For an airplane taking off I believe that would be a combination of Bernoulli's principle and ground effect.
This is to allow the airplane to rotate when it is taking off. (Rotating is when the pilot pulls back, raises the nose of the aircraft, and the aircraft rises into the air). If the aircraft did not have this raised tail-end, a "tail-strike" would happen, which damages the aircraft.
