After adopting the correcting method of flight path Angle, flight path planned is further modified and ideal reference flight path is obtained.

To yaw back and forth about a flight path as if seeking a new direction or another Angle of attack. used of an aircraft a rocket or a space vehicle.

The effects of the cocktail on overload, the level and vertical acceleration on flight path Angle, sinking velocity and extra required propulsion were analyzed during the glide of the aircraft.
