FMS DEGRADED OPERATION
24 FMGC RESETS or FAILURES
PILOT ACTION
On ground:
− CHECK Software/Databases references on each MCDU.
If difference exists, a CROSSLOAD must be performed. Refer to
operator or maintenance procedure.
Note
:
Crossload function is operative in the preflight or done phase only.
In flight :
− Do not switch the NAV data bases.
− Make the same entries on both MCDUs to have similar F-PLN data
and computations in both FMGC.
− If significant differences exist in the two FMGCs, identify the most
accurate and use the associated AP.
Caution
Airbus does not recommend pulling one FMGC circuit breaker to
force the system to operate in SINGLE mode.
