摘要
The method includes generating flight plan trajectory based on a flight plan, generating a predicted trajectory based on flight plan and flight data, Calculating a trajectory position error of the aircraft with respect to the predicted trajectory based on the trajectory data collected in real time; Comparing the trajectory deviation reference set with reference to the predicted trajectory and the trajectory position error to determine whether a new predicted trajectory is generated; And generating a new predicted trajectory according to a result of the determination and updating an existing predicted trajectory or maintaining an existing predicted trajectory, wherein, when calculating the trajectory position error, The planning position error corresponding to the positional error of the current trajectory with respect to the planned trajectory is calculated and compared with the planned positional deviation set based on the follow-up plan and the planned position error before comparison of the trajectory deviation reference and the trajectory position error Further comprising the step of changing an existing follow-up plan to a new follow-up plan according to a comparison result of the planned position error, wherein when the distance between the flight plan trajectory and the trajectory is within a predetermined standard, If the plan is changed to a follow-up plan and the distance between the flight plan trajectory and the wake is outside a certain standard, To find an alternative plan to change the plan to follow-up plan, it is the aircraft trajectory prediction method.;
