A 320 Electrical Question
 

If any A320 professional could illuminate: If APU is inoperative and you follow the starting procedure in FCOM 3, Engine Start with Pneumatic Power, which means starting ENG 2 first, why does the IFE (Passenger Demo) system shut down at the power transient when ENG 2 GEN comes online and EXT PWR is removed?:confused:

Any explanation


Thanks

Loadshedding of the galley.

It doesn't matter what engine is started first.

To keep the galley powered on ground, you need both aircraft genes or either GPU or APU. In the air, it takes power from two generators to hold the main galley relay closed.
