A320 T/O - PACKS ON APU but APU then fails
Not my area of expertise - I'm pooped from chasing around the FCOM but a student asked an instructor who turned to me and I can't definitively answer him
Question
If packs are on APU bleed during take-off and APU fails will the engine bleeds automatically kick in. I suspect not but can't be certain and then there is a restriction on using APU bleed during a contaminated t/o that is nagging me and causing me to think I might be wrong.
Can anybody please dear god put me out of my misery.
