As the airplane speeds up the air flowing around the control surfaces speeds up as well. When this happens the horizontal stabilizer is deflected into the wind causing the nose of the aircraft to rise. As the nose rises the angle of the wings also increases and create lift by 'air deflection' and 'bernoullis principle'. Many other factors are involved to create lift, these are just the main principles.
Obviously so it can overcome gravity and take off.
No one airplane, no one answer. Depends on the weight of the airplane and the size of the wings. Light planes designed for short take offs may lift off at 30 mph. A Boeing 737 jet might lift at 150 mph.
An airplane flap extends the wing area during take-off and landing, to give extra lift at low speed. This allows the airplane to take-off and land at reasonably low speeds (around 150mph for most jet airliners).
It then produces lift due to wing configuration and can take off
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.
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.
Moving forward, air rushing over the wings causes them to produce lift. When the amount of lift created is greater than the weight of the plane it will rise off the ground.
The total of the plane, cargo and fuel.
No. They need air for lift.
Yes you can take it on an airplane but you have to keep it switched off.You can use your phone only during take off and during landing. During the flight itself, you are not allowed to use your cell phone.Yes, but they usually ask you to turn them off during at least take off and landing (possibly the rest of the flight, I can't remember).
Airplane is a mechanical structure that has the ability to overcome the gravity and lift off, with the assist of an engine
No. On MOST airplanes, ailerons are separate from flaps. Ailerons are used to help steer the airplane, while flaps are lowered to change the aerodynamic shape of the wing to provide more lift during take off and landing.
