Are “centre tank pump1, 2 running normally” recorded FDR parameters?
Are the centre tank push-buttons positions recorded?
Would failure of the CT pump pressure sensors be recorded?
Fuel pump switch position is recorded.
Fuel pump output pressure switch sense is recorded.
I.e. Pump switch ON or OFF command
and pressure switch Pressure or NO Pressure.
Failure of sensors is not recorded, has to be determined by logic.(not computor logic but human logic!)
