How many fuel tanks does a 747 have?
The 747-400 has eight fuel tanks, with a combined capacity of 57,164 gallons of Jet-A fuel.
Do planes have fuel gauges?
Airplanes have fuel quantity gauges. Though small aircraft have very inaccurate gauges large airliners have extremely accurate ones. Not only do we have an indication of fuel, but we also have fuel flow gauges (FF) which are calibrated to show fuel flow per hour. These indications are essential for fuel management.
How much does it cost to operate a 747 per hour?
More engines lead to higher prices. The average airborne operating cost of a Boeing 747-400 is between $24,000 and $27,000 per hour, around $39.08 to $43.97 per mile, using approximately $15,374 in fuel per hour.
What turbine engine component will prevent icing in the fuel during normal operations?
The engine anti-ice system, as installed on most types, serves solely to prevent ice build up on the air intake opening of the engine nacelle.
Why are wing tanks the last to be used in airplanes?
As the generated lift bends the wings upward, the weight of the fuel will counter that. As the plane loses weight in-flight due to burning fuel, so does the need for wing bending relief (less weight → less lift), that’s why the wing tanks are the last to be used.
Why is fuel put into the main wing tanks first?
Probably the main reason why fuel is put into the main wing tanks first is because on some airliners (if not most) the engines are fed directly from the wing tanks. Some airliners have to pump the fuel from center tanks into the wing tanks before the engines can utilize the fuel.
What happens if you fuel the belly of a plane first?
You would end up with the full fuel load in the center tank. When the flight crew arrives to take the plane they will have to transfer fuel into the wing tanks before take-off. If you are topping off the aircraft, it won’t matter if you fuel the belly or wings first.
Why is fuel consumed from the center of the tank?
Fuel is then consumed from the center tanks first to keep the most weight on the wings through the flight. The weight from the fuel will counter the upward bending of the wings, as nothing but the wings alone must bear the load of the cabin, and all of its passengers/cargo.
