    I am not familiar with the term “max rate turns”. At a given speed, the minimum level turn radius is achieved by using the highest bank angle that won’t result in a stall. But the turn radius is V squared times a constant and then divided by the tangent of the bank angle. So slowing down and using a shallower angle can be much more effective in reducing the radius of the turn. For example, at 120 Kts, the turn radius using 45 degrees of bank is 1275 feet and the total space required to get turned around is 2550 feet. Slowing to 80 Kts and using a 30 degree bank has a turn radius of 982 feet and the total distance required is 1964 feet, a 23 percent reduction.
