Research of a general approach to design aeronautical virtual instrument system with low cost

A general approach to design aeronautical virtual instrument system with low cost was introduced, of which the detail implement scheme was provided as well. The system connected with other systems through RS232 communication interface was designed and wrapped with object oriented programming method based on Graphic Device Interface (GDI), differently in terms of different requirements, then used in kinds of engineering applications as COM component, which made the observation to data more intuitionistic. This approach with general features is simple to implement, easy to use, besides, whose idea can be used in different developing and running platforms.
