Astronautics

Rotation of a craft about its vertical body axis

In astronautics yaw is one of the three attitude angles of a spacecraft, rotation about the body's vertical (or yaw) axis, alongside pitch and roll, that together fix how the vehicle is pointed. Wertz's Spacecraft attitude determination and control treats yaw within the full attitude problem of sensing and commanding a craft's orientation. It is the same rotational degree of freedom that names a turn of an aircraft's nose or a ship's bow, realised here about a spacecraft's body axis and measured by the yaw angle and its rate.[1]

Unit
The rotation angle about the vertical body axis, and its rate
Recovery means
Not applicable
Measured by
Determined from attitude sensors as the yaw angle and yaw rate about the vehicle's vertical body axis

Flight dynamics

Side-to-side rotation of an aircraft's nose

In flight dynamics yaw is rotation of an aircraft about its vertical axis (the nose swinging left or right), controlled mainly by the rudder and coupled with roll in turns; directional (weathercock) stability is what returns the nose into the relative wind. Etkin and Reid's Dynamics of flight: Stability and control develops yaw as part of the aircraft's lateral-directional motion. It is the identical rotational degree of freedom seen in a spacecraft or a ship, here about an aircraft's vertical axis, measured by yaw angle, sideslip, and yaw rate.[2]

Unit
The rotation about the vertical axis, with yaw rate and sideslip angle
Recovery means
Not applicable
Measured by
Measured by yaw (heading) angle, yaw rate, and sideslip, with directional stability restoring the nose to the relative wind

Naval architecture

Rotation of a vessel about its vertical axis

In naval architecture yaw is rotation of a vessel about its vertical axis (the bow swinging off the intended heading), one of the six degrees of freedom of ship motion and the one a helmsman or autopilot corrects to hold course in waves and wind. Tupper's Introduction to naval architecture treats yaw among the vessel's motions and its coupling with sway and roll. It is the same rotational degree of freedom as an aircraft's or spacecraft's yaw, realised about a ship's vertical axis and measured by heading deviation and yaw rate.[3]

Unit
The rotation about the vertical axis, as heading deviation and yaw rate
Recovery means
Not applicable
Measured by
Measured as deviation from the intended heading and the yaw rate, corrected by rudder to hold course
