I understand that the fuel unbalance is used to correct an unbalance in weight. In other words shift the CG back to be were it belongs so you do not run out of aileron control.
Surely if an engine (I am sure the equivalent of several tons) drops from the wing you will notice it in the flight controls, engine indications have either disappeared or read zero, etc….
In order to rebalance the overall weight (engines and fuel) you may not want to fall in the trap of the Fuel Unbalance EICAS message and blindly INCREASE the unbalance even more?
What does common sense tell you in this case ?
To be honest, I have made up my mind on this one many years ago, I am just checking by opening this tread if I have not overlooked something.
