UNABLE FMS-FMS
SYNC
In a dual/triple-FMS installation, operator’s or
automatic attempt to synchronize FMSs
failed because:
1. An inter-FMS communication failure has
occurred.
2. The Operational Software programs are
not the same in all FMSs.
3. The active navigation database is not the
same in all FMSs.
Any automatically synchronized item listed in
Section 3 of the Operator’s Manual,
dual/triple-FMS Operations, must be now
performed independently on each FMS.
1. Refer to MESSAGE RECALL and/or
MAINT MESSAGE page(s) for more
details. Advise maintenance.
2. Verify Op Program on IDENT 1/1 page
and advise maintenance if different.
3. Verify active navigation database on
IDENT 1/2 page, select appropriate
database if possible, otherwise advise
maintenance.
