Conditions under which the most favorable for take off attack angle is small were clarified. It has been alleged by another author that a drawback of this takeoff method was a rather long takeoff run, especially in the case of poor ground. Here, the opposite result was obtained: the more the resistance coefficient of ground (the poorer the ground), the larger are the optimum attack angle and the aircraft lift coefficient during takeoff. It was explained from the physical standpoint by the fact that aerodynamic wing relief not only makes it possible to realize the well known effect of reducing ground resistance forces, but also to reduce the coefficient of resistance to wheel movement.
