Calculating the approximate
turn radius of an air vehicle

Approximate Turn Radius formula for an Air Vehicle (plane/missile/etc)

R = V2 / A

Where:

R: Turning Radius of air vehicle in meters.
V: Velocity of air vehicle in meters per second
A : Turning acceleration capability of air vehicle in meters/sec2.

EXAMPLE

A supersonic anti-ship missile traveling at Mach 1.5 at sea level (510 m/sec) and with a turn capability of 10 gees (98 m/sec2). What is it's turn radius?

5102 / 98 = 2,654~ meters.
