ADF are shown as green pointers, here ADF 1.
VOR are white pointers, in this example VOR 2.
Note also that the receiver 1 data is displayed
on the left side of the ND and the receiver 2 data
on the right side.
The associated nav aid data is displayed at
the bottom of the ND in their respective colors
and sides.

In the unlikely event of a double FMGC
failure, the back up tuning mode provides
radio navigation redundancy to the crew.
The back up tuning mode is accessed
via the Radio Management Panels (RMP).

DME 1 DME 2
For nav aid tuning, RMP 1 STBY NAV keys are
associated with VOR/DME 1 and ADF 1 while RMP 2
keys are associated with VOR/DME 2 and ADF 2.

The ILS keys are slightly different. The
ILS frequency tuned on either RMP is sent
to both ILSs.

To access the back up tuning mode,
the NAV key has to be pressed.
NAVIGATION MENU
Radio Nav. presentation 16/22
When the back up tuning mode is selected, i.e. NAV key
illuminated, the control of the associated receivers is
transferred to the RMP and the nav aid tuning capability of
both FMGC is lost.
This is indicated on the MCDU by a change to the RAD
NAV page which shows only the titles now.
To return the control to the FMGC, the NAV key has to
be pressed again.

In back up tuning mode, the selection of
one of the STBY NAV keys enables the
crew to tune the associated nav aid.
We will see how to operate them in the
abnormal operation module.
We will now study the Digital Distance
and Radio Magnetic Indicator (DDRMI).
NAVIGATION MENU
Radio Nav. presentation 18/22
The DDRMI is fitted on the main
panel.
The DDRMI displays ADF, VOR
and DME raw data and combines a
traditional RMI and bearing pointer
presentation.
NAVIGATION MENU
Radio Nav. presentation 19/22
Two bearing pointers are provided, each with a
different distinguishable shape.
Each can display either VOR or ADF information.
NAVIGATION MENU
Radio Nav. presentation 20/22
Each pointer has an associated control knob.
• The left knob selects either VOR 1 or ADF 1
• The right knob selects VOR 2 or ADF 2.
Here, VOR 1 and VOR 2 are selected.

The compass card displays the bearing
scale that is supplied from ADIRU 1.
NAVIGATION MENU Radio Nav. presentation 22/22
The counters indicate the
DME distance.
However, the window will
display only dashes if an
ADF is selected.
Here, ADF 2 is selected.

The GPWS monitors the aircraft
flight path and generates visual and
audio warnings/alerts when the aircraft
is in one of the defined hazardous
situations. These warnings will be overridden
by stall or windshear warnings.
The A320 family is equipped with a Ground
Proximity Warning System (GPWS).
Its purpose is to enhance safety by alerting
the crew to potentially hazardous situations
involving terrain collision or incorrect landing
configuration.

Failures of these units will be studied in
the abnormal operation modules.
