CAS MESSAGES AND PRIORITIZATION
NOTE:
Refer to the Pilot’s Operating Handbook (POH) for corrective pilot actions.
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 and caution) 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 action required; accompanied by an aural tone (triple chime
every 3 seconds) and flashing ‘WARNING’ softkey annunciation
•
Caution
(yellow) – Immediate crew awareness and possible future corrective action required; accompanied
by an aural tone (single chime every 5 seconds) and flashing ‘CAUTION’ softkey annunciation
The softkey annunciation flashes and the corresponding aural alert sounds until acknowledged by depressing
the softkey.
Figure 3-34 Softkey Annunciations (
MSG
Softkey Labels)
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. Advisory CAS messages, flash for 5
seconds or until acknowledged.
Some CAS messages are differentiated as root causes of other failures and should be considered first during
the decision-making process when multiple CAS messages are displayed. These “golden” messages flash until
acknowledged and remain in inverse video after being acknowledged manually.
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.
CAS messages listed in tables 3-3 and 3-4 are shown in the acknowledged state (colored text on black
backgrounds), with Caution and Advisory “golden” CAS messages shown in black text on colored backgrounds
corresponding to their alert levels.
