A330 TT AUTO XTER FAIL

[maremare505]

For those on the know...
Why is it that on the A330 TT Fuel Systems and as per the FCOM 1 reads: if one needs to gravity feed (forward) the fuel from the TT, (AUTO TT Fuel Transfer Fail), there may be a possibility the APU may flame out? Can the A330-200 APU get its FUEL from the L inner, Trim Pipe or the TT itself?

Thanks

A330 and A343 apu fuel feed is the trim tank pipe , so can cause apu auto-shutdown with low fuel pressure in trim line. Still some 343's about that can't keep the apu running whilst refuelling trim tank !
