VOR/MB Output

The VOR/MB receivers each have two output buses. One output bus from each receiver goes to the on-side FCC. VOR/MB receiver 1 supplies VOR data and status to FCC A. VOR/MB receiver 2 supplies VOR data and status to FCC B. The FCCs use the data for the autopilot VOR mode of operation. The other output bus of each receiver sends VOR data and status to these components:

· FDAU for data to record by the digital flight data recorder

· RMI for bearing pointer displays

· FMC for position update calculations

· FMC 1 and FMC 2 for position update calculations

· DEUs for VOR displays.
