This page shows the parts of an airplane and their functions. Airplanes are transportation devices which are designed tomove people and cargo from one place to another. Airplanes come inmany different shapes and sizes depending on the mission of the aircraft. The airplane shown on this slide is a turbine-powered airliner which has been chosen as a representative aircraft.
For any airplane tofly, you must lift the weight of the airplane itself, the fuel, the passengers, and the cargo. The wingsgenerate most of the lift to hold the plane in the air. To generate lift, the airplane must bepushed through the air. The jet engines, which are located beneath the wings, provide the thrust to push the airplane forward through the air. The air resists the motion in the form of aerodynamic drag.Some airplanes use propellers for the propulsion system instead of jets.
To control and maneuver the aircraft, smaller wings are located at the tail of the plane. The tail usually has a fixedhorizontal piece (called the horizontal stabilizer) and a fixed vertical piece (called the vertical stabilizer). The stabilizers' job is to provide stability for the aircraft, to keep it flying straight.The vertical stabilizer keeps the nose of the plane from swinging from side to side, while the horizontal stabilizer prevents an up-and-down motion of the nose. (On the Wright brother's first aircraft, thehorizontal stabilizer was placed in front of the wings. Such a configuration is called a canard after the French word for "duck").
An aircraft is a vehicle which is able to fly by being supported bythe air, or in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downwardthrust from jet engines.[1]

Although rockets and missiles also travel through the atmosphere, most are not considered aircraft because they use rocket thrust instead of aerodynamics as the...
