APPENDIX A
G950 SYSTEM ANNUNCIATIONS
NOTE:
Upon power-up, certain windows remain invalid as G950 equipment begins to initialize. All windows
should be operational within one minute of power-up. If any window continues to remain flagged, the
G950 System should be serviced by a Garmin-authorized repair facility.
When an LRU or an LRU function fails, a large red ‘X’ is typically displayed on windows associated with the
failed data (refer to Figure A-4 for all possible flags and the responsible LRUs). Refer to the Pilot’s Operating
Handbook (POH) for additional information regarding pilot responses to these annunciations.
