1.2 LINE REPLACEABLE UNITS
•
GDU 1040 (2)
– A GDU 1040 is configured as the Primary Flight Display (PFD) and the Multifunction Flight
Display (MFD). Each unit is a 10 inch, high resolution LED backlit display. The displays communicate with
each other. Each display is also paired with the on-side Integrated Avionics Unit (IAU).
• GMA 1347
(1)
– The Audio Panel integrates navigation/communication (NAV/COM) digital audio, intercom,
and marker beacon controls, and is installed between the displays. The GMA 1347 also provides manual
control of display Reversionary Mode (red
DISPLAY BACKUP
Button; see further discussion later in this section)
and communicates with both IAUs.
• GIA 63W
(2) – The Integrated Avionics Unit (IAU) functions as the main communication hub, linking all LRUs
with the on-side display (GDU). Each IAU contains a GPS SBAS receiver, VHF COM/NAV/GS receivers, a Flight
Director (FD) and system integration microprocessors. Each IAU is paired with the on-side display. The IAUs
are not paired together and do not communicate with each other directly.
• GDC 74A
(1) – The Air Data Computer (ADC) processes data from the pitot/static system as well as the OAT
probe. This unit provides pressure altitude, airspeed, vertical speed and OAT information to the system, and
it communicates with both IAUs, the PFD, the MFD, and the AHRS (it also interfaces directly with the OAT
probe).
• GEA 71
(1) – The Engine Airframe Unit receives and processes signals from the engine and airframe sensors.
This unit communicates with both IAUs.
• GTX 345R
(1)
– Solid-state transponder provides Modes A, C, and S capability, as well as ADS-B In/Out. The
transponder communicates with both IAUs.
• GRS 77
(1) – The Attitude and Heading Reference System (AHRS) provides aircraft attitude and heading
information to both displays and both IAUs. The AHRS contains advanced sensors (including accelerometers
and rate sensors) that interface with the Magnetometer to obtain magnetic field information, with the ADC to
obtain air data, and with both IAUs to obtain GPS information.
• GMU 44
(1) – The Magnetometer measures local magnetic field and sends data to the AHRS for processing to
determine aircraft magnetic heading. This unit receives power directly from the AHRS and communicates with
it.
•
GDL 69A SXM
(1) – The SiriusXM Datalink Receiver provides weather information, as well as digital audio
entertainment. The receiver communicates with the MFD. A subscription to SiriusXM Weather and/or SiriusXM
Satellite Radio service is required to enable services.
•
GA 55
(1) – A stud mount XM antenna.
