In aircraft design and aerodynamics, the positive pitch rate (q) is a measure of the rate at which an aircraft rotates about its longitudinal axis (roll axis) in the positive or nose-up pitch direction. This parameter is essential for controlling the aircraft’s pitch motion during various phases of flight.
The formula for the positive pitch rate (q) can be defined as follows:
- Positive Pitch Rate (q) is the rate of rotation about the longitudinal axis, measured in radians per second (rad/s).
- Δθ represents the change in pitch angle (nose-up angle) during the time interval.
- Δt is the time interval over which the change in pitch angle occurs, measured in seconds (s).
