REFERENCE-
FAAO 7110.65, OVERDUE AIRCRAFT, Para 10-3-1.
FAAO 7110.65, TRAFFIC RESTRICTIONS, Para 10-4-1.

TIME (time in hours, minutes, and the nearest quarter minute).
b. Hold For Release (HFR).
1. "Hold for release" instructions shall be used when necessary to inform a pilot or a controller that a departure clearance is not valid until additional instructions are received.

2. When issuing hold for release instructions, include departure delay information.
PHRASEOLOGY-
(Aircraft identification) CLEARED TO (destination) AIRPORT AS FILED, MAINTAIN (altitude),
and if required,

HOLD FOR RELEASE, EXPECT (time in hours and/or minutes) DEPARTURE DELAY.
3. When conditions allow, release the aircraft as soon as possible.
PHRASEOLOGY-

c. Release Times.
1. Release times shall be issued to pilots when necessary to specify the earliest time an aircraft may depart.
NOTE-
A release time is a departure restriction issued to a pilot (either directly or through authorized relay) to separate a departing aircraft from other traffic.
2. The facility issuing a release time to a pilot shall include a time check.

TIME (time in hours, minutes, and nearest quarter minute).
d. When controlled departure time (CDT) procedures are in effect, the departure terminal shall, to the extent possible, plan ground movement of aircraft destined to the affected airport(s) so that flights are sequenced to depart as near as possible to the assigned EDCT, but no earlier than 5 minutes prior to the EDCT or 15 minutes after the assigned EDCT. If the aircraft is unable to meet these parameters, contact the overlying TMU for a revised EDCT.
