摘要

Hard landing is one of the several seriously dangerous potential events in terms of flight safety. The current process for deciding whether a hard landing has occurred is based on the subjective assessments by the flight crew. However, because of the lack of reliable quantitative data and accurate models, hard landing prediction is insufficient and pilots and aircraft crew are not satisfied with it, although there have been some researches on the landing safety problems. In this paper, we propose a new hard landing prediction model using improved PSO based-BP neural network. Related influence factors of landing safety are explored and the relevant flight data are collected in the research. As there are several influence factors, multicollinearity problem of input factors exists. Before establishing the prediction model, we first conduct principal component analysis. The BP neural network based on improved PSO optimization has higher accuracy than the BP algorithm, which can make the hard landing prediction model more precise. An empirical study is provided to confirm that the new method is effective.
