The negative pitch rate (q) is a measure of the rate at which an aircraft rotates about its longitudinal axis (roll axis) in the negative or nose-down pitch direction. This parameter is crucial for understanding and controlling the aircraft’s pitch motion during various phases of flight.
The formula for the negative pitch rate (q) can be defined as follows:
- Negative 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-down angle) during the time interval.
- Δt is the time interval over which the change in pitch angle occurs, measured in seconds (s
