Analysis of Flight Trajectory Model Based on BADA

Abstract

AbstractThe aircraft trajectory model is a fundamental constraint of aircraft trajectory planning. An appropriate trajectory model can make trajectory planning faster and make the resulting trajectory more practical. Although the Base of Aircraft Data (BADA) is one of the most widely used aircrafts performance data base, in BADA, there are few details on how to use BADA to calculate trajectories and how to explicitly handle the acceleration in climb and the deceleration in descent. To solve the problem, this paper first analyzes the influencing factors of the trajectory model based on BADA, making the model available for different scenarios and different kinds of aircraft. Moreover, since the whole flight trajectory is achieved by a series of aircraft maneuver modes, we study the correspondence between different maneuver modes and three control modes of the trajectory model. In this way, flight trajectories can be calculated by selecting an appropriate control mode. Numerical testing results show that all practical aircraft maneuver modes can be realized by applying three control modes, according to the correspondence between them.KeywordsTrajectory planningTrajectory modelControl modeManeuver mode
