Fabian is great to work with. The product is first rate and the service will leave
you wondering why others can't do as well. The prices are VERY fair.
Everything fit like a glove. Fabian worked with Stark on my behalf to ensure my
harnesses were set up correctly for my installation.
The 3-piece panel will greatly simplify future maintenance.
I included a drawing of my panel to show you what you get. He'll first send a
CAD of your prospective panel so you can evaluate and make necessary adjustments.
When satisfied, let him know and he'll laser cut it and ship it out. I had
him design and cut my panel then I did all the installation and wiring.
I can't say enough about Affordable Panels.

Hi Bob ...
Couldn't agree more with the idea of using a venturi's to drive a single
instrument. The idea of driving a vacuum driven horizon has pulled at
me for some time. The group of three info providing life savers ...
attitude, airspeed and altitude are all air driven and simple. The only
one needing vacuum could easily be driven with an 8" venturi. The
venturi does require high velocity air over and through it to pull the
vacuum. My son and I were experimenting yesterday with a venturi 6"
long X 2" diameter. It will drive a turn needle (as it's designed to
do) but a horizon needs more beef to sustain it. I like the idea of
putting the venturi in the cowl exit air and I will try that with a
couple other venturi's. I also will create a gill type venturi which
could be placed on the side of the fuselage, right beside the inst panel
so the vacuum could be within about a foot of the horizon. When I have
the mods completed on my RV4 (before Spring) it will be used for this
test bed. The venturi is but one of these test items. Has anyone on
the list messed with a gill type venturi? My fondest hope would be to
create something made similar a NACA vent that could simply be
bonded/riveted onto the sheet metal and plug in a vacuum line. Done!
It's probably more involved than just that but it's the essence of the
thought.
You have to admit Bob, one peek at a vacuum horizon is worth 20 peeks at
a T&B ... : )

Good Afternoon Steve,
What I don't understand is why more folks don't use venturi's. They
work well, are cheap and are very reliable. If they are mounted on the
belly in the path of the airflow from the engine, they even have
reasonable protection from ice.
Many airplanes flew in heavy IFR weather for many years using nothing
but a venturi to power all of the instruments. What gave venturi's a bad
name was when foolish people started to mount them on the side of the
fuselage instead in the airstream behind the engine. I have a small
venturi powering a single T&B. If all else fails, I can easily control
the airplane with just that one T&B. If I have any altitude information
at all it is easy. Add a handheld GPS and I have more than the fanciest
airplanes had in the thirties.
One point though. Partial panel can be done with a turn coordinator,
but I much prefer the classic T&B. It is about the most reliable
mechanical instrument we have ever had. Some day, I am sure there will
be a solid state turn indicator that will replace the T&B. However,
until that time. Get a T&B, power it with a small venturi and spend a
thousand bucks on dual training getting thoroughly familiar with using
the T&B to control the airplane.
Happy Skies,
Old Bob

I don't know about you guys, but if I were building an experimental
and had no Type Certificate I had to abide by, I would be spending my
time figuring out how to build a bullet proof electrical system and
getting rid of anything that had the word Vacuum in it. It's an old,
archaic technology that, at the present date, serves ONLY to make
gyros cheaper. The vacuum pumps are less reliable or long-lived than
an alternator, and you're basically building a parallel power system
for gyros that adds weight and complexity, hoses, filters, etc, and
so on. If you've got redundant electrical, and you are now worrying
about a backup vacuum system, you're basically building QUADRUPLE
parallel systems to power gyros. That's insane to me.
Build redundancy into the electrical system, use solid state gyros,
eschew vacuum. Or was that "escrew"?

"Ratings" on switching contacts are to be considered with
a grain of salt . . . or sand. The probability of satisfactory
service life is only loosely related to "ratings".
The ratings are based on numbers of times a contact can
SWITCH certain kinds of loads . . . interestingly enough,
starter motors on engines are almost NEVER included in
the suite of standard loads for the establishment of
ratings.
For example, the el-cheeso battery contactors used on
tens of thousands of GA aircraft are RATED at 70A, yet
we've routinely cranked engines through these devices
with draws of 200-300 amps for decades. Given the enduring
presence of these critters in the marketplace, one must
deduce that users are seeing a satisfactory service life.
I.e., good value for the investment.
The thing that's hard on devices that switch starters is
not the average running current. The switch-killer
is the locked-rotor or inrush current that flows in the
milliseconds that the motor is accelerating up from
zero velocity while at the same time, contacts on the
switch are making MULTIPLE closures. See:
http://www.aeroelectric.com/Pictures/Curves/switch_transition.jpg
These are switches and not contactors but the effects
are similar for all such devices. In a millisecond to
a millisecond and a half, these switches close, open
and re-close many times.
This is why we SWITCH starter loads with STARTER CONTACTORS.
These have exceedingly thin and light contacts compared
to continuous duty contactors . . . these contacts are
driven together with much greater force so as to minimize
the bouncing and contact resistance. See:
http://www.aeroelectric.com/Pictures/Contactors/S702-1b.jpg
Another consideration for service life is total operations
per flight hour extrapolated out to total operations per
year. In the average GA aircraft, any switch or contactor
is hard pressed to see more than a few hundred operations
per year . . . a device that is RATED in the tens of thousands
of operations at RATED loads that may not be representative
of what the switch really sees in the airplane.
It's easy to see that many components might deliver satisfactory
service life in terms of chronological age in the airplane
in spite of being "overloaded" with respect to catalog ratings.
Keep in mind too that connections, and contacts for switching
devices ADD TO THE TOTAL loop resistance and may DOUBLE the
total loop resistance when compared wire resistance alone.
These are some of the reasons why it's not terribly useful
to agonize over the resistance of 2AWG vs 4AWG or the ratings
of any particular switch or contactor over another. The
ultimate test of your cranking system's ability to get the
engine moving is only measurable with some pretty sophisticated
test equipment. I have a DAS that will gather 2000 samples per
second so that instantaneous energy losses in the various
components and wire lengths can be quantified and decisions
made for optimization.
I'm not trying to discourage anyone from a quest to understand
the finer details of their ship's electrical system . . . but
know too that decisions made on rudimentary, single item
calculations and/or catalog data for components may not
stand on solid physics.

Good Afternoon Jerry,
I am not so sure I would agree. It is possible to have two artificial
horizons that are both active and that change attitude when you roll, but one
may
be accurate and the other not. You have to decide which is correct.
Attitude gyros do occasionally get the "leans".
In at least ninety-nine and forty-four one hundredths of a percent of the
times, if the T&B is wiggling, it is working.
And, if we are confused as to where up is, it is hard to believe an
instrument that does not agree with our senses. However, we don't have to agree
with
the T&B. If it says we are not turning , we will survive. It makes no
difference at all where we think up is. No turns, no problem!
Not only that, but even a cheap old airline pilot can afford one.
Happy Skies,

Subject: | Backup Electric Vacuum Pump |
Good Afternoon Dave,
I don't think doing whatever anyone wants to do to their personal
experimental aircraft is ever insane.
And, as a matter of fact, my 1978 Bonanza is now an all electric machine, so
I do agree that going all electric is a reasonable thing to do.
If someone does wish to add another back up to whatever is being used,
adding a single T&B powered by a single Venturi is about as light and cheap as
any
standby can be.
There is absolutely no requirement in the FARs that any of our older
airplanes have any redundancy at all. My first Bonanza had one vacuum pump, one
vacuum T&B, and one vacuum directional gyro. No attitude gyro and no back up for
the Vacuum. Perfectly legal for IFR at the time.
I added an electric T&B because I wanted a little more redundancy than was
installed in the airplane when I bought it. When the Attitude Gyro was added
to the list of instruments required for IFR light, I added a vacuum driven
attitude gyro. Still -- No redundancy required.
While some of the more recently approved airplanes do have redundancy built
into their certification limitations, we have no more requirement for
redundancy that do the homebuilders among us.
To each his own and all that stuff!

Good Evening Jerry,
I like the T&B.
If I had to choose between having only an artificial horizon or only a T&B ,
I would take the T&B every time.
The company took away our T&Bs back when I was flying the 720. I flew it
between 1968 and 1972 so imagine the T&B was eliminated in about 1970. I do
recall that the first time I got in turbulence after that was when I first missed
the T&B. I had not realized I had been using it to kill the Dutch roll, but
as soon as it started, my eyes fell to where the T&B had been located.
I realize that I also suffer from the disease of primacy. When I was getting
my instrument training, we were not allowed to use an Artificial Horizon or
a Directional Gyro. All the training and all the check rides were done
strictly on partial panel.
I managed to learn how to use those fancy gyros later in life, but I have
always reverted to the T&B when things started to get confusing. Since I tend
to get confused easily, I looked at the T&B a lot!
It is still the most reliable mechanical instrument available.
And it is light, cheap, and simple.
Happy Skies,
Old Bob

The least expensive, lightest, most useful and simplest
backup for any panel presentation of attitude
is the GPS aided wing leveler. If one is concerned
for reducing risks for failure of some piece of panel
equipment degrading the day's flight into an unhappy
event, the most risk free reversion mode is to let
a/p take over.

Just a bit more Jerry,
I am not ready to rely on having nothing but glass. In fact, I do not
believe I will buy a glass cockpit for several years, if ever. I am happy with
the
classic instruments and I will buy as cheap an MFD as I can get to play with
while I fly the airplane in reference to "traditional" information.
I would imagine that I will buy glass when it becomes cheaper than
traditional instrumentation. I DO believe that will eventually happen. Odds are

Good Evening Bob,
I do agree that having a wing leveler is a great idea.
I even like the way Mooney hooked it up so that we had to press on a button
any time we wanted to hand fly the airplane, but I do not believe you will
find ANY wing leveler that can be installed as cheaply as can a venturi powered
vacuum T&B.
An electrically powered T&B is even cheaper if you do not count the cost of
having an electrical system to power it.

I finally got around to daisy chaining my lighting strips. It works
well. I had a bit of trouble working out how to attach the wires to the
strips though.
I found a strip of PCB material with 6 lugs attached to it. They were
held in place by inserting them through the holes in the PCB material
and folding over 4 small ears. Just a matter of unfolding the ears and
removing them from the PCB.
A nail through the lighting strip and attaching the lugs worked well,
solder on your wire prior to attaching the lugs to the illumenesent
strip.

Subject: | Turbocad question |
Having recently picked up Turbocad, I find that I can open and edit the Z
drawings, but cannot get the program to keep the wires attached as various
components are moved around. If my old copy of Visio is able to create
attach points anywhere on the figure and do dynamic connector lines (wires),
I'm sure T-cad 10 should be able to, but I have yet to discover how to
enable it. Any help appreciated.

Tom,
Unfortunately TurboCAD does not have the "rubber banding" capability of
Visio and some of the electrical schematic CAD programs. There isn't
any way to drag a component and have all the lines (wires) stay attached
and be repositioned after dropping the component.

Hi Tom,
There is a page for *line connection* that contains the parameters that
are relevant when "connect lines" is activated.
It will allow you to set gap for connections, length for deletion and
angle at which line segments will be joined into polylines.
Then with the grid turned on points will stay in place if you use "g"
when closing a line.
"V" for vector or end of a line is a means of connecting a line end to
another. The selection arrow can be interchanged with a node pointer
that will
allow you to place line ends and points about a curve or polygon.
Dimensioning blocks provided for entering dimensional, positional and
orientation
data will also anchor line ends for you. Snaps are a means to secure
ends to a myriad of features and requires a bit of study to keep them
all straight, but they will
also do the trick. Sounds like you only need a little more time with
the program to learn its features.

Like in AutoCAD, it's called Stretch under the modify pulldown.

But, like all presentations under glass, it depends on the
integrity of a sensor/display/perception/reaction servo
loop of which includes a human having to work with the
reality of a rare but now present failure. N/B/AS is a
useful but exceedingly lousy alternative to stable gyros.
I wouldn't own an airplane without a gps aided wing
leveler just because it makes flying so much more
relaxed . . . whether the stuff under the glass is
working or not and a whole lot lower risk when it
is not.

Good Evening Bob,
May I take that to mean that you would want a GPS aided wing leveler in a
Stearman?, Piper Cub?, Luscombe?, Cessna 140? Cessna 172, Beech Musketeer?,
Beech Bonanza? North American AT-6? Twin Beech?
Where would you draw the line? All of the above? None of the above? Some of
the above?
I have never flown any airplane that had a GPS aided wing lever though I
have flown and owned plenty that did have wing levelers.
We all have to make individual decisions on what we feel meets our
individual level of risk, but requiring a GPS aided wing leveler is not real high
on
my list of necessities. Interesting that you think such a device is imperative.
Just goes to show, there is a wide range of desires among us all.

Sure, why not? The answer is simple for most owners
but for myself, I wouldn't own one of those airplanes
because I need to stand in line at too many windows
begging permission to make it better.
>Where would you draw the line? All of the above? None of the
>above? Some of the above?
You have just illuminated the reason that those airplanes
are all rotting away never to be replaced. The GPS
aided wing leveler is mechanically no more difficult to
install in one of those airplanes than in an RV. But
those who claim to know more about what's good for us
have become the mill-stones between which those airplanes
are slowly turning to dust.

Depends on what your design goals are. For most of the
the folks on this List, reducing cost of ownership is
a goal. Dependency on a T&B traded for dependency on
a GPS aided wing leveler offers a lower cost of ownership
over the lifetime of the airplane.
>Just goes to show, there is a wide range of desires among us all.
If the "desire" is to minimize the probability of an
unhappy ending to a piece of equipment failing, then
the design goals are pretty clear. I've watched the
conversations here on the List and elsewhere for
over a decade that vigorously debated the value of
this technique or piece of equipment over that . . .
But seldom did the conversation recommend reversion
modes that reduce, not increase pilot workload.
I'm dead-nuts serious about the admonition in my
signature tag . . . an exceedingly small number of pilots
accomplish daily practice for standard (much less reversion)
modes flight in IMC. I understand that you may be personally
comfortable . . . and perhaps world class in skills and
willingness to fly through clouds with the venerable tools
of yesteryear. I've done it too. But I cannot in good
conscience recommend that the neophyte builder embrace
these techniques today when there are better options that
are cheap as a percentage of the total cost of acquiring,
owning and operating an airplane.
In a cost-of-ownership accounting, the venturi-driven
T&B offered as a gift will be more expensive in $time$
expended than what's needed to install the modern alternative.
Further, the GPS aided wing leveler adds value to a
high percentage of every flight while the T&B is useful
for calibrating your rudder pressure on climb-out,
setting rudder trim, and being there to assist with the
management of a failure that you hope will never come but
demands a perpetual investment of $time$ to make sure
you are ready when it does.
Very few of us are professional pilots. Those of us
who are should be mindful of advice which presumes that
all listeners are interested in (or even capable of) achieving
levels of proficiency needed to avoid quantum jumps
in risk after certain failures. This isn't about a "wide
range of desires" but simple failure modes effects analysis
in a market place where the pilots come with a wide range
of capability and willingness to spend $time$ necessary
to level the risks if not lower them.
One of the reasons why I see an opportunity for OBAM aviation
to excel in accident reduction is because we can readily
take advantage of modernization opportunities for reducing
workload without begging anyone's permission.
When the GPS aided wing leveler is present, failure of the
primary display does not generate an immediate need
to revert to a whole new mode of flying. When one is
depending on primary attitude displays to stay upright,
then reversion to N/B/AS aviating at the same level of risk
demands and investment of $time$ for maintenance of
proficiency. The GPS aided wing leveler will hold track to
within a degree or so all day, every day and doesn't need a
bit of practice to stay "world class" at the task.
