In Pull – up maneuver, Turn radius (R) = V^2/g(n-1)
V – free stream velocity of air in m/s
g – Acceleration due to gravity in m/s^2
n – Load factor ( Ratio of lift to weight force)
In Pull – up maneuver, Turn radius (R) is defined as the horizontal distance that an aircraft uses to turn, it varies as a function of bank angle and the square of airspeed.
