Aircraft

spin

Aviation; Aircraft

An aggravated stall that results in an airplane descending in a helical, or corkscrew path.

airfoil

Aviation; Aircraft

Any surface, such as a wing, propeller, rudder, or even a trim tab, which provides aerodynamic force when it interacts with a moving stream of air.

indicated airspeed (IAS)

Aviation; Aircraft

Shown on the dial of the instrument airspeed indicator on an aircraft. Indicated airspeed (IAS) is the airspeed indicator reading uncorrected for instrument, position, and other errors. Indicated ...

spiral instability

Aviation; Aircraft

A condition that exists when the static directional stability of the airplane is very strong as compared to the effect of its dihedral in maintaining lateral equilibrium.

airplane

Aviation; Aircraft

An engine-driven, fixed-wing aircraft heavier than air that is supported in flight by the dynamic reaction of air against its wings.

indicated altitude

Aviation; Aircraft

The altitude read directly from the altimeter (uncorrected) when it is set to the current altimeter setting.

The slipstream of a propeller-driven airplane rotates around the airplane. This slipstream strikes the left side of the vertical fin, causing the aircraft to yaw slightly. Rudder offset is sometimes ...
