How much does a 747 carry in fuel?
How much does a 747 carry in fuel?
According to the Boeing website, the 747 burns approximately 12 litres per kilometre. 747 can carry as many as 568 people. It can carry up to 238,840 litres of fuel.
How much fuel does a wing hold?
The wings of an aircraft holds about 70% of its total fuel capacity. Each wing of an Airbus A380 can hold about 120000 kgs (264554 pounds). The fuel tanks at the tail section (trim tanks), holds about 18000 kgs of fuel.
Where does a 747 store fuel?
Fighter jets often have fuel stored behind the pilot’s seat, but big airliners like the B747 store massive amounts of fuel in their wings.
What kind of fuel tank does a 747 have?
William M. Cavage and others were studied on the inert gas distribution of center wing fuel tank in Boeing 747.
What kind of vent system does a 747 have?
Venting analysis of a Boeing 747 aircraft fuel tank has been carried out by Jensen (2000).
Where does the fuel come from for a three engine airplane?
Once these tanks are empty, fuel is used from the wing tanks. On three-engine airplanes, center tank fuel and any auxiliary tank fuel is used until the remaining fuel in the center tank equals the fuel quantity in the tanks on the left and right wings. At this point, fuel is used equally from the wing tanks and center tank.
When do you burn off fuel on a 747?
In particular, during a long trip, it is important that the fuel in some tanks be burned off before using the fuel in other tanks. Otherwise, the aircraft can become unbalanced.Fuel management in the 747-400 is largely automated, but there are still certain actions that are required from the crew.
Where does the fuel come from on a 747?
Any engine can draw fuel from any fuel tank, fuel can only be suction fed from the main wings tanks. Each main tank and stab tank has AC boost pump + inboard main tanks and center wing tank have override/jettison AC pump.
How much does a Boeing 747 fuel tank weigh?
This amount weighs in excess of 380,000 pounds. (Pilots normally discuss fuel in terms of weight rather than volume.) The distribution of fuel among these tanks has a profound effect on how the aircraft performs. In particular, during a long trip, it is important that the fuel in some tanks be burned off before using the fuel in other tanks.
Where is the scavenge pump on a 747?
Center tank has a scavenge pump that will automaticly transfer fuel to main tank 2 if center tank fuel pumps detect low pressure. A vented surge tank is located near the tip of each wing and provide positive pressure on fuel tanks during cruise.
Can a Boeing 747 fuel tank be crossfeed?
Technically yes but realistically no, Boeing doesn’t say yes as it probably won’t work as it would have to go via the crossfeed system. 3. Does stab tank really has boost pump, since the symbol for pump (on secondary EICAS under FUEL) is the same as for overide/jettison pumps and fuel is also fed from this tank in fuel jettison operation?
