The positive yaw rate (r) is a measure of the rate at which an aircraft rotates about its vertical axis in the positive or clockwise direction when viewed from above. It is crucial for understanding and controlling the aircraft’s yawing motion or turning about the vertical axis.
The formula for the positive yaw rate (r) can be defined as follows:
- Positive Yaw Rate (r) is the rate of rotation about the vertical axis, measured in radians per second (rad/s)
- Δψ represents the change in yaw angle during the time interval.
- Δt is the time interval over which the change in yaw angle occurs, measured in seconds (s).
