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 when a warning, caution, advisory
alert, or G1000 message advisory occurs. System alert messages are provided for awareness of G1000 system
problems or status and may or may not require pilot action. The Alerts Window allows system alerts to be
displayed simultaneously. The FMS Knob is 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 turns the softkey 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 label, and when pressed again opens the Alerts Window to display a
descriptive message of the alert.
Caution indicates the existence of abnormal conditions on the aircraft that may require pilot intervention. A
flashing CAUTION Softkey annunciation and single aural tone (one chime) indicate the presence of a caution.
The flashing CAUTION Softkey annunciation continues to flash until acknowledged by pressing the CAUTION
Softkey.
Warnings are time-critical and require immediate attention. A flashing WARNING Softkey annunciation 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 WARNING Softkey.
The Annunciation Window appears to the right of the Vertical Speed Indicator and displays abbreviated
annunciation text for aircraft alerts. Warnings appear in red, cautions in yellow, advisory alerts in white,
and safe operating annunciations in green. New alerts are displayed at the top of the Annunciation Window,
regardless of priority. Once acknowledged, they are sequenced based on priority.
