ANNUNCIATIONS & ALERTS
9.2 ALERT LEVEL DEFINITIONS
The G1000 Alerting System, as installed in Cessna Nav
III aircraft, uses three
alert levels.
• WARNING: This level of alert requires immediate
pilot attention. A warning alert is annunciated in
the Annunciation Window and is accompanied
by a continuous aural tone. Text appearing in the
Annunciation Window is RED. A warning alert is
also accompanied by a flashing WARNING softkey
annunciation, as shown in Figure 9-2. Pressing the
WARNING softkey acknowledges the presence of
the warning alert and stops the aural tone, if appli-
cable.
• CAUTION: This level of alert indicates the exis-
tence of abnormal conditions on the aircraft that
may require pilot intervention. A caution alert is
annunciated in the Annunciation Window and is
accompanied by a single aural tone. Text appearing

alert is also accompanied by a flashing
CAUTION
softkey annunciation, as shown in Figure 9-3.
Pressing the CAUTION softkey acknowledges the
presence of the caution alert.

general information to the pilot. A message advisory
alert does not issue annunciations in the Annuncia-
tion Window. Instead, message advisory alerts only
issue a flashing ADVISORY softkey annunciation,
as shown in Figure 9-4. Pressing the ADVISORY
softkey acknowledges the presence of the message
advisory alert and displays the alert text message in

ciations only appear in the Annunciation Window.
