Operation

The marker beacon antenna receives the marker beacon signals. The signals go to the VOR/MB receiver 1. The VOR/MB receiver 1 supplies this data:

· Marker beacon audio to the remote electronics unit (REU)

· Marker beacon data to the common display system (CDS) display electronics unit (DEU)

· Marker beacon data to the flight data acquisition unit (FDAU).

The displays show marker beacon data.
