Airplanes & equipment
Laminar-flow airfoil
Aviation; Airplanes & equipment
A low-drag airfoil designed to maintain laminar (smooth, continuous) flow over a high percentage of the CHORD about itself. Often relatively thin, especially along the leading edge, with most of its ...
Adiabatic lapse rate
Aviation; Airplanes & equipment
The rate at which ascending air cools and descending air warms, given that no heat is added or taken away. The rate for dry air (DALR) is based on 5.4° F per 1000' altitude (1° per 100 meters). Moist ...
Yaw
Aviation; Airplanes & equipment
Of the three axes in flight, this specifies the side-to-side movement of an aircraft on its vertical axis, as in skewing. Compare PITCH and ROLL.
Adverse yaw
Aviation; Airplanes & equipment
Yaw generated when the ailerons are used. The lifting wing generates more drag, causing an airplane to yaw (turn) toward it.
Accessory group
Aviation; Airplanes & equipment
Mechanical and electrical units mounted on an engine necessary for its operation, such as starter, magnetos, fuel pumps, etc.
Yoke
Aviation; Airplanes & equipment
The control wheel of an aircraft, akin to a automobile steering wheel.
