SYSTEM ANNUNCIATIONS
When an LRU or an LRU function fails, a large red ‘X’ is typically displayed over the instrument experiencing
failed data (Figure 1-21 displays all possible flags and responsible LRUs). The system alerts the pilot when
backup paths are utilized by the LRUs. Upon 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 system should be serviced by a Garmin-authorized repair facility.
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.
