Hi Dave - the apu could only be used for pneumatics in flight never electrics. I am happily retired in Glenrothes - we have rental properties and have just acquired a powder coating company - if you curb your alloy wheels come and see us!

if memory serves me on the classics the apu can only supply the tie busses inflight if they were suppying it before TO if after TO it will not be able to supply the tie bus due to ground shift. Not sure on 400's

My old company had experienced a loss of all generators on one of their B-727s about 30 years ago.
Turned out that the airplane's Constant Speed Drives coupled to the generators were mistakenly ground serviced with Skydrol by a mechanic fresh out of school . . . . All 3 CSDs had seized about 30 minutes into the flight, but luckily this occurred during day VFR.
Perhaps history repeating itself?

If you can get the APU started, it will supply power for the a/c through bus #4
