737 centre tank pump u/s
Guys, heres one for ya. If you have a centre tank pump u/s, the boeing dispatch guide states that you leave the crossfeed open and the remaining pump on. Is this a wise configuration for t/o or is it better to use the wing tanks for t/o and then in the climb out turn on the cross feed and remianing centre tank pump and begin using the centre tank. I am all ears on this one.
