Amadis -dual pump failure on an inner tank after only being in the cruise for a short time.The scenario continues with maintaining the level whilst waiting for the fuel to deareate and feeding both engines from the tank with the working pumps.Following deareation going back to gravity feeding on the affected side. This will lead to an imbalance and if you are unlucky you would be out of the fcom limit.
This is currently a discussion point at work. I am really interested how you would gravity cross feed
