WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain function. The G3X Terrain Proximity feature is NOT intended to be used as a primary reference for terrain avoidance and does not relieve the pilot from the responsibility of being aware of surroundings during flight.
Page 7
Although unlikely, it may be possible for erroneous operation to occur without a fault indication shown by the G3X. It is thus the responsibility of the pilot to detect such an occurrence by means of cross- checking with all redundant or correlated information available in the cockpit.

System Overview SECTION 1 SYSTEM OVERVIEW The G3X System presents flight instrumentation, position, navigation, communication, and identification information to the pilot using 7” Wide VGA (800x480) flat-panel color display(s). 1.1 LINE REPLACEABLE UNITS The system is distributed across the following Line Replaceable Units (LRUs): •...
System Overview • GSU 73 Garmin Sensor Unit sub-system for the G3X (Air Data Computer (ADC), Engine/ – Airframe Unit, and the Attitude and Heading Reference System (AHRS)) – ADC: Processes data from the pitot-static system and outside air tem- perature (OAT) sensor.

A typical upgraded panel would have the left GDU configured as a full-screen PFD and the right GDU configured as a full-screen MFD. The following is an example of a upgraded G3X panel using a GDU 370 and a GDU 375; however, two GDU 370s can be used if XM is not needed.
When using an external GPS navigator with the G3X, press the INTERNAL Softkey on the Active Flight Plan Page or Direct-To Page to make changes to the active flight plan from the G3X. Press the EXTERNAL Softkey to return to the external GPS navigator’s flight plan.
Non-WAAS external navigators do not support MapMX. Refer to the G3X Installation Manual for more information. EXTERNAL GPS NAVIGATOR FAILURE In the event that all configured external GPS navigators fail, the G3X reverts to its internal VFR GPS for navigation and flight plan modification. INTEGRATED AUTOPILOT (OPTIONAL) The G3X can also communicate with various third-party external autopilot units.
NOTE: Refer to Appendix C for more information on SD Card use and databases. The G3X data card slot uses Secure Digital (SD) cards and is located on the upper right side of the display bezel(s). The SD card can be used for software updates, checklist files, flight data logging, exporting Track Logs/User Waypoints, and Importing/ Exporting Flight Plans.

If the MFD fails, PFD1 and PFD2 enter reversionary mode. A failure of PFD2 is not considered an emergency and will not cause either of the remaining displays to enter reversionary mode.
All instruments should be operational within one minute of power- up. If any instrument remains flagged, and it is not likely an installation related problem, the G3X should be serviced by a Garmin-authorized repair facility . PFD Initialization 190-01115-00 Rev.
AHRS OPERATION The Attitude and Heading Reference System (AHRS) performs attitude, heading, and vertical acceleration calculations for the G3X System, utilizing GPS, magnetometer, and air data in addition to information from its internal sensors. Attitude and heading information are updated on the PFD while the AHRS receives appropriate combinations of information from the external sensor inputs.
NOTE: Flight Log and Track Log must be accessed from the MFD in a Multiple Display system. The G3X has a dedicated MENU Key. Press once to display a context-sensitive list of options for the page or the dedicated PFD. Press twice to display the Main Menu.
