B737CL fuel pump for APU ops
Dear all,
I had a discussion today about using of fuel pump while the APU is started. Some of the guys in company think it should be AFT 1, some FWD 1 and some that it can be even the AFT 2 or FWD 2 or any CTR (it's true if the crossfeed valve is open). Well, I have no arguments but I guess it should be the AFT 1.
What do YOU think, which one it should be? Thanks for reply in advance.
Cheers!
