SECTION 4 AUDIO PANEL AND CNS

4.1 OVERVIEW

The Communication/Navigation/Surveillance (CNS) system includes the Audio Panel, communication radios,

navigation radios, and Mode S transponder. The System Overview Section provides a block diagram description

of the Audio Panel and CNS system interconnection.

CNS operation in Diamond DA42NG aircraft is performed by the following Line Replaceable Units (LRUs):

•PrimaryFlightDisplay(PFD)

•MultifunctionDisplay(MFD)

•IntegratedAvionicsUnit(2)

•AudioPanel

•ModeSTransponder

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

The Audio Panel provides the traditional audio selector functions of microphone and receiver audio selection.

The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).
