CREW ALERTING SYSTEM MESSAGES (CAS)
CAS messages are displayed on the right side of the top half of the left MFD. All red messages are displayed at the top, in
order of occurrence (last message at top). Amber, cyan, and then white messages are displayed below the red messages, in
that order.
EICAS MESSAGES
The Crew Alerting System (CAS) provides visual and aural alerts during a malfunction. The CAS prioritizes messages by
order of importance and order of occurrence.
The order of importance is accomplished by the use of color and aural alerts. The four levels of CAS message importance
are: Warning, Caution, Advisory, and Status.
For order of occurrence, the most recent message is displayed at the top of its associated list.
WARNING (W) MESSAGES
The most urgent messages are warnings and red in color. Red warning messages are presented on the top of the CAS page
and remain in view until the problem is resolved.
Warning messages require immediate action and are always accompanied by:
- Triple chime
- Flashing master warning lights
Warning messages, in addition to the above indications, can also generate:
- Voice message
Pressing either master warning switch:
- Silences the aural alerts (except for a non-mutable gear warning)
- Stops the flashing of the master warning lights
CAUTION (C) MESSAGES
Caution messages are second in order of importance. Amber caution messages appear directly below any warning messages
that may be displayed.
Caution messages require prompt action and are always accompanied by:
- Single chime
- Flashing master caution lights
Pressing either master caution switch:
- Stops the flashing of the master caution lights
