I don't understand what you are trying to say in post #41.
But if I received ECAM "FUEL IMBALANCE" or "FUEL L (R) WING TK LO LVL"
Then I would:
"Applicable to: ALL
.........
IF NO FUEL LEAK AND FUEL IMBALANCE:
FUEL X FEED ON
TK PUMP 1 (on side with LO LVL) OFF
TK PUMP 2 (on side with LO LVL) OFF
Note:
TK PUMP 1+2 (on side with LO LVL) LO
PR warning will be triggered."
In order to use fuel from the tank with more fuel, then I would bank the aircraft by 3 degs towards the lower level tank.
Why do you think either engine would quit? The only warning is to avoid -ve g. In steady level flight all the fuel will experience 1g, but there will be a bigger pressure head from the higher fuel tank.
