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 transponder. The System Overview Section provides a block diagram description
of the Audio Panels and CNS system interconnection.
CNS operation in the Kodiak 100 aircraft is performed by the following Line Replaceable Units (LRUs):
• Primary Flight Display (PFD) (2)
• Multi Function Display (MFD)
• Integrated Avionics Unit (2)
• Audio Panel (2)
• Mode S Transponder
The MFD/PFD controls are used to tune the communication transceivers and navigation radios.
The two Audio Panels provide the traditional audio selector functions of microphone and receiver audio
selection. Each Audio Panel includes an intercom system (ICS) between the pilot, copilot, and passengers, a
marker beacon receiver, and a COM clearance recorder. Ambient noise from the aircraft radios is reduced by a
feature called Master Avionics Squelch (MASQ). When no audio is detected, MASQ processing further reduces
the amount of background noise from the radios.
The Mode S transponder is controlled with softkeys and the FMS Knob located on the Primary Flight Display
(PFD). The Transponder Data Box is located to the left of the System Time Box. The data box displays the active
four-digit code, mode, and reply status (Figure 4-1).
