The rotation of a spacecraft about its vertical axis so as to cause the spacecraft's longitudinal axis to deviate left or right from the direction of flight. The yaw axis is referred to as the z axis. Menu
A situation where a bullet “wobbles” on its axis at a small angle to the line of flight. In yaw, a bullet's tip is normally on the axis of the path but the base is spiraling around that axis. The spin of the bullet causes it to settle into stable flight with both tip and base on the same path axis, usually within 40 to 100 yards for a rifle.
The act of sheering suddenly and uncertainly from a vessel's course. It may be caused by poor steering, by the condition of the sea, or by the characteristics of the vessel's underbody or by any combination of the foregoing.
An undesirable characteristic in airplanes. A plane that yaws is one in which the tail or nose (or both) will make undesirable side-to-side movements away from the desired flight path. See also pitch and roll.
a sidewise movement of a vehicle in turning; movement of a vehicle in another direction than that in which it is headed; sidewise motion produced when centrifugal force exceeds traction force. Often the result of overreaction or exceeding the critical speed. Sometimes revealed by tiremarks on the roadway.
