Night Vision Goggles in Civil Helicopter Operations


Night Vision Goggles (NVGs) are binocular devices that enhance unaided night vision for pilots. Typically, NVGs are mounted on a pilot's helmet. This position enables pilots to look through the goggles outside the cockpit or under the goggles at flight instruments. By enabling the pilot to see in the dark, NVGs have the potential to improve the safety of visual flight at night. In most conditions, night vision goggles provide pilots with a significant increase in the quality of visual information compared with unaided night vision. They allow the pilot to see the horizon, objects, terrain and weather more easily. Furthermore, they assist the pilot to maintain spatial orientation, to avoid hazards such as inadvertent Instrument Meteorological Conditions (IMC) entry, and to visually navigate.
