Subject: | DO-160 and EFIS brownout |
I noticed that the latest publication of the EAA rag includes a nice ad
from the good folks at Grand Rapids Technologies for their EFIS. The a
d
claimed that they "exceed" DO-160 standards. Im not intimate with the
details of DO-160 but recall Bob recently chiding EFIS makers for thei
r
failure to provide brownout protection in their otherwise wonderful
products. Does brownout protection fall under DO-160 guidelines? If s
o,
perhaps now is a good time for us to gently prod them toward compliance
in
view of their claims.

I have the blue and white

to do battle with keep on rebending it and once in a while lose a pin.
I have universal tool from Spruce but largest insert it is not big

High quality? Well, no.but I know of a cheap and elegant (in a cheap sort
of way) alternative. ;>)
Purchase a set of inexpensive jeweler screwdrivers. Try the Dollar store,
Walmart, etc. The screwdriver part is usually glued in to the silver colored
handle. Yank out the screwdriver tip then bore the end to the appropriate
diameter. Next grind the outside diameter to allow the 'tool' to fit through
the connector. I did this in about five minutes on a scotch-brite wheel. You
will have to examine what you buy as to whether you can successfully modify
it to work. In other words, is the handle tip where the screwdriver tip goes
long enough to bottom out on your connector such that you can bore and grind
it to do the job?
And the total price for the two tools I needed for the two sizes of Amp
Mate-N-Lock connector pins I needed? @$5.00 total as opposed to the $50.00
plus you will need to order/wait for the two (20-24awg, 14-18awg)
professional tools.
I came up with this 'solution' late at night on a weekend so I could
continue wiring my RV8. In addition to making my panel 'plug-n-play' (read
accessible), I was able to do some complex wiring at the connector rather
than at the switch.
Close examination of the pro tools leads me to believe these are just brass
tubing (no slits) with a handle. You could check a local hobby store to see
if per chance they have the inside and outside diameter tubing you need in
their metal hobby rack. If so that would be an even better solution.
Oh, I recommend the AMP brand Mate-N-Lock as opposed to the non locking
Molex stuff you get at Radio Shack.
I don't have exact dimensions as I am away from the hanger.
Regards and Good luck,

Hi Bob,
After spending much time convincing one of my buddies to install an OV

Have they disappeared or did I miss the obvious ?

Looks like they revised their web site since my last visit. Much
nicer. Look under "Regulators" in their "Featured Categories"
section. The crowbar modules are built-in to their alternator
controller/ regulators.

Ron,
I know you want to use the right tool.
Each tool is specific to a pin/socket combo and as you
know each manufacturer's pins are different sizes.
Go straight to the molex web site and get the p/n then go to
digikey or newark, etc.
FWIW, I removed all the molex connectors from my airframe
because they are the least reliable I know, highly prone to the
connectors backing out of the bodies secondary to vibration.

Thanks Bob and for all your contributions to our experimental industry.
There is nothing wrong with the e-buss relay, except it's more
connections and another device.
I think my confusion was caused by the standard z-15 schematic and how a
7amp e-buss alt feed fuse can power the e-buss when the e-buss (as
shown) could be much more than 7 amps.

Yeeaaahhh . . . sort of.
When somebody says, "We meet or exceed DO-160 standards,
it can mean a lot . . . or very little.
DO-160 is not a standard. It's not a requirement. It's
a catalog of suggested investigative/proof tests for
demonstrating that a particular piece of equipment is
suited to the intended task. See:
http://www.aeroelectric.com/articles/DO-160.pdf
Obviously, we're more concerned about performance for
a heads-up display than we are about the battery bus
voltmeter. Environmental conditions in the forward wheel
well are light years away from those of the galley
warming oven.
So one of the first issues for purchasing any new
piece of equipment involves an agreement between the
buyers and suppliers as to what tests will be run
and under what levels of stress and what constitutes
a pass-fail condition.
The final agreement takes the form of a Qualification
Test Plan (QTP) that speaks to all those features and
is blessed by all interested parties before the program
moves forward.
When the "pass" condition has been demonstrated for
all tests, then a certain document is filled out
that may look a lot like this:
http://tinyurl.com/cvqth2
As you can see, this form has a place to speak to
the entire constellation of DO-160 tests. I'll call
your attention to notations for Section 9.0, 10.0 and
others where we're told that this feature is "Category
X, no test performed."
Further, there should be a mini-synopsis of the
qualification test form as part of the device's
product identification label where you will see
a string of characters like this:
Emacs!
If you know how to decode this string, you can learn
a lot about how the device was tested. Note the
multiple appearances of "X" in the string. Those
are tests that were not performed. The other letters
speak to tests that WERE performed and to what
levels.
Sections 16.0 through 20.0 speak to a host of input
torments including power interruptions and brownouts of
various magnitudes and duration. The goal of performing
these tests is to show two things: (1) the input power
anomaly doesn't damage the device and (2) if the
device wanders into the weeds as a result of the
stress, it should demonstrate some "acceptable"
mode of recovery. Here's the ace-kicker. For some
products, it may be acceptable for the operator
to carry out some action to drag the device out of
the weeds. In more critical cases (like autopilots
or flight displays) we might agree that the screen
can glitch or the ailerons twitch but recovery after
the event is autonomous, timely and pucker-free.
With respect to your question about brown-out,
yes . . . there some tests that touch on that.
But without reading the test plan for a device
and knowing what the interested parties called
"acceptable recovery characteristics", the statement
that a product "meets or exceeds DO-160" has
a risk of being vague and/or not very satisfying.
In the case of a processor-based system parameters
display, the critter may go nuts during the event
but stand up in a few hundred milliseconds. I
think I could live with that. For the early
versions of Blue Mountain flight instruments
systems, the processor had to reboot from a
hard-drive. This could take some time and if
it happens in flight, raises questions as to
accuracy of the displays after they quit
thrashing around.
As you can see from this mini-dissertation on
equipment qualification, designing to live in the
sandbox with really big cats is not a trivial
task. Further, DO-160 speaks only to the effects
of environment. You still have to thrash out
an agreement on ability to perform the intended
task.
My occasional accusation that certain products
were "not designed to live in the real world of
airplanes" is not intended to be flippant or
demeaning. It was a simple observation of fact
that should give the OBAM aircraft builder pause
to insure that system integration into their
project is accomplished with understanding.
Back to your original suggestion: It NEVER hurts
to inquire as to exactly what DO-160 tests were
run and even ask to see a copy of the cert sheet.
If they've done a good job, they'll be proud to
show it to you.
Bob . . .

Depends on the specific connector. There are a number
of "similar" products which can be inserted/extracted
with a tool for another series . . . but as you can see
here:
http://tinyurl.com/clkq9t
http://tinyurl.com/dc6j2y
there's a whole fist-full of tools for the Mate-n-Lok
series connectors. Further, be sure you're not really
looking for a Waldom/Molex tool. Lots of folks mistake
the W/M parts for Tyco-Amp.
Your description of a "blue anodized tool" reminds me
of this critter:
Emacs!
This is the Molex 11-03-0006 for the larger, .093 power
pins which are 'close' to Tyco-Amp Mate-n-Lok but no
cigar. The smaller .062 power pin tool is red. But
Digikey will have the tool you need once you figure out
which connectors you're working with.

Hmmm . . . that was the OVM-14 which is part of their

I'll cc Greg on this and see what's up.

The z-figures are intended to show architectures that
can be tailored as to what alternators, regulators,
batteries, starters, fuses/breakers, are appropriate
to the task.
The wire and fuse sizes are examples for the purpose
of illustration . . . any and all can be adjusted
to meet your unique requirements.

I just ordered an OVM-14 by itself and the kit which included another
one. I had to call them to get the individual one. They wanted to
know what I intended to do with it before they would sell it to me.
The kit was for my PM alternator and the individual one was for a
ground power installation per the Z-??? drawing. They were fine with
that use.
The sales rep said they had become concerned with some installations
people were doing. I didn't ask for details about what they were
concerned about, only gave him my use.

I was working at Cessna when the Amp Mate-n-Loks
came in the door. This would have been about 1968.
After years of paying homage to "aircraft quality"
connectors at Boeing and Cessna, I was skeptical
of these cheesy looking connectors.
In the intervening years, I've had numerous
occasions to ask FBO mechanics what problems they've
had to fight with those connectors. The complaints
were surprisingly few. If these things don't get
splashed with water or mechanically damaged, they've
held up well.
Of course, this presumes they've been installed
to the manufacturer's specifications.
