To adjust the aerodynamic forces on the control surfaces so that the aircraft maintains the set attitude without any control input.
Industry:Aviation
A combination of rolling and yawing oscillations that normally occurs when the dihedral effects of an aircraft are more powerful than the directional stability. Usually dynamically stable but objectionable in an airplane because of the oscillatory nature.
Industry:Aviation
A system of lights similar to the VASI, but consisting of one row of lights in two- or four-light systems. A pilot on the correct glideslope will see two white lights and two red lights. See VASI.
Industry:Aviation
A configuration in which the span of the forward wings is substantially less than that of the main wing.
Industry:Aviation
A small auxiliary hinged portion of a movable control surface that can be adjusted during flight to a position resulting in a balance of control forces.
Industry:Aviation
A condition that exists when landing on a surface with standing water deeper than the tread depth of the tires. When the brakes are applied, there is a possibility that the brake will lock up and the tyre will ride on the surface of the water, much like a water ski. When the tyres are hydroplaning, directional control and braking action are virtually impossible. An effective anti-skid system can minimise the effects of hydroplaning.
Industry:Aviation
A type of radar used at an airport to guide an aircraft through the final stages of landing, providing horizontal and vertical guidance. The radar operator directs the pilot to change heading or adjust the descent rate to keep the aircraft on a path that allows it to touch down at the correct spot on the runway.
Industry:Aviation
An altitude depicted on an instrument approach chart with overscored altitude value at which or below aircraft are required to maintain altitude.
Industry:Aviation
The boundary layer between the troposphere and the mesosphere which acts as a lid to confine most of the water vapor, and the associated weather, to the troposphere.
