This is to anyone operating ME aircraft (assuming multi fuel tank installation with crossfeed).
Could you check your Crew Drills for fuel leaks and subsequent engine shutdown/failure.
In particular, what information is offered to determine source of leak and what would be the effect of a leak UPSTREAM of the LP cock. From what I can find in our 744 QRH, it would be POSSIBLE (not necessarily probable) that following the drills, without thinking it through, COULD lead to considerable fuel loss.
I would appreciate any input from anyone else out there.
