Fuel Reserves
What is considered a remote or island destination?
Any airport at a geographic location offering no suitable alternate (civil or military) within 2 hours flying time.
For draining the reserves No. 1 and 4 main tanks must be below _____ pounds each
10,000
Use _______ lbs of fuel for scattered/numerous thunderstorms?
2,500lbs
Primary and secondary balancing techniques?
The primary technique is to feed fuel from the forward, center wing, or aft body tank to the low main tank(s). A secondary technique for fuel balancing is to gravity drain fuel to the aft body tank from the desired (heavy) main fuel tank(s).
When must all tank to engine manifold valves be open for takeoff, approach and landing?
10,500
For remote or island destinations, holding in lieu of an alternate airport is authorized. In such situations, plan for?
