aerobatic manoeuvre	A manoeuvre where a change in the attitude of an aircraft results in a bank angle greater than 60°, an abnormal attitude or an abnormal acceleration not incidental to normal flying
aerobatic manoeuvre	A manoeuvre intentionally performed by an aircraft involving an abrupt change in altitude, an abnormal attitude or an abnormal variation in speed or flight path
aerodrome	Any area of land, water (including the frozen surface thereof) or other supporting surface used, designed, prepared, equipped or set apart for use, either in whole or in part, for the arrival, departure, movement or servicing of aircraft.

aerodrome elevation	The elevation of the highest point of the landing area
aerodrome geometric centre	The centre of the runway complex that locates the aerodrome for charting purposes, determined by calculating the mean of the latitudes of the northernmost runway threshold and the southernmost runway threshold, and the mean of the longitudes of the easternmost runway threshold and the westernmost runway threshold
aerodrome geometric centre coordinates	The latitude and longitude, to the nearest second, of the aerodrome geometric centre
aerodrome operator	The person in charge of an aerodrome, including an employee, agent or other authorized representative of that person

aerodrome traffic circuit	The specified path to be flown by aircraft operating in the vicinity of an aerodrome
aerodrome traffic frequency	A very high frequency (VHF) designated to ensure that all radio-equipped aircraft operating on the ground or within the specified ATF area are listening on a common frequency and following a common reporting procedure
aeronautical beacon	An aeronautical light arranged, either through optical design or mechanical motion, to be visible to all azimuths, either continuously or consecutively, to designate a particular point on the surface of the earth
aeronautical chart	A representation of a portion of the earth, its culture and relief, specifically designated to meet the requirements of air navigation
aeronautical fixed telecommunications network	The integrated worldwide system of aeronautical fixed circuits provided, as part of the aeronautical fixed service, for the exchange of messages between the aeronautical fixed stations within the network
