A Deep learning Method for Landing Pitch Prediction based on Flight Data

With the development of the aviation industry, aircraft has increasingly become one of the most preferred longdistance transportation tools, and aviation safety incidents have attracted extensive attention. The key to dealing with aviation safety incidents is to accurately predict anomalies and potential hazards in advance and instruct pilots to perform corrective operations. As one of the safety incidents, tail strike may cause damage to the aircraft fuselage which may bring financial losses, or even threaten lives. However, there are few studies on tail strike in depth at present. In order to fill this gap, this paper mainly focuses on the tail strike risk, which is defined as the incident that the maximum pitch angle of the aircraft one second after and before touchdown exceeds a certain threshold. Specifically, we employ the LSTM model to make predictions of the maximum pitch angle with 22 parameters from QAR data. Extensive experiments based on a large-scale data show that the prediction model in this paper achieves the lowest MSE, MAE and the highest fitting coefficient R2-score, as compared to 9 traditional machine learning algorithms, which validates the effectiveness of our model in finding high risk flights.
