The invention discloses a tilt guidance method for a lift type aircraft flying in a thin flow region. The method includes the steps that a lateral unit vector is determined according to geocenter radius vectors of a launching point and a lateral guidance target point of the aircraft; the lateral position and the lateral speed of the aircraft in the direction of the lateral unit vector are calculated according to the lateral unit vector and the real-time position and the real-time speed of the aircraft under a launch coordinate system; lateral guidance force and an overload instruction are calculated through proportional and differential feedback according to the lateral position and the lateral speed; a tilt angle instruction is calculated according to the lateral guidance force. By means of the method, tilt guidance of the lift type aircraft flying in the thin flow region can be conveniently achieved, and the purpose of lateral guidance of the lift type aircraft flying in the thin flow region is achieved. 本发
