Computer Aided Design Of Flight Procedure Protected Airspace In 3D Environment

With the vigorous development of civil aviation in china, demand of flight procedure design is increasing rapidly. As a relatively complex stage in the whole work, process of draw and generate flight procedure protection area, which need more efficient. Flight procedure auto-design is becoming a hot issue. The success of 2D automation design in other fields can be used as a good reference, while the automation method of 2D design cannot meet the demand of civil aviation. It's important to realize 3D visualization of flight procedure protected airspace by software and mathematical modeling.This paper achieved a flight procedure protected airspace aided system by combine a variety of mathematical algorithm and block design method for graphic structure with advanced software technology, which include:1. Design system and architecture according to the demand of flight procedure protected airspace division and the characteristics of the development platform. Develop a variety of flight procedure protection models, and all these models could be widely apply in other types of flight procedure protected airspace modeling;2. Summarize the characteristics of different flight procedure protected airspace though analysis elements of graphic structure. Design mathematical model of different flight procedure protected airspace though some algorithm and connect different part of flight procedure, laying the foundation for data classification of protected airspace.3. Developed a practical flight procedure protected airspace aided design software which could realize function of generate data combined by a variety of programming techniques.Verifying the feasibility of computer aided design of flight procedure protected airspace in 3D environment by simulating three-dimensional in the third-party platform.Finally the design achieved a practical aided design system for flight procedure protected airspace, complete 2D design and visualization of 3D by an efficient calculation function,provide a new method for 3D protected airspace.
