If your battery and engine are on the same end of the airplane, #4 would probably be fine for all of your "fat" wires . . . #2 would certainly be okay.

If one is primarily interested in opening, editing, saving and printing AeroElectric Connection .dwg files, then any version 7 or later will work. The last V7 I purchased of Ebay was $10 plus postage. Obviously, if one needs the more advanced features of a later version, the $higher$ editions are indicated.

Because the B&C devices are not just "regulators" . . . they contain OV protection, alternator regulation AND LV Warning. Further, these regulators conform to design goals that have become pretty much standard over the last 20+ years: DON'T MAKE FIELD SUPPLY AND VOLTAGE SENSE LINES TO THE BUS SHARE A COMMON CONDUCTOR. This is called, "remote sensing for voltage regulation". This prevents the very common ammeter oscillation phenomenon common in many light aircraft of yesteryear. It also insures that the LV warning system stays operational even if the alternator has been taken off line manually or by reason of an OV condition.

This quote is from their website "AirplanePDQ is a conceptual/preliminary design tool for light homebuilt and general aviation aircraft." I use it to translate newer ACAD files to the R14 version that I use. http://www.davincitechnologies.com/ -- Ralph C.

With the web you have advice of many, and everyone is in such agreement, plus lots of excellent advice, you should be encouraged. 1 Go to different shop 2 Call EAA, get all the regs references to back you up. 3 Call the FAA and politely ask, "educate me?" 4 Than challenge FAA to advice shop its OK. (EAA not sure they make calls for you, but their legal will advise you.) Once you educate them if you have, they will know they're wrong and it would make them look bad; they will agree and tell the shop it's OK to do a Pitot Static test. That is ALL it is a TEST for accuracy, not certification of the equip. Sometimes its ego and they don't want to back down, but they will if you have the information. It's not even a gray area. They are wrong. Some times you have to take a stand. Be an advocate for all EAA'ers. You can do it and it will not take that much time. You can do it all on the phone most likely. Here are some Reg Ref links for FUN? Sec. 91.215 ATC transponder and altitude reporting equipment and use. http://www.ferrer-aviation.com/far91215.htm Sec. 91.217 - Data correspondence between automatically reported pressure altitude data and the pilot's altitude reference. http://www.ferrer-aviation.com/far91217.htm TSO-10b (altimeter) http://tinyurl.com/2f8rla TSO-C88 (alt reporting / digitizing) http://tinyurl.com/2ez4a3 Don't panic, when you see TSO. It's a definition and many sections of part 91 Ref. part 21, 23, 34, 43, 47 & TSO's to name a few. None (almost) apply to experimentals. --------------------------------- Never miss a thing.

Great thread on BMA. Check out page 2 and even more page 3, which are most relevant. http://tinyurl.com/2au2pe Paper on legality of experimental EFIS (encoder, altimeter, GPS, aka none TSO) in experimentals. http://tinyurl.com/2fbloa Bottom line is the pitot/static test is not an approval of the equip. As the builder you state it meets the TSO. I posted on Dynon's forum the same question. Some manufactures like GRT say their encoder meets the TSO. --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
