Problems solved by technology

At present, this technology has been widely used in Europe, but it is still in the stage of theoretical exploration in China. Some scholars have started to study and explore the feasibility of its implementation and application in my country, and design point fusion procedures and flights based on point fusion procedures for specific airports. However, most of its design is based on theory, and how to combine it with actual traffic flow operation to optimize the design has just started

Abstract

The invention discloses an aircraft approaching 4D flight path planning method based on a point fusion program. The method comprises the following steps: S1, designing the point fusion flight program;S2, evaluating the point fusion flight program; S3, optimizing a point fusion program static structure; S4, constructing a point fusion program 4D approaching trajectory planning model; S5, generating a point fusion program 4D dynamic track of an approaching flight. According to the invention, on the premise that safe operation of flights is guaranteed, the method increases the terminal area approach route capacity, reduces the operation cost of the aircraft, and reduces the environmental influence.

Description

technical field [0001] The invention belongs to the technical field of 4D track planning for aircraft approach in a terminal area, and relates to a method for planning an approach flight operation in combination with a point fusion approach program and an operating condition in a terminal area. Background technique [0002] With the rapid development of the global economy, the air transport industry is developing rapidly. However, with the booming air transport industry, flight traffic has surged. The terminal area is an important connection area between the airport flight area and the air route, and its flight congestion occurs frequently, causing unnecessary circling and waiting in the air, ground delays, increased operating costs, and increased the additional workload of air traffic control personnel and crews. burden, seriously endangering air traffic safety. How to strengthen flight management in the terminal area, ensure the safety of aircraft, increase the capacity ...
