The negative roll rate (q) is a measure of the rate at which an aircraft rotates about its lateral axis (roll axis) in the negative or left-roll direction. It is an important parameter for understanding the aircraft’s roll motion during maneuvers and for maintaining control.
The formula for the negative roll rate (q) can be defined as follows:
- Negative Roll Rate (q) is the rate of rotation about the lateral axis, measured in radians per second (rad/s).
- ΔΦ represents the change in roll angle (bank angle) during the time interval.
- Δt is the time interval over which the change in roll angle occurs, measured in seconds (s).
