Plane :

Plane (from French plane, and this will increase from the Latin avis, bird), also called airplane, Aerodyne is a fixed-wing or aircraft heavier than air, fitted with wings and a body capable of flying cargo, propelled always by one or more engines. The planes include the monoplane, biplanes and triplane. As defined by ICAO is an engine propelled by Aerodyne, which must lift its in-flight reactions mainly exerted on aerodynamic surfaces that remain fixed in certain flight conditions. In the case of not having engine would be a glider and in the case of exceeding the speed of sound are called supersonic aircraft. They fall for use as civilian aircraft (which can be cargo, passenger transport, training, health, fire, etc.). And military aircraft (loading, transport of troops, fighters, bombers, reconnaissance or spies, resupply in flight, etc.).. They can also be classified according to their power plant; aircraft powered by piston engines, jet engines (turbojet, Turbofan and turboprop) or thrusters (rockets). Its working principle se basa en la aerodynamic force acting on the wings, making it produces a lift. This originates from the difference in pressure between the upper and lower wing, produced by its special form.
