A320: Switching the Fuel pumps ON while refuelling
Hi,
During our training (long time ago) we were told by our instuctor not to switch the fuel pumps ON while refuelling, and we should wait untill refuelling is completed and then we can switch them ON.
recently, some pilots switchs the pumps to ON even though the refuelling is going on, and they are saying there is nothing mentioned in the FCOM on this matter.
my question is, is it allowed or not to switch them ON or wait untill refuelling is completed ?
Thanks in advance
