What's the mission? Are you fueling an ultralite?


In flight transfer of fuel from aux tank to main header tank in a
Bowers Fly Baby.


That suggests a minimum transfer rate of a pint a minute would be needed
to keep up with the greatest conceivable flow - but a gallon a minute
would do nicely?

Header tank is 16 gal. After that has gone down to 10 the aux fuel
can be sent to it. That allows approximately 2 hours to transfer the
6 aux gallons to the main (allowing for half hour reserve). Not that
I want to do it that slowly. Actually, for optimal CG it would be
nice to send the aux up when the main is down to reserve so that would
require a much faster rate.
