AUTOMATIC ENGINE START
Applicable to:
Use the automatic engine start procedure in most circumstances. However, if the start aborts due
to insufficient starter inlet air pressure (e.g. on high airfields, or in case of low pressure from an
external pneumatic power group), it is recommended to use the manual start procedure, instead the
automatic procedure.
If, during the engine start, the ground crew reports a fuel leak from the engine drain mast, run the
engine at idle for 5 min. If the leak disappears during these 5 min, the aircraft can be dispatched
without maintenance action. If the leak is still present after 5 min, maintenance action may be
required before the flight.

of ECAM DUs), abort the start by switching OFF the ENG 2 MASTER sw. Then, perform a 30 s
dry crank.
