Hi Evryone,
I've been itching to ask this for a while.

http://www.planepictures.net/netshow.php?id=443145 after shutdown they have all six fuel pumps on but also they have the electric hydraulic pumps on and the engine driven ones off. My understanding is that there is 1 fuel pump to kept on for APU operation and the electric hydraulic pumps should be off and the engine ones on.

Can anybody explain if this is normal??
Thanks
