GTX 345 Mode S Transponder w/ UAT in
The GTX 345 solid state transponder communicates with the primary Inte-
grated Avionics Unit, provides Modes A and C interrogation/reply capabil-
ities, and performs the following functions:
• UAT Reception: The GTX 345 receives ADS-B, ADS-R, and TIS-B
data transmitted on the 978 MHz frequency from other aircraft, vehi-
cles, and ground stations for traffic awareness. In addition, the GTX
345 receives FIS-B data to provide graphical and textual weather prod-
ucts.
• Mode S Extended Squitter (ES) Reception: The GTX 345 receives
ADS-B data transmitted by aircraft on the 1090 MHz frequency for
traffic awareness.
• Output of graphical traffic and weather data to the MFD and PFD
(ADS-B IN).
The transponder is controlled via the PFD or Flight Management System
Keyboard and is located in the empennage avionics compartment.
28 VDC for Mode S Transponder operation is supplied through the 2-amp
XPONDER circuit breaker on AVIONICS. Refer to the Perspective+ Inte-
grated Avionics System Pilot's Guide for a complete description of the
system, its operating modes, and additional detailed operating procedures.
GSR 56 Iridium Satellite Network Transceiver
The Iridium Satellite Network Transceiver, mounted in the empennage
avionics compartment, communicates with the primary Integrated
Avionics Unit and Audio Panel to provide near real-time weather, voice,
and data services to the cabin audio system and integrated displays. The
GSR 56 receives near real-time satellite weather information for display on
the MFD and PFD and can also provide telephone/voice communications
and text messaging (SMS) through the Iridium Satellite Network. The voice
service is available through the audio panel via the TEL (telephone) input
selection. SMS and weather products are displayed on the MFD.
28 VDC for Iridium Satellite Network Transceiver operation is supplied
through the 5-amp DATA LINK/WEATHER circuit breaker on
AVIONICS. Refer to the Perspective+ Integrated Avionics System Pilot's
Guide for a complete description of the system, its operating modes, and
additional detailed operating procedures.
GDL 69A XM Satellite Weather and Radio
The Data Link Satellite Receiver, mounted in the empennage avionics
compartment, receives and transmits real-time weather information to the
MFD and PFD. This unit also provides digital XM audio entertainment to
the cabin audio system via the audio panel. It is controlled by MFD or the
Flight Stream 510 Wireless Avionics Interface.
