出现真的燃油不平衡的原因
物理高中所有公式飞⾏中由于燃油供给和燃油回油系统问题，导致燃油不平衡。FUEL IMBALANCE 信息。
出现燃油不平衡的原因有以下⽅⾯, 如果能将燃油系统管路图联系到以下各点看出油是怎么串到其他油箱的，这或许只是如⼩孩⼦⾛迷宫游戏⼀样。
但你获得的不仅仅是⼀个⾛通了管道，重要的，这是看机械管路图起步的重要⼀课。
1. Scavenge system outlet float valve is stuck open or damaged,
resulting in premature center wing tank (CWT) to main tank
transfer on one side. Transfer will occur once the scavenge inlet
valve opens (e attached table).
2. Scavenge system jet pump check valve is stuck open, resulting in
transfer from the one main tank to the center tank. Condition will
occur when the scavenge inlet float valves are open and outlet float
valves are still clod (e attached table).

scavenging from the center tank into the associated wing tank.
Imbalance will occur when both the scavenge inlet and outlet float
valves are open (e attached table).
4. A main boost pump discharge check valve leak, resulting in transfer

fuel pressure to the engines from the center tank.
5. Suction feed bypass check valve leak, resulting in transfer to the
main tanks when the override/jettison pumps are supplying fuel
pressure to the engines from the center tank. Condition will occur
throughout entire flight.
6. Fuel feed manifold leak, resulting in transfer to a main tank when
the override/jettison pumps are supplying fuel pressure to the

7. Loo or parated center tank scavenge jet pump outlet line at bnut
connection, resulting in transfer to the center tank on the
ground or in flight, with the main boost pumps on or off.
8. Refuel manifold leak, resulting in transfer from one main tank to
another main tank. Noticeable on the ground during main tank
pressure defueling. Can also result in the overfilling of a main tank
in to its expansion space during refueling, then during flight that

main tank would remain at the fuel quantity indication system’s
“full” level, while the opposite main tank is drawn down below
“full” after the center pumps are shut off.
9. Center fuel pump pressure below the main fuel boost pump’s
pressure of 12 psi, but above the low-pressure switch t point of 8
psi. Can result in premature fuel burn from a main tank due to that
tank’s boost pumps overriding the affected center pump.
