Proline IV Navigation Receiver including fully digital VOR/LOC, glideslope, and marker beacon receivers
Provides serial-digital I/O interface and features digital signal processing for improved performance
Accepts conventional 2-out-of-5 tuning and provides conventional sine/cosine outputs
Controlled by either an ARINC 429 signal from a controller or by CTL-32
May be installed as a direct replacement for Proline I VIR-30A
Models and modification available for units to meet ICAO Annex 10 which reduces interference by high-power FM broadcast radio stations (see table below)
