VOR/MKR DESCRIPTION/OPERATION
GENERAL
The Very High Frequency Omni-Directional Range (VOR)
and Marker (MKR) system includes:
- 2 Identical VOR/MKR receivers (only MKR1 system
is installed on aircraft),
- 1 Dual VOR ANTENNA,
- 1 MKR ANTENNA.
VOR AUTO TUNING
In normal operation each Flight Management and Guidance
Computer (FMGC) automatically tunes its ownside VOR
receiver through its ownside Radio Management Panel
(RMP) via port A.
With failure of one FMGC, the other FMGC can control
the two VOR/MKR receivers, one directly, the other
through its Radio Management Panel (RMP).
When the FMGC fails, the VOR receives a discrete
through the RMP to automatically select port B.
VOR MANUAL TUNING
From each Multipurpose Control and Display Unit (MCDU)
both VORs can be manually tuned through their ownside
FMGC .
VOR BACK UP TUNING
In case of dual FMGC failure, the RMPs enable BACK-UP
tuning.
VOR ANTENNA
The dual VOR antenna receives the signals coming from
the ground stations.
The VOR Antenna operates in the 108 to 117.95 Mhz
range.
VOR USERS
The VOR data is sent to the FMGCs for aircraft position
computation.
MKR CONTROL
The system consists of two identical VOR/MKR receivers
but only MKR one is operative as it is connected to
the MKR antenna.
The MKR system operates at a fixed frequency and does
not need any control.
MKR ANTENNA
The MKR antenna receives MKR signals when the aircraft
flies over the MKR beacons.
The MKR Antenna operates at 75 Mhz.
