Appendix A Airframe Specific Installation Guidance - Garmin G3X Installation Manual

APPENDIX A AIRFRAME SPECIFIC INSTALLATION GUIDANCE

A.1 Introduction
Garmin has included in this manual some installation guidelines to aid the builder in the placement of
various units which make up the G3X. It is at the discretion of the builder whether he or she wants to
follow a typical layout or design an installation completely unique to their aircraft. The following
information is provided as guidance only and does not account for variations in specific installations.
NOTE
Although the potential GMU 22 mounting locations shown in this manual have been tested
on appropriate type aircraft, Garmin cannot take into account the wide variation of
aircraft specific installations and therefore cannot guarantee the provided locations will
work for all installations in a particular aircraft type. Garmin strongly recommends the
installer conduct a thorough review of
mounting location for the GMU 22. In addition to reviewing the guidance provided in
Section 13.4, the AHRS/Magnetometer Installation Considerations document (which
contains instructions) can be downloaded from the Dealer Resource Center portion of the
Garmin website www.garmin.com.
NOTE
The typical installations contained in this manual are known to fit each aircraft. In
addition, custom brackets and mounting which should be incorporated to properly support
the units are detailed in the typical installation. Unsupported avionics or inferior
mounting brackets can contribute to cracking of the mounting trays or a unit becoming
dislodged, intermittent or to fail completely. The guidance of FAA advisory circulars AC
43.13-1B and AC 43.13-2A may be found useful.
NOTE
It is recommended the builder at least review the typical installation prior to embarking on
his/her own design, and determine what additional components may be required to suit
their particular installation.
A.1.1 GMU 22
The integrity and reliability of the G3X heading and attitude information is entirely dependent upon the
installation quality of the GMU 22 Magnetometer. Garmin strongly recommends the purchase of the pre-
fabricated parts indicated in Table . Failure to use Garmin approved brackets may result in severe
degradation of system performance. Garmin cannot guarantee acceptable system performance if any
variations from these designs are made. It is essential that installation accuracy requirements specified in
the following sections be maintained in any GMU 22 installation, if the installer chooses to follow the
typical installation guidance.
