-
In case of the RMP 1(2) or two RMPs fault, the concerned RMP is transparent to data and discrete from the FMGC.
-
In emergency configuration (in case of two FMGCs fault) the RMP 1 can control the VOR/MKR receiver 1 after ON NAV mode selection. Same possibility for the RMP 2 (VOR/MKR receiver 2).
(Ref. Fig. 011)
(2) Marker system The marker receiver is contained in the VOR/MKR receiver. In normal operation, the VOR/MKR receiver receives a signal when the aircraft overflies the corresponding marker.
B. Reconfiguration Switching In normal utilization, both VOR 1 and 2 data are shown on the CAPT (F/O) ND through their respective Display Management Computer (DMC 1(2)). The marker data are shown on the CAPT (F/O) PFD through the DMC 1(2). In case of the DMC 1(2) fault, it is possible to switch over to the DMC 3 with the EIS DMC selector switch. This selector switch is located on panel 8VU on the center pedestal. In this case the DMC 3 totally replaces the DMC 1(2) through the stage of the output switching relay of the failed DMC. In case of PFD fault, there is an automatic transfer of the PFD image into the ND. In case of ND fault:
-you obtain the transfer of the ND image onto the PFD when you push the
PFD/ND XFR pushbutton switch on panel 301VU (501VU). When you set the PFD potentiometer to OFF on panel 301VU (501VU), this causes :
-deactivation of the PFD
-transfer of the PFD image onto the ND.

A. Access to the VOR/MKR Sub-menu Functions It is possible to select the maintenance functions of the VOR/MKR receiver 1 (2) on the MCDU1 (2) by pressing the line key adjacent to the SYSTEM REPORT/TEST indication on the CFDS menu, and then selecting the relevant VOR on the NAV menu. After these actions, the VOR 1 (2) provides its own menu page and the sub-menu functions can then be chosen by the operator.
B. Activation of the Test Function The test function can be activated in ground conditions only. The VOR/MARKER test can be activated from any of the following sources:
-
the tuning frequency word's SSM set to "TEST"
-
the front panel pushbutton
-via the ARINC 429 CFDIU Data Bus (on the ground only)
-the CFDS interactive menu.
(1)
The SSM must be continuously updated and must reflect the current states of the BITE. If any failures are present the SMM must be set to "FAIL". If no failures are present, then the SMM must be set to "TEST".

A. CFDIU Interface
(1) BITE description The BITE facilitates maintenance on in-service aircraft. It detects and identifies a failure related to the VOR system. The BITE of the VOR receiver is connected to the CFDIU (Ref. 31-32-00). The unit tested is the VOR receiver. The BITE:
