Put simply, when a plane is propelled forward by it's engines, the air has to flow over its wings, either above the wing or below it. The wing is shaped so that air travelling over the top of it has to travel slightly further, and therefore more quickly than the air flowing beneath the wing. As the faster air moves, the lower the pressure it exerts, it follows that air underneath the wing will be exerting a relatively higher pressure upon the wing's underside and it is this that causes the airplane to lift and fly.
Hope that all makes sense.
First we need some kind of engine to make the plane go forward through the air. Most of today’s large planes use jet engines. A jet engine takes in air through a big wide mouth, compresses the air, and uses it to burn a jet fuel that is something like gasoline. The burning fuel gives a blast of hot gases, a jet, out of the back of the engine. The blast of gases backward pushes the plane forward.
Secondly, we need a wing to give lift and hold up the moving plane. The wing has an upward slant facing forward. Part of the lift comes from moving air pushing against the underside of the wing. Much more of the lift comes from the wing’s shape. It is rounded in front so that air moving over the top side of the wing must move farther and therefore faster than over the bottom. Since faster moving air has a lower pressure, this means that the pressure against the top side of the wing is lower than the pressure against the bottom. That’s where most of the lift comes from.
In order to fly a plane needs movement from propulsion by an engine and lift from a wing.
Some planes fly by a wire.the powered airplane were invented by the Wright Brothers.Glider plane don't need engine to fly it uses air current.some planes do many jobs for people.some fire plane help forest if its on fire.The space Shuttle is the worlds fastest and heaviest Glider.
A plane will fly when the pressure beneath the wings is greater that the wight of the actual plane, and what creates that pressure? The speed of the plane. And what speeds the plane? The engines. Just like when you walk up a stairwell your foot pushes down on the stairs making you go up. So too, the engine forces air from the back making the plane move forward causing pressure to build under the wings, and once that pressure (under the wings) is greater than the wight of the plane lift off is achieved!
It works by creating lift using it wings and propeller.
Aeroplane fly by air rush under the wind so that make the lift
Air going over top of the wing has to travel faster then air going under the wing which creates a low pressure under the wing generating lift.
