that's a tough one.    The current Andair valve will leak because it has =
small holes in the "OUT" direction.   ...but it will slow things down =
while you are taxiing.   I would be hesitant to have a check valve with =
no bypass holes because the failure mode is unacceptable (internal tank =
pressure).
The original (Don Goetz) winglets were very small and mainly there to =
solve this problem.   So far, I think that is the best idea going.
(add small winglets).  It's amazing what a couple inches will do reduce =
spillage.

Does anyone out there have a better idea?  Low cracking pressure check =
