type operation (IFR) and the name of the airport (or
fix) to which you expect clearance.
EXAMPLE-
“Washington clearance delivery (or ground control if
appropriate) American Seventy Six at gate one, IFR
LosAngeles.”
3. If the flight plan has been changed, state the
change and request a full route clearance.
EXAMPLE-
“Washington clearance delivery, American Seventy Six at
gate one. IFR San Francisco. My flight plan route has been
amended (or destination changed). Request full route
clearance.”
4. Request verification or clarification from
ATC if ANY portion of the clearance is not clearly
understood.
5. When requesting clearance for the IFR
portion of a VFR/IFR flight, request such clearance
prior to the fix where IFR operation is proposed to
commence in sufficient time to avoid delay. Use the
following phraseology:
EXAMPLE-
“Los Angeles center, Apache Six One Papa, VFR
estimating Paso Robles VOR at three two, one thousand
five hundred, request IFR to Bakersfield.”
5-2-6. Departure Restrictions, Clearance
Void Times, Hold for Release, and Release
Times
a. ATC may assign departure restrictions, clearance
void times, hold for release, and release times,
when necessary, to separate departures from other
traffic or to restrict or regulate the departure flow.
1. Clearance Void Times. A pilot may receive
a clearance, when operating from an airport without
a control tower, which contains a provision for the
clearance to be void if not airborne by a specific time.
A pilot who does not depart prior to the clearance void
time must advise ATC as soon as possible of their
intentions. ATC will normally advise the pilot of the
time allotted to notify ATC that the aircraft did not
depart prior to the clearance void time. This time
cannot exceed 30 minutes. Failure of an aircraft to
contact ATC within 30 minutes after the clearance
void time will result in the aircraft being considered
overdue and search and rescue procedures initiated.
NOTE-
1. Other IFR traffic for the airport where the clearance is
issued is suspended until the aircraft has contacted ATC or
until 30 minutes after the clearance void time or 30 minutes
after the clearance release time if no clearance void time
is issued.
2. Pilots who depart at or after their clearance void time
are not afforded IFR separation and may be in violation of
14CFR Section 91.173 which requires that pilots receive
an appropriate ATC clearance before operating IFR in
controlled airspace.
EXAMPLEClearance
void if not off by (clearance void time) and, if
required, if not off by (clearance void time) advise (facility)
not later than (time) of intentions.
2. Hold for Release. ATC may issue “hold for
release” instructions in a clearance to delay an
aircraft's departure for traffic management reasons
(i.e., weather, traffic volume, etc.). When ATC states
in the clearance, “hold for release,” the pilot may not
depart utilizing that IFR clearance until a release time
or additional instructions are issued by ATC. In
addition, ATC will include departure delay information
in conjunction with “hold for release”
instructions. The ATC instruction, “hold for release,”
applies to the IFR clearance and does not prevent the
pilot from departing 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.
EXAMPLE-
(Aircraft identification) cleared to (destination) airport as
filed, maintain (altitude), and, if required (additional
instructions or information), hold for release, expect (time
in hours and/or minutes) departure delay.
3. Release Times. A “release time” is a
departure restriction issued to a pilot by ATC,
specifying the earliest time an aircraft may depart.
ATC will use “release times” in conjunction with
traffic management procedures and/or to separate a
departing aircraft from other traffic.
EXAMPLE-
(Aircraft identification) released for departure at (time in
hours and/or minutes).
2/14/Departure Procedures 5−2−5
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 after
the EDCT.
b. If practical, pilots departing uncontrolled airports
