Research On The Three-dimensional Model For Airspace In Multi-airport Terminal Area

Recently, with the ecomomy’s rapid development, the civil aviation has been developed greatly. On the one hand, the number of airports is increasing greately,it is common that one metropolis may have two airports or several ones; on the other hand, the air traffic flow has grown greatly, the air traffic congestion has been a common phenomenon. However, for the multi-airport terminal area, it includes the intense airports, complex airspace and heavy traffic, which greatly restricted the air traffic operation.As a result, studying a scientific and efficient multi-airport cooperating model has been a key to solve the problem of multi-airport terminal area.Under the above background, this paper established the three-dimensional model of the airspace in multi-airport terminal area. Firstly, it analyzes the airspace structure, operating characteristics and constraints in the multi-airport terminal and then introduce the airspace’s resources. Secondly, after analyzing the mode of operation in multi-airport terminal area and studying the airspace resources and time resources in multi-airport terminal area, it established the relation between airspace resources and time resources. Based on the relation, it establishs a the three-dimensional model of the airspace and get a terminal’s resourses by using the AutoCAD.And the Simulation results in Zhuhai terminal show that the above Space-time three-dimensional model can be used to achieve a better optimized result.
