Terms for subject Aviation (1801 entries)
en route descent Descent from the en route cruising altitude
en route flight advisory service A service specifically designed to provide, upon pilot request, timely weather information pertinent to his/her type of flight, intended route of flight, and altitude. The FSSs providing this service are listed in the Airport/Facility Directory.
en-route alternate aerodrome An aerodrome at which an aircraft would be able to land after experiencing an abnormal or emergency condition while en route
en-route climb performance The climb (or descent) performance with the aeroplane in the en-route configuration with: (a) the critical power-unit inoperative; and (b) the critical two power-unit inoperative in the case of aeroplanes having three or more power-units
end exercise point The point at which an aircraft is no longer classified as faker
engine thrust eng thrust
engine thrust eng thrust
engineered material arresting system A soft ground arrestor system, located beyond the end of the runway and centred on the extended runway centreline, that deforms under the weight of an aircraft, bringing it to a safe stop in the event of an overrun without structural damage to the aircraft or injury to its occupants
entry fix The first reporting point over which an aircraft passes or is expected to pass upon entering a flight information region (FIR) or control area
ERP Balls Eye Reference Point Balls iwona
established holding area A holding area that has been predetermined by the unit responsible for the airspace concerned
estimate The time, in UTC, at which an IFR aircraft is calculated, by either the controller, the pilot or through automated means, to arrive over a significant point
estimated departure time The estimated time at which an aircraft will become airborne
estimated elapsed time The estimated time required to proceed from one significant point to another
estimated landing time An aircraft’s threshold-crossing estimate based on the addition of a control estimate for the metering fix and the predetermined time required to traverse a standard projected flight path from the metering fix to the threshold
estimated off-block time The estimated time at which the aircraft will commence movement associated with departure
estimated time en route The estimated flying time from departure point to destination
estimated time of arrival The time at which it is estimated that the aircraft will land, provided that no delay is experienced. Calculation of the ETA in the case of an IFR flight to an aerodrome served by one or more NAVAIDs is based on the average time required by the aircraft to complete an instrument approach procedure (IAP) at the aerodrome.
estimated time of arrival For IFR flights, the time at which it is estimated that the aircraft will arrive over that designated point, defined by reference to navigation aids, from which it is intended that an instrument approach procedure will be commenced, or, if no navigation aid is associated with the aerodrome, the time at which the aircraft will arrive over the aerodrome. For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.
estimated time of departure The estimated time at which an aircraft will become airborne
