An aircraft is returned to service when it completes a test flight by an appropriately certified pilot. A certificated mechanic or authorized inspector must approve an aircraft for return to service after it has been inspected, repaired, or altered.
Industry:Aviation
An aircraft is underpowered when there is not enough power delivered to its propeller or rotor to give it the required performance.
Industry:Aviation
An aircraft maneuver in which the aircraft is autorotating (being pulled around by aerodynamic forces) as it descends, with one wing flying, and the other actually stalled. In a normal spin, the aircraft is pitched steeply nose down, but since it is descending, it has a very high angle of attack. Recovery is made by moving the control wheel forward (the elevators down). This decreases the angle of attack and allows the stalled wing to begin flying again, and the airplane stops spinning.
In a flat spin, the angle of attack cannot be lowered enough, even with full-down elevators to bring the wing out of its stalled condition. Flat spins are caused by the center of gravity of the aircraft being too far aft, allowing centrifugal force to flatten the spin. Very few aircraft can recover from an unintentional flat spin.
Industry:Aviation
An aircraft nose wheel tire that has a special deflector, or chine, molded into its sidewall. Chine tires are mounted on the nose wheel of jet aircraft whose engines are mounted on the rear of the fuselage.
When the aircraft lands on a wet or icy runway, the chine throws water and slush out to the side so that none of it gets into the engines.
Industry:Aviation
An aircraft part whose service life is limited to a specified number of operating hours or operating cycles.
Industry:Aviation
An aircraft pilot authorized by the Federal Aviation Administration to carry passengers or cargo for compensation or hire under certain conditions.
Industry:Aviation
An aircraft propeller which has provisions for adjusting the pitch of the blades on the ground when the engine is not running.
Industry:Aviation
An aircraft propeller whose blades can be moved to a pitch angle that produces reverse thrust. Reversible-pitch propellers are used to decrease the length of the landing roll needed by the airplane.
Industry:Aviation
An aircraft reciprocating engine equipped with a supercharger that allows it to maintain its rated sea-level horsepower to a specified higher altitude.
Industry:Aviation
An aircraft reciprocating engine with a built-in supercharger that boosts the sea-level rated horsepower of the engine.
