INS 422: Integrated Navigation System
The ultimate "All in One NAV System" with GLIDESLOPE, LOCALIZER, VOR plus 3 LIGHT MARKER
The INS 422 is a high quality, multi-function, fully integrated navigational instrument designed as a complete, stand-alone unit, supplying four basic navigational aids: VOR with digital course select and Automatic Radial "TO" Centering feature, Localizer, Glideslope, and Three Light Marker. The units digital display well define the CDI indications. CDI output data is also available at the rear connector for easy interface with most Autopilots. Aluminum construction offers a lightweight yet very durable unit, which will provide years of reliable service. This instrument mounts in a standard round 3.125 inch mounting hole.
Automatic Radial Centering To determine the bearing TO a VOR station with conventional course indicators, it is necessary to manually rotate the OBS to center the course deviation pointer. With the Automatic Radial Centering feature provided on the INS 422 system, this is done automatically when the external momentary button is pushed.
Pushing the remote automatic radial centering button enables circuitry to automatically position the digital CDI indication to provide a one-time radial "TO" the VOR station. The digital indications displayed on the CDI will then return to conventional operation, permitting the radial to be flown in a conventional manner.
