The application of Boeing 787 and other new types of civil aviation aircraft put forward new requirements to the cockpit integrated virtual display system of training simulator.In order to meet the requirements that the display can be switched,recombined,transplanted with more information and more flexible display mode,the characteristics of the new display system were analyzed,and a development process was proposed based on virtual instrument component library.The display interface was developed by using VAPS,and the data interface,communication links and communication protocols were established.A virtual simulation integrated display system for Boeing 787 was designed based on the development process,which can meet all the requirements.The study supplies the development process,modular material library and communication protocols for the future development of virtual instrument.
