A330 fuel imbalance
Was recently having a conversation with a TRE on the A330/340 and he came out with a statement… if you lose an engine on the A330, you should open the cross-feed and leave it open (assuming you have established that you do not have a leak).
He was totally against following the ECAM and monitoring the fuel and when a fuel imbalance started to develop, then follow the fuel imbalance procedure which calls for the cross-feed to be opened and the pumps on the low side to be turned off (low side would be the side with the good engine) his point being that, you have a good engine with pumps on the other wing sending fuel to it! I personally like to stick to airbus procedures, but was interested in getting some other opinions……..
