ENGINE INDICATION & CREW ALERTING SYSTEM
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NOTE: Information on CAS messages in this pilot’s guide is always superseded by the RFM.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.
•Warning (red) – Immediate crew awareness and immediate crew action required; accompanied by one or
more aural tones; and a steady ‘WARNING’’ PBA light is illuminated above the PFD.
•Caution (yellow) – Immediate crew awareness and subsequent corrective action required; accompanied by a
steady ‘CAUTION’ 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 three 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, at which point the message is removed.
NOTE: See the Rotorcraft Flight Manual (RFM) for recommended pilot actions.
