GATE DEPARTURE PROCEDURES
GENERAL
Approximately five minutes prior to departure, the ground crew will coordinate
the proposed engine start time with the flight crew. At this time, the parking
brake should be set and wheel chocks removed. The headset operator is
responsible for verifying that all personnel are clear of the aircraft. In addition,
he will check that all doors and service panels are properly closed and that the
wing tip markers (if installed) are removed. The headset operator should then
state: “WALKAROUND COMPLETE. ALL DOORS AND ACCESS
PANELS SECURE.” The headset operator should also state “READY FOR
PUSHBACK” or “CLEARED FOR ENGINE START.” If headset
communication is not available, a person to person contact must be made with
the person in charge of the ground crew.
PUSH BACK GATE
After tow tractor and tow bar have been connected and clearance obtained, give
push-out signal to tractor operator. Headset operator must accompany tractor
and aircraft during push-out to observe for possible safety hazards. Tractor
operator is responsible to observe headset operator and aircraft for signals or
possible safety hazards. After tractor and tow bar are clear of aircraft, proceed
as described in the Taxi-Out Gate procedure.
PUSH BACK / TOW OUT PROCEDURE
Note: Powerback procedures are not authorized.
This procedure is required when the aircraft is to be pushed back or towed away
from the terminal or loading area. Flight interphone contact with ground crew
must be established. If flight interphone is not available, engine start is not
authorized until pushback / tow out procedure is complete and tow bar has been
disconnected.
WARNING: Do not move the nose gear steering until towing operations
are complete and the ground crew report has been received.
Pushback With Nose Gear Lockout Pin Installed
Note: Pushback or tow out may be accomplished with hydraulic system A
pressurized if the nose gear steering lockout pin is installed.
When Cleared for Pushback / Tow Out:
· Release the brakes
Sec. 3 Page 74 737
Rev. 11/15/02 #41 Continental Flight Manual
When Aircraft is Stopped (On Signal From Ground):
· Set the parking brake
· Have the tow bar disconnected
· Obtain verification from the ground crew that the tug and tow bar are
clear and the nose gear steering lockout pin has been removed
· Clear the headset operator.
TAXI-OUT
The headset operator shall position himself between the aircraft and the terminal
building in full view of the flight deck once the headset is removed. Depending
on the direction of aircraft movement, this could be on the left or right side of
the aircraft.
After the towbar and tug have been disconnected and the flight deck is ready for
ground guidance to begin, the Captain will flash the nose gear light one time.
The final marshaller must ensure that the area is clear of any moving traffic or
other impediments to a safe taxi and then guide the aircraft until it is clear to taxi
unassisted. During ground guidance, the final marshaller must remain visible to
the flight crew.
When the ground marshaller determines that the flight deck crew no longer
requires ground guidance, the “End of Ground Clearance” hand signal will be
given. This is followed by the “Clear to Depart” (clear to taxi) salute. The
Captain should acknowledge with a salute during the day or one flash of the taxi
light at night.
Note: Three flashes of the taxi light indicates that the flight deck crew would
like to re-establish headset communication.
Note: The aircraft will not be taxied away from a gate (or pushback
position), unless the marshaller gives the crew the proper signal that
the aircraft is cleared to taxi. Should, for some reason, the marshaller
not be visible, or leave his position on the ramp, the aircraft will not
taxi. Call the station on company radio and have the marshaller return
and give taxi clearance.
Note: The headset operator is responsible to ensure the aircraft, personnel,
and equipment are clear from injury or damage from jet blast before
taxi-out signals are given aircraft. High lift trucks at gates immediately
behind must be lowered before aircraft taxis out.
