The G1000 Alert System conveys alerts to the pilot using combinations of the following features:
Alert Window:
The Alert window displays alert text messages. Pressing the ALERTS softkey displays the Alerts
window. Pressing the ALERTS softkey again removes the Alerts window from the display.
Softkey Annunciation:
When the G1000 Alerting System issues an alert, the ALERTS softkey is used as a flashing annunciation
to accompany the alert. During the alert, the ALERTS softkey changes to ADVISORY as shown in
Figure 5-3. Pressing the softkey annunciation acknowledges the presence of the alert and displays the
advisory message in the Alerts Window.
