Chapter 22 – Electrical & Avionics Banalities

So I’ve been working on my electrical system. I upgraded my electrical system diagrams from a Garmin GNS430W to the GTN650. I figure by the time I buy my main Nav GPS I won’t be wanting technology that’s on Garmin’s eventual chopping block for support. Of course with the move to the GTN650, I had to add two more Circuit Breakers to the panel since it’s a mandatory requirement for them that you use CBs and not fuses. Although admittedly two CBs for 7 wires is not bad.

I’ve also been spending some time on my throttle and stick (HOTAS) switches.  I reconfigured a number of switches between panel, throttle and stick, and in doing so was able to get rid of a couple panel switches.

Right now I’m thinking that if one has the panel real estate that the new Garmin G3X Touch is the way to go. As for me, I’m not burning that much real estate for an EFIS display. I decided that quite a while ago when I made a decision to forego the 10.4″ GRT HXr PFD for GRT’s much more manageable 8.4″ or 6.5″ PFD. Plus, as awesome as Garmin is, those bubbas tend not to play well with others’ stuff. I guess it’s a good marketing strategy, but picking up and using cool & useful third party stuff with Garmin can be problematic if ‘Big Brother G’ simply says, “No, you can’t use that crap with our suite of technological goodies! Here, use this nice GARMIN thing X instead!”

Also, now that I’m getting significantly closer to my final instrument panel and electrical system configuration, I’ve started building all my Wire Book templates.  I have about 20 total templates currently completed for all the various electrical subsystems, and I’ve built 5 system diagrams from these templates so far.  It should be slow steady progress over the next few months since each one that I build helps with building the remaining ones.
