I began drilling the systems holes in my left wing ribs tonight and realized that I should make sure that I have enough room for the systems my plane will have. I am not doing anything that hasn't been done before, so probably someone has already sorted this out.
Here's the inventory of what needs to go through the wings:
* Standard wiring harness
* 2 wires in left wing (pitot heat ground, taxi light)
* 1 wire in right wing (taxi light)
* Coax cable in right wing for nav antenna in wingtip
* Pitot and AOA tubing in left wing, all the way to the subpanel since the ADAHRS will be there
* Garmin magnetometer in left wing ADAHRS mount
I think that I can run the pitot line in the upper aft systems holes of the left wing all the way to the root, the AOA line in the lower aft systems holes, and the nav antenna cable in the lower aft systems holes of the right wing through the first 8 ribs and the forward systems hole in the remaining 6 ribs.
The only conflicts I see in that plan come from the ADAHRS wiring harness, which connects to the magnetometer in the Garmin installation. That is supposed to run in the lower aft systems holes in the second, third, and fourth ribs of the left wing. It seems likely that the wires will be long enough to run it along with the main wiring harness in the forward systems holes.
In the right wing, there is no conflict, the coax cable would just cross over the main wiring harness between the sixth and seventh ribs.
What have others with Garmin avionics and a wingtip nav antenna done?
