How do plane land?

Answer 1

Without adequate thrust to provide forward motion and lift, an airplane will descend. Thus, the method of the descent is simply to slow down the engine. With the engine idling, the plane's only alternative is continued descent to the earth. Once near the earth, the pilot lowers the landing gear. Then he/she flairs the plane, bringing up its nose, raising the coefficient of lift and enabling the plane to continue its descent at a slower rate. With the help of ground effect (the air forced between the bottom of the wing and the surface of the earth) the descent is further slowed until the main landing gears contact the landing surface... optimally, a runway; or if a water landing, an unobstructed stretch of water of adequate depth.
