Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should understand that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand the present invention Modifications in various equivalent forms fall within the scope defined by the appended claims of the present application.

[0020] The invention provides a method for correcting the predicted track of the aircraft plan by monitoring data. During the implementation of the planned track of the aircraft, the following four aspects can be used to correct the forecast model and results, which can greatly improve the accuracy of the planned track of the aircraft.

[0021] (1) Takeoff time correction based on empirical takeoff time:

[0022] Due to the deviation of the predicted trajectory due to the...

Abstract

The invention provides a correction method of an aircraft plan prediction locus by using supervision data. Through correction of an empirical launch time which is dug based on historical flight plan data, correction of the prediction locus by using a point-crossing time, correction of the prediction locus by using a point-crossing position, and correction of the prediction locus by using an instruction height, an effect of accurately correcting the aircraft prediction locus can be achieved.

Description

technical field [0001] The invention relates to a data correction method, in particular to a correction method for aircraft planning and forecasting trajectory. Background technique [0002] The planned and predicted trajectory can enable air traffic controllers and flight service related functional departments to grasp the dynamics of the aircraft in advance, and the accuracy of the planned and predicted trajectory will greatly affect the feasibility and effectiveness of decision-making. In the current field, the generation of the planned forecast trajectory is calculated by building an aircraft performance model, but there are certain differences between the predicted results and the actual operation results. If the planned forecast trajectory can be applied and implemented, auxiliary corrections must be used. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] Aiming at the problems and deficiencies in ...
