2.3 PFD ANNUNCIATIONS AND ALERTING FUNCTIONS

The following annunciations and alerting functions are displayed on the PFD. Refer to Appendix A for more
information on alerts and annunciations.

SYSTEM ALERTING

Messages appear in the Alerts Window (in the lower right corner of the PFD; Figure 2-37) when a warning,
caution, advisory alert, or G900X message advisory occurs. System alert messages are provided for aware of
G900X system problems or status and may not require pilot action. The Alerts Window allows system alerts
to be displayed simultaneously. The FMS Knob can be used to scroll through the alert messages. The Alerts
Window is enabled/disabled by pressing the ALERTS Softkey. If the window is already open when a new
message is generated, pressing the ALERTS Softkey to acknowledge the message causes it to turn gray.
The ALERTS Softkey label changes to display the appropriate annunciation when an alert is issued. The
annunciation flashes and the appropriate aural alert sounds until acknowledged by pressing the softkey. The
softkey then reverts to the ALERTS Softkey label, and when pressed again opens the Alerts Window to display
a descriptive message of the alert.
The Annunciation Window appears to the right of the Vertical Speed Indicator and displays abbreviated
annunciation text for aircraft alerts. Text color is based on alert level: warnings appear in red, cautions in
yellow, advisory alerts in white. New alerts, regardless of priority, are displayed at the top of the Annunciation
Window, separated by a white line from acknowledged alerts. Once acknowledged, they are sequenced based
on priority.
