The 350 Audio Panel, installed on the center console below the Flight
Management System Keyboard, integrates NAV/COM digital audio,
intercom and marker beacon controls. The VHF communications
portion of the unit interfaces with both Integrated Avionics Units to
provide external radio communication, receive and demodulate VOR,
Localizer, and Glide Slope signals.
28 VDC for Audio Panel operation is supplied through the 5-amp
AUDIO PANEL circuit breaker on the AVIONICS bus.
COM swap mode is not available in this installation.
For a detailed operating instructions, refer to the GMA 350 Audio
Panel Pilot's Guide.
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.
