B744 HST Fuel pump operation
When departing with max fuel on the B744 (fitted with HST) is it the norm to already have the L and R STAB pump switches on before departure?
I am aware that the pumps won't actually run until the logic commands the feed to the CWT (CWT fuel approx. < 37,000Kgs).
So to sum it up, do you put them on from the start until the HST transfer begins automatically and is complete, or do you wait for the EICAS advisory to turn hem on so that transfer to the CWT can begin?
