Subject: | Securing Adel Clamps? |
--> AeroElectric-List message posted by: <rparigor@suffolk.lib.ny.us>
I am working on tunnel/undercarriage area of a Europa XS Monowheel. I
installed Adel clamps on Undercarriage Mounting Frame 1/2" and 3/4" to
help with routing of wires, cables and hoses.
This is a complicated tight area on airplane.
The problem is if I try not too hard, I can twist clamps to a undesirable
position, where it would be hard to reposition once the firewall is
installed. The clamps are of proper size, and the next size down will not
fit.
Any suggestions how to get the clamps a bit more stuck?
Thx.
Sincerely
Ron Parigoris

Hi Ron
I put a turn or two of self bonding silicone tape such as Spruce pn
09-30450 under the clamps in a few places.

Is anybody else seeing messages posted multiple times to the list?
Looking through the list mail this morning, I'm seeing two or three
copies of some messages that I've already seen twice or more.

I let Matt know about it yesterday. Looks like he already fixed it as I haven't
seen anything new since then.

Understand. Utility items like courtesy lights can
be fitted with on-limit timers. We have these on
some of our bizjets for baggage compartment lights.
More than one important trip was delayed or canceled
because of a light being left on and the battery was
completely flat at pre-flight.
Very light draws you mentioned are continuous,
necessary and generally tolerated if the airplane
is flown often enough. If stored for long periods
of time, disconnecting the battery or installing
a maintainer jack seems useful.
We'll have a programmable on-limit timer in the
new bevy of products coming to aeroelectric.com
Our first two new products are nearing the field
testing phase. I'll see if we can do the on-limit
timer as project #3.

--> AeroElectric-List message posted by: Jack Loflin <loflinj@comcast.net>
Hi all,
I have a Garmin GNS 480 (formerly CNX 80 of UPSAT) install kit I'm trying to
get rid of. It was wired by Stark Avionics (the famous 'John Stark') and is
ready to be installed in your panel during construction. The 'black box' can
be slid into the tray at a later date when needed and money is available.
Make offer, anything considered! Please respond directly.

Might as well add my two cents as long as the rest of the Rochester area
has chimed in! <G>
I was getting them for awhile this weekend as well...but it looks like
it's back to normal now...guess Matt figured it out.

I'll bet you can find schematics for those in Popular Electronics going

Understand. Utility items like courtesy lights can
be fitted with on-limit timers. We have these on
some of our bizjets for baggage compartment lights.
More than one important trip was delayed or canceled
because of a light being left on and the battery was
completely flat at pre-flight.
Very light draws you mentioned are continuous,
necessary and generally tolerated if the airplane
is flown often enough. If stored for long periods
of time, disconnecting the battery or installing
a maintainer jack seems useful.
We'll have a programmable on-limit timer in the
new bevy of products coming to aeroelectric.com
Our first two new products are nearing the field
testing phase. I'll see if we can do the on-limit
timer as project #3.

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.

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 . . .

Subject: | Blind encoder Display |
--> AeroElectric-List message posted by: Richard Hughes <richardhughes260@yahoo.com>
My ACK encoder was out of adjustment by 400 plus feet.
Yesterday morning, I soldered tohgether a board with a
resistor and 9 diodes. If you have the time to wait
for shipping get the RST item in the link.
(http://www.rst-engr.com/rst/catalog/altitude_encoder_and_elt.html)
It displays the data lines coming out of the encoder
A1 A2 A4 Bi B2 B4 C1 C2 C4.
This allowed my partner and myself to remove the
encoder and altimiter, using a hand pump calibrate the
encoder on the dining room table instead of in the
cold.
Here is a 100 ft Gray code table if anyone is
interested http://www.airsport-corp.com/modecascii.txt
I want to use a Basic Stamp II (I have a few) to read
the lines and display them on a serial LCD. The
question is the interface.
When a line has a zero value it is at 12 volts, when a
line has a one value it goes to ground. Could I just
put diodes on the lines and check each pin for when it
goes to ground? The Stamp is a TTL device. Do I need a
seperate chip to detect the voltage that can handle up
to 12 volts?
The goal is to give human readable altitudes on an lcd
display while in flight and providing mode C to the
transponder.

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,

--> AeroElectric-List message posted by: nuckollsr@cox.net
--> AeroElectric-List message posted by: "Robert L. Nuckolls, III" <nuckollsr@cox.net>
99+ percent of alternator failures is to simply stop
producing for whatever reason . . . including ov trip.
A major fraction of what's left will be cause for manual
shutown . . . voltage unstable? Whatever. It is very unlikely
that any alternator failure will take out the b-lead protection.
It's axiomatic that many problems get worse when the pilot
starts messing with things in some attempt to "get all the
goodies back up and running."
The advantage of a fully dual system is that you spread
your backup systems around. One on main bus, one on aux
bus. The best thing to do when something goes T.U. on one
bus is to simply shut that one down. Go into an endurance
mode until comfortable arrival is assured. Battery on the
cold bus is held in reserve. Battery on working bus is
being supported by normal alternator operations.
When and if anything on the 'cold' bus becomes useful
or necessary in the final phase of flight. Close battery
contactor first and watch for normal battery-only
bus levels. Close crossfeed contactor second while observing both
bus voltages now show normal operational levels. Then
finish the flight.
If any voltages appear out of whack after operation of
a switch, re-open the switch immediately and finish the
flight on one bus . . . but don't do this experiment until
you have the airport in sight.
I think it's useful to think of the various system options
as tools for comfortable termination of flight by insuring
availability of minimum equipment . . . the exercises that
pilots go through to perform in-flight diagnostics and/or
get some suite of equipment up running doesn't
necessarily improve outcome is certainly a distraction
and perhaps hazardous.
Only the more complex aircraft can justify Z-14. While
complexity brings capability and convenience, it also
brings workload. If you're vfr in the clear, then perhaps
a total failure is no big deal. When you are depending on at
least the most useful of things to be working then you're
probably IFR and busy with pilot-things to do. The last
thing you want to do is troubleshoot especially when there
is risk of making a situation worse.

Besides us Linux guys don't appreciate .exe files at all. I checked a
few of the DWG files from the first link you posted and they open with
VariCAD after I changed all the extensions to lower case.

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.

I don't think there was ever a consensus for a "golden"
battery maintainer. I've tested several Battery Tender
and Schumacher (Wall Mart and others) products and found
that they meet their advertising sales literature and
do indeed offer battery charging and maintaining functions
superior to similar products offered a few years ago. I
have some samples from Soneil which I tested several
months ago. I couldn't get them to do the advertised
"desulfating pulse-charge". I've had some limited
conversation with them since and had planned to visit
their facility as a side trip on our visit to Canada
for a weekend seminar late last year. The visit didn't
work out and further examination of Soneil's products
are on the back burner for the moment.
In the mean time, go to Wall Mart or perhaps Ebay
(Item number: 4601687546) and get a perfectly
adequate charger/maintainer for little more than
pocket change.

Subject: | Blind encoder Display |
--> AeroElectric-List message posted by: "Craig Payne" <craig@craigandjean.com>
My transponder will do this (Garmin GTX 327). Is there any display on yours?
Also some encoders also spit out RS232. That might be easier to connect to
the PIC.

Subject: AeroElectric-List: Blind encoder Display
--> AeroElectric-List message posted by: Richard Hughes
--> <richardhughes260@yahoo.com>
My ACK encoder was out of adjustment by 400 plus feet.
Yesterday morning, I soldered tohgether a board with a resistor and 9
diodes. If you have the time to wait for shipping get the RST item in the
link.
(http://www.rst-engr.com/rst/catalog/altitude_encoder_and_elt.html)
It displays the data lines coming out of the encoder
A1 A2 A4 Bi B2 B4 C1 C2 C4.
This allowed my partner and myself to remove the encoder and altimiter,
using a hand pump calibrate the encoder on the dining room table instead of
in the cold.
Here is a 100 ft Gray code table if anyone is interested
http://www.airsport-corp.com/modecascii.txt
I want to use a Basic Stamp II (I have a few) to read the lines and display
them on a serial LCD. The question is the interface.
When a line has a zero value it is at 12 volts, when a line has a one value
it goes to ground. Could I just put diodes on the lines and check each pin
for when it goes to ground? The Stamp is a TTL device. Do I need a seperate
chip to detect the voltage that can handle up to 12 volts?
The goal is to give human readable altitudes on an lcd display while in
flight and providing mode C to the transponder.

Oops...guess I was too early...looks like it's doing it again!
Seems that every email that is a duplicate has an administrators ID
number or two on it...like this one:
AdmID:C54FF9E1511873D4B582657F68925039
And, it appears that they are the same ones that were repeated this last weekend.
None of the newer messages seem to be included.
If that's any help...

Tim,
Thanks for the files. I will have to strip my sub-panels and repaint
with smooth paint though. Final result will be worth it.

My drawings were done using Visio. I just used Arial 10 and 12 PT I
think for most things. I would be happy to share my original
files with you if you'd like. I did them in visio, but the
company that did my screens couldn't read a visio file, so
I think I either sent them a word doc with the drawing in it, or
I sent them a large .jpg. I have any of them available for
your viewing if you wish. It might save you some time
if you had visio so you didn't have to recreate.

I don't think there was ever a consensus for a "golden"
battery maintainer. I've tested several Battery Tender
and Schumacher (Wall Mart and others) products and found
that they meet their advertising sales literature and
do indeed offer battery charging and maintaining functions
superior to similar products offered a few years ago. I
have some samples from Soneil which I tested several
months ago. I couldn't get them to do the advertised
"desulfating pulse-charge". I've had some limited
conversation with them since and had planned to visit
their facility as a side trip on our visit to Canada
for a weekend seminar late last year. The visit didn't
work out and further examination of Soneil's products
are on the back burner for the moment.
In the mean time, go to Wall Mart or perhaps Ebay
(Item number: 4601687546) and get a perfectly
adequate charger/maintainer for little more than
pocket change.

My transponder will do this (Garmin GTX 327). Is there any display on yours?
Also some encoders also spit out RS232. That might be easier to connect to
the PIC.

My ACK encoder was out of adjustment by 400 plus feet.
Yesterday morning, I soldered tohgether a board with a resistor and 9
diodes. If you have the time to wait for shipping get the RST item in the
link.
(http://www.rst-engr.com/rst/catalog/altitude_encoder_and_elt.html)
It displays the data lines coming out of the encoder
A1 A2 A4 Bi B2 B4 C1 C2 C4.
This allowed my partner and myself to remove the encoder and altimiter,
using a hand pump calibrate the encoder on the dining room table instead of
in the cold.
Here is a 100 ft Gray code table if anyone is interested
http://www.airsport-corp.com/modecascii.txt
I want to use a Basic Stamp II (I have a few) to read the lines and display
them on a serial LCD. The question is the interface.
When a line has a zero value it is at 12 volts, when a line has a one value
it goes to ground. Could I just put diodes on the lines and check each pin
for when it goes to ground? The Stamp is a TTL device. Do I need a seperate
chip to detect the voltage that can handle up to 12 volts?
The goal is to give human readable altitudes on an lcd display while in
flight and providing mode C to the transponder.

Besides us Linux guys don't appreciate .exe files at all. I checked a
few of the DWG files from the first link you posted and they open with
VariCAD after I changed all the extensions to lower case.

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,

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.

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

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.

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!

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.

99+ percent of alternator failures is to simply stop
producing for whatever reason . . . including ov trip.
A major fraction of what's left will be cause for manual
shutown . . . voltage unstable? Whatever. It is very unlikely
that any alternator failure will take out the b-lead protection.
It's axiomatic that many problems get worse when the pilot
starts messing with things in some attempt to "get all the
goodies back up and running."
The advantage of a fully dual system is that you spread
your backup systems around. One on main bus, one on aux
bus. The best thing to do when something goes T.U. on one
bus is to simply shut that one down. Go into an endurance
mode until comfortable arrival is assured. Battery on the
cold bus is held in reserve. Battery on working bus is
being supported by normal alternator operations.
When and if anything on the 'cold' bus becomes useful
or necessary in the final phase of flight. Close battery
contactor first and watch for normal battery-only
bus levels. Close crossfeed contactor second while observing both
bus voltages now show normal operational levels. Then
finish the flight.
If any voltages appear out of whack after operation of
a switch, re-open the switch immediately and finish the
flight on one bus . . . but don't do this experiment until
you have the airport in sight.
I think it's useful to think of the various system options
as tools for comfortable termination of flight by insuring
availability of minimum equipment . . . the exercises that
pilots go through to perform in-flight diagnostics and/or
get some suite of equipment up running doesn't
necessarily improve outcome is certainly a distraction
and perhaps hazardous.
Only the more complex aircraft can justify Z-14. While
complexity brings capability and convenience, it also
brings workload. If you're vfr in the clear, then perhaps
a total failure is no big deal. When you are depending on at
least the most useful of things to be working then you're
probably IFR and busy with pilot-things to do. The last
thing you want to do is troubleshoot especially when there
is risk of making a situation worse.

Here's an RS-232 receiver (level shifter) that'll do what you're looking
for:

However, with a Google or two I bet you'll uncover a few robotics folks

I'll bet you can find schematics for those in Popular Electronics going

Understand. Utility items like courtesy lights can
be fitted with on-limit timers. We have these on
some of our bizjets for baggage compartment lights.
More than one important trip was delayed or canceled
because of a light being left on and the battery was
completely flat at pre-flight.
Very light draws you mentioned are continuous,
necessary and generally tolerated if the airplane
is flown often enough. If stored for long periods
of time, disconnecting the battery or installing
a maintainer jack seems useful.
We'll have a programmable on-limit timer in the
new bevy of products coming to aeroelectric.com
Our first two new products are nearing the field
testing phase. I'll see if we can do the on-limit
timer as project #3.

Thanks for the files. I will have to strip my sub-panels and repaint

My drawings were done using Visio. I just used Arial 10 and 12 PT I
think for most things. I would be happy to share my original
files with you if you'd like. I did them in visio, but the
company that did my screens couldn't read a visio file, so
I think I either sent them a word doc with the drawing in it, or
I sent them a large .jpg. I have any of them available for
your viewing if you wish. It might save you some time
if you had visio so you didn't have to recreate.

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?

Actually, the roll and yaw are in opposite directions in an inverted

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.

Subject: | ELT Antenna Length |
--> AeroElectric-List message posted by: "Tinne maha" <tinnemaha@hotmail.com>
I know this is a dumb question, but I think it would be dummer for me not to
ask: In order for it to fit in what I believe to be the best location, I
need to shorten my ELT antenna from 21 inches to 19-3/8 inches. Will that
adversely affect performance? Another location will be very difficult. Can
anyone suggest another solution?
Thanks,

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!

Besides us Linux guys don't appreciate .exe files at all. I checked a
few of the DWG files from the first link you posted and they open with
VariCAD after I changed all the extensions to lower case.

I don't think there was ever a consensus for a "golden"
battery maintainer. I've tested several Battery Tender
and Schumacher (Wall Mart and others) products and found
that they meet their advertising sales literature and
do indeed offer battery charging and maintaining functions
superior to similar products offered a few years ago. I
have some samples from Soneil which I tested several
months ago. I couldn't get them to do the advertised
"desulfating pulse-charge". I've had some limited
conversation with them since and had planned to visit
their facility as a side trip on our visit to Canada
for a weekend seminar late last year. The visit didn't
work out and further examination of Soneil's products
are on the back burner for the moment.
In the mean time, go to Wall Mart or perhaps Ebay
(Item number: 4601687546) and get a perfectly
adequate charger/maintainer for little more than
pocket change.

--> AeroElectric-List message posted by: Richard Hughes

My ACK encoder was out of adjustment by 400 plus feet.
Yesterday morning, I soldered tohgether a board with a resistor and 9
diodes. If you have the time to wait for shipping get the RST item in the
link.
(http://www.rst-engr.com/rst/catalog/altitude_encoder_and_elt.html)
It displays the data lines coming out of the encoder
A1 A2 A4 Bi B2 B4 C1 C2 C4.
This allowed my partner and myself to remove the encoder and altimiter,
using a hand pump calibrate the encoder on the dining room table instead of
in the cold.
Here is a 100 ft Gray code table if anyone is interested
http://www.airsport-corp.com/modecascii.txt
I want to use a Basic Stamp II (I have a few) to read the lines and display
them on a serial LCD. The question is the interface.
When a line has a zero value it is at 12 volts, when a line has a one value
it goes to ground. Could I just put diodes on the lines and check each pin
for when it goes to ground? The Stamp is a TTL device. Do I need a seperate
chip to detect the voltage that can handle up to 12 volts?
The goal is to give human readable altitudes on an lcd display while in
flight and providing mode C to the transponder.

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.

99+ percent of alternator failures is to simply stop
producing for whatever reason . . . including ov trip.
A major fraction of what's left will be cause for manual
shutown . . . voltage unstable? Whatever. It is very unlikely
that any alternator failure will take out the b-lead protection.
It's axiomatic that many problems get worse when the pilot
starts messing with things in some attempt to "get all the
goodies back up and running."
The advantage of a fully dual system is that you spread
your backup systems around. One on main bus, one on aux
bus. The best thing to do when something goes T.U. on one
bus is to simply shut that one down. Go into an endurance
mode until comfortable arrival is assured. Battery on the
cold bus is held in reserve. Battery on working bus is
being supported by normal alternator operations.
When and if anything on the 'cold' bus becomes useful
or necessary in the final phase of flight. Close battery
contactor first and watch for normal battery-only
bus levels. Close crossfeed contactor second while observing both
bus voltages now show normal operational levels. Then
finish the flight.
If any voltages appear out of whack after operation of
a switch, re-open the switch immediately and finish the
flight on one bus . . . but don't do this experiment until
you have the airport in sight.
I think it's useful to think of the various system options
as tools for comfortable termination of flight by insuring
availability of minimum equipment . . . the exercises that
pilots go through to perform in-flight diagnostics and/or
get some suite of equipment up running doesn't
necessarily improve outcome is certainly a distraction
and perhaps hazardous.
Only the more complex aircraft can justify Z-14. While
complexity brings capability and convenience, it also
brings workload. If you're vfr in the clear, then perhaps
a total failure is no big deal. When you are depending on at
least the most useful of things to be working then you're
probably IFR and busy with pilot-things to do. The last
thing you want to do is troubleshoot especially when there
is risk of making a situation worse.

Might as well add my two cents as long as the rest of the Rochester area

I was getting them for awhile this weekend as well...but it looks like
it's back to normal now...guess Matt figured it out.

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.

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.

Here's an RS-232 receiver (level shifter) that'll do what you're looking
for:

However, with a Google or two I bet you'll uncover a few robotics folks that

The ACK encoder I have does Gray code only.
The King KT76A does not display altitude. :(
I was thinking about opto isolators although the Texas
Instruments 75189 looks good, I would need 3 to do all
9 lines, but I would need 9 opto isolators.

AeroElectric Lister,
Looks like the following email address on the AeroElectric-List was the culprit:
yamokosk@lakemichigancollege.edu
Interestingly, this is a community college in Lake Michigan.
They were sending duplicates of messages back to the list with all the original
headers, so it looked like it kept coming from the original people.
I'm suspecting this might be some sort of automated message archiver that is misconfigured.
I've unsubscribed the address from the List and sent them an email.
Things should be back to normal now!

Rich,
I am not familiar with the ACK unit.
Is it adjustable, and is the adjustment linear over the total altitude range
once you have made the new calibration?

Understand. Utility items like courtesy lights can
be fitted with on-limit timers. We have these on
some of our bizjets for baggage compartment lights.
More than one important trip was delayed or canceled
because of a light being left on and the battery was
completely flat at pre-flight.
Very light draws you mentioned are continuous,
necessary and generally tolerated if the airplane
is flown often enough. If stored for long periods
of time, disconnecting the battery or installing
a maintainer jack seems useful.
We'll have a programmable on-limit timer in the
new bevy of products coming to aeroelectric.com
Our first two new products are nearing the field
testing phase. I'll see if we can do the on-limit
timer as project #3.

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.

99+ percent of alternator failures is to simply stop
producing for whatever reason . . . including ov trip.
A major fraction of what's left will be cause for manual
shutown . . . voltage unstable? Whatever. It is very unlikely
that any alternator failure will take out the b-lead protection.
It's axiomatic that many problems get worse when the pilot
starts messing with things in some attempt to "get all the
goodies back up and running."
The advantage of a fully dual system is that you spread
your backup systems around. One on main bus, one on aux
bus. The best thing to do when something goes T.U. on one
bus is to simply shut that one down. Go into an endurance
mode until comfortable arrival is assured. Battery on the
cold bus is held in reserve. Battery on working bus is
being supported by normal alternator operations.
When and if anything on the 'cold' bus becomes useful
or necessary in the final phase of flight. Close battery
contactor first and watch for normal battery-only
bus levels. Close crossfeed contactor second while observing both
bus voltages now show normal operational levels. Then
finish the flight.
If any voltages appear out of whack after operation of
a switch, re-open the switch immediately and finish the
flight on one bus . . . but don't do this experiment until
you have the airport in sight.
I think it's useful to think of the various system options
as tools for comfortable termination of flight by insuring
availability of minimum equipment . . . the exercises that
pilots go through to perform in-flight diagnostics and/or
get some suite of equipment up running doesn't
necessarily improve outcome is certainly a distraction
and perhaps hazardous.
Only the more complex aircraft can justify Z-14. While
complexity brings capability and convenience, it also
brings workload. If you're vfr in the clear, then perhaps
a total failure is no big deal. When you are depending on at
least the most useful of things to be working then you're
probably IFR and busy with pilot-things to do. The last
thing you want to do is troubleshoot especially when there
is risk of making a situation worse.

Grant,
If you were able to add a "loading" coil to the antenna correctly, this
would allow you to shorten the current antenna. You would need a guru type
friend that knew antennas to accomplish this for you. However, I would bet
that a search of the web via Google would find a manufacturer that makes the
"loaded" antennas for the frequency that you need.

FWIW...
We bought a nice RV6a with an EXBUS in it, and has worked fine for 400+
hours. The builder had to add a few switches though, to make things work.
However, everything Bob says is true about it IMO, and I am wiring my "Garage
Queen"
-6a per Z-11. This has already given me more flexibility with 2x10 fuse
blocks, switches that I can swap around at will, and many more benefits. The
EXBUS pretty much locks you in for architecture, may be o.k. for those who don't
care to deal at all with electrons. For me, it has been the most enjoyable
part of the project so far. I do believe the Subaru conversions, at least
Eggenfellner, require it, don't they?

Besides us Linux guys don't appreciate .exe files at all. I checked a
few of the DWG files from the first link you posted and they open with
VariCAD after I changed all the extensions to lower case.

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!

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.

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.

Per my previous response, on the 2nd try, the symbols library file unzipped just
fine.
I dragged both symbols, 2DIOBLK.DWG and 30SPDTRY.DWG, into a drawing and they manipulate
fine with TurboCAD v 7.0 .

Tim,
Thanks for the files. I will have to strip my sub-panels and repaint
with smooth paint though. Final result will be worth it.
Thanks,

My drawings were done using Visio. I just used Arial 10 and 12 PT I
think for most things. I would be happy to share my original
files with you if you'd like. I did them in visio, but the
company that did my screens couldn't read a visio file, so
I think I either sent them a word doc with the drawing in it, or
I sent them a large .jpg. I have any of them available for
your viewing if you wish. It might save you some time
if you had visio so you didn't have to recreate.

I was getting them for awhile this weekend as well...but it looks like
it's back to normal now...guess Matt figured it out.

WOW....the duplicate messages are starting to breed like rats.
I am wondering if there is not a "loop" going on in Matt's system or the
message is going to someone on the List that has a virus and gets sent back
immediately to the server for another loop.......

Here's an RS-232 receiver (level shifter) that'll do what you're looking
for:

However, with a Google or two I bet you'll uncover a few robotics folks
that have already generated a plug-n-play solution for BS2 serial comm.

the capacitors are ceramic disk and the resistors are 1/4 watt. Any help will
be greatly appreciated.

He recommends it, but it is not a requirement. I'm not using the

Group:
I have a quick question regarding how the mags are wired to toggle switches as
illustrated in drawing Z-11.
As wired in this schematic, if you place the right mag to "on" and then engage
the starter via the left mag/start switch, does this ground out both mags so that
you can turn the engine over with the ignition essentially off?
Thanks in advance

There are a couple of ways to approach this. Perhaps the simplest is to
clamp the inputs to ground and +5 using diodes and provide a
current-limiting resistor like this:
+5
|
---
/ \
---
|
encoder output >--/\/\/\----+-------> TTL input
R1 |
---
/ \
---
|
gnd
R1 needs to be selected to limit the current. 10K should be just fine
and will limit current to under 1mA. This will clamp the input to within
one diode drop of ground or +5VDC.
OTOH, isn't the STAMP a CMOS product? If so, it might not care if you
use +12 and ground as inputs. It probably has protective diodes inside
already so you would just need the current-limiting resistor. Still, the
diode clamp approach is safe and will work.

I did some tests on a bizjet installation where we substituted
a "rubber-duck" of a VHF-Comm hand-held for a full sized 21 inch
antenna. Differences in gain and pattern were barely discernable.

Subject: | E-Bus Avionics Switch ? |
--> AeroElectric-List message posted by: "Bill Schlatterer" <billschlatterer@sbcglobal.net>
Just thinking? On any of the Endurance Bus drawings. Other than the "don't
really need it" discussion and parts count issue, what would the downsides
be of adding a S704 contactor between the D25 and E-Bus so that you
effectively used the whole E-bus as an Avionics bus. This would assume that
the E-bus load can be easily carried by the S704 which I think is rated at
20 amps and has low continuous draw. It would actually save several
switches for EFIS systems like the GRT which are not internally switched.
Comments appreciated.

An ELT is an insurance policy you hope to not have to use. Changing the
length by 8% will cause the transmitter to no longer reach its maximum
distance. Maybe instead of 40 mile range you only get 35. If by
shortening it, the SWR goes up to the point that the automatic overload
circuitry trips in the ELT and shuts off the transmitter, that wouldn't be
good either. Ask the ELT manufacturer about that. If you're going to be
doing a lot of flying over the Amazon, you might reconsider.
A better question might be what is limiting the length to 19 3/8? Is it a
metal panel? Proximity to metal would be an even more serious problem than
an 8% shorter antenna. Can you bend the antenna and keep its length?

Subject: | Re: mag switches |
--> AeroElectric-List message posted by: "Matt Prather" <mprather@spro.net>
Hello Jeff,
The way I interpret the drawing is that when the right mag is "on", the
starter circuit is disabled. In other words, when the right mag is on
(disconnecting 2 from 3), continuity between terminals 5 and 6 is broken,
which disables the starter circuit.
The drawing shows the right mag switch in the OFF-START position.
With the switch selected as drawn, the right mag is grounded out
(disabled) via continuity between terminals 2 and 3.
The drawing shows the left mag grounded out (disabled) via terminals 2 and 3.
The drawing shows the starter circuit is disabled because terminals 4 and
5 on the left mag aren't connected.
As drawn, if the left mag switch is moved, the left mag is disabled. If
it is moved to its full opposite position, the left mag is enabled (no
continuity between 2 and 3), and the starter is enabled (continuity
between 4 and 5).
I hope that helps..
Regards,
Matt-

Subject: | All New BBS Interface For Matronics List Forums! |
--> AeroElectric-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
I'm very proud to announce a completely new BBS interface is now available for
all of the Email Lists at Matronics! This is a full-featured system that allows
for viewing, posting, attachments, polls - the works.
But the best part is that it is *completely* integrated with all of the existing
email tools currently available at Matronics! What this means at the most basic
level is that, if you post a message to List from Email in the traditional
way, it will show up on the BBS system *and* get distributed to everyone currently
subscribed to the Email List. By the same token, if you are on the BBS
and post a message to a given List-Forum, the message will not only show up on
the BBS, but also be distributed to everyone on the Email List!!
It is really a very nice implementation and I am very pleased with its operation.
All of the tools you have come to know and love such as the List Search Engine
and List Browse and Download will still be available and contain all of the
latest posts. Think of the new BBS interface as just another method of accessing
the all of the Lists.
You can use the BBS to view all of the latest posts without having to do anything
except use your browser to surf over to the site. You can view and look at
all of the various List's posts. If you want to post a new message or reply
to an existing message from the BBS, you will have to Register on the BBS. This
is a *very* simple process and will only take a couple of minutes. There is
a small icon in the upper righthand side of the main BBS page labeled "Register"
to get you started.
I strongly recommend that you use the exact *same* email address you are subscribed
to the Email Lists with when registering on the BBS. Also, while not an
absolute requirement, I would really appreciate it if people would use their full
name when choosing their Username on the BBS (for example "Matt Dralle").
This just makes it easier for everyone to know who's posting. Also, I have enabled
the ability to upload a small user picture with your profile called an
"avatar". Please use a *real* picture of yourself *with* your cloths on! Thank
you! Maximum size of the bitmap is 120x120.
You can either be subscribed to the BBS, or any number of Email Lists, or both.
Registering on the BBS will allow you to email directly to all of the various
Lists. However, to receive direct List Email, you will need to be *subscribed*
to the various Lists as you have in the past. No changes here in operation.
I have added numerous links on the BBS pointing to the Email List subscription
page.
I've had the BBS connected to the Lists for about a week now, so its already loaded
up with a fair number of messages. You can post photos and other documents
directly to the BBS and links to them will appear in the List Email distributions.
Also, when any messages posted to the BBS are viewed in the List Email
distribution, there will be a URL link at the bottom of the message pointing
back to the BBS.
And here's what you've been waiting for -- the main URL for the new Matronics Email
List BBS is:
http://forums.matronics.com
Please surf on over, Register, and have a great time! I think this will be the
dawn of a whole new era for the Lists at Matronics!
Best regards,
Matt Dralle

Is this antenna "inside" or does it mount out in the breeze?

Thanks Matt.
I guess what I really want to know is how do you turn an engine over as
wired in Z11 without the mags hot?

Greetings,
This month is wiring month for my Lancair Legacy. My preliminary load analysis
for each electrical bus is presented for review and comment. Composite airplane,
engine in front, 75 amp main alternator, SD-8 aux alternator, single battery,
Z-13/8 all electric on a budget with overweight E-Bus. Chelton Sport glass
cockpit with backups for airspeed, altimeter, and electric attitude indicator
(TruTrak ADI). IFR and night flights anticipated. The "Typ Amps" represents
the typical continuous current in cruise flight.
I'm curious if anyone has comments regarding which components are on each bus.

Without adding jumpers, or more switches, it won't happen.. In order to
engage the starter, the left mag switch will have terminals 1 and 2
connected, which will enable the left magneto (because terminal 1 isn't
connected to anything). For diagnostic purposes, you could connect
terminal 1 to ground. Then the left mag would be disabled.

Greetings,
Please disregard my previous posting, "Load Analysis," because an apparent formatting
problem makes it unreadable. I'll post a readable version tomorrow.
