Messages and Prioritization
NOTE: Red warning messages cannot be scrolled
through and remain at the top of the CAS display.
The scroll bar changes to yellow if more than ten
caution messages exist to be scrolled through.
CAS messages are grouped by criticality (warning,
caution) and sorted by order of appearance (most recent
messages on top).
• 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
When a new red CAS warning message appears, it
flashes (inversely red on white) in conjunction with the
Master Warning Indicator. Pressing the Master Warning
Indicator acknowledges all flashing red messages,
extinguishing the master warning lights, and stops
warning message flashing. Once acknowledged, CAS
warning messages are shown in red text and are displayed
until the issue is corrected.
