I just posted the following to the AOPA "Never Again Online" forum.
You can read the original article at:
http://www.aopa.org/pilot/never_again/2004/na0411.html
--------
Here we have another scary story in the "Never Again
Online" column. This one from a man who suffers from a
failure of the charging system, recognizes the fact, and
then does just about everything wrong, surviving by,
"The Lord must have heard my wife's prayer because I
know I was not a good enough pilot to have come through
all this without a scratch." Oh please Mr. Stone. What
a load of road apples.
This "Never Again" has *nothing* to do with a failure of
the charging system at night and everything to do with a
pilot who exhibits not even the slightest familiarity
with his airplane and poor decision-making skills to
boot.
Mr. Stone, you took a simple minor system failure and
through poor decision-making and failure to understand
the basic functions of your airplane turned it into
something much worse, at least in your mind. Even so
the whole thing should have been handled easily.
Maybe this event will prompt you to get some training
and practice with your airplane before you become a
statistic and affect my insurance rates, not to mention
causing the FAA to issue yet another unnecessary ruling
to protect us from ourselves.
And if I were your wife I would have slapped you silly.

Hi Bob-
No, same DROP when either mag switched off, just as you probably did a better
job of explaining than I did- what I should have said instead of "absolutely
identical" was that I could perceive no difference with my untuned ear! The
original question was the desire to accurately determine rpm during mag check-
not sure how accurate this has to be to determine the relative condition of
each ignition system... easy to do with the ear, and no added complexity to the
plane-

Understood- but what does the actual number really mean? If I switch off
either mag and nothing happens, I know that entire system is either not working
at all or not grounding- If I switch either mag off and the engine runs rough,
then there is likely something wrong with an individual plug/wire system.
Both of these failures would seem pretty obvious to the ear. What else can a
mag check really indicate?

Agreed, Brian. However, you must give Mr. Stone a least a little bit of
credit for writing the article in the first place. After all, if YOU
did something really stupid while flying YOUR airplane, would you have
the courage to write an article about it and expose yourself to public
humiliation?

Interesting story...the thing I find odd is that at the very end about what was
learned is that he doesn't mention anything about believeing his instruments
even though "I was still not convinced that the ammeter was discharging." I
wonder why he was convinced that it was charging? I find this discouraging
since he's apparently an instrument rated private pilot and faith in your
instruments is compounded even more, IMHO.

Oh, you mean the time I ran out of gas and had to make a dead-stick
landing at Brackett Field in Pomona while on a supervised IFR
cross-country for my commercial ticket? Yeah. That story was in
Flying Magazine's "I learned about flying from that" series about 25
years ago. It ended up in their collection.
That was an interesting chain of errors that lead to bad decisions but
I had the help of my CFI to make it happen. Oh, and one of the
problems was unfamiliarity with the aircraft I was flying. It was the
first time I had flown that type of aircraft. When we landed in San
Diego I wanted to refuel the aircraft but the CFI nixed it. I was the
PIC but I abdicated my responsibility. It showed how an incident or
accident requires a chain of events; that you can break that chain at
any point and prevent the incident/accident.
So, yes, mea culpa. It makes me more sensitive and leads me to
emphasize decision making and understanding the aircraft when training
my students.

That had also crossed my mind. It also reinforces that old adage:
"It is better to be down there wishing you were up here than to be up
here wishing you were down there."

Anybody know the sensitivity of the UBG16 inputs used with external
"function modules"?
In other words, how many mV at the input does it take to display
1000 or 1999 on the UBG readout?
Another question. How much filtering is there inside the instrument?
In other words, how much filtering is required externally if you
want to use the UBG 16 as digital voltmeter to read the "average"
voltage of a signal that might have a 10% ripple at several hundred
Hz.

Excessive drop on one mag with a smooth-running engine: mag timing.
Excessive drop on either mag even if the difference is within specs:
mixture.
Do you ever watch what the EGT does when you turn off one mag? If you
have an engine monitor seeing the amount of the EGT rise will tell you
something as well (higher than normal EGT rise probably indicates late
mag timing and will be accompanied by a greater-that-normal RPM drop).
One of the important things is to know how your airplane normally
feels, looks, and sounds during a normal run-up. What is the normal
drop for each mag? What is normal EGT rise on one mag? What is the
manifold pressure at the run-up RPM normally? Where does the oil
pressure sit at idle and run-up RPM? If any of these things change it
is grounds to wonder what has changed in the engine even if everything
is still within "normal" specs.

I wasn't really following this so I apologize if this is already answered in
this discussion.
I was planning on the Grand Rapids EIS for my M14P. To be able see the RPM
on each mag I will need a switch to select which mag runs the tach., or at
least that is the simplest solution??

I haven't looked closely at the GR engine monitor but doesn't it have

Hi,
There are a lot of these "never again" stories that
are like this. I usually learn from them, even if
the author's conclusions don't match my own.
What I can't quite figure out is why anyone would
fly any distance without a handheld radio, and
without a portable GPS. These things are very
cheap, and they are very cheap insurance.

Dead on accurate analysis sir. We've often
heard the adage that a pilot's license is a "license
to learn" but all too often, learning seems to slow
down or even cease.
The FAA is fond of developing new requirements for new
production but allowing older airplanes to "grandfather"
along in their originally certified condition. For the
most part, I agree with this philosophy but with one
exception. If I were made "Emperor for a day" of the FAA,
I'd write a requirement for low voltage warning, periodic
cap tests of batteries -OR- yearly replacement, and
and dual feed e-bus installation for all aircraft that
are used for night-cross-country whether VFR or IFR.
It's probably the simplest change we could make to
any certified ship and would make the vast majority
of electrical system dark-stormy-night stories go away.

This is a fairly old thread (but I remember your comments) . . . but I'm planning
my breaker / switches and "rough wiring" for my RV-8.
Without Avionics I'm figuring the following night IFR load on approach?
Heated Pitot 10A
Landing Lights 8A
Nav Lights 8A
Strobes 8A
Panel / Inst Lts 2A
Gyros 2A
Total 38A
I may be a little high but should be close?? What am I doing wrong?
Thanks,
Bob Christensen

I am not sure if it has two inputs. I was assuming it only had one based on
the post by Mark (Fiveonepw) who said his EIS4000 is only on the right mag.
I could have misunderstood his post.
I will check with GRT.

I haven't looked closely at the GR engine monitor but doesn't it have
two mag inputs to avoid the problem?

I did in my Comanche. My "fix" is 20 years old now and my e-buss is
called the "Avionics buss". It was easy when we did the new panel back
in 1984.

OK, no one has any idea where I can buy a little "patch cable"
like the one listed below? I guess I could make one, but
when I was running a big IP network, I had a rule that none
of my guys were allowed to make cables. Too unreliable.
Not sure I want to break this rule with my radio antenna.

You can get a cheap, digitally tuned portable radio and extended the DC
power and headphone audio leads from outside to inside via a hunk of
4-wire telephone cable. Wrapped the radio up in two layers of zip-lock
plastic bag along with a packet of silica-gel. Install it under a plastic
bucket to shield from direct effects if wind and sunlight.
At the other end, attached a wall-wart power supply and a set
of amplified computer speakers. This keeps all your wiring
close to the building and relatively immune from lighting
strike issues. Signal strength to the radio is very good and
should offer excellent quality audio. Leave it turned on 24/7
and just turn down the volume when you're not listening to it.

Mickey,
Since nobody else replied, here's my suggestion. Check with Garmin, or
ICOM. My GTX-327 transponder uses a similar plug that comes in either
straight, or 90 degree. It is listed in the parts list at the back. I
could get you a p/n, but I would think that any avionics shop should be
able to get one for you.

My 2002 vintage EIS4000 has only one, which would require a switch and
resistor for both p-leads- my unit came with the required resistor for one mag...

Hi John! And I agree with both of you- in our area BBC is avialable via NPR
on AM along with a virtual dearth of mind-numbing advertising- hence my
interest....

Ok, neat idea- but what do I tell the airport authority the weird new
appendage to the roof of their new hangar is? 8)
I actually did consider this using a Sony Walkman beltclip radio (amazing
reception!) but ran into the "changing the battery" problem- this sounds like a
workable solution! (provided Brians antenna loop falls short- I'm trying that
first- lots easier to change channels!)

No the Avionics are probably another 10A peak?

Hi Bob
Maybe we do things different here in the Great White North but the heated
pitot and landing lights are considered as "intermittent" loads (at least on
my load analyses) which may exceed the normal continuous rating.
The pitot heat would only need to be on if you anticipated icing and the
landing light for a very short time before touchdown!
