Center tank fuel pump lights

Well, then for example you did take off with the center tank feeding the engines, how would fuel get to the engine driven fuel pumps if there was a loss of AC power? All the wing and center tank fuel pumps are AC power driven (except for the APU fuel pump in most cases), so in case of a failure, suction and gravity would feed the engines from the wing tanks. This would be highly unlikely in the event the fuel is coming from the center tank.

Hi All,Well I take off a few times a week with feed from the CTR tank (Boeing) and still here to tell the tale.When you feed from the CTR tank doesn't mean the wing tank is exluded from the feeding lines. Even when the CTR tank is empty or restricted flow will be taken over from the wing under pressure feed or suction feed.CheerioSjaako

I guess its different depeding on the carrier. I worked for two major carriers (both Airbus and Boeing operators) and takeoff with CTR tank fuel was prohibited.
