It took a few months but I just completed installation and configuration of a dual screen Garmin G3X Touch system.
This install is in an RV-7A, Slider.
I couldn't be happier!
Installation went well thanks to the great wiring harness that was built by John Stark and Jonathan Dalafave at Stark Avionics
The system includes all the standard components:
(2) GDU 460 moving map screens
GSU 25 AHRS
GTP 59 temperature probe
GMU 22 magnetometer
GAD 29 ARINC adapter
GEA 24 engine analyzer
In addition I added:
GTN 750 nav/com/waas gps/map
GTR 20 remote com
GMA 240 audio panel
GMC 305 autopilot control
Trutrak GX Pilot (I'm using Trutrak servos)
GDL-39R remote ADS-B receiver
Advanced Flight Systems AOA Sport
GTX 23 remote transponder
ACK Model E-04 ELT
Vertical Power VP-X Sport
The labeling was done with dry transfers from Color Vu
in Southlake, TX. The panel was cut by Steinair
and they did an outstanding job.
The annunciator panel was my own creation using information I gathered from other Van's Air Force contributors
I received some great help from the Garmin G3X Team
when I ran into a couple of problems. How they figured out that I had two pins reversed on the CAN bus with the little bit of information I gave them on the phone is little short of a miracle. These folks are amazing!
The most difficult part of the job was figuring out where to place all the components...it was really becoming crowded behind the panel by the time I had finished. Click here
and scroll down to Post #36 to see behind the panel pictures.
Here are some additional pictures of the panel details:
are wired to provide multiple functions described in Bob Nuckolls, "AeroElectric Connection"
The black circular socket on the bottom right is a LEMO jack
for Bose headsets.
The mini toggle switch just to the right of the LEMO jack selects for mono or stereo headsets.
The dual Pmag ignitions
have locking toggle switches for run and test modes. The Start switch
has red LED surround lighting.
The wiring for the DPST TO/GA Switch
is described in the G3X Installation Manual. The Flap switch is from DigiKey
The annunciator panel is made from 12mm x 16mm LED display units
with a clear label under the cap.
The GMC 305 autopilot controller at the bottom of the center stack is fully integrated with the G3X and the Trutrak GX
Left and Right Aux Fuel Switches control the operation of Auxiliary Fuel Pump Relays
from Aircraft Extras.
A backup battery is wired in the "AUTO" mode to disconnect from the main power bus
should the main battery drop below 13 volts.
I am still learning all the new and amazing things this system can do. I just noticed today that I was seeing aircraft on the moving map screen that were flying over me on approach to DFW. And this was from inside my shop with the ADS-B antenna on the bottom of the fuselage!
This equipment is truly astounding. It's true what Arthur C. Clarke said, " Any sufficiently advanced technology is indistinguishable from magic".
