A320 refuel panel switch left in refuel position
Are there any fuel system problems likely to occur in flight or on ground after aircraft lands, if "Refuel/off/Defuel" switch left in "Refuel" position after refuel operation is over?
Refuel buses 501PP and 502 PP are not powered in flight,so fuel system operation may not be affected, but procedure insists on returning the switch to "off" position after refuel operation and it is a normal practice always.
