Thanks for the replys but woe a minute....
I dont see anything in FCOM or QRH that the APU batt drain is less with the EMER GEN running.
With EMERG GEN running.....
QRH 1.01 APU Elec Control Box for start/LP Fuel Valve/Fuel Pump
FCOM 1.24.10 P13 EMER GEN RUNNING diag
FCOM 1.49.30 P1 whole page
I cant see any evidance that the batt isnt drained (3.5 minutes) by a APU start while EMERG GEN running. Thats the way I always understooded it.
With referance to QRH 1.01 the list says what youve got remaining, not nesesarily what the RAT may or may not be powering.
Somethin being missed by yours truley here?
