failed PFD) are flagged as invalid.
G1000 SYSTEM ANNUNCIATIONS
When an LRU or an LRU function fails, a large red ‘X’ is typically displayed over the instrument experiencing
failed data (Figure 1-8 displays all possible flags and responsible LRUs). For a detailed description of all
annunciations and alerts, refer to Appendix A. Refer to the Aircraft Flight Manual (AFM) for additional
information regarding pilot responses to these annunciations.
Upon G1000 power-up, certain instruments remain invalid as equipment begins to initialize. All instruments
should be operational within one minute of power-up. If any instrument remains flagged, the G1000 should
be serviced by a Garmin-authorized repair facility.
