A Descent Stage Trajectory Prediction Method Based on Multi-objective Constraints
In order to improve the aircraft trajectory prediction accuracy,considering route restrictions,cost index and aircraft performance restrictions,a multi-objective constraint-based aircraft descent flight trajectory prediction method is proposed.According to aircraft performance data,characteristic parameters,route restrictions and cost index requirements,dynamics theory is used to dynamically analyze and predict multi-dimensional state data for each flight sector.The take-off,climb and cruise data of a real trajectory in the aircraft data recorder are used to predict and optimize its descent trajectory.The simulation results show that,compared with the real trajectory,the predicted trajectory and multi-dimensional status data are dynamically adjusted with the cost index and the constraints of the route,which meets the route restriction and improves the fuel efficiency.
