Aerodrome Flight Information Service
A service provided for the purpose of giving advice and information useful for the safe and efficient conduct of flights in the vicinity of the aerodrome
Aerodrome traffic
All traffic on the maneuvering area of an aerodrome and all aircraft in flight in the vicinity of an aerodrome

Air traffic control service
A service provided for the purposes of preventing collisions between aircraft, between aircraft and obstructions on any maneuvering area, and expediting and maintaining a safe and efficient flow of air traffic.
Air traffic control unit
A unit for providing any air traffic control service and includes either an area control centre, and approach control office, or an aerodrome control tower.
Alerting service
An air traffic service provided to notify appropriate organisations regarding aircraft in need of search and rescue aid, and to assist such organisations as required.
Alternate aerodrome
An aerodrome to which an aircraft may proceed when it becomes either impossible or inadvisable to proceed to or land at, the aerodrome of intended landing.
Altitude
The vertical distance of a level, a point, or an object considered as a point, measured from mean sea level.
Approach control office
A unit established to provide ATC service to controlled flights arriving at, or departing from, one or more aerodromes
Approach control service
An air traffic control service for arriving or departing controlled flights
Area control centre
A unit established to provide ATC service to controlled flights in control areas under its jurisdiction
Area control service

Area Navigation
A method of navigation which permits aircraft operation on any desired flight path within the coverage of ground or space-based navigation systems or within the limits of the capability of self-contained navigation systems, or a combination of these.

Automatic Dependent Surveillance - Broadcast
Automatic transmission/reception of data such as identification, position and additional data in a broadcast mode via data link
baro-VNAV (Barometric vertical navigation)
A navigation system that presents to the pilot computed vertical guidance referenced to a specified vertical path angle (VPA), nominally 3 degrees. The computer-resolved vertical guidance is based on barometric altitude and is specified as a vertical path angle from RDH (Reference Datum Height).
