A320 Crossbleed OPEN after engine start
In the FCOM, it states that after engine 1 start is completed, assuming we would single engine taxi, the crossbleed should be set in the OPEN position to run both packs. In my company, we keep the crossbleed in the AUTO position. I believe that by feeding both packs we save fuel but I have no reference or data to show that. Does anyone know? Thank you in advance.
