- ILS frequencies and courses, if any.
After a flight plan change, there is a comparison on
the active leg and, every second, on the active
performance mode and active guidance mode. If it is
different, the slave computer will synchronize itself
to the master one by copying the master values.
Also, aircraft position, Gross Weight and target speeds
from master and slave computers are compared every
second.
If the difference is greater than 5 Nm, 2 tons or 2
Kts respectively, an appropriate message is displayed
on the MCDUs:
- "FMS1/FMS2 POS DIFF"
- "FMS1/FMS2 GW DIFF"
- "FMS1/FMS2 SPD TGT DIFF"
Pilot action is then required.
INDEPENDENT MODE
In INDEPENDENT mode, there is no interaction from one
system to the other one. The FMGCs only send their
status information to each other (e.g., in this case,
the INDEPENDENT mode).
SINGLE MODE
In SINGLE mode, both MCDUs are driven by the same FM
part, but they can still display different pages.
Messages linked to the navigation process are displayed
on both MCDUs.

MCDU
As already presented in the FM OPERATING MODES topic,
the MCDUs work differently.
In NORMAL mode, the MCDUs can be used simultaneously
on different pages. Any modification or entry on one
MCDU is transmitted to the other MCDU via the FMGC
crosstalk.
In INDEPENDENT mode, both MCDUs operate separately.
Although the crosstalk is present, an entry on one
MCDU is not applied to the other one.
In SINGLE mode, both MCDUs basically work as in normal
mode, but with the valid FMGC only.
DISPLAYS
Flight Management information is displayed on
Navigation Displays (NDs) and on Primary Flight
Displays (PFDs).
For FM information, in NORMAL or INDEPENDENT modes,
FMGC1 supplies PFD1 and ND1, FMGC2 supplies PFD2 and
ND2.
In SINGLE mode, the remaining FMGC supplies all the
displays.
RADIO NAVIGATION
The schematic shows the architecture of the radio
navigation receivers controlled by the FMGCs in NORMAL
or INDEPENDENT modes.
For the selection of radio navigation frequencies and
courses, in normal or independent modes, each FMGC
controls its own side receivers through a Radio
Management Panel (RMP).
Only the actual frequencies and courses from the
receivers are displayed on the PFDs and the NDs.
In case of an FMGC failure, the valid FMGC controls
its own side receivers as usual, through an RMP, but
also the other side receivers, directly without going
through an RMP.
If both FMGCs fail, the crew must use the RMPs to
select the frequencies and courses.

How do the FMGCs operate in the INDEPENDENT mode?
A - Side 1 and side 2 Flight Guidance
functions are independent.
B - Side 1 and side 2 Flight Management
functions are independent.
C - One side is inoperative and the
remaining FMGC controls both sides.
How are the PFDs and NDs supplied with Flight
Management information when both FMGCs are
operative?
A - The master FMGC supplies both PFDs and
NDs.
B - The slave FMGC supplies both PFDs and
NDs.
C - Each FMGC supplies its related PFD and
ND.

FLIGHT PLAN
The flight plan is defined by various elements which
indicate the routes the aircraft must follow with the
limitations along these routes.
The elements are mainly taken from the data bases or
