4D Trajectory Prediction for Arrival and Approach Phases of Flight

4D trajectory prediction is the central part of many automated decision support tools of the future air traffic management systems. It is used to calculate, in advance, where exactly the aircraft is going to be at each point in time, therefore, allowing potential conflict resolution and route negotiation before the aircraft even takes off. Trajectory prediction relies heavily on aircraft performance calculation which must be somewhat simplified in order to facilitate fast computation of thousands of such routes, but not overly so that it becomes inaccurate. Aside from performance calculation, accuracy of trajectory prediction depends on correct representation of aircraft operation. Therefore, accurately modelling the flight management system is essential to trajectory prediction. This paper considers several possible improvements in flight management system model, mainly in bank angle setting and lateral guidance. Due to many changes in altitude and heading, as well as in thrust and attitude of the aircraft, one of the hardest phases of flight to predict is the arrival phase. Since one of the major goals of trajectory prediction is arrival queue management, this paper focuses on accurately predicting 4D trajectories during the final phases of flight. This paper also deals with conflict resolution and queue management in final phases of flight.
