Hi,
It may be a mistake I am making and perhaps a misunderstanding but I have a query regarding the fuel system. I am currently taxiing out to a runway at EHAM in PH-BFA and I have 93.4Kgs (x1000) on board. Tanks show:
MAIN 1; 13.3
MAIN 2; 29.4
MAIN 3; 29.4
MAIN 4; 13.3
CENTRE; 0.0
RES 1; 4.0
RES 2; 4.0
STAB; 0.0
In terms of my overhead
- FUEL X FEED (1) shows ON i.e. button pushed white bar showing.
- FUEL X FEED (2) shows ON i.e. button pushed white bar showing (guarded switch closed).
- FUEL X FEED (3) shows ON i.e. button pushed white bar showing (guarded switch closed).
- FUEL X FEED (4) shows ON i.e. button pushed white bar showing.
In terms of fuel pumps, all on (including OVRD pumps) except CTR L, CTR R, STAB L and STAB R.
My query is, on my status page for the fuel system FUEL X FEED 2 and 3 show as closed i.e. off centre, no green bar through the valve. If I then change the switches manually for X FEED 2 and 3, this has no effect. I tried to cycle these switches through OFF and ON (opening the guard etc) and no effect. I then wondered if this part of the automatics, so figured if I turned off MAIN 2 FWD and AFT pumps the valve would open as there was no fuel pumping to engine 2, but it didn't. Can someone explain this behaviour to me?
