FCOM 19 AUG 10
GENERAL
Applicable to:
The FMGS has three modes of operation:
‐ Dual mode (the normal mode)
‐ Independent mode. Each FMGC being controlled by its associated MCDU
‐ Single mode (using one FMGC only).

The FMGS has four modes of operation:
‐ Dual mode (the normal mode)
‐ Independent mode. Each FMGC being controlled by its associated MCDU
‐ Single mode (using one FMGC only)
‐ Back–up navigation mode.
DUAL MODE
Applicable to: ALL
This is the normal mode. The two FMGCs are synchronized: each performs its own computations
and exchanges data with the other through a crosstalk bus.
One FMGC is the master, the other the slave, so that some data in the slave FMGC comes from the
master.
All data inserted into any MCDU is transferred to both FMGCs and to all peripherals.

MASTER FMGC LOGIC
If one autopilot (AP) ‐ is engaged, the related FMGC is master:
• It uses the onside FD for guidance
• It controls the A/THR
• It controls the FMA 1 and 2.
‐ If two APs are engaged, FMGC1 is master.
‐ If no AP is engaged, and
• The FD1 pb is on, then FMGC1 is master
• The FD1 pb is off, and FD2 pb on then FMGC2 is master.
‐ If no AP/FD is engaged, A/THR is controlled by FMGC1.

INDEPENDENT MODE
Applicable to:
The system automatically selects this degraded mode under specific abnormal conditions (e.g.
different database validity on both FMGCs).
Both FMGCs work independently and are linked only to peripherals on their own sides of the flight
deck (“onside” peripherals).
When this occurs, the “INDEPENDENT OPERATION” message is displayed on both MCDU
scratchpads.
