Level turn rate (ω) = (g √n^2-1)/V
g – Acceleration due to gravity in m/s^2
n – Load factor
V – Free stream velocity of air (V) in m/s
Level turn rate (ω) is the number of degrees of heading change per unit time(measured in per second) also, it is the one in which curved flight path is in parallel to the plane of the ground; that is in a level turn rate the altitude remains constant.
