Abstract
Abstract
Due to the various meteorological conditions encountered in the flight process, the uncertainty of FT will change. In order to obtain the FT error, the secondary surveillance radar and aviation weather forecast data are used for analysis. According to the propagation mechanism of uncertainty, an adaptive prediction model of FT uncertainty is established. The input parameters of the adaptive model include Mach number, flight distance, vector wind and temperature. Cluster analysis and linear regression analysis are used to analyze the accuracy of the model. Compared with the static time-of-flight prediction model, the dynamic time-of-flight prediction model can accurately predict the FT even if the weather conditions are very bad. The dynamic time-of-flight prediction model is applied to air traffic management to further test the accuracy of the model. The results show that the adaptive time-of-flight prediction model based on meteorological conditions can accurately predict the arrival time of a flight to a certain waypoint.
