ILS - Warning Display R Figure 006
R 1EFF : 001-004, 051-060, 1 34-36-00Page 12 1 1 Config-1 May 01/05 1 1 1CES 1 The ND shows the indications given after, when available, in its right top corner (item 8):
-
the side of the displayed ILS receiver,
-
the frequency,
-
the course,
-
the identification. The ND shows the ILS APP message in its center top section (item 7) when the pilot has selected the ILS approach on the MCDU. LATERAL DEVIATION (item 6) a dagger-shaped pointer points to the selected ILS course. Its center part is the lateral deviation bar, which can move on a scale which is perpendicular to the pointer and has 2 dots on each side. The position of the bar on the scale gives the localizer deviation. The extreme dots correspond to plus or minus
0.155 ddm (plus or minus 150 micro A). With LOC fault a red LOC warning message comes into view in the middle of the LOC scale and the LOC deviation bar goes out of view. VERTICAL DEVIATION (item 9) a magenta lozenge gives the glide slope deviation on a vertical scale at the right of the heading dial if the aircraft is within the condition of reception of the ILS glide slope signal. The extreme dots of the vertical scale correspond to plus or minus 0.175 ddm (plus or minus 150 micro A). With G/S fault, a red G/S warning message comes into view at the top of the scale and the index goes out of view.
(c) On ND in ARC and ROSE NAV modes When you push the ILS pushbutton switch in ARC or ROSE NAV mode, the ND shows the symbols given after:
-a magenta dagger-shaped pointer which points to the selected QFU,
-an arrow which indicates the lateral deviation of the aircraft related to the localizer axis.
(2) Audio control The ILS receiver applies its audio output to the audio integrating system. This system controls and directs the output to the headsets and/or the loudspeakers. The Audio Management Unit (AMU) controls the audio level through the Audio Control Panel (ACP). On the ACP, the pilot must push the ILS pushbutton switch and adjust the related potentiometer to the correct audio level. With ILS/DME collocated stations, the DME identification Morse code can be listened in sequence with the ILS audio signal when you push the ILS pushbutton switch on the ACP and the ILS pushbutton switch on the FCU.

The LCD is used as a fault display and as an operator interface
during certain modes. The front panel display also provides user
interfaces for test and troubleshooting.
The front panel contains two momentary pushbutton switches for
interfacing with the LCD pages.
The back is equipped with one ARINC 600 size one connector, which
includes three plugs:
- Top Plug (TP): connection with the automatic test circuits
- Middle Plug (MP): service interconnection
- Bottom Plug (BP): connection with the power supply circuit, and the
LOC and G/S coaxial interconnections.
