30° angle of bank When airspeed is held constant, a larger angle of bank will result in a smaller turn radius and a  greater turn rate. Constant Airspeed 20° angle of bank 10° angle of bank 40 knots When angle of bank is held constant, a lower airspeed will  result in a smaller turn radius and greater turn rate. Constant Angle of Bank 50 knots 60 knots Figure 6-12. Angle of airspeed and bank regulate rate and radius of turn. 6-11
