BRG/DIST (4L)
As soon as a navaid name is entered in the
“TO” field (4R), the bearing and distance to this
navaid is displayed and updated in real time.
OPT (1 Center)
This value shows the optimal cruise flight
level computed by the FMGC, depending on the
gross weight and the cost index.
REC MAX (1R)
This is the maximum flight level, displayed in
magenta.
VDEV (2R)
This field is visible during the descent and
approach phases only. It shows the vertical
deviation between the current aircraft position
and the computed flight plan. This information
is also shown on the PFD altitude tape (refer to
the EFIS section for more information).
TO (4R)
This field lets the pilot enter a navaid name.
DIR DIST TO DEST (5R)
This information is visible during the descent
and approach phases only, if you are not in
NAV mode. It shows the direct distance to the
destination approach. It is very useful if the
ATC makes you leave your flight plan and
guides you with heading, in which case you use
the HDG mode.
RAD NAV PAGE
This page is dedicated to the management of
the radio equipment. Remember that any
information written with small characters is
generated by the FMGC, and big characters
correspond to information entered by the
crew.
VOR1/FREQ (1L) and FREQ/VOR2 (1R)
These two fields are dedicated to VOR1 and
VOR2. They display the current VOR names
and frequencies. If you see the identifier and
the frequency both written is small
characters, it means the FMGC has autotuned
this VOR.
The crew can enter a VOR identifier or
frequency in these fields.
If a name is entered, the VOR frequency is
fetched in the database, displayed here, and
set on the VOR receiver. In this case, the
identifier is written in big characters, and the
frequency is in small characters.
If a frequency is entered, the FMGC will fetch
the closest VOR that corresponds to this
FMGC

frequency. The found identifier is then written
is small characters (set by the FMGC) and the
frequency, entered by the crew, is in big
characters.
As soon as an identifier or a frequency has
been entered, the VOR can not be autotuned by
the FMGC until it is released. To do so, press
the CLR key on the MCDU and press 1L or 1R
to release the VOR1 or VOR2. As soon as the
VOR is released, the FMGC will take back
control and use it for autotune.
CRS (2L and 2R)
These fields let you enter the course for VOR1
and VOR2.
ILS/FREQ (3L)
Just like for VOR1 and VOR2, this field shows
the ILS identifier and frequency. You can set
the ILS identifier or frequency like for the
VORs. If the ILS is released, the FMGC will
automatically set the arrival runway ILS when
the approach phase becomes active.
> Because of a limitation in Flight Simulator,
the VOR1 and the ILS are linked and share the
same frequency. Consequently, if you set the
VOR1, the ILS setting is lost, and conversely.
This is why you should make sure VOR1 is
released if you want to have the ILS autotuned
on approach.
CRS (4R)
This field lets you set the ILS course. If the ILS
is autotuned on approach, the ILS course is
automatically set by the FMGC.
ADF1/FREQ (5R)
This field lets you set the ADF in the same way
as the VORs.
ADF BFO (6R)
This activates or stops the frequency
oscillator. This feature is not used by Flight
Simulator.
> The RAD NAV page is the standard way to
set radio equipment manually. You can also
use the left and right Radio Management
Panels (RMP) located on the pedestal to do
this. In this case, the RAD NAV page becomes
inactive as soon as you press the NAV page on
any RMP and it appears like this:
Refer to the Systems section for more
information about the RMP usage.
PAGE SEQUENCING
Now that you know the FMGC and all the
MCDU pages, you may still be lost as to their
use… There are so many pages and you may
not know in which order you should use them.
So here is some further advice:
1 - Initialization
If the menu page appears, press FMGC (1L) to
bring the INIT A page. Otherwise, press the
INIT button.
Enter the FROM/TO airports. If a route exists
and you select it, it brings up the flight plan
page with a temporary flight plan. Validate it
and come back to the INIT A page.
Align the IRS if they are not already aligned.
