When a new alert is issued, the ALERT Softkey flashes to alert the pilot of a new message.  It continues to flash 

until acknowledged by pressing the softkey.  Active alerts are displayed in white text.  Alerts that have become 
inactive change to gray text.  The ALERT Softkey flashes if the state of a displayed alert changes or a new alert is 
displayed.  The inactive alerts can be removed from the Alert Window by pressing the flashing ALERT Softkey.

The G1000 System Messages convey messages to the pilot regarding problems with the G1000 system.  When 

an LRU or an LRU function fails, a large red ‘X’ is typically displayed on windows associated with the failed data.  
The following section describes various system annunciations.  Refer to the POH for additional information 
regarding pilot responses to these annunciations.

Upon power-up of the G1000 system, certain windows remain invalid as G1000 equipment begins to 

initialize.  All windows should be operational within one minute of power-up.  Should any window continue 
to remain flagged, the G1000 system should be serviced by a Garmin-authorized repair facility.
