Start Up/Pushback Procedures For Wide-Bodied Aircraft

Aircraft fitted with auxiliary power unit (AUXILIARY POWER UNIT), the following procedures shall apply :

Aircraft shall start up one engine

Pushback shall commence after one engine has started up. Such engine shall be on idle power at pushback.

Start up of all other engine shall be made after pushback and when the aircraft is positioned on the apron taxiway line.

Aircraft not fitted with auxiliary power unit (AUXILIARY POWER UNIT) or when auxiliary power unit is unserviceable, the following procedures shall apply :

Aircraft without AUXILIARY POWER UNIT shall be permitted to start all engines up before pushback.

Request by flight crew to start one engine first (due to special circumstance) and the rest after completion of pushback, shall be granted.

Start UP/PUSH Back Procedure For Turbine Aircraft

The normal procedure is for a pilot to advise AERODROME CONTROL TOWER that it is starting in 3-5 minutes ascertain that aircraft will not get delay due to traffic.

When a delay is expected, AERODROME CONTROL TOWER shall advise the pilot of the earlier time of departure.

For a wide-bodied or jumbo jet aircraft parked on Terminal ALPHA and BRAVO, AERODROME CONTROL TOWER shall issue a pushback time instead of clearance to start up.

Due to possibility of conflict in traffic, a clearance expiry time may be issued with the pushback time. A clearance shall be considered cancelled if an aircraft is unable to comply with the time so specified.

Pushback clearance shall contain the heading direction which should be followed by flight crew before commencing taxi by ending the pushback clearance with the phraseology: [C/S] PUSHBACK APPROVED HEADING NORTH (or SOUTH).

Note.— The determination of heading North or South is depend on the location of exit taxiway from apron. For example, if an aircraft is parked on main apron and the runway-in-use will be 34L/34R, heading assignment should be HEADING SOUTH.
