Study Of General Aviation Flight Data Processing Method Based On FIXM

The existing air traffic control and flight data service management system,such as air traffic control radar,cannot fully cover general aviation,due to the general aviation flights' wide range,low flying height and flexible flight activities.And the general aviation flight plan application,monitoring and operational services development were not developed.These problems have become important obstacles to the rapid development of general aviation in China.In this background,this dissertation studied the general aviation flight data processing method.It mainly completed the following works:Firstly,based on several typical general aviation operating unit launches the research to understand their operational mode,and the aviation operation data used in the process of operating,and have a detailed analysis of data format,data standard and source of data.Then the pattern matching algorithm of regular expression was used to deal with these data.Secondly,the data of general aviation operation was defined as the research object.Compile the FIXM DD according to the analysis of aviation operation data.By using unified modeling language(UML),this dissertation established the FICM,FIXM logical model and FIXM extension model.The construction of the FIXM produced the flight object data(FOD),and also provided the theoretical support for the analysis of the general navigable flight data for the FIXM.At last,the analysis of flight data was realized through Qt platform programming.On the basis of verifying the feasibility of the FIXM,the navigation flight data processing system was developed.The operation result of the system verified the readability and accuracy of the FIXM model simply and intuitively in the processing of navigable flight data.The establishment of the FIXM and the development of the navigation flight data processing system provide a new platform for the transmission,exchange and sharing of navigation flight data,which was conducive to the better development of China's general aviation industry.It also served a model for the construction and implementation of our country's SWIM in the near future.
