Hi MD,
Any references for that ? In my outfit we operate 1 pack on ground with APU running for fuel saving, but I have never seen any figures on how much we do actually save.
Another question regarding reduced engine taxi : when we taxi out single engine we open the crossbleed to feed both packs, but when we taxi in single engine we leave it on AUTO. Logically if it saves fuel/improves comfort running 2 packs then it should be the same during taxi in. Any thoughts ?
Cheers.
