2.4 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 2-36) 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 selecting the
ALERTS
Softkey. If the window is already open when a new
message is generated, selecting the
ALERTS
Softkey to acknowledge the message causes it to turn gray.
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.

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

a descriptive message of the alert.
Warnings are time-critical and require immediate pilot attention. A flashing

and aural tone (single chime every two seconds) indicate the presence of a warning. The aural tone and flashing
WARNING
Softkey annunciation continue until acknowledged (by pressing the
