I know its an old loft scenario. However if you despatch under the MEL with the Bleed off fault , then you are directed in the MEL with what to do in the event of the scenario described. However , if it just happens in flight the way I described. You have to configure the bleeds from memory to get the APU to provide the packs ( Not rocket science , but stepping outside the box) . EK, EY ,QR , who cares where I am from its all the same sandbox
and it sucks.
