The general geographical environment of high-altitude airports and meteorological conditions are very complex, large temperature difference between day and night, wind speed, wind direction changed, often accompanied by severe turbulence and wind shear, rapid weather changes. An average elevation of China's Qinghai-Tibet Plateau, has been built and plans to build the airport environment is very complex, the typical airport Tibet / Lhasa airport, Tibet / Nyingchi Airport, Sichuan / Jiuzhaigou Airport. With the development of China's economy, the strategic significance of the western region is increasingly important China is gradually promote the development and construction of the western region. In order to improve the transport and logistics plight of the western, great efforts to build the airport in the western area. Due to the inherent characteristics of the high-altitude airports, high altitude flight and operation compared with the low-altitude airport, facing more and more complex problems. In order to ensure the safe operation of the altitude airport, the Civil Aviation Administration of China is making great efforts to promote the application of new technologies of Civil Aviation. Among them, the Global Navigation Satellite System (GNSS) and performance-based navigation (PBN) is the technology of choice to solve the difficult operation of the high-altitude airports. In this paper, the operating environment of the high-altitude airports, satellite navigation technology, PBN technology introduction, analysis and research on the best ways and solutions solve the plateau Airport in Lhasa, the future the plateau airport navigation application of new technologies made anticipation and foresight. The pilot during the flight personnel, the training time, flight data subjects, ensure the safety of training, the the retrospective training process, analysis of the effectiveness of training is very important, need to be recorded and analyzed in detail. Traditional flight training in data management is usually recorded by hand method, which record high error rate, low statistical efficiency, data sharing difficulties. In order to improve the accuracy of the basic flight data management, timeliness and data sharing, this paper developed the basic data management system based on B / S structure flight information. System using Browser / Server architecture, select SQL Server 2000 as the back-end database system, pilot information management, the flight instructor information management, time-of-flight management, the flight account management, system management, and other functions. Flight authorities can achieve accurate flight data management and analysis through the system, and as a basis for adjusting the flight plan, identify potential risks to improve the quality of flight, strengthen safety management and other purposes. In this paper, the following aspects: (1) analysis of high-altitude airports, high-altitude airport operating environment, including the natural environment, weather conditions, navigation facilities, obstructions characteristics, focusing on research and Highland complex run the impact of the environment on the flight operations; (2) analysis of the traditional ground-based navigation system navigation and positioning error characteristics, focusing on the characteristics of the the plateau airport land-based navigation system limitations and errors; (3) issued by ICAO PBN Manual , \) PBN run the core navigation system, satellite navigation system works, characteristics and error characteristics, focus on GPS navigation accuracy, integrity issues, the field of application of different types of satellite navigation augmentation systems and phases of flight; ( 5) analysis of the climatic characteristics and geographical conditions of the Lhasa airport ground support conditions, PBN run the navigation conditions, airport operations access requirements and design requirements for PBN operations to determine the aircraft selection, design PBN navigation to run the program (including track longitudinal and transverse view of) the PBN implementation process running, by running the practice of statistics and analysis, to prove its feasibility; (6) sets out to establish the need for flight information management system; introduced C / S, B / S software architecture and describes the feasibility of the system uses B / S software architecture; analysis and flight information in accordance with the relevant characteristics of the specific needs of basic data management system, select SQL Server as the database platform; (7) function of the system module design, program flow design, database structure design, network topology design, demonstration flight information management system for the operation of the module interface.
