TURNING PERFORMANCE

This program will compute the turning radius of an aircraft based on its airspeed and bank angle.

Formula -
radius = speed2 / (gravity x tangent(bank angle))
time = 2 x PI x speed / (gravity x tangent(bank angle))
where: speed=feet per second (fps = knots x 1.69), kmph to fps conversion is done for you on form below
gravity =32.2 fps
