraft by means of continuous and repetitive broadcast throughout the day or a specified portion of the day.
AUTOROTATION - A rotorcraft flight condition in which the lifting rotor is driven entirely by action of the air when the rotorcraft is in motion.
(1)
AUTOROTATIVE LANDING/TD AUTOROTATION - Used by a pilot to indicate that he will be landing without applying power to the rotor.

(2)
LOW LEVEL AUTOROTATION - Commences at an altitude well below the traffic pattern, usually below 100 feet

above ground level and is used primarily for tactical military training.
(3) 180 DEGREES AUTOROTATION - Initiated from a downwind heading and is commenced well inside the normal traffic pattern. "Go around" may not be possible during the latter part of this maneuver.
AVIATION WEATHER SERVICE - A service provided by the National Weather Service (NWS) and Federal Aviation Administration which collects and disseminates pertinent weather information for pilots, aircraft operators and Air Traffic Control. Available aviation weather reports and forecasts are displayed at each National Weather Service office and Federal Aviation Administration Flight Service Station. (See Enroute Flight Advisory Service. Transcribed Weather Broadcasts, Weather Advisory, Pilots Automatic Telephone Weather Answering Service)
AZIMUTH, MICROWAVE LANDING SYSTEM - A magnetic bearing extending from a Microwave Landing System navigation facility.
