G900X SYSTEM ANNUNCIATIONS
Upon power-up, certain windows remain invalid as G900X equipment begins to initialize. All windows

should be operational within one minute of power-up. If any window continues to remain flagged, the

failed data (refer to Figure A-3 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.
