Annunciation System
Refer to the Cirrus Perspective Pilot's Guide for a detailed
description of the annunciator system and all warnings,
cautions and advisories.
Crew Alerting System
AFCS alerts are displayed in the Crew Alerting System (CAS) window
located to the right of the altimeter and VSI. AFCS annunciations are
grouped by criticality and sorted by order of appearance with the most
recent message on top. The color of the message text is based on its
urgency and required action:
• Warning (red) – Immediate crew awareness and action required.
• Caution (yellow) – Immediate crew awareness and future
corrective action required.
• Advisory (white) – Crew awareness required and subsequent
action may be required.
In combination with the CAS Window, the system issues an audio alert
when specific system conditions are meet and an expanded
description of the condition is displayed in the Alerts Window located
in the lower RH corner of the PFD.
For specific pilot actions in response to AFCS alerts, refer to
Section 3A - Abnormal Procedures.
AFCS Status Box and Mode Annunciation
Flight Director mode annunciations are displayed on the PFD when
the Flight Director is active. Flight director selection and Autopilot
statuses are shown in the center of the AFCS Status Box. Lateral
Flight Director modes are displayed on the left and vertical on the
right. Armed modes are displayed in white and active in green.
AFCS status annunciations are displayed on the PFD above the
Airspeed and Attitude indicators. Only one annunciation may occur at
a time. Messages are prioritized by criticality.
