Synthetic Vision Systems (SVS) are designed to improve pilot’s situational awareness, thus lowering his workload. Synthetic Vision provides virtual out-of-window view of terrain and obstacles irrespective of weather conditions. SVS uses terrain databases and onboard sensors as inputs to render out-of-window cockpit view to the pilot. The dependability of synthetic vision is related to the accuracy of terrain elevation database and navigation data such as Differential Global Positioning System, Radar Altimeter etc. Sensors such as Radar Altimeter, Weather Radar can be used to monitor the integrity of the terrain databases. This paper provides an overview of SVS, sensors required to improve the reliability of such a system. A study of critical technologies such as synthetic database, flight symbology and display systems have been carried out. Tunnel in the sky symbology used in SVS displays have been studied. Accordingly, recommendations have been made regarding HUD FOV, accuracy and resolutions of synthetic database. A survey has been carried out regarding commercial SVS products that are available with state of art technology.
