Departure Procedures
instructed to line up and wait and has been advised of
a reason/condition (wake turbulence, traffic on an
intersecting runway, etc.) or the reason/condition is
clearly visible (another aircraft that has landed on or
is taking off on the same runway), and the reason/
condition is satisfied, the pilot should expect an
imminent takeoff clearance, unless advised of a
delay. If you are uncertain about any ATC instruction
or clearance, contact ATC immediately.
c.
If a takeoff clearance is not received within a
reasonable amount of time after clearance to line up
and wait, ATC should be contacted.
EXAMPLE
−
Aircraft: Cessna 234AR holding in position Runway 24L.
Aircraft: Cessna 234AR holding in position Runway 24L
at Bravo.
NOTE
−
FAA analysis of accidents and incidents involving aircraft
holding in position indicate that two minutes or more
elapsed between the time the instruction was issued to line
up and wait and the resulting event (for example, land
−over
or go
−around). Pilots should consider the length of time
that they have been holding in position whenever they
HAVE NOT been advised of any expected delay to
determine when it is appropriate to query the controller.

Flightcrew Procedures during Taxi Operations
d.
Situational awareness during line up and wait
operations is enhanced by monitoring ATC
instructions/clearances issued to other aircraft. Pilots
should listen carefully if another aircraft is on
frequency that has a similar call sign and pay close
attention to communications between ATC and other
aircraft. If you are uncertain of an ATC instruction or
clearance, query ATC immediately. Care should be
taken to not inadvertently execute a clearance/
instruction for another aircraft.
e.
Pilots should be especially vigilant when
conducting line up and wait 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.
f.
When two or more runways are active, aircraft
may be instructed to “LINE UP AND WAIT” 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.
g.
When ATC issues intersection “line up and
wait” 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,
line up and wait.”
h.
If landing traffic is a factor during line up and
wait 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 “line up and wait” on the same runway.
EXAMPLE
−
Tower: “Cessna 234AR, Runway 24L, line up and wait.
Traffic a Boeing 737, six mile final.”
Tower: “Delta 1011, continue, traffic a Cessna 210
holding in position Runway 24L.”
NOTE
−
ATC will normally withhold landing clearance to arrival
aircraft when another aircraft is in position and holding on
the runway.
i.
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.

5. Abbreviated IFR Departure Clear-
ance (Cleared. . .as Filed) Procedures
a.
ATC facilities will issue an abbreviated IFR de-
parture clearance based on the ROUTE of flight filed
in the IFR flight plan, provided the filed route can be
approved with little or no revision. These abbreviated
clearance procedures are based on the following
conditions:
