Research On The Virtual Integrated Avionic Display Based On Personal Computer

With the rapid development of computer graphics technology,flight data instrumental visualization has become an important technical means of air-accident investigation and flight operational quality assurance.The technology of flight data instrumental visualization can reflects intuitively to relevant parameters in flight process in the form of instrument by virtual simulating aircraft operating conditions and instrumental display in cabin with the means of dynamic model.The demands of display content of integrated avionics display is analyzed in order to meet the needs of flight data instrumental visualization for a certain flight operation quality assurance,including state parameter and location parameter;the modeling technology based on FlightGear is researched in depth,and a model of integrated avionics display is built by software AC3 D based on object-oriented and top-down design;the description of system function and model driver is completed by using XML file,and the development of display part in navigation map is completed by using Canvas/Nasal system;finally,integrated avionics display is embedded in cabin,and the flight data file is loaded by external data I/O interface of FlightGear,and the flight state instrumental visualization is realized by the method of data-driver model.Designed Integrated avionics display is mainly based on primary flight display unit,and it can display attitude,horizontal situation,speed,altitude,engine parameter,atmospheric environment,airport information,navigation station in the form of integration.Simulation results show that an authentic and fluent interface can be displayed in integrated avionics display,which can reflect intuitively to the relevant parameters in flight process,and flight data instrumental visualization is realized.
