Research on Climb Performance and 4D Trajectory Prediction of Aircraft

4D reckoning is a core technology to the next generation of air transport management. This paper mainly do research on the aircraft dynamics model under a given flight profile of different phases of flight performance and aircraft performance differences. Then, proposed two models: state switching transition model between different phases of flight, System evolution model under the continuous variation states that aircraft weight, indicated airspeed, altitude, distance and others. Using the mode of hybrid system recursive simulation obtained 4D trajectory of aircraft and analyzed the effects of various factors on the performance of the aircraft's climb.
