A fuel isolation valve isolates the carry-through tank from the fuselage
tank. The valve is commanded OPEN on-ground for refueling operations
and is CLOSED at all other times to isolate the fuselage tank pressure
head from the C/T tank. The valve is controlled automatically by aircraft
avionics. Valve remains open on the ground, until commanded closed
after first engine start.
