Current progress

One of the cool things about this stage of the project is that after a few hours of wiring I can turn on some part of the RV’s avionics and see it work.

For instance, I’ve had these Oplite 6 LED lights for several years now and finally got them wired up to the Garmin GAD-27 as instrument panel lights, so they’re controllable by a dimmer on the panel. These lights are really rugged and when driven by one of the GAD-27’s PWM lighting controllers, they’re dead quiet too – no hash on the radio like I’ve encountered with some other dimmers. Very cool.

I’ve also had Whelen LED nav/strobe lights sitting around for a few years, waiting for installation. The tail nav/strobe is finally wired through to the cockpit, and here’s some video to show how damn bright they are…low current draw too, and no need for a heavy strobe pack like older nav/strobe lighting systems.

Next on the list was wiring the flap motor, but I need some hardware to fabricate a mounting bracket. So, I jumped ahead to wiring the Advanced Flight Systems Angle-of-Attack (AoA) system. This is the only “legacy” avionics system on the airplane, as Advanced doesn’t sell it anymore. I hope it doesn’t fail.

For those of you who aren’t into aerodynamics, AoA is the angle at which the wing meets oncoming air, thus generating lift. If AoA exceeds a certain value, the wing stalls and lift is drastically reduced – so you can see why knowing AoA might be important for staying in the air. If you’re really into the concept, watch this video.

AoA is alive!

Everything lights up, and the self-test lady says the system is working…

Of course with all the gee-whiz stuff lit up, I had to take a picture. Enjoy!

A thing of beauty
