摘要

Trajectory based operation is an important part of future air traffic management research field, which needs Negotiation and Validation between Flight Management System and ground based 4D trajectory planning. Thus, ground based 4D trajectory planning is the foundation to implement trajectory based operation. And a combination of aircraft kinematics model and meteorological model based 4D trajectory planning method was presented. Firstly, historical radar data was analyzed by big data processing method upon which a horizontal path could be designed and altitude, speed ranges could be determined. Secondly, based on the selected horizontal path a 4D trajectory was planned with the application of combination of aircraft kinematics model and meteorological model based 4D trajectory planning method. Finally, taking arrival flights to Shanghai Pudong Airport from PINOT entry fix as examples, a simulation was conducted. And the simulation result indicates that the proposed 4D trajectory planning method can generate reasonable 4D trajectory, provide reference trajectory for airborne flight management system (FMS), accelerate the implementation of trajectory based operation, reduce flight delays, and improve the operational efficiency in terminal airspace.
