Annunciation and Alert System
Aircraft annunciations and alerts are displayed in the Crew Alerting System
(CAS) window located to the right of the altimeter and VSI. Aircraft
annunciations are grouped by criticality and sorted by order of appearance
with the most recent message on top. The color of the message text is based
on its urgency and required action:
•
Warning (red) – Immediate crew awareness and action required.
• Caution (yellow) – Immediate crew awareness and future corrective
action required.
• Advisory (white) – Crew awareness required and subsequent action
may be required.
In combination with the CAS Window, the system issues an audio alert
when specific system conditions are met and an expanded description of
the condition is displayed in the Alerts Window located in the lower RH
corner of the PFD.

For specific pilot actions in response to System Annunciations,

matic Flight Control System, for operating information.
Approach Baro-VNAV
While executing an LNAV/VNAV approach with SBAS unavailable,
Baro-VNAV is used for vertical approach guidance. This occurs due to any
of the following conditions:
•
SBAS fails or becomes unavailable prior to final approach fix (FAF)
• the aircraft is outside SBAS coverage
• SBAS is manually disabled on the GPS Status page (To simulate a
Baro-VNAV approach, SBAS must be manually disabled prior to acti-
vation of the approach procedure.)
Baro-VNAV is also the source of vertical approach guidance if the
LNAV/VNAV procedure does not support SBAS vertical guidance.
While Baro-VNAV is being utilized, the Glidepath Indicator appears as a
magenta pentagon. If the approach type downgrades past the FAF, “NO
GP” is displayed in place of the pentagon.
