Dear Listers, There are just a couple days left for this year's List Fund Raiser. Over all, participation has been good, but things have been pretty slow this week for some reason. If you've been putting off making your Contribution until the last minute, this is it! The last minute, that is... :-) Please remember that there isn't any sort of commercial advertising on the Lists and the *only* means of keeping these Lists running is through your Contributions during this Fund Raiser. Please make a Contribution today! http://www.matronics.com/contribution Thank you!

Regurgitating the FARs is most likely deja-vu to most builders. "Evidence" here is just as open to interpretation as the result of what King James did to the "Bible". Still best to find out how your DAR reads chapter&verse. You spent years of your life building the sumbitch, why crash&burn on judgement day?

I'll suggest that we accomplish due diligence to avoid dilution of the focus for our activities here on the list. As we move about our daily lives, it is difficult to ignore increasing pressures on our $time$ and attention for the purpose of parting us with our $time$ in exchange for something we probably don't want . . . or we would be out looking for it. It may seem like a tiny thing but all leaky pipes started with a drip and Kudzu came to the 1876 Worlds Fair being promoted as a forage crop and ornamental plant!

Since it's your goal NOT to craft and exploit the operational features of an ENDURANCE mode of flight, I suggest that the SD-8 is quite adequate to your needs. This presumes that you plan to include and artfully maintain an RG battery. There's no reason not to include the battery's capacity in your Plan-B for expediting a comfortable arrival with the earth in case of alternator failure. Using the battery to augment the SD-8 by a couple of amps is a perfectly valid thing to consider too. Installing an SD20 goes more to servicing an endurance mode limited only by volume of fuel aboard. In any case, Z-12 or Z-14 are my best recommendations for incorporating the SD-20 into a robust architecture.

That's my plan. Fusible links have never been suggested as a general replacement for other protective devices. The instances where the fusible links are shown in the Z-figures are limited to low risk applications where the I(squared)T robustness of an ANL style current limiter is attractive. To stir breakers/fuses into the discussions about fusible links is to brush aside the reason the fusible links were suggested. They are STILL my best recommendation for extending the main bus fuse block out to the alternator field breaker in systems where crowbar OV protection is present (obviously not necessary when one chooses to use breakers on the main bus) AND as a b-lead protection for the smaller PM alternators. They're also okay for long service life protection of instrument leads off of an ammeter shunt. I think I've made this clear in numerous postings where a readers were asking about expanding on usage of fusible links. I have published instructions and offered sources for materials to properly craft fusible links in the smaller sizes appropriate to our needs. http://www.aeroelectric.com/articles/fuselink/fuselink.html Also check out the writings at: http://www.aeroelectric.com/articles/anl/anlvsjjs.html http://www.aeroelectric.com/Reference_Docs/Misc_PDF/9021704F.pdf I've conducted numerous tests on the effectiveness of the fusible links for use as suggested. Concerns for "arcing" and "rupture" and "plasma blowing holes" are interesting and perhaps exciting to contemplate but the reality is quite pedestrian.
