Sustained Rate of Turn Calculator

The sustained rate of turn ($R$) is a measure of an aircraft’s ability to maintain a constant rate of turn, typically expressed in degrees per second. It’s an important parameter in aircraft design and aerodynamics because it relates to an aircraft’s maneuverability and its ability to perform turns efficiently.

The formula for calculating the sustained rate of turn ($R$) is as follows:

• $R$ is the sustained rate of turn (typically in degrees 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).
• $g$ is the acceleration due to gravity (approximately 9.81 m/s² or 32.2 ft/s²).
