21 Safety ConcernsCan the Pilot read all Instruments, gauges, switch labels, range bands, limitation marks, etc?
22 Safety Concerns Caution / Warning Panel – Legible, Workable Which Caution Lights are Lit?
23 Post Certification CMWhat happens after the aircraft is certified for compatibility with NVG?Configuration Management is CRITICAL for that aircraft.Removal, Replacement, or Installation of any equipment (internal or external) that could effect the NVIS lighting system requires a compatibility assessment.Who determines whether or not there will be an effect?Who completes the compatibility check-out?
