EVS vs NVG: Both better
The adoption of infrared imaging enhanced vision systems (EVS) in rotary-wing applications has been slow because of a common misconception, that night safe

The adoption of infrared imaging enhanced vision systems (EVS) in rotary-wing applications has been slow because of a common misconception, that night safety is an “either/or” choice between EVS or night-vision goggles (NVG). So suggests Chuck Crompton, business development director for Lexavia Integrated Systems, Pensacola, Fla., adding that using the two technologies in combination may provide the best of both possible worlds.

Many professional helicopter pilots are retired military with previous extensive NVG training, he said, and could be expected to prefer NVGs to deal with the risks of night operations. Lexavia (Booth No. 3333), relatively new to the EVS marketplace, and Max-Viz (Booth No. 4408), a pioneer in lower-cost EVS with uncooled IR cameras, are both at Heli-Expo championing complementary use of EVS and NVG for night helicopter operations.
