1.What is the function of MH Aviation Night Vision Goggles?
Helicopter operators worldwide increasingly are implementing night vision imaging system (NVIS) operations to improve safety margins through greater visibility at night. ANV-9 enable flight crews to better see obstacles, terrain and developing weather, contributing to greater situational awareness and reducing stress during nighttime flight. ANV-9 operations significantly reduce the risk of visual night operations compared with the same operation conducted unaided.
2.What is the difference between ANV-9 pilot-specific aviation night vision goggles and general night vision goggles?
The most obvious difference between pilot-specific aviation night vision goggles and general night vision goggles is that the objective lens is coated with special C film for aviation equipment, so that pilots can clearly see the targets outside the aircraft during night flight operations (or other periods of reduced visibility). And more importantly, it is to be able to see the data on the brighter instrument panel clearly, without the need for repeated wear, allowing the pilot to quickly and continuously obtain sharp visual perception and better image acuity, which is critical to the success of the pilot's mission.All of Accessories includes: pilot night vision goggles, bracket for ANV-9 pilot helmet (support for customized bracket), battery box, clean cloth , safety box.
