3.2 Crew Alerting Systemystem (CAS) NOTE: 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. NOTE: If there is a mismatch between databases or software on the PFDs, CAS is inoperative.
The Crew Alerting System (CAS) Display is located in the lower left corner of the EICAS Display (on the MFD) under normal display conditions. Up to 14 messages can be displayed; when more than 14 messages accumulate, the scrolling CAS softkeys become available.
When CAS messages are present while in reversionary mode, the CAS Window appears on the display along with the flight instruments and EIS. The window size increases to fit up to 14 CAS messages; if more than 14 messages are generated, the messages can be scrolled through using the CAS softkeys (two left-most softkeys).

CAS Messagesessages and Prioritizationrioritization NOTE: Information on CAS messages in this pilot’s guide is always superseded by the AFM.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:
• Warning (red) – Immediate crew awareness and action required; Master Warning triggered
• Caution (yellow) – Immediate crew awareness and possible future corrective action required; Master Caution triggered
• Advisory (white) – Crew awareness required and subsequent action may be required

Any CAS messages that come up when the system is first powered on are considered already acknowledged. They do not flash or trigger the Master Warning or Master Caution. CAS messages listed in Table 3-4 are shown in the acknowledged state (text corresponding to criticality on a black background).
Since red and yellow CAS messages indicate the immediate or future need for corrective action, two momentary buttons are located above each PFD for CAS message acknowledgment: Master Warning and Master Caution.
When a new red CAS warning message appears, it flashes in conjunction with the Master Warning Indicator. Pressing a Master Warning Indicator acknowledges all flashing red messages, extinguishes the master warning lights, and stops the message flashing. Messages are displayed until the issue is corrected and a Master Warning Indicator has been pressed.
When a new yellow caution message appears on the CAS display, it flashes and triggers the Master Caution Indicator to come on, but not to flash. Pressing a Master Caution Indicator acknowledges all flashing yellow messages, extinguishes the master caution lights, and stops the message flashing. Messages are displayed until the issue is corrected.

A CAS message does not appear more than once at a given time (unless the CAS is being tested). If signals are received that justify multiple priorities for a certain message, the message is displayed for the higher priority condition. When graduating to a higher priority, the message flashes and requires new acknowledgment. When degrading to a lower priority condition, the message moves to the top of the appropriate grouping, but does not require new acknowledgment.
Red warning messages cannot be scrolled through and remain at the top of the CAS display. The scroll bar changes color to yellow if more caution messages exist than can be displayed at once or if caution messages have been scrolled off the display. The scroll bar remains in the selected position for 45 seconds or until a new caution message is generated, at which point the scroll bar returns to the top of the display.
