Whenever I start a flight with the 747-400, I get a low fuel warning. This warning occurs all through-out my flight. The message says that I can press control+X to be automatically refueled, but the short-cut seems to not work , because the message will return in five to eight minutes. Anyone, any thoughts on what's causing this?

Go to AIRCRAFT and down to REALISM SETTINGS then in the window which pops up, untick the "FLYING TIPS".I think this should work.RegardsKjetil
