31.5 Pilots should be especially vigilant when
conducting “position and hold” operations at night or
during reduced visibility conditions. They should
scan the full length of the runway and look for aircraft
on final approach or landing roll out when taxiing
onto a runway. ATC should be contacted anytime
there is a concern about a potential conflict.
31.6 When two or more runways are active, aircraft
may be instructed to “POSITION AND HOLD” on
two or more runways. When multiple runway
operations are being conducted, it is important to
listen closely for your call sign and runway. Be alert
for similar sounding call signs and acknowledge all
instructions with your call sign. When you are
holding in position and are not sure if the takeoff
clearance was for you, ask ATC before you begin
takeoff roll. ATC prefers that you confirm a takeoff
clearance rather than mistake another aircraft’s
clearance for your own.
31.7 When ATC issues intersection “position and
hold” and takeoff clearances, the intersection
designator will be used. If ATC omits the intersection
designator, call ATC for clarification.
EXAMPLE−
Aircraft: “Cherokee 234AR, Runway 24L at November 4,
position and hold.”
31.8 If landing traffic is a factor during position and
hold operations, ATC will inform the aircraft in
position of the closest traffic that has requested a full−
stop, touch−and−go, stop−and−go, or an unrestricted
low approach to the same runway. Pilots should take
care to note the position of landing traffic. ATC will
also advise the landing traffic when an aircraft is
authorized to “position and hold” on the same
runway.
EXAMPLE−
Tower: “Cessna 234AR, Runway 24L, position and hold.
Traffic a Boeing 737, six mile final.”
Tower: “Delta 1011, continue, traffic a Cessna 210
position and hold Runway 24L.”
NOTE−
ATC will normally withhold landing clearance to arrival
aircraft when another aircraft is in position and holding on
the runway.
31.9 Never land on a runway that is occupied by
another aircraft, even if a landing clearance was
issued. Do not hesitate to ask the controller about the
traffic on the runway and be prepared to execute a go−
around.
NOTE−
Always clarify any misunderstanding or confusion
concerning ATC instructions or clearances. ATC should be
advised immediately if there is any uncertainty about the
ability to comply with any of their instructions.
32. Departure Restrictions, Clearance Void
Times, Hold for Release, and Release Times
32.1 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.

32.1.1 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 his or her
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
14 CFR Section 91.173 which requires that pilots receive
an appropriate ATC clearance before operating IFR in
Class A, B, C, D, and E airspace.
EXAMPLE−
Clearance 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.
32.1.2 Hold for Release. ATC may issue “hold for
release” instructions in a clearance to delay an aircrafts
departure for traffic management reasons (i.e.,
