Re: Multiple external power switches

Not having flown an Airbus wide-body, I can't comment on their philosophy. But, Boeing generally has several busses that can power the aircraft. There is the normal AC power bus which when powered will power the entire aircraft. There is also the service bus which allows the aircraft to be powered i...

IIRC, they do share the same exhaust duct, although it is larger in diameter. I think they are mounded in a modified APU area in the tail where they are mounted one after another on the centerline.
