SR22 Airplane Description
NAV 1 – The upper GARMIN GNS 430 is designated NAV 1. 28 VDC
for navigation receiver operation is controlled through the Avionics
Master Switch on the bolster switch panel and supplied through the 5-
amp GPS1 circuit breaker on the Avionics Essential Bus row.
NAV 2 – The lower GARMIN GNS 430 is designated NAV 2. 28 VDC
for navigation receiver operation is controlled through the Avionics
Master Switch on the bolster switch panel and supplied through the 5-
amp GPS 2 circuit breaker on the Avionics Non-Essential Bus row.
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.

Airplane Description SR22
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
headsets is controlled by the individual audio selector switches on the
audio control panel and adjusted for volume level by using the selected
receiver volume controls.
Audio Input Jack
Two audio input jacks are provided on the aft portion of the center
console. One jack is located near the convenience outlet for use by the
pilot and forward passenger, and another is located further aft by the
rear passenger ANR power jacks. These jacks can be used to plug in
personal entertainment devices such as portable radios, cassette
players, or CD players. Audio volume through these jacks is controlled
by connected individual entertainment device.
Emergency Locator Transmitter
The airplane is equipped with a self-contained emergency locator
transmitter (ELT). The transmitter and antenna are installed
immediately behind the aft cabin bulkhead to the right of the airplane
centerline. The main transmitter control switch, labeled ON-OFFARMED,
on the transmitter is in the armed position for normal
operations. A remote switch and indicator panel is installed
immediately below the circuit breaker panel. The transmitter unit is
mounted longitudinally in the airplane in order to detect deceleration
greater than 3.5 ft/sec. If rapid deceleration is detected, the transmitter
will repeatedly transmit VHF band audio sweeps at 121.5 MHz and
243.0 MHz approximately 0.5 seconds apart. The transmitter and
portable antenna are accessible through an access at the base of the
baggage compartment bulkhead. The ELT can be removed from the
airplane and used as a personal locating device if it is necessary to
leave the airplane after an accident. Eight dated “D” cell alkaline
