Primary Power

Avionics layout, test panel fab, and bus layout planning

A lot of work here. First I fabricated a second mock panel. Based off the corrections needed from the first mock panel. This has enabled me to really nail the spacing of my instruments. Further it has enabled me to get the main GDU screen almost perfectly centered. I’m really happy with the symmetry of this panel.

Next up was figuring out exactly how to lay out the avionics behind the panel, and where to place the busses. A lot of this work was literally moving something and then staring at it for awhile, then moving something else. After a lot of trial and error I got what I wanted.

I also continued fabrication of the avionics shelf that will be behind the instrument panel.

Finally, I did some bench testing power-ups of all the avionics.

Electrical System Planning

I spent an enormous amount of time pouring over the Aeroelectric Connection book and associated diagrams. The closest diagram to what i wanted to achieve is Z-19 pictured below. This is the basis of my primary power system architecture. Some other choices I made. I have a B&C Alternator which means i have their external voltage regulator. I wanted to uses fuse buses not circuit breakers. I wanted to have two batteries and one alternator, not the other way around.

I used hefty diodes to isolate my main and aux battery and associated busses.

Here is my hand drawing of my primary power system modified to my needs from the Z-19. I plan to get this put in electronic format at some point in time.
