Garmin G3X Avionics System, General
This section provides an overview of the Garmin G3X touch System.
MFD1 is installed in the rear instrument panel, MFD 2 (optional) in the front instrument panel.
Each Multi-Function Display (MFD) displays the following functions:
1.
Engine monitoring
2. Fuel Quantity and Flow indication
3. Electric system monitoring
4. Structure Temperature indication
5. Electronic Flight Instruments indication
6. Own-ship position Indication, signal from XPDR
7. ADS-B in / Traffic Indication, signal from XPDR
8. FIS-B information indication, signal from XPDR
9. VHF Interface
10. XPDR Interface
The G3X system consists of several sub-units or Line Replaceable Units (LRUs).
LRUs have a modular design, simplifying troubleshooting and maintenance.
A failure or problem can be isolated to a particular LRU, which can be replaced individually.
Each LRU has a particular function, or set of functions, that contributes to the system’s operation.
A configuration module in mounted to the main connector of the MFD1. This module stores those data not
accessible / changeable by a user, for example engine limitations. This module allows exchange of any of the
system components (Line Replaceable Units) without compromising the setup or calibration.
None of the units require regular maintenance.
For troubleshooting, refer to section 40-06 , or the Garmin G3X Touch Installation Manual, 190-01115-01,
March, 2018, Revision AE. If a problem cannot be resolved following those procedures, replace defective unit
or contact Game Composites.
VHF and Transponder are connected to MFD 1 and MFD 2, to allow use of their functions via the touchscreen,
also allowing the front seat occupant to monitor and interact with those devices.
Connection between MFD1, MFD 2 and VHF is a CAN bus.
Between transponder and the GSU 25, connection is a RS232 bus.
From there, GPS, weather and ADS-B information are forwarded to MFD1 and MFD 2.
The VHF and transponder standard pilot interfaces remain unchanged.
In case of power failure of either or both MFDs, VHF and XPDR can be used normally.
Use of the standard interface overrides the touchscreen commands. The frequency selection is slaved, i.e.
MFD1, MFD2 and the VHF and XPDR frequency indications match.
MFD1, MFD2, and the GEA 24, GMU 11 and GSU 25 have individual power supply and are secured by one
circuit breaker each, located on the RH side console in the rear cockpit.
MFD1 in the rear instrument panel, the GEA 24 and the CO sensor are activated by the Battery Master Switch,
to provide structural temperature indication (part of the pre-flight check per AFM) and engine information
required for engine start.
All other devices are activated by the Avionic Master Switch.
