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 ...
A flexible, thermosetting resin used as a chemical-resistant coating. Epoxy resins can be reinforced with fiberglass or filaments of boron or carbon to make high-strength structural materials.
Industry:Aviation
A flexible, vertical antenna often used with high-frequency (HF) and very-high-frequency (VHF) radio equipment. The length of a whip antenna is one-quarter the wavelength of the frequency to which the antenna is resonant. A whip antenna is nondirectional; it transmits or receives its signals equally well in all directions.
Industry:Aviation
A flight condition at the beginning of a turn in which the nose of an airplane starts to move in the direction opposite the direction the turn is being made.
Adverse yaw is caused by the induced drag produced by the downward-deflected aileron holding back the wing as it begins to rise.
“Advise intentions” (air traffic control). A request meaning “Tell me what you plan to do.”
Industry:Aviation
A flight condition in which a pilot flies an aircraft according to visual flight rules (VFR) above a solid layer of clouds. While flying in the clear above the clouds, the pilot can operate under visual flight rules, but in order to reach VFR-On-Top conditions, the aircraft must pass through the clouds. When flying through the clouds, the aircraft must be operated according to instrument flight rules (IFR).
Industry:Aviation
A flight condition in which the aerodynamic forces acting on the control surfaces are balanced, and the aircraft is able to fly straight and level with no control input.
Industry:Aviation
A flight condition of an aircraft in which the aircraft rotates about its vertical axis. Yawing is not the same as turning, because an aircraft can be yawed and continue in straight flight with the wind striking it from the side. When an airplane is turned, it follows a curved flight path, with the wind always flowing parallel to its longitudinal axis.
Industry:Aviation
A flight condition that can occur when operating a swept wing airplane in the transonic speed range. Under certain conditions a shock wave forms in the root portion of the wing and causes the air behind it to separate. This shock-induced separation causes the center of lift to move aft. At the same time, the disturbed air causes the horizontal stabilizer to lose some of its effectiveness. The airplane develops a nose-down pitch, or tucks under.
Industry:Aviation
A flight for the purpose of returning an aircraft to base, delivering an aircraft from one location to another, or moving an aircraft to and from a maintenance base.
Ferry flights, under certain conditions, may be conducted under terms of a special flight permit.
Industry:Aviation
A flight instrument that indicates the flight Mach number of an aircraft. The mechanism inside a Machmeter includes a bellows that measures the difference between pitot pressure and static pressure. It also contains an aneroid that modifies the output of the differential pressure bellows to correct for the changes in altitude.
Industry:Aviation
A flight instrument that provides the pilot with a visual reference when the natural horizon is not visible. A bar or display, held in a constant relationship with the earth’s horizon by a gyro, serves as the reference.
