APPENDIX B AIRFRAME SPECIFIC INSTALLATION GUIDANCE (G900X Only)
B.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 G900X. 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 GRS 77 and GMU 44 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 Section 7.7 when choosing an
appropriate mounting location for the GRS 77 and GMU 44. In addition to reviewing the
guidance provided in Section 7.7, the installer should use the Garmin GLS tool to
conduct a GMU 44 site evaluation prior to permanent installation of the GMU 44
mounting bracket. The GLS tool can be downloaded from my.Garmin.com. Please
contact your G900X dealer for additional information on setup and use of the GLS tool.
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 fail completely. The guidance of FAA advisory circulars AC
43.13-1B and AC 43.13-2A may be found useful.
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
suite their particular installation.
