Conflict automatic identification method and device for PBN instrument flight program in terminal area

Abstract

The invention relates to a conflict automatic identification method and device for a PBN flight program in a terminal area. The method comprises the steps that the route data of all route segments are read; all route segments are traversed to extract route segments with intersections and search the intersections of intersecting route segments; the height of two endpoints of two intersecting route segments is deduced respectively; whether the distance between two intersecting route segments at the intersection is less than or equal to a set threshold is determined; and if the distance is less than or equal to the set threshold, a conflict is identified, otherwise no conflict is identified. According to the method and the device, which are provided by the invention, the working efficiency of a programmer can be greatly improved; the workload of the programmer is reduced; the man-made error rate is reduced; and the visualization of the flight program can directly and promptly provide the control personnel with reference means of potential conflict analysis.

Description

technical field [0001] The invention relates to the technical field of air navigation service flight program design, in particular to a method and device for automatic conflict determination of PBN flight programs in a terminal area. Background technique [0002] The increase in air traffic has made large air traffic control terminal areas increasingly busy and congested. In the airspace of the terminal area, the aircraft is usually in the flight state of climbing or descending, which increases the complexity of the airspace in the terminal area. In the environment of high-density traffic flow, it is very important to ensure the traffic safety of the complex airspace. The relevant departments of the Civil Aviation Administration of China are facing the problem of how to ensure flight safety while ensuring flight service quality, and the large terminal control area is more urgent. [0003] As the core content of airspace planning, a sound PBN (Performance Based Navigation) p...

Problems solved by technology

In addition, in China, most flight program designers lack actual operating experience. In order to comply with flight program design standards such as gradient of climb (ROC) or gradient of descent (ROD), many potential control conflict nodes or segments are often created, making the program The mismatch between the design and the needs of the controllers increases the difficulty of the handover of the aircraft by the air traffic controllers, and uses many additional control intervals in the command process that could otherwise be avoided, increasing the workload of the controllers

At present, these potential conflicts can only be manually analyzed and checked one by one. This work is not only time-consuming and labor-intensive, but also the probability of errors and omissions will increase due to the increase in the number of flight procedures.
