Instantaneous Turn Rate Calculator

The instantaneous turn rate ($q$) is a measure of how quickly an aircraft can change its heading or direction by executing a coordinated turn. It represents the angular rate of rotation (in degrees per second or radians per second) around the aircraft’s vertical axis during the turn. This parameter is crucial for assessing an aircraft’s agility and maneuverability.

The formula for calculating the instantaneous turn rate ($q$) is as follows:

• $q$ is the instantaneous turn rate (typically in degrees per second or radians per second).
• $V$ is the true airspeed (in meters per second or feet per second).
• $\varphi$ is the bank angle of the aircraft (in radians).
• $R$ is the turn radius (in meters or feet).
