Design Of Synthetic Vision System Within Airborne Cockpit

Synthetic vision(SV)is a new cockpit display technology,developed in recent years.When flight,the external real-time environment of the aircraft can be displayed in the airborne cockpit display,using synthetic vision system(SVS),which can improve the pilot’s ability to environmental perception,reduce pilot’s burden,and improve flight safety and easy operability in case of poor visibility conditions.Considerable research was been done on this technology abroad,but very little domestic.This paper briefly introduces the concept,components and elements of SVS.This paper analyzes the technical requirements of the system development and recommends introduces terrain projection technique,3D terrain modeling method,three-dimensional route channel calculation and flight path forecast means.Meanwhile,this paper detailed discusses achievement process of various functions of the SVS,and superimposition on the SVS display with electronic flight instrument system.This subject uses a certain type of integrated avionics system for the application platform.The SVS was loaded into the cockpit display.Then,this paper used the GPS simulator and integrated avionics system testing equipment to simulate various sensors and send flight data,based on which this paper validated verified the functions of the SVS.From the result of validation,the functions of the SVS met the functional requirements of the AC 20-167 about SVS.
