Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
An airfoil that has the same shape on both sides of its center line. A symmetrical airfoil has a very small change in the location of its center of pressure as its angle of attack changes. For this reason, symmetrical airfoils are often used for helicopter rotors.
Industry:Aviation
An air-fuel mixture that contains less than 15 parts of air to 1 part of fuel, by weight.
Industry:Aviation
An airline that carries passengers or cargo for hire, but does not operate according to a regular or published schedule.
Industry:Aviation
An air-oil heat exchanger, used to remove excess heat from the lubricating oil. If the oil is too hot as it leaves the engine, it flows through the oil cooler, where it gives up the excess heat to the air flowing through or around the tubes in the cooler. The cooled oil then returns to the engine oil sump or to the oil tank.
Industry:Aviation
An airplane certificated under 14 CFR Part 23 for flight without restrictions other than those shown to be necessary as the result of a required flight test. An acrobatic category airplane is stressed for a limit maneuvering load factor of +6.0, and –3.0.
Industry:Aviation
An airplane control surface used to increase the camber, or curvature, of the wing airfoil. This increases both the lift and the drag produced by the wing.
By increasing the lift, the airplane can be landed at a slower airspeed, and by increasing the drag, the airplane can descend at a steeper angle without building up excessive airspeed. Some landing flaps increase the area of the wing as well as the camber.
Industry:Aviation
An airplane having only one main supporting wing. Up through the 1920s, most airplanes were biplanes (airplanes having two wings) because of the ease of bracing. But as engineering knowledge increased, engineers were able to make monoplanes of sufficient strength. The lower drag of a monoplane makes it more efficient than a biplane.
Industry:Aviation
An airplane having two main supporting aerodynamic surfaces (wings). The wings of a biplane are normally mounted so that one is approximately above the other.
Industry:Aviation
An airplane landing in which enough forces have been transmitted into the structure to have likely caused damage.
Industry:Aviation
An airplane or glider whose wing is rigidly attached to the structure. The term fixed-wing is used to distinguish these aircraft from rotary-wing aircraft, such as helicopters and autogiros.
