73X Fuel crossover valve question?

Recommended Posts

Guest Segwin

During normal flight should the crossover valve be open or closed?

As an added bonus question, why is it closed for take-off?A: If you spring a leak (noted by a "significant" fuel imbalance), all your fuel won't cross over to the leaking tank, leaving you with TWO fuel starved engines.Consequently, if you do get a fuel imbalance, your best bet is to examine WHY you have an imbalance before you hit the crossfeed switch.
