Abstract
With economic growth, the civil aviation industry in China has developed rapidly. However, the previous structure and distribution of airspace is unable to meet the expanding demands of traffic growth. Serious congestion, busy airspace, and unsafe events are the major problems facing airports. The tension of airspace blocks the development of the civil aviation industry seriously; therefore, the use of optimal available airspace is urgently needed. To solve this problem, the Civil Aviation Authority of China urges the development of PBN (Performance Based Navigation) to make sure the navigation technology is used widely in the country. The utilization of PBN improves aviation safety, increases the capacity of airspace, and reduces the costs of construction and maintenance of ground-based navigation facilities. In general, the first step of designing a PBN flight procedure is to figure out the parameters of each flight phase's protected areas. Then, according to the corresponding parameters, AutoCAD should be applied to draw the procedure, which is cumbersome and error prone and needs to be modified repeatedly and comprehensively coordinated and optimized. Actually, the structures of protected areas in different PBN flight procedures are similar: the only difference lies in the sizes of parameters, and the graphic will change accordingly. There are few studies of PBN flight procedure automation so far, this paper uses AutoCAD's embedded language, AutoLISP, which possesses the fundamental structure and function of the general high-level language and also has a powerful graphical processing function, to write a program, and the automatic generation of PBN procedure can be realized only by changing the name of the file and assigning the different values for parameters. This kind of procedure avoids the tedious work in interactive mapping and solves the difficulties in PBN procedure designing; it has a valuable reference for the subsequent automatic development of the PBN program designing.
