12.6 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 Aircraft Flight Manual
takes precedence over any conflicting guidance found in this section.
