G1000 SYSTEM ANNUNCIATIONS
NOTE: For a detailed description of all annunciations and alerts, refer to Appendix A. Refer to the Pilot’s
Operating Handbook (POH) for additional information regarding pilot responses to these annunciations.
When an LRU or an LRU function fails, a large red “X” is typically displayed on windows associated with
the failed data (Figure 1-13 displays all possible flags and responsible LRUs). Upon G1000 power-up, certain
windows remain invalid as equipment begins to initialize. All windows should be operational within one
minute of power-up. If any window remains flagged, the G1000 system should be serviced by a Garmin-
authorized repair facility.

SOFTKEY FUNCTION
The softkeys are located along the bottoms of the displays. The softkeys shown depend on the softkey level
or page being displayed. The bezel keys below the softkeys can be used to select the appropriate softkey. When
a softkey is selected, its color changes to black text on gray background and remains this way until it is turned
off, at which time it reverts to white text on black background.
