ICAO: 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.
Fr: performance ascensionnelle en route
en route descent
Descent from the en route cruising altitude.
Fr: descente en route
en route flight advisory service U.S.: 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.
. also called: flight watch
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 (CTA). Fr: repère d’entrée
EOBT ICAO and U.S.: Abbreviation for: estimated off-block time
ESCAT Plan Abbreviation for: Emergency Security Control of Air Traffic Plan Fr: plan ESCAT
established holding area
A holding area that has been predetermined by the unit responsible for the airspace concerned.
Fr: zone d’attente établie
estimate Canada: 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. Fr: estimée
“Estimated . . . ” Canada: An expression used within ATS when communicating an ATC estimate. Note: This expression is used in conjunction with a place and a time. Fr: . Estimé... .
estimated elapsed time
The estimated time required to proceed from one significant point to another.
. abbreviation: EET
Fr: durée estimée
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. Fr: heure d’atterrissage prévue
estimated off-block time
The estimated time at which the aircraft will commence movement associated with departure.
Fr: heure estimée de départ du poste de stationnement
estimated time en route
U.S.: The estimated flying time from departure point to destination (liftoff to touchdown).
. abbreviation: ETE
estimated time of arrival
(1) 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.
. abbreviation: ETA
Fr: heure d’arrivée prévue
(2) ICAO: 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.
