Airplanes come in all shapes and sizes but for most of us, the typical aircraft is a commercial jetliner crossing the skies. Not seen are the weird aircraft - the experimental, the special purpose, or the whimsical. Enjoy. A fixed wing aircraft is an aircraft capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft in which the wings form a rotor mounted on a spinning shaft and ornithopters in which the wings flap in similar manner to a bird. The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang-gliders and aeroplanes using wing-warping or variable geometry are all regarded as fixed-wing aircraft. A powered fixed-wing aircraft that gains forward thrust from an engine is typically called an aeroplane, airplane, or simply a plane. Aeroplanes include powered paragliders, powered hang gliders and some ground effect vehicles. Unpowered fixed-wing aircraft, including free-flying gliders of various kinds and tethered kites, can use moving air to gain height. Most fixed-wing aircraft are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.
