CAS MESSAGE PRIORITIZATION
NOTE: Information on CAS messages in this pilot’s guide is always superseded
by the RFM. Refer to the RFM for recommended pilot actions.
CAS messages are grouped by criticality (warning, caution, advisory, safe operating
advisory) and sorted by order of appearance (most recent messages on top). The
color of the message is based on its urgency and on required action. Refer to the
Annunciations and Alerts section for a detailed listing of CAS alerts and alerting
behavior.
• Warning (red) – Immediate crew awareness and immediate crew action
required; accompanied by one or more aural tones; and a and a steady
“WARN” PBA light is illuminated above the PFD.
• Caution (yellow) – Immediate crew awareness and subsequent corrective
action required; accompanied by a and a steady “CAUT” PBA light is
illuminated above the PFD.
• Advisory (white) – Crew awareness required and subsequent action may be
required.
• Safe Operating Advisory (green) – Crew awareness required.
A CAS message does not appear more than once at a given time. Warning and
caution CAS messages flash when they are generated, and continue to flash until
acknowledged, or until the triggered condition is inactive for more than 3 seconds.
Advisory CAS messages are displayed steady until the triggered condition is inactive
for more than 3 seconds.
After the acknowledgment, a message remains displayed at the top of its respective
priority group in the CAS Window until either a newer message of the same priority
appears or the condition(s) that caused the alert to display no longer exist.
