The radio magnetic indicator (RMI) shows bearing data to a VOR or ADF station with reference to the airplane magnetic heading.
The RMI has two bearing pointers. There is a fail flag for bearing pointer 1, and a fail flag for bearing pointer 2. The bearing pointer 1 and flag 1 show bearing and status from the VOR/MB receiver 1 or ADF receiver 1. The bearing pointer 2 and flag 2 show bearing and status from the VOR/MB receiver 2 or ADF receiver 2.
Set the bearing pointer VOR/ADF selectors to VOR to show VOR bearing on bearing pointers 1 and 2.
With the VOR/ADF selectors in the VOR position, the fail flags show for invalid data from 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 th
General
These are the components in the flight compartment that interface with the VOR system:
· Captain’s primary and secondary EFIS displays
· Left and right EFIS control panels
Circuit breakers
The VOR circuit breakers supply 115v ac power for receiver operation. VOR/MB receiver 1 gets power from the ac standby bus, section 1 and VOR/MB receiver 2 gets power from the ac transfer bus 2, se
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 d
Test and Indication
There are two light emitting diodes (LEDs) and a test switch on the front of the VOR/MB receiver. The LEDs show receiver test status when you do a test of the VOR/MB receiver. The red control fail
Operation
The NAV control panel has an active frequency display window and a standby frequency display window. The frequency that shows in the active frequency display window is the frequency that the naviga
Operation
Frequency tune inputs from the NAV control panel go to an ARINC 429 receiver in the VOR/MB receiver, then to the processor. The processor sends the tune inputs to the frequency synthesizer to tune
Instrument Switching Module
The instrument switching module on the P5 overhead panel provides discretes to the display electronics unit (DEU) for display switching when you move the switch to the both on 1 or both on 2 positi
Audio Control Panel Controls
The audio control panels (ACP) permit the crew to listen to VOR station audio or the morse code station identifier.
You use the ACP volume control switches to select the VOR/MB system you
Bearing Pointers
Bearing pointers 1 and 2 show in green around the edge of the compass rose when you set the VOR/ADF switches on the EFIS control panels to the VOR position. There is a pointer head and tail for bot
TO/FROM Pointer and Indicator
The TO/FROM pointer is a small white triangle that shows as part of the selected course pointer. The TO/FROM pointer shows on the centered VOR display only.
The TO/FROM indicator shows at
VOR Frequency
The VOR frequency shows in the upper right next to the NAV data source. The frequency from the NAV control panel goes through the VOR/MB receivers, then to the DEUs for display. The frequency shows
