12.3 G1000 SYSTEM ANNUNCIATIONS
When an LRU or an LRU function fails, a large red
‘X’ is typically displayed on windows associated with the
failed data. The following section describes various sys-
tem annunciations. Refer to the Aircraft Flight Manual for
additional information regarding pilot responses to these
annunciations.
NOTE: Upon power-up of the G1000 system,
certain windows remain invalid as G1000 equip-
ment begins to initialize. All windows should
be operational within one minute of power-up.
Should any window continue to remain flagged,
the G1000 system should be serviced by a
Garmin-authorized repair facility.
