Subject: | Calibrating fuel qty gauges |
How do you calibrate fuel qty using a 10 - 75 ohm sender unit with a 0 -90 ohm
fuel gauge? in other words what's the best why to get the gauges to read accurately
near empty, which is more important then FULL. Thanks

Unfortunately the situation is more annoying than that. There is usually
difficulty talking with the tower. Sometimes it is bad enough that clearance
has been denied. This is very inconvenient since it is the home base of this
aircraft :-(

There is little else electrical in the aircraft. We tried turning off the
transponder. There are no lights, fuel pump or even turn coordinator.
Switching off the alternator should also power off the regulator.

The noise and the receive audio continue identically, not even a click as
the antenna is connected and disconnected. This baffles me.
The noise persists away from the airport. When calling up the tower from
10 miles out it is difficult to understand the controller. Sometimes the
controller also has trouble understanding the transmissions from the aircraft.
Changing the direction of the aircraft sometimes helps.

The radio is 25KHz spacing, according to the little brochure that suffices
as the operation manual.

Ground is 118.40, Tower is 120.10 and the ATIS is 125.67.
I haven't tried anything at the top end, but hopefully will get a chance
to do so this week when I check the antenna cables and antenna by patching
in a handheld.

Yeah . . . I got my first airplane ride off that
airport when I was about 4 or 5 years old. Dad
got his ticket in a J-3 on the GI bill.
They're making noises about a new airport for
M.L. seems like there's some bundle of our grandchildren's
money that's being handed out for some form of
stimulus or another. Problem with current location
is outcropping of gypsum laden dirt off north end
of the runway that disqualifies it for an instrument
approach. They're talking about a new facility
somewhere southeast.
Emacs!
The town of Pixley blew away in a tornado about 1940 or so and
was never rebuilt but it was never removed from the maps. Our
house is the little red dot in the upper left corner. Maybe
we can turn the old airport into an ultralight facility.

Subject: AeroElectric-List: Re: Radio Noise
Jeff,
I believe you said the radio was bench tested and found to be operational.
If this is the case, then from your description of the problem, it appears
that it is either the (1) antenna and/or cable, (2) power/ground wiring, or
(3) mike/speaker wiring.
If it is the antenna, you should be able to determine this by unpluging from
the radio and hook up to a portable radio for test.
If power/ground, this can be checked with a meter. (check the wiring
diagram to make sure that there are connections to all power and ground
points. Some devices have multiple power and ground wires)
If it is mike/speaker connection, this can be caused by using an incorrect
jack or miswiring, check carefully to see if jacks are the correct ones, are
wired correctly, and are isolated from ground at the mounting point.

Ok Bob!
It appears that Google located your address to the east of where it really
is. My current take is that the photo was taken from the north facing south
and that your home is in the middle of the block. The buildings I
questioned must be the hospital.
While I still hate and mistrust computers, it is amazing what Google Earth
can provide for us.
The location at Pixley looks interesting. It even appears there might be a
runway there already!

. . . no. The top of the photo is south. The building to
the southwest is the hospital where dad and mom spent their
last days. That hospital was built when I was in the second
grade. I think my sister was either #1 or #2 patient when
she developed a high fever. The street in front of the hospital
is Walnut. The houses to our east face Cedar. The only
large buildings close to that intersection will be the hospital
in our back yard and the catholic church about 1.5 blocks to n.e.
Google doesn't have our location right, we're up the
hill between Cedar and Walnut.

The floats-on-a-swing-arm senders are
a legacy product from cars and other
vehicles that go back a very long way.
Making these things really accurate in more\
than one place is a bit fussy.
Years ago, we crafted an electronic signal
conditioning board for the Bonanzas and Barons
that allowed dead-on calibration of empty
and full. All other readings across the scale
simply fell where where the physics of the
sender dictates. The physics of these devices
are affected mildly by linearity of the wire
wound sensor resistor (usually within 5% of
true) but a whole lot by trigonometry of
the swing arm and tank geometry.
But as you've already recognized, the one
level you really want to be accurate is
the empty point. For this you can do some
things with series calibration resistors
and/or bending the float arm on the sender.
This CAN be a tedious, trial-by-error activity.
If it were my airplane, I'd probably craft
a microprocessor based signal conditioner
that would allow me to take readings at 5%
increments from empty to full and generate
a lookup table that converts as-installed
sender (transducer) readings into real
numbers. The BEST way to watch full levels
is with installation of a "dip stick" style
sensor at the low fuel warning level (generally
1/4 to 1/3 tank). Consider devices like this:
Emacs!
One of these stuck through the tank wall at
the warning level will light a lamp on the
panel at the desired fuel quantity with
no risk for drift of calibration. See:
http://www.gemssensors.com/content.aspx?id=282
This is the no-brainer, dead-nuts accurate
low liquid lever sensing method I know of.
Capacity fuel gages with processor augmentation
are also easy to calibrate . . . but I think
I could get by with no active fuel gaging
other than a set of optical level detectors
cited above.

Subject: | Pitot heaters . . . warn or not, that IS the question |
At 12:13 PM 8/8/2009, you wrote:
Bob..
The reason I asked is that I was looking at the events surrounding
Air France AF447 (A330) in mid atlantic.
I saw that AF and Airbus have been dinking around with pitot tubes,
and have been through three types (Rosemount, Goodrich, Thales
C16195AA so far, and were about to install the fourth type (Thales
C16195BA) just before the accident.
I was trying to envisage what can go wrong with a pitot tube...it's a
brutally simple device, and I came up with three scenarios:
1...Physical damage (Hail, catering trucks).
2...Insufficient heating.
3...Defective heaters.
As far as I can tell, there is no attempt made to monitor heater
performance, either by monitoring input power or by measuring
temperature., so I wondered if heating could be simply inadequate. I
came up blank when I tried to research the actual heater wattages.
Heating is almost never "inadequate" to the design
goals in place when the tube is originally installed
and qualified on that airplane. Problem is that
design goals and mother nature's ability to paste your
airplane with a layer of ice are not necessarily
in synch.
Incidentally...I believe that the primary causative factor was the
crew's decision (or non-decision??) to continue their planned flight
path despite the fact that it went directly through a monster
thunderstorm. The thing that is open to conjecture is the sequence
of events after that.
Hmmmm . . . The idea that an airplane becomes at
risk for unplanned arrival with the earth because
IAS/TAS values are suddenly "unknown" is a bit of
a stretch. But this assumes that some automatic flight
control system doesn't react and starts
fiddling with the airplane's configuration. In
the case I worked, the manufacturer wrote some specific
procedures for flying based on AOA in the rare cases
that airspeed becomes available. In any case, there
was no known risk that the event would occur during approach
to landing but even then, a landing using AOA and
windage corrected, GPS ground speed was quite possible
and practical.
If the heater is drawing current, then it's working
as designed. The Hawker-Beechcraft products nearly
all feature some form of heater current detection
to drive a light. This is spelled out as a requirement
in paragraph 1326 of both FAR Part 23 and Part 25
----------------------
Sec. 23.1326 Pitot heat indication systems.
If a flight instrument pitot heating system is installed to meet the
requirements specified in Sec. 23.1323(d), an indication system must be
provided to indicate to the flight crew when that pitot heating system is not
operating. The indication system must comply with the following requirements:
(a) The indication provided must incorporate an amber light that is in
clear view of a flightcrew member.
(b) The indication provided must be designed to alert the flight crew if
either of the following conditions exist:
(1) The pitot heating system is switched "off."
(2) The pitot heating system is switched "on" and any pitot tube heating
element is inoperative.
[Amdt. 23-49, 61 FR 5169, Feb. 9, 1996]
----------------------
If you'd like to include a similar system in your
heated pitot planning see:

Subject: | KLN 89B / 94 question |
Good morning, all. I am almost done with the wiring harness for my
avionics. It is down to the last two connections for the
GPSAPR/ARM/ACTV annunciator. The install data is decent, but missing
clear references to a couple of connections. Imagine that. I'm
hoping someone here has done it before.
On this annunciator, there are 4 inputs:
ARM Annunciate. This has a clear match on pin 17 of connector 891. No problem.
ACTV annunciate. Same, but pin 18. No problem.
GPS APPR annunciate. There is NO connection listed anywhere in the
documentation for this. Anybody done it before?
Finally, there is the lighting. I'm 14V, so there is an input on the
KLN for 14V undimmed, which tells the GPS to dim. That part is easy.
That "dimmer" unit also needs some sort of bilevel output for the
annunciators, since the KLN itself doesn't have one. Any ideas?
Thanks in advance.

Subject: | overvoltage problem |
All,
-
I have a 601XL/Corvair with the standard William Wynne configuration.- I
have the John Deere alternator and regulator plus the PMOV overvoltage unit
from B&C.- I feel confident that I have it wired correctly since I would
get 12V when I switched on the master, and then 14V when I switched on the
alternator and started the engine.- Recently I noticed my battery had a
low charge, and the voltmeter showed a flat 12V, even with the engine runni
ng.
I had the battery recharged and load tested (it was fine), and I tested the
alternator (around 40V ac on the two wires that lead to the regulator).-
The two wires that came out of the regulator and connected to the B&C capa
citor were showing just 0.05V or so when I connected each of them separatel
y through a voltmeter to a ground.-Clearly a problem.
So I bypassed the entire overvoltage setup and connected these tabs dirrect
ly to the system bus.- Now I get 14V when the engine is running.
I am at a loss to figure out where the problem is.- I believe it must be
somewhere in the B&C overvoltage system, but don't know where.- Fuses are
all ok.

Any ideas?

The Pythagorean theorem says that the line of sight distance between you and
the horizon is
D = sqrt(h^2 + 2hR)
Where h is your height above the ground and R is the radius of the Earth.
This assumes that the Earth is a perfect sphere and there are no mountains
or other stuff between you and the horizon. It's also the direct line of
sight, not distance over the ground (but close enough at the heights we
fly). Note that h, R and D all have the same units (feet, km, nm, etc).
Write this another way: D = sqrt(h) * sqrt(h+2R)
So, to a good approximation: D = sqrt(h) * sqrt(2R)
since h is generally puny compared to R = 3963 miles.
This gives the formula D = 89.03 sqrt(h) miles, if h is in miles or
D = 1.225 sqrt(h) miles, if h is in feet.

Two suggestions. If possible, find another aircraft with same model
radio, that you can swap yours into, and see how it performs.
Check your antenna cable thoroughly, substitute another cable and
antenna if possible. I had similar problems with old antenna cable that
turned out to have a cold solder joint for the shield on the radio end,
allowing lots of RF to leak back into the radio. New cable, problem gone.
If the radio has been bench checked with no problems, then the problem
has to be between the radio and the antenna, likely bad connection or no
connection.
One last long shot...turn coordinator or turn and bank are normally
wired directly to main bus to be always powered. If it has a noisy
motor, theoretically could be source even though nothing else is turned on.

Subject: | Re: Pitot heaters . . . warn or not, that IS the question |
Good Afternoon All,
The following passage was in a message to which 'Lectric Bob responded, but
I was not able to discern the author.
"Incidentally...I believe that the primary causative factor was the
crew's decision (or non-decision??) to continue their planned flight
path despite the fact that it went directly through a monster
thunderstorm. The thing that is open to conjecture is the sequence
of events after that."
I wish to respectfully disagree.
Staying out of severe weather is always a good idea, but airplanes have
been flying successfully through such extreme storms as long as we have been
flying IFR. As long as the crew has adequate instrumentation and the
requisite skills to use it the airplane will hang together. Back before we had
as
much deviation capability, airplanes were accidentally flown through
extreme hurricanes and even tornados. Some of the airplanes needed serious repair
following those excursions, but they did bring their payload safely back
to mother earth.
It is certainly wise to avoid those conditions, but the airplane will
handle it adequately even though it may be damaged and the passengers most
assuredly would not have a very pleasant ride.
I think you will find an effort by the applicable certification entities
to blame the crew for flight where they should not have been, but I think the
true story is that the crew either did not have the required
instrumentation available to them or that they were not properly trained in the
use of
what was available.
Blaming the weather is a cop out to avoid design or training
responsibility.
Happy Skies,
Old Bob

Attaboy Frank,
The most powerful stroke one can make is to become debt free. Lee and I
worked 3 jobs and ran a business for 15 years. I had no holidays off worked
all the shutdowns with contractors attended night school and designed
material handling facilities during the day. We were debt free in 1978
and stayed that way.
It's the shortest distance to care free living and our blessed
retirement of 5 years now. Thinking what might be worth building next.

Orthogonal. The phenomena don't lie along the same line, although they
do cross. Being on a farm doesn't really drive inventiveness or the
tinkerer spirit; however, being on a farm often means that you need
more than you have.
I wouldn't buy my son a car when he turned 16. I could have, but I
wouldn't. Made him go buy what he could afford with money he earned
himself. Turned out to be a clunker (go figure). He drove it a year
before burning the clutch out and then letting it sit for several months
while he slowly figured out that he could fix it or walk. My son is
probably the only one in his graduating class that can pull an engine to
replace a clutch.
The boy still couldn't slop a hog, but he is much closer than before to
the attitude that would get his feet muddy.

What this says, Rick, is that once our business experts and leaders
realize that a great country cannot be great without manufacturing,
they will attempt to restart manufacturing, but we won't have
qualified machinists and other similar craftsman/tradesmen to do it.
We will have to import this technology and expertise, thus creating a
whole new problem. It's too bad that our present leaders were and are
trained in MBA schools to maximize this quarter's bottom line and not
tomorrow's.
Well, for the most part, those craftsmen were imported the first time.
Yes . . . but so were the consumers, entrepreneurs, science,
manufacturing resources and individuals with creativity. It
was communication (letters, books, news, ships) with the
outside world that provided conduits of both information
and willing/capable souls who perceived an opportunity.
Wherein opportunity meant freedom of interference in the
conduct of free-market bargains and protection of liberty.
The older I get, the more I've come to realize that
the most important ideas were embodied in the schools
courses for which I had the least interest - history.
This is largely because my teachers idea of useful
historical knowledge consisted of remembering what
people did what to whom and when. I understand now that
the history of ideas is critical to success. It is
insufficient to school the student in the specialties,
hand them a room full of tools and expect a spontaneous
flow of value-added activity.
Folks like Kelly Johnson, Chas. Kettering, David
Packard, John Fluke, et. als. were not just sharp
dudes with an idea. They knew the history of their
sphere of ideas. It's gong to be a much more difficult
than to simply import warm bodies with the technical
skills. Unless we re-create the environment under
which our mentors germinated, grew and prospered, it
won't matter how many techno-wiennies, or stone masons
we import.

How about instead of smacking around Joe CEO that we modify our
country's business environment ? You know, like reducing corporate
taxation since our country has the highest corporate tax rate in the
western world. Or maybe reining in the insane environmental
regulations that allow non-involved 3rd parties to sue to prevent the
building of any kind of industrial infrastructure (like nuke plants or
oil refineries for example) for years to decades.
Complain about corporate stupidity and bean counters all you want,
but, reality is that any company that behaves differently will be put
out of business by it's more efficiently operating competitors (or be
put out of business by a nationalized company that no longer needs to
heed efficiency at all; I still can't believe I have to say that in
the United States).
If you want different results we need to change the underlying
fundamentals that are driving the corporate behaviors we all
(including me) find annoying.
Sorry for the political content. I do think being mechanically
competent is important.
But, with all the insanity going on in the US today I can't let
certain kinds of rhetoric pass uncommented. And, now that Obama
himself is telling me to shut up lest my neighbors report me, I'm
super pissed on top of it (I don't mean pissed or even annoyed at
Simon, my opinion just differs from his and Simon, as far as I know,
isn't trying to oppress me *smirks*).
c'ya,
Sorry,
Michael

Oh and I agree if conditions ever exist to make manufacturing
desirable on the level it used to be in this country the companies
would have a hard time filling jobs.
The thing is, that will result in high wages which will have the
follow on effect of people wanting to invest in learning those skills
which will stimulate the construction of trade schools, ad infinitum.
In a truly free market, the above problem isn't much of a problem
unless the desire for increased manufacturing capacity is time
sensitive because of an ongoing hot war.

Subject: | music input to intercom |
I finished the wiring harness for my PS 1000II, hooked it up and the intercom and
radio both seem to work good. The music input...not so good. When I plugged
in my Walkman (I know, I know, but my wife just gave it to me for my birthday,
it isn't being changed soon!) even with everything turned all the way up, I
could hardly hear the music. So I checked the circuit with the ohm meter between
music hi and music low and I get half a circuit - not a full short, just half.
I am using the shields for all the lo sides, connected them all together with
pigtails and then to ground at the intercom. Any ideas?

It's voodoo I tell you . I just switched on the A210 and the bloody intercom is
working just fine now.Looks like it just needed a rest. Maybe it got a fright
as I was just about to start cutting wires and installing a separate intercom
[403] so thanks for all your help. cheers Alan

Our corporate tax rate encourages companies to make capital expenditures
instead of report large profits. Businesses are quite able to decide
whether they report a profit or not. They often give raises or bonuses
which count as expenses against profits, adjusting the tax bill down.
This leads to another noteworthy statistic - America CEO's are very highly
compensated.. I'm not saying it's wrong, just that the tax rate is only
part of the picture..

Subject: | Re: music input to intercom |
You have a stereo source feeding a monophonic input, so you need to combine
the L and R channel outputs of your Walkman into the single channel input.
Usually, a couple of resistors connected together will take care of this
(150 ohms will work). It's best to use a stereo jack and wire the resistors
to the back of it. One resistor to L, one to R and connect the free ends
together to the mono input of the intercom (using the appropriate cable).
Good Luck
