G1000 SYSTEM ANNUNCIATIONS

When a new message is issued, the

MSG

Softkey flashes to alert the flight crew of a new message. It continues

to flash until acknowledged by selecting the softkey. Active messages are displayed in white text. Messages that
have become inactive change to gray text. The

MSG

Softkey flashes if the state of a displayed message changes

or a new message is displayed. The inactive messages can be removed from the Message Window by selecting
the flashing

MSG

Softkey.

The G1000 System Messages conveys messages to the flight crew regarding problems with the G1000 system.

Typically, a large red ‘X’ appears in a window when a related LRU fails or detects invalid data.

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.

NOTE:

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.
