CAUTION ADVISORY SYSTEM (CAS) / ALERTS

See the individual aircraft Pilot Operating Handbook (POH)
Supplement for any limitations with respect to AeroNav
operations.
A caution-warning alerting system (CAS) has been included in
this system. There are three levels of message alerting:

Warnings – Immediate action should be performed

Cautions – Immediate attention should be applied

Advisories – A change in system state that you should
be aware of

MASTER CAUTION LAMPS

A "Master Caution" system has been created where any active
Warnings will trigger a red "AUX" lamp along the bottom edge of
the bezel and any active Cautions will trigger an amber (yellow)
"AUX" lamp along the bottom edge of the bezel. Likewise, any
active Advisories will trigger a cyan (blue) "AUX" lamp along the
bottom edge of the bezel. Each time a new Warning or Caution or
Advisory condition exists, the AUX lamp will flash the appropriate
color until either it is acknowledged by the pilot or the condition
goes away. The AUX lamp will stay lit with the color that
represents the highest level of alert for Warnings and Cautions. If
the AUX page is already the current page, then the AUX lamp
stays green and the ALERT tab will follow the coloring behavior
just described. Note that if there is an active alert in the system
and a new one of a lower color priority level also becomes active,
the AUX/ALERT tab color will not change (e.g. a new cyan
advisory will not cause the tab color to change from yellow to
cyan).
For those aircraft that have a remote annunciator panel installed,
the AeroNav will trigger a "MSG" lamp or its equivalent on the
remote annunciator unit for each new CAS alert.
In all cases, basic airmanship should be exercised and
fundamentals utilized such as maintain aircraft control, analyze
the situation, and take proper action.
