Method and apparatus for determining whether an aircraft has passed a target waypoint

Abstract

The invention relates to the field of aviation management and especially relates to a method and apparatus for determining whether an aircraft passes through an object route point. The method comprises the following steps: comparing the length of a front route segment and a rear route segment of the object route point; arranging a standard point on the longer route segment from the front route segment and the rear route segment of the object route point, wherein the distance from the standard point to the object route point is equal to the distance from the object route point to the shorter route segment; obtaining a first distance from a current position of the aircraft to the standard point, and obtaining a second distance from the current position of the aircraft to the other endpoint of the shorter route segment; and comparing the length of the first distance with the length of the second distance, and according to a comparison result, determining whether the aircraft passes through the object route point. According to the embodiments of the invention, whether the aircraft passes through the object route point can be accurately determined and accurate time when the aircraft passes through the object route point can be obtained accordingly, such that the air traffic flow can be predicated, flight safety is guaranteed, and the utilization rate of spatial domain resources and the operation efficiency of an airport are improved.

Description

technical field [0001] The invention relates to the field of aviation management, in particular to a method and a device for determining whether an aircraft passes a target waypoint. Background technique [0002] With the rapid growth of air traffic flow, the degree of congestion in the airspace has also increased greatly, leading to serious flight conflicts in the air. If the air traffic flow can be accurately predicted and early measures taken for congested airspace, not only can flight safety be guaranteed, but also To effectively utilize airspace resources and improve airport operation efficiency, how to accurately predict air traffic situation has become a technology that is more concerned in the field of air traffic control. [0003] An important technology in predicting the air traffic situation is how to accurately determine whether the aircraft has passed the target waypoint. Accurately determining whether the aircraft has passed the target waypoint can assist the a...

Problems solved by technology

In the prior art, the aircraft generally flies according to the predetermined route plan. However, when the aircraft is greatly affected by the ground airflow, the flight track changes more drastically, and the aircraft will also be subject to human factors during the execution of the flight plan. These factors have It may cause the aircraft to fly out of the planned route, so that the aircraft cannot accurately determine whether the aircraft has passed the target waypoint during the flight, and thus cannot accurately predict the air traffic situation, thus affecting the safe flight of the aircraft
