QOS is developing an Enhanced Vision System (EVS) that combines image enhancement and synthetic vision elements to assist pilots flying through adverse weather conditions. This system uses a combination of forward-looking infrared and visible sensors for data acquisition. A core function of the system is to enhance and fuse the sensor data in order to increase the information content and quality of the captured imagery. These operations must be performed in real-time for the pilot to use while flying.

EVS-3ch facilitates precision approaches and safe landings in reduced visibility conditions, including thick fog, smog, heavy rain and snow. EVSs operating bandwidth in short and long IR spectrum to provide clear images of approach and runway lights, runway threshold, buildings, other visual cues, obstructions and aircraft in close proximity. These images normally are undetectable to the pilot's naked eye at night and in bad weather.
