Description / Abstract: This document contains Minimum Operational Performance Standards (MOPS) for the aviation night vision imaging system (NVIS) used to supplement night VFR operations. NVIS consists of the night vision goggle, interior and exterior lighting, cockpit transparencies and crew station design and components. Performance and test procedures are provided for the night vision goggle and lighting. A section on continued airworthiness contains guidance to ensure the integrated NVIS equipment installation continues to meet the minimum performance standard once in operational use.
