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 transponder. The System Overview Section provides a block diagram description

of the Audio Panels and CNS system interconnection.

CNS operation in Kodiak 100 aircraft is performed by the following Line Replaceable Units (LRUs):

• GDU 1040 Primary Flight Display (PFD) (2)

• GDU 1040 Multi Function Display (MFD)

• GIA 63 Integrated Avionics Units (2)

• GMA 1347 Audio Panel (2)

• GTX 33 Mode S Transponder

The PFD/MFD controls are used to tune the communication transceivers and navigation radios.

The Audio Panels provide the traditional audio selector functions of microphone and receiver audio selection.

The Audio Panels include 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).
