Not to impugn the FAA too severely; they write a lot of regulations and most are pretty readable. But there are some that are obviously written by committee; and I suppose, meant to be read by one too. Usually someone on the committee knows the real poop and so the words are just sort of scrambled around then thrown into a document when they smell about right. Nobody reads this stuff. Here's another example (I swear it's true): "Sec. 23.1395 No position light intensity may exceed the applicable values in the following equal or exceed the applicable values in 23.1389(b)(3):" Ayn Rand: "Did you really think we want those laws observed?" said Dr. Ferris. "We want them to be broken.... There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law-abiding citizens? What's there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced or objectively interpreted and you create a nation of law-breakers and then you cash in on guilt. Now that's the system, Mr. Reardon, that's the game, and once you understand it, you'll be much easier to deal with." ('Atlas Shrugged' 1957) Regards, Eric M.

Thanks Bob. I've got the parts for making the filter and will start there first. Looks like I'm going to have to send the radio to Australia so it might be a while till I can see what effect the filter will have. Thanks again.

I guess for fault tolerance reasons there is also a separate "aux avionics switch" with a separate breaker that can bypass the avionics solenoid and feed the avionics bus directly. This seems to add a level of complexity that provides very little if any benefit. There are only three pieces of avionics, a GNC250XL(10A), a GTX320(3A) and an intercom(1A). The aux avionics breaker is 15 Amps. As they say "if it ain't broke don't fix it". In this case I'm not trying to fix it, I'm trying to add a Trutrak autopilot and I'm trying to figure out the best way to wire in the power. The quickest would be to feed it separately from the main bus and not use the avionics bus. The most complex would be to re-wire the entire plane using a Z-drawing type configuration. I'm looking for a in-between solution, preferably closer to the first idea. Any thoughts? Thanks Ken DO NOT ARCHIVE ________________________________ Message 6 _____________________________________ Time: 03:07:38 PM PST US From: rv-9a-online Subject: Re: AeroElectric-List: Avionics breaker --> AeroElectric-List message posted by: rv-9a-online I think that you should wire it directly to the main bus with a switch and the rated breaker or fuse. You need the switch in case you have an 'insane' autopilot.
