The original intent of masking these lights was to prevent disruptive glare during night vision goggle (NVG) operations. However, these masking practices were in violation of FAA regulations when aircraft were operated in national airspace at night. Once the masking was removed, an unacceptable level of glare persisted for aircraft operators using NVG. The aeromedical research laboratory developed a masking scheme in compliance with FAA regulations and NVG user\u003cbr\u003erequirements.","brand":"www.survivalebooks.com","offers":[{"title":"Default Title","offer_id":47171178889456,"sku":"2940013623026","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013623026","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
