That's the old "fat" file. Here's the trimmed file
I posted later:
http://www.aeroelectric.com/PPS/ACAD_Symbols_Library/0_ACAD_All_Symbols.zip
Also, be aware that the website is getting some much needed attention
for organization and from time to time, files may move to new folders.
You can always go directly to the folder structures by using the site
index at:
http://aeroelectric.com/Downloads.html
and explore the directories from there. In this case, you
go to "Page per System Drawings" and then to "ACAD_Symbols_Library"
that will take to the individual symbols and the .zip file of
all symbols cited above.

Actually, the roll and yaw are in opposite directions in an inverted
spin. The relative proportions of roll and yaw depend on the pitch
attitude (assuming a fully developed spin with a vertical axis of
rotation). It is a bit of a crap shoot to guess what a TC would be
showing. This is one of the reasons why I have a T&B, as I plan to
do quite a bit of aerobatics, and I can't rule out the possibility of
ending up in an inverted spin following a botched manoeuvre.
The fact that the roll and yaw are in opposite directions make
inverted spins quite disorienting. We tend to be more sensitive to
roll rate than yaw rate, so there is a tendency to misinterpret the
direction of spin. If the inverted spin is intentional, then you
probably know which way you are spinning. But, if it was
unintentional, the turn needle on a T&B is a good confirmation as to
which rudder you need to push.

Great Information Kevin,
I had no knowledge of those forces. The only inverted spin I was ever in
scared me so much that I have avoided such spins assiduously ever since.
The more I learn about the TC, the better I like the T&B!
Thanks for the input.
I have some old thoughts on this subject that I posted on another list
several years ago. Would you mind if I sent them to you for your comment?
Happy Skies,

Thanks for the link! I've seen this floating around
for a lot of years. The $10 millions seemed way out
of whack. I also recalled being able to buy the "Space
Pen" in office stores for fairly reasonable prices. Are
they still out there? Don't recall seeing one recently.

See:
http://aeroelectric.com/articles/multiplewires/multiplewires.html
It's never "incorrect" to simply solder the wires into a common joint
and cover with heatshrink. Just joints tied into wire bundles are
very long lived in light aircraft. But if you're looking for a craftsman
of the year award, the judges will no doubt bring a lot of baggage
from the TC and Mil-Spec worlds. The use of classier tools and materials
will get you some points.

Hi Bob,
The Space Pens are still available. I purchased one in a stationary
store a couple of months ago when I lost the one I'd been using for 10
years. I forget what I paid but it was under $10 although they had some
for more.

I am amazed at the number of mistakes I (we?) get-away-with, usually unknown
to anyone but ourselves (but for the grace of ...).
I could never forget the 'Master' because the machine had either:
1. big red panel light (homebuilt) or
2. a noisy electric gyro ("certified" aircraft)
But, how did that dome/map/panel light (wired direct to battery) rocker
switch unknowingly get bumped ON in bright daylight? Same effect as Master
left ON: dead battery. Would adding item "Check Dome Light Switch OFF" to a
shutdown checklist guarantee no repeat? Nope, because one day, some day, I
might miss the checklist item.

This is taking on elements of the situation described in the old story
wherein NASA spent millions developing a ballpoint pen that would allow
astronauts to write while upside down, while the Russian cosmonauts simply
used pencils.
Here's a nice quick-and-dirty and cheap 2-step solution:
1. Add "Turn off Master" to checklist.
2. Follow checklist. Which you should be doing anyway.

Hmmmm . . . I have a recent version of PKZIP.
I wonder if there are any compatibility problems
for un-zipping with older releases. I've considered
making my .zip files self-extracting but this
makes them .exe files which many folks are understandably
concerned about.
Try going to this directory:
http://www.aeroelectric.com/PPS/ACAD_Symbols_Library
2DIODBLK.DWG is an old symbol originally saved under R14 AutoCAD which
I just opened and re-saved under 2000. The thing jumped from
5K to 25K bytes (ugh!).
The one just below . . . 30SPDTRY.DWG is still in AutoCAD R14.
I'd appreciate it if you'd see how your TCv7.0 handles these
two files.
The Unzip corruption is another issue. I'll poke around on
the 'net and see if we might have a compatibility problem between
releases of PkZip.
Thanks!

One solution for something like a dome light could be to wire an auto
off feature. My newer multimeter does that. Some car dome lights do it.
In fact years ago when I tired of replacing 9v. batteries, I added such
a feature to an older multimeter using a mosfet transistor that runs
until a gate capacitor bleeds down. For all intents and purposes, the
standby current draw is zero after it times out.
A universal solution might be a buzzer that detects when more than a few
ma of current is flowing out of the battery. I'll think about it but I
don't think I know a simple way to do that such that it draws no standby
current, and doesn't add failure points to the original aircraft wiring.

Thanks for the link! I've seen this floating around
for a lot of years. The $10 millions seemed way out
of whack. I also recalled being able to buy the "Space
Pen" in office stores for fairly reasonable prices. Are
they still out there? Don't recall seeing one recently.
I've .pdf'ed the Snopes page for future reference.

Subject: | Z14 Failure Modes and the Cross-Tie |
--> AeroElectric-List message posted by: Adam Molny <Adam@ValidationPartners.com>
I'm laying out the electrical system for my all-glass, all-electric,
FADEC-powered Lancair Legacy. The Z-14 system seems like the natural way to
go, using two full-size alternators. It would be very attractive to have the
ability to power both the A and B buses and recharge both batteries from a
single alternator when needed. However, I'm having trouble imagining a
failure mode where the cross-tie could be used in flight.
If the Bus A alternator's field breaker trips in flight (for example), would
it be safe to engage the cross-tie? You don't know what caused the failure,
and tying the A and B buses together could knock out the B bus.
If you get a low voltage warning on bus A, do you pull the corresponding
field breaker and engage the cross-tie? Again, if something is shorting out
the bus (such as shorted windings on the alternator), you are in danger of
overloading bus B.
Any thoughts?

Hi Adam
I figure the most likely reason to close the crossfeed is when one
alternator simply stops producing power or has been shutdown by the OV
protection. Bus voltage will be nominal battery voltage in such a case.
With a contactor on the output of an IR regulator even the stator and
diodes are out of the circuit when I shut down an alternator or the OVP
activates but I'd expect the alternator fuse/breaker/ANL to already be
open anyway in that case. I agree that it might be unwise to close the
crossfeed if immediately after the low voltage warning you observe that
the voltage is below normal battery voltage but then again you have the
option if you need the equipment and think maybe you've got a open
circuited or disconnected battery (or open master contactor) that has
allowed a subsequent OV excursion and alternator shutdown. Plan A would
be to leave it alone til on the ground if I don't need it. Any smoke or
sparks would definately keep my finger away from the crossfeed. There
really isn't much of a "bus" on a small airplane with fuse blocks which
makes it very difficult to imagine a shorted bus. Z-14 also gives the
option of conducting a single alternator recovery flight home or to a
maintanance facility.

That's the old "fat" file. Here's the trimmed file
I posted later:
http://www.aeroelectric.com/PPS/ACAD_Symbols_Library/0_ACAD_All_Symbols.zip
Also, be aware that the website is getting some much needed attention
for organization and from time to time, files may move to new folders.
You can always go directly to the folder structures by using the site
index at:
http://aeroelectric.com/Downloads.html
and explore the directories from there. In this case, you
go to "Page per System Drawings" and then to "ACAD_Symbols_Library"
that will take to the individual symbols and the .zip file of
all symbols cited above.

really isn't much of a "bus" on a small airplane with fuse blocks which
makes it very difficult to imagine a shorted bus. Z-14 also gives the
option of conducting a single alternator recovery flight home or to a
maintanance facility.

Actually, the roll and yaw are in opposite directions in an inverted
spin. The relative proportions of roll and yaw depend on the pitch
attitude (assuming a fully developed spin with a vertical axis of
rotation). It is a bit of a crap shoot to guess what a TC would be
showing. This is one of the reasons why I have a T&B, as I plan to
do quite a bit of aerobatics, and I can't rule out the possibility of
ending up in an inverted spin following a botched manoeuvre.
The fact that the roll and yaw are in opposite directions make
inverted spins quite disorienting. We tend to be more sensitive to
roll rate than yaw rate, so there is a tendency to misinterpret the
direction of spin. If the inverted spin is intentional, then you
probably know which way you are spinning. But, if it was
unintentional, the turn needle on a T&B is a good confirmation as to
which rudder you need to push.

Bob,
Didn't get a chance to see if TC v 7.0 would open the libray because I got a corruption
message when I tried to unzip the symbol file. I've had no trouble opening
.dwg's in the past.

Great Information Kevin,
I had no knowledge of those forces. The only inverted spin I was ever in
scared me so much that I have avoided such spins assiduously ever since
The more I learn about the TC, the better I like the T&B!
Thanks for the input.
I have some old thoughts on this subject that I posted on another list
several years ago. Would you mind if I sent them to you for your comment?
Happy Skies,

Hmmmm . . . I have a recent version of PKZIP.
I wonder if there are any compatibility problems
for un-zipping with older releases. I've considered
making my .zip files self-extracting but this
makes them .exe files which many folks are understandably
concerned about.
Try going to this directory:
http://www.aeroelectric.com/PPS/ACAD_Symbols_Library
2DIODBLK.DWG is an old symbol originally saved under R14 AutoCAD which
I just opened and re-saved under 2000. The thing jumped from
5K to 25K bytes (ugh!).
The one just below . . . 30SPDTRY.DWG is still in AutoCAD R14.
I'd appreciate it if you'd see how your TCv7.0 handles these
two files.
The Unzip corruption is another issue. I'll poke around on
the 'net and see if we might have a compatibility problem between
releases of PkZip.
Thanks!
Bob . . .

Re corrupted file:
2nd time was the charm. TurboCAD v 7.0 downloaded all the .dwg drawings just fine.
Thanks Bob.
