Airplanes & equipment

artificial horizon

Aviation; Airplanes & equipment

A vacuum-powered panel instrument that displays pitch and roll movements about the lateral and longitudinal axes.

aspect ratio

Aviation; Airplanes & equipment

The ratio of the span to the chord of an airfoil—a high-aspect ratio wing has wide span and narrow chord, and vice-versa for a low-aspect ratio wing.

An aircraft, often wingless, with unpowered rotary airfoil blades that auto-rotate and serve as wings as they move through the air when mounted on a powered aircraft (or, in some cases, a glider). ...

auto-rotation

Aviation; Airplanes & equipment

Automatic rotation of rotary blades from a helicopter in an unpowered glide or the forward movement of an autogyro.

automatic terminal information service (ATIS)

Aviation; Airplanes & equipment

Continuous broadcast of recorded non-control information in selected terminal areas, to improve controller effectiveness and to relieve frequency congestion by automating repetitive transmissions of ...

balanced control surface

Aviation; Airplanes & equipment

A movable control surface, as an aileron or rudder, having an added physical extension or weights forward of the hinge-point to reduce forces on a joystick or yoke. See ELEPHANT EARS (2).

bernoulli effect or law or theorem

Aviation; Airplanes & equipment

Since the pressure of a fluid is proportional to its velocity, airflow over the upper surface of an airfoil causes suction (lift) because the airstream has been speeded up in relation to positive ...
