12.7 G1000 SYSTEM MESSAGE
ADVISORIES
This section describes various G1000 system message
advisories. Certain messages are issued due to an LRU
or an LRU function failure. Such messages are normally
accompanied by a corresponding red ‘X’ annunciation
as shown previously in the G1000 System Annunciation
section.
NOTE: This section provides information
regarding G1000 message advisories that may
be displayed by the system. Knowledge of the
aircraft, systems, flight conditions, and other
existing operational priorities must be considered
when responding to a message. Always use
sound pilot judgment. The Columbia 350/400
Airplane Flight Manual (AFM) takes precedence
over any conflicting guidance found in this
section.
