Airplane Description SR20
Transponder
The airplane is equipped with a single Garmin GTX 327 ATC Mode C
(identification and altitude) transponder with squawk capability. The
transponder system consists of the integrated receiver/transmitter
control unit, an antenna, and an altitude encoder. The receiver/
transmitter receives interrogations from a ground-based secondary
radar transmitter and then transmits to the interrogating Air Traffic
Control Center. Digitized altitude information, provided by the altitude
encoder, is plumbed into the airplane static system. The transponder
and integrated controls are mounted in the center console. The
transponder control provides active code display, code selection,
IDENT button, and test functions. A FUNC (function) key allows for
selection of pressure altitude, flight time, count-up timer and
countdown timer modes. The display is daylight readable and dimming
is operator controlled through the INST lights control on the instrument
panel bolster. The transponder antenna is mounted on the underside
of the fuselage just aft of the firewall. 28 VDC for transponder
operation is controlled through the Avionics Master Switch on the
bolster switch panel. 28 VDC for receiver, transmitter, and altitude
encoder operation is supplied through the 2-amp ENCODER/
XPONDER circuit breaker on the Avionics Non-Essential Bus.
Audio System
The airplane is equipped with a Garmin GMA 340 Audio Panel.
Refer to the Garmin GMA 340 Audio Panel Pilot's Operating
Handbook, P/N 190-00149-10 Rev C or later, and the applicable POH
supplement for a more complete description of the autopilot, its
operating modes, and additional detailed operating procedures.
Headset/Microphone Installation
The airplane is equipped with provisions for four noise-canceling
headsets with integrated microphones. The forward
microphone-headsets use remote Push-To-Talk (PTT) switches
located on the top of the associated control yoke grip. The rear
headsets do not have COM transmit capabilities and do not require
PTT switches. The microphone (MIC), headset, and automatic noise
reduction (ANR) power jacks for the pilot and front seat passenger are
located in the map case and similar jacks for the aft passengers are
located on the aft portion of the center console. Audio to all four
