| Abstract: | In order to evaluate fuel consumption of air traffic control in terminal area effectively,combined with a comprehensive trajectory data using data mining technology,estimated airspeed model of terminal area on comprehensive trajectory data is proposed.Firstly,trajectory data processing is proposed to processing method;By taking over meteorological data of the airport,wind field model over the airport is established by interpolation method;Analyzing sailing speed triangle airspeed calculation model was deduced.At last,the QAR data of departure and approach are used to simulate and estimate the true airspeed.The results show that the method based on comprehensive trajectory data can be used effectively to estimate the true airspeed. |
