A320 Fuel Transfer Valves
Please can anyone technical help with this one?
I was led to believe that the A320 Fuel Transfer Valves were energised closed and 'relaxed' open in case of DC2 failure, but this appears from the FCOM not to be the case. There are 2 "Fuel Txfr" Cbs on 49VU. If all else fails, would pulling these CBs allow the Txfr Valves to open?
I have looked at the AMM but find it almost incomprehensible to a mere pilot.
Cheers
