How Does An Airplane Fly?

It comes down to the air foils (or "wings" to you). Air foils is a better term because all airplanes need at least two sets of foils for stability, the main big ones in the middle of the plain, and smaller ones usually by the tail. These are the surfaces that provide lift to the aircraft. Lift is a pushing up force. If the airplane goes along fast (being pushed forward by its engines), then air is flowing fast over the air foils. The trick to manned flight was learning what shape to make the air foils. They are designed so that air rushes over the top of them faster than it rushes underneath. The slightly slower air under the wing pushes in all directions... including upwards. The more this upward force, the more lift the airplane gets.

When a large passenger airplane comes to land the wings need to do various things to reduce the amount of lift in a slow and controlled manner. One of the main tricks is to move the ailorons (little flaps extending at the rear of the wing) so that the air is able to rush underneath the wing faster, thus reducing how much air pushes the wing up. The airlorons can tilt in various ways, even allowing air to escape through a small gap between them and the main part of the wing. Upon landing the ailorons tupically flip up to help slow the plane down on the runway.

The first paragraph was marginally correct, but the second was pure gibberish. First it's spelled "aileron", second, that is the job of the "flaps", not the ailerons. The flaps actually increase lift, while at the same time increasing drag. This allows the plane to fly slower than normal, for a low speed controlled landing, instead of falling out of the sky when the pilot tries to slow down too much. Upon landing, the "drag brakes" flip up, not the ailerons. I've been a pilot for over fifty years, and if I relied on the first answer to guide me, I wouldn't have made it one year.

Airplane
wings are shaped to make air move faster over the top of the wing. When
air moves faster, the pressure of the air decreases. So the pressure on
the top of the wing is less than the pressure on the bottom of the wing.
The difference in pressure creates a force on the wing that lifts the
wing up into the air.
