SECTION 12 – ANNUNCIATIONS
& ALERTS
12.1 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 12-2. Pressing
the WARNING Softkey acknowledges the presence
of the warning alert and stops the aural tone, if
applicable.
• CAUTION: This level of alert indicates the
existence 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
in the Annunciation Window is YELLOW. A caution
alert is also accompanied by a flashing CAUTION
Softkey annunciation, as shown in Figure 12-3.
Pressing the CAUTION Softkey acknowledges the
presence of the caution alert.
• MESSAGE ADVISORY: This level of alert provides
general information to the pilot. A message
advisory alert does not issue annunciations in the
Annunciation Window. Instead, message advisory
alerts only issue a flashing ADVISORY Softkey
annunciation, as shown in Figure 12-4. Pressing
the ADVISORY Softkey acknowledges the presence
of the message advisory alert and displays the alert
text message in the Alerts Window.
