英文摘要： Continuous Descent Approach (CDA) Methodology is the advanced landing technology which ICAO and European and American strongly research on at present. The theory and techniques of CDA are studied in this task; the techniques will be involved in searching set of columned gridding. At same time the kernel algorithm of approach tracks are be constructed using the theory and techniques. And then the optimizing methods of 4D trajectory profile are shown with modified terminal area multi-location signals and refresh data domain based on PBN. By the key parameters consistent testing such as the Top of Descend (TOD) etc. , the evaluation algorithm for the CDA trajectory based on PBN is explored. And the optimizing fusion model of optimization descent trajcetory is illustrated with the descent track profile data using PBN. At last, the practicable CDA trajectory creation system and demonstration system is established. The research results can be used as concept foundation of terminal approach landing program designs for the airports applications. The research contents include: the basic concept of CDA and CDA program design algorithm based on PBN; the constructing algorithm for the columned gridding set and columned gridding set searching algorithm for the dynamic CDA routing layout based on PBN; the evaluation algorithm
