Answer: How many fuel tanks are there on the GlobalFlyer?
With 13 fuel tanks, getting the fuel to where it’s needed, while maintaining the balance and stability of the aircraft, requires constant supervision and monitoring. Each of the plane’s two booms has two tanks that also take up some of the space in the inner sections of the wings. Each outer wing section holds four fuel tanks. The last tank is situated behind Steve in the main fuselage, and this is the tank that feeds the engine. Valves are used to control the fuel flow from the outer sections of the wings to the boom tanks, from which it is then pumped into the tank below the engine.
