i heard that fuel tank of airplane is on the wing, is it true?

Question

if there are too much gas , It can't be landed. so captain needs to fly until gas is almost empty so they can landed.

Answer 1

Fuel tanks can either be in the wings, in the tail or in the center of the fuselage (body). Small aircraft tend to have them only in the wings and maybe on extra tanks at the tips of the wings. Large airliners generally have tanks in the wings and the center fuselage. Very large airliners can have tanks in all of those places, plus perhaps the tail.

The only time airliners dump fuel is in an emergency to get down to the maximum landing weight. If the aircraft lands above that weight, damage can be done to the aircraft. But,as I said, this is only done in emergencies. Flights are planned so that enough fuel is in the tanks to get there, plus legal reserves and maybe a bit extra in case the weather is ugly.

Small aircraft cannot dump fuel and only certain airliners can. If you can't dump fuel, you have to fly around until you burn it off. It depends on the emergency whether or not you can fly around and burn off fuel or risk a landing above the max landing weight.

Answer 2

not entirely correct wording of your question (I don't think) yes fuel tanks are frequently stored inside the wings. When you get an airplane like a 747 for example, since the fuselage is virtually taken up by passangers and thier luggage, they have to put the fuel where ever they can find room, which is the wings. Yes, occasionally when an airplane takes off and has an immediate problem requiring it to land right away they can Dump fuel to lighten the aircraft for landing. They also will sometimes stay in the immediate areea and "burn it down" while they truy to rectify the problem. Obviously if you have enough fuel on board for an eight hour flight and you need to land NOW, the quickest way to get rid of that excess weight is to dump it overboard.

Answer 3

Most planes DO have the (or some) fuel tank(s) in the wing, known as a "WET WING".
If too much fuel is in tank, making plane over safe landing weight, some planes have a "FUEL DUMP", to dump most (not all) of the fuel. Others have to fly around until enough burns off.
By the way, Drewpie. MD-80's/90's CAN dump fuel, the outlets are out under the wing tips. (I've built both until the end of the line for 20 years.)

Answer 4

Yes you are corect the fuel is in the wings., Think about this. the wings are at the balance point of the plane so having the fuel there is the best idea. If it is in the rear or front then when full the balance would be either behind or in front of the wings and could crash the plane. In the wings as the fuel is used it does not change the balance of the plane. They do have to be sure to use the same abount from each wing as they fly. Some planes will have fuel along the botom of the plane as well.

Answer 5

Almost every plane produced uses in-wing fuel tanks. Even the first trainer I flew (Piper Tomahawk) had "wet wings". It is a natural placement utilizing un-used space and makes weight/balance easier.

On many planes that have a maximum take-off weight routinely exceed their maximum landing weight fuel dump valves and pumps are installed for emergencies. These are not routinely used for environmental and safety reasons.

If you are talking about an emergency landing like the one in LA with the Airbus A320 you are correct they had to fly around until they had bled off a safe amount of fuel so they wouldn't be making an emergency landing with full tanks. This type of thing is a very extreme and rare event.

Answer 6

Yes the wings are fuel tanks. The only time a pilot has to land on `empty` is in an emergency. Then the pilot will make the decision to dump fuel.

Answer 7

Yes the fuel tanks are more then likely located in the wings, they are known as the mains, there is also usually fuel tanks located closer to the wing tips and are known as the tip tanks.

As far as in an emergency landing, dumping fuel is a last resort, if they can they usually like to get the aircraft to circle around and burn off the fuel.

Answer 8

definite the 747 could nicely be equipped at production facility or unfashionable-equipped with gasoline tanks in the H stab. not an spectacular theory as some years back, a Lufthansa 747 replaced into appearing touch and is going making use of a newly introduced 747 with H stab tanks. they crammed up the H stab thoroughly, yet purely had the wings offering gasoline...at last, the C of G became very unbalanced and brought about the 747 to result the runway tail-first. it replaced into pilot errors, yet its alot extra juggling in case you have gasoline weight in the H stab.

Answer 9

One other little point the others didn't mention is safety. In a crash landing the wings often depart the fuselage, taking all that fuel with them. Those in the cabin stand a better chance of survival.

Andrew nailed it!
