Embodiment Construction
[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.
[0057] figure 1 It shows the flow of an embodiment of the method for predicting the risk of tail strike of an aircraft based on stepwise regression in the present invention. See figure 1 , the implementation steps of the method of this embodiment are described in detail as follows.
[0058] Step 1: The system receives external QAR parameter input.
[0059] The input QAR parameters include: pitch angle, airspeed, ground speed, wind speed, engine speed, takeoff weight, center of gravity position, airport altitude, runway length, etc.
[0060] The above QAR (Quick Access Recorder) parameters are obtained through secondary calculation after de...
