Just like any other plane does. It's called the Bournoulli principle. In fluid dynamics, Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. So, the shape of the wing causes the air to travel over the wing faster than the air travelling under the wing. The faster air has a lower pressure than the slower air, so a pressure difference is created across the wing. The pressure difference causes lift on the wing. When the plane is moving fast enough so that lift force exceeds the weight of the plane, it lifts off the ground.

How does an airplane take off the ground?
he engine is accelerared and the airplane moves down the runway gaining sped. When speed is high enough, 'lift' is created around the wings and it lifts off the ground.
What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
How can air make an object lift off the ground?
Air cannot do that alone. Airplane wings are shaped such that a forward motion will force them to lift.
How does the 747 lift off the ground?
The engines provide thrust, making the plane move forward. As the plane picks up speed the air flows over the wing, creating lift. Once the lift reaches a certain amount, the plane lifts off the ground.
Why does a wing lift an airplane off the ground?
A wing lifts an airplane off the ground through the Bernoulli's principle, where the shape of the wing creates a pressure difference between the upper and lower surfaces. This pressure difference generates lift, which counteracts the force of gravity and allows the airplane to become airborne.
What do you feel on an airplane takeoff?
When an airplane takes off, passengers will feel the acceleration and lift off of the plane as it leaves the ground. Sometimes this can make passengers nervous, or as it receives elevation, it can make peoples ears pop.
How many minutes does it take a Boeing 747 to lift off?
About one minute from brake release to lift off at maximum take off weight.
What happens when an airplane takes off against the wind?
It then produces lift due to wing configuration and can take off
An airplane would not be able to fly if it did not have a propeller. Why not?
It needs an engine to move it forward so that the wings generate lift. While stationary the wings generate no lift, or at least not enough to lift the plane off of the ground.
What type of energy does an airplane taking off have?
An airplane taking off has kinetic energy, which is the energy an object possesses due to its motion. As the airplane accelerates down the runway and gains speed, it builds up kinetic energy that is then used to lift off the ground and continue its flight.
How much fuel is required to get a 747 off the ground?
1 milerlitre
