Subject: | Just Two Days Left... |
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!

Therefore, the builder can expect that the initial airworthiness
inspection of his aircraft will require evidence that this type of
equipment in the aircraft is acceptable to the FAA.
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 noted the appearance of url links intended to

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!

I think the solution is quite clear. 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.

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.

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.

I'll be hitting the asphalt about Oh-Dark-Thirty in
the morning for an appointment with some of our
brothers in Columbus, Ohio next Saturday and
Sunday. I'll be stopping in Cincinnati on the
way back for a day . . . can't pass THAT close
to my sister's house without stopping for a visit.
Plans call for me to be back on line about Tuesday
afternoon.
BTW, we have a new addition to the family tree.
Our 5th grandchild, Calvin Aaron Douglas was born
last Friday just before midnight. THIS one lives
in the same town as I do . . . got great plans
for this little feller!
