ESTIMATED ELAPSED TIME [ICAO]- The
estimated time required to proceed from one
significant point to another.
(See ICAO Term TOTAL ESTIMATED ELAPSED
ESTIMATED OFF-BLOCK TIME [ICAO]- The
estimated time at which the aircraft will commence
movement associated with departure.
ESTIMATED POSITION ERROR (EPE)-
(See Required Navigation Performance)
ESTIMATED TIME OF ARRIVAL- The time the
flight is estimated to arrive at the gate (scheduled
operators) or the actual runway on times for
ESTIMATED TIME EN ROUTE- The estimated
flying time from departure point to destination
(lift-off to touchdown).
(See ESTIMATED TIME OF ARRIVAL.)
(See ESTIMATED TIME EN ROUTE.)
EXECUTE MISSED APPROACH- Instructions
issued to a pilot making an instrument approach
which means continue inbound to the missed
approach point and execute the missed approach
procedure as described on the Instrument Approach
Procedure Chart or as previously assigned by ATC.
The pilot may climb immediately to the altitude
specified in the missed approach procedure upon
making a missed approach. No turns should be
initiated prior to reaching the missed approach point.
When conducting an ASR or PAR approach, execute
the assigned missed approach procedure immediately
upon receiving instructions to "execute missed
(Refer to AIM.)
EXPECT (ALTITUDE) AT (TIME) or (FIX)- Used
under certain conditions to provide a pilot with an
altitude to be used in the event of two-way
communications failure. It also provides altitude
information to assist the pilot in planning.
(Refer to AIM.)
EXPECT DEPARTURE CLEARANCE TIME
(EDCT)- The runway release time assigned to an
aircraft in a traffic management program and shown
on the flight progress strip as an EDCT.
(See GROUND DELAY PROGRAM.)
EXPECT FURTHER CLEARANCE (TIME)- The
time a pilot can expect to receive clearance beyond a
EXPECT FURTHER CLEARANCE VIA (AIR-
WAYS, ROUTES OR FIXES)- Used to inform a
pilot of the routing he/she can expect if any part of the
route beyond a short range clearance limit differs
from that filed.
EXPEDITE- Used by ATC when prompt com-
pliance is required to avoid the development of an
imminent situation. Expedite climb/descent normal-
ly indicates to a pilot that the approximate best rate
of climb/descent should be used without requiring an
exceptional change in aircraft handling characteris-
