Aural alerts associated with abnormal conditions and advisories are managed through the audio 

panels.  Refer to the Audio Panel and CNS Section for more information.

When Crew Alerting System (CAS) messages are generated, the CAS Window opens to the right of the Altimeter 

(on the PFDs).  Up to 14 messages can be displayed; when more than 14 messages accumulate, the CAS Softkey 
becomes available.  Pressing the CAS Softkey displays softkeys for scrolling up and down through the messages 
in the CAS Window.

In Reversionary Mode, the CAS Softkey takes the place of the INSET Softkey.

Information on CAS messages in this pilot’s guide is always superseded by the AFM.

CAS messages are grouped by criticality (warning, caution, 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, and the MSG 
Softkey label changes to display the appropriate annunciation when a CAS message is generated.

• Warning (red) – Immediate crew awareness and immediate crew action required; accompanied by an aural

tone (triple chime every 3 seconds) and flashing ‘WARNING’ softkey annunciation

• Caution (yellow) – Immediate crew awareness and subsequent corrective action required; accompanied by

an aural tone (single chime every 5 seconds) and flashing ‘CAUTION’ softkey annunciation

• Advisory (white) – Crew awareness required and subsequent action may be required; accompanied by a

flashing ‘ADVISORY’ softkey.
