Design And Implementation Of Rnp Navigation Technology Training System

Sichuan airline company is located at the southwestern of China, which takes a considerable proportion of airports in western of China, and some plateau and special airport flight operation environment are complex,airport security facilities are insufficient, there are many obstacles near region and climb/overshoot regional geography environment,some airports meteorological conditions are complex and changeable,some airport ground helps the navigation equipment or navigation equipment incomplete or bias. So the flight safeties constitute potential risks.PBN (Performance Based Navigation)technology can provide precisely the vertical and horizontal leads, guiding and traditional navigation technology, the pilot have to rely on the navigational facilities which will guide the plane to fly following the accurate position under poor visibility , and if the technology of PBN is being used, the conditions of security and accurately and flight safety standards of accuracy will be greatly improved. However,RNP( Required Navigation Performance ) navigation technology in the country is still at an elementary stage, only a few of the airport in foreign companies to adopt RNP navigation technology for the plane in the past and departed to RNP flying skill of navigation is not enough, especially in RNP route design of the program was almost zero, RNP navigation flying skill training has not been expanded.We first review and RNP navigation technology research and analysis of navigation technology RNP into the relevant principles, including the relevant concepts RNP, classifying RNP into the category, RNP programming standards, the merits and demerits of RNP navigation technology. based on this combines software engineering, developed RNP navigation technology training system, the system uses the client server mode, with the functions of system management, users info management and RNP principle of landed and departed, the abnormal RNP procedure example, training, management and analysis of the system stops the news of the receiving management; the functional modules are independent, which satisfied the ideal of "high cohesion low coupling", and some test technical and detailed of the unit testing process are introduced. RNP navigation technology training system introduced RNP principle, and programming for the implementation of the airport and the pilot RNP provided a technology and knowledge of the state training platform RNP navigation technology standards have positive significance.
