ing under VFR. However, prior to takeoff the pilot
should cancel the IFR flight plan and operate the
transponder on the appropriate VFR code. An IFR
clearance may not be available after departure.
(Aircraft identification) cleared to (destination) airport as
filed, maintain (altitude), and, if required (additional in-
structions or information), hold for release, expect (time in
hours and/or minutes) departure delay.
3. Release Times. A "release time" is a depar-
ture restriction issued to a pilot by ATC, specifying
the earliest time an aircraft may depart. ATC will use
"release times" in conjunction with traffic manage-
ment procedures and/or to separate a departing
aircraft from other traffic.
(Aircraft identification) released for departure at (time in
hours and/or minutes).
4. Expect Departure Clearance Time
(EDCT). The EDCT is the runway release time
assigned to an aircraft included in traffic management
programs. Aircraft are expected to depart no earlier
than 5 minutes before, and no later than 5 minutes af-
ter the EDCT.
b. If practical, pilots departing uncontrolled air-
ports should obtain IFR clearances prior to becoming
airborne when two-way communications with the
controlling ATC facility is available.
5-2-7. Departure Control
a. Departure Control is an approach control func-
tion responsible for ensuring separation between
departures. So as to expedite the handling of depar-
tures, Departure Control may suggest a takeoff
direction other than that which may normally have
been used under VFR handling. Many times it is pre-
ferred to offer the pilot a runway that will require the
fewest turns after takeoff to place the pilot on course
or selected departure route as quickly as possible. At
many locations particular attention is paid to the use
of preferential runways for local noise abatement pro-
grams, and route departures away from congested
b. Departure Control utilizing radar will normally
clear aircraft out of the terminal area using DPs via ra-
dio navigation aids.
1. When a departure is to be vectored immedi-
ately following takeoff, the pilot will be advised prior
to takeoff of the initial heading to be flown but may
not be advised of the purpose of the heading.
2. At some airports when a departure will fly an
RNAV SID that begins at the runway, ATC may ad-
vise aircraft of the initial fix/waypoint on the RNAV
route. The purpose of the advisory is to remind pilots
to verify the correct procedure is programmed in the
FMS before takeoff. Pilots must immediately advise
ATC if a different RNAV SID is entered in the air-
craft's FMC. When this advisory is absent, pilots are
still required to fly the assigned SID as published.

a vector to the initial waypoint are assigned a heading be-
3. Pilots operating in a radar environment are
expected to associate departure headings or an RNAV
departure advisory with vectors or the flight path to
their planned route or flight. When given a vector tak-
ing the aircraft off a previously assigned nonradar
route, the pilot will be advised briefly what the vector
is to achieve. Thereafter, radar service will be pro-
vided until the aircraft has been reestablished
"on-course" using an appropriate navigation aid and
the pilot has been advised of the aircraft's position or
a handoff is made to another radar controller with fur-
ther surveillance capabilities.
c. Controllers will inform pilots of the departure
control frequencies and, if appropriate, the transpon-
der code before takeoff. Pilots must ensure their
transponder is adjusted to the "on" or normal operat-
ing position as soon as practical and remain on during
all operations unless otherwise requested to change to
"standby" by ATC. Pilots should not change to the de-
parture control frequency until requested. Controllers
may omit the departure control frequency if a DP has
or will be assigned and the departure control fre-
quency is published on the DP.
