surface designed to develop a desired force by reaction with a fluid, especially air, that is flowing across the surface. For example, the fixed wing surfaces of an airplane produce lift, which opposes gravity.

Yaw

 

small angular deviations, relative to the vertical axis, from the course of, for example, an aircraft, a ship, or a motor vehicle; these deviations can occur alternately toward either side. For stability of motion to be preserved, these oscillations must be damped rapidly enough so that they do not interfere with control. If the oscillations damp slowly, damping devices are used.

yaw

[]
(mechanics)
The rotational or oscillatory movement of a ship, aircraft, rocket, or the like about a vertical axis. Also known as yawing.
The amount of this movement, that is, the angle of yaw.
To rotate or oscillate about a vertical axis.

yaw

yaw
Rotated coordinate system superimposed on photo print.
i. The rotation of an aircraft or a missile about its vertical axis so as to cause its longitudinal axis to deviate from the flight line or heading in its horizontal plane. Also known as yawing.
ii. To rotate or oscillate about a vertical axis.
iii. The rotation of a camera or a photograph coordinate system about either the photograph's z-axis or the exterior's z-axis.
