Helicopter Pilots require Digital Night Vision Tech for Night Operations

Pilots rely more on vision than on any other sense to orient  themselves in flight. The visual sense is especially important in collision avoidance and depth perception. A pilot’s vision sensors are the eyes generally are most accurate and reliable sense, even though they are not perfect in the way …
