R NOTE : Station identification consists of 4 characters max. : label
____ R 263 provides the first two characters (bits 11 to 17 for the R first character and bits 19 and 25 for the second one) and R label 264 gives the last two characters (bits 11 to 17 for the R third character and bits 19 to 25 for the fourth one).

B. Antennas
(Ref. Fig. 009)
(1)
Localizer antenna The localizer antenna is an airborne antenna used to receive LOC signals in the 108-112 MHz range. It is a folded half-loop type driven by capacitive coupling. The antenna has two independent RF connectors used to feed two items of equipment. Connector separation is provided by a hybrid junction in the antenna.
(2)
Glide/slope antenna The glide/slope antenna is an airborne antenna used to receive GLIDE signals in the 329-335 MHz range. It is a folded half-loop type driven by capacitive coupling. The antenna has two independent RF connectors used to feed two items of equipment. Connector separation is provided by a hybrid junction in the antenna.

A. Control
-each ILS receiver is connected to one Radio Management Panel (RMP). The ILS receiver 1 is connected to the RMP1 (the ILS receiver 2 to the RMP2). The ILS receiver 1 receives management bus from the FMGC1 through the RMP1 (the ILS receiver 2 from the FMGC2 through the RMP2)
-in normal operation, the FMGC1(2) tunes the ILS 1(2) receiver either automatically or manually by means of the MCDU1(2). In this case the RMP1(2) operates as a relay which sends the frequency information from the FMGC1(2) to the receiver 1(2).

-by a second port, the ILS receiver 1(2) receives a second management bus (ILS1 FREQ + RWY HDG1) directly from the FMGC2(1). The receiver selects one of the two port functions by a discrete signal (RMP1 NAV DISC) which is received from the FMGC1(2) through the RMP1(2). With fault of one FMGC, the second FMGC can control the two ILS receivers, one directly, the other through its RMP. With fault of the RMP1(2) or two RMPs, the concerned RMP is transparent to data and discrete from FMGC. In manual operation (at any time, or with fault of two FMGCs) the RMP1 can control the ILS receiver 1 after ON NAV mode selection. Same possibility for the RMP2 (ILS receiver 2).
R (Ref. Fig. 010) In this mode the RMP1 can control the ILS2 through the RMP2 after ON NAV mode selection on the RMP2. Same possibility for ILS2 through RMP1. After any frequency selection it is always necessary to select the associated course.
-In LAND mode below 700 ft., the FMGC sends a ground signal on the TUNE TEST INHIBIT discrete to the ILS receiver. In this case, whether the frequency is sent by the FMGC or by the RMP, the ILS receiver does not take into account any frequency change.
B. Reconfiguration Switching In normal utilization, the ILS1 data are shown on the CAPT PFD and the F/O ND ; the ILS2 data on the F/O PFD and the CAPT ND. In addition the DMC 1 supplies data to the CAPT PFD and ND ; the DMC 2 to the F/O PFD and ND. With fault of the DMC 1(2), 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. With fault of the PFD, there is an automatic transfer of the PFD image onto the ND. With fault of the ND, you obtain the transfer of the ND image onto the PFD when you push the PFD/ND XFR pushbutton switch on panel 301VU (500VU). When you set the PFD potentiometer to OFF on panel 301VU (500VU), this causes :
-deactivation of the PFD
-transfer of the PFD image onto the ND.

A. Access to ILS Sub-Menu Functions It is possible to select the maintenance functions of the ILS receiver 1
(2) by pressing the line key adjacent to the SYSTEM REPORT/TEST indication on the CFDS menu, and then selecting the relevant ILS on the NAV menu. After these actions, the ILS 1 (2) provides its own menu page and the sub-menu functions can then be chosen by the operator.
