DEFINITIONS
ACCELERATE STOP DISTANCE AVAILABLE
(ASDA) — The length of the take-off run available
plus the length of the stopway, if provided.
ACROBATIC FLIGHT — Manoeuvres intentionally
performed by an aircraft involving an abrupt change
in its attitude, an abnormal attitude, or an abnormal
variation in speed.
ADEQUATE VIS REF (Adequate Visual Reference)
— Runway markings or runway lighting that
provides the pilot with adequate visual reference to
continuously identify the take-off surface and maintain
directional control throughout the take-off run.
ADS AGREEMENT — An ADS reporting plan which
establishes the conditions of ADS data reporting (i.e.,
data required by the air traffic services unit and frequency
of ADS reports which have to be agreed to
prior to the provision of the ADS services).
NOTE: The terms of the agreement will be exchanged
between the ground system and the aircraft bymeans
of a contract, or a series of contracts.
ADS-C AGREEMENT — A reporting plan which
establishes the conditions of ADS-C data reporting
(i.e. data required by the air traffic services unit and
frequency of ADS-C reports which have to be agreed
to prior to using ADS-C in the provision of air traffic
services).
NOTE: The terms of the agreement will be exchanged
between the ground system and the aircraft bymeans
of a contract, or a series of contracts.
ADS CONTRACT — A means by which the terms
of an ADS agreement will be exchanged between the
ground system and the aircraft, specifying under what
conditions ADS reports would be initiated, and what
data would be contained in the reports.
NOTE: The term “ADS contract” is a generic term
meaning variously, ADS event contract, ADS demand
contract, ADS periodic contract or an emergency
mode. Ground forwarding of ADS reports may be
implemented between ground systems.
ADVISORY AIRSPACE — An airspace of defined
dimensions, or designated route, within which air traffic
advisory service is available.
ADVISORY ROUTE (ADR) — A designated route
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.
AERODROME — 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 surface movement of aircraft.
NOTE: The term “aerodrome” where used in the provisions
relating to flight plans and ATS 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 CLIMATOLOGICAL SUMMARY —
Concise summary of specified meteorological elements
at an aerodrome, based on statistical data.
AERODROME CLIMATOLOGICAL TABLE —Table
providing statistical data on the observed occurrence
of one or more meteorological elements at an aerodrome.
AERODROME CONTROL SERVICE — Air traffic
control service for aerodrome traffic.
AERODROME CONTROL TOWER — A unit established
to provide air traffic control service to aerodrome
traffic.
AERODROME ELEVATION — The elevation of the
highest point of the landing area.
AERODROME FLIGHT INFORMATION SERVICE
(AFIS) — A directed traffic information and operational
information service provided within an aerodrome
flight information zone, to all radio equipped
aircraft, to assist in the safe and efficient conduct of
flight.
AERODROME METEOROLOGICAL OFFICE — An
office, located at an aerodrome, designated to provide
meteorological service for international air navigation.
AERODROME REFERENCE CODE — A simple
method for interrelating the numerous specifications
concerning the characteristics of aerodromes so as
to provide a series of aerodromes facilities that are
suitable for the aeroplanes that are intended to operate
at the aerodrome. The aerodrome reference code
— code number and letter, which are selected for
aerodrome planning purposes
