With the 1,500th enhanced vision system (EVS) recently delivered, Elbit Systems unveiled a number of developments as part of its ClearVision situational awareness enhancement range this week at NBAA 2014. Among the aims is to gain credits for landing with a 1,000-foot runway visual range (RVR), equating roughly to a 50-foot decision height.

Drawing on its commercial and defense equipment expertise, Elbit Systems announced a new six-sensor, multi-spectral EVS that maximizes detection capabilities by viewing in various spectral bands. These can be combined to optimize visibility and extract the best possible long-range detection capabilities through fog, rain, smoke, haze and the dark of night.

Meanwhile, its ClearVision EVS provides high-resolution imagery on a head-up display that can be combined with synthetic vision system (SVS) imagery and flight data symbology. This ClearVision combined vision system (CVS) can be configured in real-time in the cockpit, allowing the pilot to adjust the balance between EVS imagery and that from the SVS to best suit his or her needs and the prevailing light and weather conditions.
