WARNING-CAUTION-ADVISORY MESSAGE BAR
A message bar is provided on every AeroNav to alert the pilot to
what the CAS message is. Advisories are displayed on a cyan
(blue) background in the lower right corner of each AeroNav.
Warnings are displayed on red background in the lower right
corner of each AeroNav. Likewise, Cautions are displayed on an
amber background in the lower right corner of each AeroNav.
Red warnings will always display on top of amber cautions and
amber cautions will always display on top of cyan advisories.
Warning Message
Pressing the “CLR” bezel key or touching the message bar on the
display will acknowledge the message but will not do anything
else.
After all active messages have been acknowledged, the AUX
lamp will remain illuminated with the color of the highest priority
message.
In dual AeroNav installations, there is a concept of global vs. local
CAS messages. Global messages stay synched across all
AeroNavs and will be displayed on all AeroNavs and can be
acknowledged on any AeroNav to dismiss the message on all
AeroNavs. Local messages only apply to the AeroNav on which
it is displayed and can only be acknowledged on the individual
AeroNav. The table of system CAS messages that appears later
in this section indicates global messages via an asterisk.
