So is there no way of transferring fuel across? Or would there be issues with re-priming the lines after running it dry?
I’m sure it was written into their SOPs, just curious as to what the reasoning is to shutting down the engine?
There is no way to transfer fuel to another tank in flight (that I know of !), only option is to feed the engine from another tank.
Maybe they were concerned there was a fuel leak and followed that checklist which most probably called for the engine to be shutdown. Being close to TOD probably wouldn't be wise to start an investigation with the view to restarting the engine. Since it's a 4 engine aircraft safer to leave things be & sort it out on the ground.
