Aero Dynamix is the only NVIS provider who offers NVG Overlays for providing NVG compatible lighting to a group of instruments. This approach provides excellent, uniform NVG compatible lighting because the overlay projects light from 360° around each instrument. This is an excellent choice for providing NVG lighting to a cluster of instruments or an entire instrument panel if the aircraft has all analog instruments and gauges. Because light is dispersed in a 360° circle around each instrument using several lamps, dimming or shadowing is never a problem even if a lamp burns out. This is an ideal solution for instruments that have a high failure rate or require regular servicing or calibration because the unit remains in its original OEM condition and can be replaced by any TC approved component to continue NVG operations while the original component is sent in for repair or servicing. There is never any concern about where to send a unit for repair or servicing. Since the unit remains in its original OEM condition, it can be sent to any OEM approved repair center.
