The Analysis Of Terminal Aerospace VOR/DME Based Flight Procedures

With the rapid economy development in China in recent years, the number of flights has been steadily increasing to meet the market demand, and the terminal airspace becoming much crowded. As a result, a safe, economic, simple, and efficient flight procedure is needed in order for the airplanes to fly safely and orderly over terminal airspace. However, at present in China civil aviation industry, the flight procedure design for terminal airspace is still in its early stage, with existing problems, such as too many navigational aids, inefficient use of navigational aid frequency, and low adaptability of flight procedure. Therefore, it is critical and very important to research on VOR/DME instrument-based flight procedure design for terminal airspace. Such research can lead to a new flight procedure design methodology, which copes with these problems and makes strong economical senses.Under the guidance of aviation safety, efficiency, regularity and economy, this thesis applies the principle of the instrument flight procedure, firstly, to research the current VOR/DME instrument flight procedure, namely the VOR/DME instrument flight procedure (VOR/DMF. IFP), its holding procedures, departure routes, arrival routes, and approach procedures, Cor the terminal airspace. Secondly, this thesis investigates the designing methods for VOR/DME-based area navigation flight procedure (RNAV FP). Thirdly, this thesis compares these two different natures of flight procedures to further extend, and the possibility of RNAV FP based on the principles of VOR/DME IFP is studied. In the end, as a case study, these two Flight Procedures are set up at GuangHan terminal airspace, and the comparison is made between these two methods to illustrate the advantage and disadvantage of each method. Based on the research of this thesis and the case study, the thesis provides a new method of designing terminal airspace flight procedureand gives useful and valuable suggestions and recommendations for the selection criteria of VOR/DME IFP and RNAV FP for the same location of VOR/DME, to flight procedure designers and related personnel.
