a. ARTS IIIA. The Radar Tracking and Beacon Tracking Level (RT&BTL) of the modular, programmable automated radar terminal system. ARTS IIIA detects, tracks, and predicts primary as

well as secondary radar-derived aircraft targets. This more sophisticated computer-driven system up-grades the existing ARTS III system by providing improved tracking, continuous data recording, and fail-soft capabilities.
b.Common ARTS. Includes ARTS IIE, ARTS IIIE; and ARTS IIIE with ACD (see DTAS) which combines functionalities of the previous ARTS systems.
c.Programmable Indicator Data Processor (PIDP). The PIDP is a modification to the AN/TPX.42 interrogator system currently installed in fixed RAPCONs. The PIDP detects, tracks, and predicts secondary radar aircraft targets. These are displayed by means of computer.generated symbols and alphanumeric characters depicting flight identifi-cation, aircraft altitude, ground speed, and flight plan data. Although primary radar targets are not tracked, they are displayed coincident with the secondary radar targets as well as with the other symbols and alphanumerics. The system has the capability of interfacing with ARTCCs.
AUTOMATED WEATHER SYSTEM. Any of the automated weather sensor platforms that collect weather data at airports and disseminate the weather information via radio and/or landline. The systems currently consist of the Automated Surface Observ-ing System (ASOS), Automated Weather Sensor System (AWSS) and Automated Weather Observa-tion System (AWOS).
AUTOMATED UNICOM. Provides completely automated weather, radio check capability and airport advisory information on an Automated UNICOM system. These systems offer a variety of features, typically selectable by microphone clicks, on the UNICOM frequency. Availability will be published in the Airport/Facility Directory and approach charts.
AUTOMATIC ALTITUDE REPORT.
(See ALTITUDE READOUT.)AUTOMATIC ALTITUDE REPORTING. That function of a transponder which responds to Mode C interrogations by transmitting the aircraft’s altitude in 100-foot increments.
AUTOMATIC CARRIER LANDING SYSTEM.
U.S. Navy final approach equipment consisting of precision tracking radar coupled to a computer data link to provide continuous information to the aircraft, monitoring capability to the pilot, and a backup approach system.
PCG A.15
AUTOMATIC DEPENDENT SURVEILLANCE (ADS) [ICAO]. A surveillance technique in which aircraft automatically provide, via a data link, data derived from on.board navigation and position fixing systems, including aircraft identification, four dimensional position and additional data as appropriate.
AUTOMATIC DEPENDENT SURVEILLANCE. BROADCAST (ADS-B). A surveillance system in which an aircraft or vehicle to be detected is fitted with cooperative equipment in the form of a data link transmitter. The aircraft or vehicle periodically broadcasts its GPS.derived position and other information such as velocity over the data link, which is received by a ground.based transmitter/receiver (transceiver) for processing and display at an air traffic control facility.
(See GLOBAL POSITIONING SYSTEM.)(See GROUND.BASED TRANSCEIVER.)AUTOMATIC DEPENDENT SURVEILLANCE. CONTRACT (ADS.C). A data link position reporting system, controlled by a ground station, that establishes contracts with an aircraft’s avionics that occur automatically whenever specific events occur, or specific time intervals are reached.
AUTOMATIC DIRECTION FINDER. 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.)(See NONDIRECTIONAL BEACON.)AUTOMATIC FLIGHT INFORMATION SERVICE (AFIS) . ALASKA FSSs ONLY. The continuous broadcast of recorded non.control information at airports in Alaska where a FSS provides local airport advisory service. The AFIS broadcast automates the repetitive transmission of essential but routine information such as weather, wind, altimeter, favored runway, breaking action, airport NOTAMs, and other applicable information. The information is continuously broadcast over a discrete VHF radio frequency (usually the ASOS frequency.)AUTOMATIC TERMINAL INFORMATION SERVICE. 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 Alfa. One three zero zero Coordinated Universal Time. Weather, measured ceiling two thousand overcast, visibility three, haze, smoke, temperature seven one, dew point five seven, wind two five zero at five, altimeter two niner niner six. I-L-S Runway Two Five Left approach in use, Runway Two Five Right closed, advise you have Alfa.”
(See ICAO term AUTOMATIC TERMINAL
INFORMATION SERVICE.)(Refer to AIM.)AUTOMATIC TERMINAL INFORMATION SERVICE [ICAO]. The provision of current, routine information to arriving and departing aircraft by means of continuous and repetitive broadcasts 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.
a.Autorotative Landing/Touchdown Autorota-tion. Used by a pilot to indicate that the landing will be made without applying power to the rotor.
b.Low Level Autorotation. Commences at an altitude well below the traffic pattern, usually below 100 feet AGL and is used primarily for tactical military training.
c.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.
