[Abstract]:With the further opening of China's low-altitude airspace and the rapid development of navigation, how to provide operational support services for navigation has been gradually concerned, and flight plan evaluation belongs to the category of operational support services. In this paper, the evaluation technology and realization method of navigable flight plan are deeply studied, and the design and implementation method of a two dimensional and three dimensional integrated flight plan evaluation system suitable for navigation in China are given. In order to provide technical support for the approval of navigable flight plan. First of all, this paper studies the evaluation method of navigable flight plan, analyzes the evaluation indexes, including vertical track profile, load balance, fuel consumption, meteorological conditions of the operating area, and determines the calculation methods of each evaluation index. An effective evaluation index system of flight plan is constructed, and the system flow is put forward for the evaluation of navigable flight plan in China. Secondly, in order to give the optimization scheme for the evaluated flight path, this paper studies the route optimization method of the navigable flight plan. By constructing the rasterized planning space, the maximum climbing / falling angle of the navigable vehicle can be obtained. The minimum track length, flight height and preset track point are introduced into the constraint model, and the traditional A * algorithm is improved from the search space, search strategy and heuristic function. A vertical profile track cost model suitable for China's navigable low-altitude flight is established. The weight coefficients of the track cost function are determined by using the analytic hierarchy process (AHP), and finally the route optimization of the navigable flight plan is realized. Finally, this paper gives the design and implementation method of the navigable flight plan evaluation system. The system is based on the U-GIS integrated geographic information platform, using the C / S (client / Server) architecture, the system is implemented under the Microsoft Visual Studio 2010 integrated development environment. Through the ADO data access technology to complete the foreground and background connection and operation, the main part of the code is implemented with C #. At the same time, the implementation methods of unit test, integration test and other test verification are given. The system operation and test results show that the system can provide an effective flight plan evaluation service for navigation. The flight plan evaluation system designed and developed in this paper has become an important part of the research and development of general aviation integrated operation support system, which is the key subject of the National Science and Technology support Program. Passed the National Ministry of Science and Technology acceptance on November 10, 2015, and will continue to improve in practical applications.
