NAV-4000/4500/VIR-4000/ADF-4000 Navigation Receivers


The Rockwell Collins NAV-4000/4500 integrated navigation receivers are members of our Pro Line 21 CNS product family. The NAV-4000 incorporates the VOR/localizer, glideslope, marker beacon and ADF receivers into a single package. Our NAV-4500 is intended for installations offering a single ADF receiver as standard with a dual ADF receiver as an option. It is identical in size and pinout to the NAV-4000 but excludes the ADF receiver.

For new installations, high-speed interfaces with a radio interface unit enable features such as software data loading, enhanced maintenance reporting, digital audio and data communications management. The NAV-4000/4500 also maintain the Pro Line II and Pro Line 4 serial data and analog audio interfaces, allowing them to fit into existing installations with minimal aircraft modification.
