The MD41-628 is a self -contained GPS Annunciation and Control unit. It combines all the necessary functions required for switching HSI/CDI data inputs between a conventional NAV (VOR) receiver and the Trimble 2000APR, 2000APR PLUS, 2101, 2101 PLUS, 2101 I/O, 2101 I/O PLUS and AN/ASN-175 approach-certified GPS receivers. In addition, the MD41-624 contains a GPS/NAV status annunciation used to indicate the mode selected by the front panel switch. Also various inputs from the GPS receiver are annunciated on the front panel.
A special ILS override feature has been incorporated to cause the MD41-628 to automatically switch to the NAV mode when the NAV (VOR) receiver is tuned to an ILS frequency. Other features include dual, 16,000 hour lamps used for all annunciations, internally lighted selection switches, automatic photocell dimming, and built-in annunciation self test. A external annunciation dimming adjustment is provided for balancing low level light conditions
