Instrument flight program three-dimensional design system

Abstract

The invention relates to an instrument flight program three-dimensional design system which is composed of a system basic data management module, an automatic flight program protection area two-dimensional generation module, an automatic obstacle evaluation module, an automatic flight program protection area three-dimensional presenting module and a database module. The automatic obstacle evaluation module can be used for calling data in the system basic data management module, achieving automatic obstacle evaluating on a generated flight program protection area, a navigation facility shielding surface and the like and sending an evaluation result to the automatic flight program protection area two-dimensional generation module to check whether the flight program protection area can keep the specified safety margin on obstacles. The automatic flight program protection area three-dimensional presenting module is used for conducting three-dimensional dynamic presenting on the flight program two-dimensional flight program protection area and the like. The instrument flight program three-dimensional design system can be used for achieving the functions of automatically generating the flight program protection area, automatically evaluating the obstacles and conducting three-dimensional presenting and perpendicular exaggerating on the flight program protection area and a high-precision mass DEM database and the like.

Description

Technical field

[0001] The invention relates to an instrument flight procedure three-dimensional design system, which is used for two-dimensional automatic generation, obstacle automatic evaluation and three-dimensional automatic presentation of flight procedure protection zones, and uses high-precision massive DEM data to verify flight procedure protection zone drawing in a three-dimensional environment The rationality and correctness of the results and evaluation conclusions belong to the field of computer application technology. Background technique

[0002] Flight procedure design is a method of planning approach and departure. The purpose is to straighten out the relationship between the route and landing or take-off. It is an important measure to ensure flight safety and prevent aircraft from colliding with ground obstacles. The flight safety of aircraft plays an extremely important role.

[0003] After the mid-1980s, with the development of CAD technology and electronic map...
