Aircraft operation visualization method

Abstract

The invention provides an aircraft operation visualization method based on a four-dimensional space-time grid, and the method comprises the steps: determining the minimum side length of an earth surface two-dimensional plane grid, building an earth surface subdivision grid system facing aircraft operation, carrying out the subdivision and coding of the grid height, carrying out the two-dimensional plane grid representation of an aircraft operation route, constructing a four-dimensional space-time grid for aircraft operation, and coloring the four-dimensional space-time grid; according to the method, the four-dimensional space-time information of the aircraft can be visually and integrally displayed on the display screen, four-dimensional state visualization in the flight process of the aircraft is achieved, a controller can conveniently know the position and the operation time of the aircraft in time, visual, dynamic and comprehensive aircraft operation state display can be provided for the controller, the controller has a global understanding of the flight dynamics of the aircraft in a future period of time, and the flight safety is better ensured.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, in particular to a grid-based aircraft operation visualization method. Background technique [0002] With the rapid development of the national economy, China's civil aviation industry has also ushered in a period of rapid development in recent years. As of 2020, China's civil aviation passenger traffic has ranked second in the world for 15 consecutive years. The rapid development of civil aviation has greatly increased the flow of air traffic. In order to ensure the safety of civil aviation flight, it is necessary for the flight controller to keep an eye on the operating status of the airborne aircraft on the display screen. [0003] The current method of characterizing aircraft operation is to predetermine the starting point, turning point and ending point in the route planning process, where the connection between the starting point to the turning point, the turning point to th...

Problems solved by technology

Since the spatial position of the aircraft in the air is constantly changing over time, the operational situation of the aircraft needs to be characterized by both the time dimension and the spatial dimension. The current method of characterizing aircraft operation in the flight management system is in two dimensions (horizontal plane) or Three-dimensional (horizontal plane + altitude) characterizes the operating state of the aircraft, and it is difficult for the flight controller to visually see the four-dimensional operating state of the aircraft and the moment when the aircraft runs to each point through the display screen in real time.
