General
The VOR system has two VOR/marker beacon (VOR/MB)
receivers. The receivers have VOR and marker beacon
functions. This section covers only the VOR operation of the
VOR/MB receivers.
Description
The navigation (NAV) control panels give manual tune inputs to
the VOR/MB receivers. There are two NAV control panels, one
for the captain and one for the first officer.
RF signals from the VOR/LOC antenna go through power
dividers, then to the VOR/MB receivers. The VOR/MB receivers
use the RF signals to calculate station bearing and decode the
morse code station identifier signal and station audio.
The receivers send VOR bearing to the remote magnetic
indicator (RMI). You can select the RMI bearing pointers to
show VOR or ADF station bearing with the RMI bearing pointer
selectors.
The receivers send VOR bearing data to the display electronic
units (DEU) for display. The NAV select switch lets the crew
select VOR/MB receiver 1 or VOR/MB receiver 2 as the source
for the captain and first officer displays.
The receivers send station audio and morse code station
identifier signals to the remote electronic unit (REU).
The receiver sends VOR bearing data to the FCCs for the DFCS
VOR/LOC mode of operation. The bearing data also goes to the
FMCS as a radio navigation aid for present position
calculations.
