A320 APU Fuel Pump
Hello guys,
my friend and I were have a discussion about whether the APU fuel pump is a DC pump or AC pump. The electrical schematic clearly shows that it is supplied by AC Ess Bus or the Static Inv Bus, therefore it has to be an AC pump. Just need a clarification on this.
On a side note, he also believes that a PFR which contains no ECAM warning but shows a long list of Fault messages does not require any corrective maintenance action. Do you guys agree?
Thanks!
