AUDIO PANEL AND CNS
SECTION 4 AUDIO PANEL AND CNS
4.1 OVERVIEW
The Communication/Navigation/Surveillance (CNS) system includes the Audio Panels, communication radios,
navigation radios, and Mode S transponders. The System Overview Section provides a block diagram description
of the Audio Panels and CNS system interconnection.
CNS operation in the Embraer Phenom 100 is performed by the following Line Replaceable Units (LRUs):
