The VHF Omni Range (VOR) system gives the bearing of
a ground VOR Station with respect to the magnetic North
and the aircraft angular deviation related to a
preselected course.
The Global Positioning System (GPS) is based on the
measurement of the transmission time of signals
broadcast by satellites.
This part of the Navigation includes:
- 2 DME,
- 2 ATC,
- 1 ADF (the second is optional),
- 2 VOR,
- 2 GPS.
NOTE 1: The VOR or DME frequency control is achieved
either automatically or manually (through the
MCDU) by the FMGCs or manually though the RMPs.
NOTE 2: Although the Marker Beacon belongs to the
Landing Aids System, it is physically
integrated into the VOR receiver.

RADIO NAVIGATION CONTROL PRESENTATION
AUTOMATIC TUNING
The Automatic Tuning permits the control of VOR / DME,
ILS and ADF by the Flight Management and Guidance
System.
In this case the RMP is transparent to its associated
FMGC.
In normal operation FMGC1 tunes receivers 1, FMGC2
tunes receivers 2.
In case of failure of FMGC 1 or 2, the remaining FMGC
controls all receivers.
MANUAL TUNING
The manual tuning permits the pilot to select, through
the Multipurpose Control Display Unit, a specific
frequency for display on the EFIS.
NOTE: To return to the autotuning mode, the manual
tuning has to be cleared.
BACK-UP TUNING
Radio Management Panels 1 and 2 located on the pedestal
provide back-up for Radio Navigation tuning.
We are in the case of both FMGCs inoperative or
emergency electrical supply.
The ILS course and frequency are the only Radio
Navigation data exchanged.
The selected values on RMP 1 and RMP 2 are identical
for ILS 1 and ILS 2.

SELF EXAMINATION
Can VOR 2 frequency be changed through RMP 1?
A - Yes.
B - No.
In back-up mode, an ILS can be tuned through:
A - RMP 1 or 2.
B - RMP 1 only.
C - The onside RMP only.

MULTIPURPOSE CONTROL DISPLAY UNIT (MCDU)
The Multipurpose Control and Display Unit (MCDU) allows
the crew:
- To display the Radio Navigation frequencies
(automatically or manually tuned) on a specific
page called RAD/NAV.
- To align the Inertial Reference systems from
a specific page called INIT via the FMGC.
- To initiate tests for all navigation
systems and for troubleshooting via the
CFDIU.
