| Subject: | A Message From AeroElectric's Bob Nuckolls... |
Dear Listers,
The well known Bob Nuckolls of the AeroElectric posted a great message Monday on
the AeroElectric-List regarding the Matronics Lists and the importance of supporting
the operation during the Fund Raiser. Please take a minute to read Bob's
commentary below, reposted to the other Matronics Lists with his permission...

I will add my voice to this suggestion. It's
easy to enjoy the benefits of what's available to us
off-the-shelves at the corner mega-marts. It's
seldom that we give pause to learn and understand the
processes and tools that made it possible to reach out
and select from dozens of options.
This, and all civil societies, runs on talent, energy
and mobility. Mobility exploited by thousands of hands,
machines and transportation that figure into the
'infrastructure' that puts the boxes of Wheaties and
Pop Tarts on the shelves.
See "I pencil" http://tinyurl.com/36xkhq
Any break in that chain of time, talent and resources
at least interrupts if not totally halts flow of
that benefit. Matt's room full of byte-thrashers is
like the natural gas pumping station a few miles from
my house. If those pumps stop, who ever is expecting
the furnace to come on at the other end of the pipe
is at risk for reduced service and/or higher costs
for that service.
Matt's yearly endeavor to keep his pumps running is
a trivial burden on the members of the Lists
but of incalculable value to those who participate
on them. No donation is too small.
We go to a fly-in a willingly chuck a few bucks into
the coffee can at the drinks and donuts table, let's
chuck a few bucks into Matt's coffee can too. 50,000
pounds of value doesn't get to the shelves on time
if one 18-wheeler runs out of gas. The T-bytes of
data flow we all enjoy don't get from your keyboard
to the screens of others unless Matt pays the light
bill and strokes the machines to keep them happy.
No, $5 won't get you a free copy of the 'Connection
or a fuel sampler but it will go toward the assurance
that logging onto your favorite List will open
doors that you would be sorely missed should you find
that hitting the return key doesn't produce the
expected response.
$5 from every List customer on Matt's system will
go a very long way to keeping the byte-pumps running.
$More$ will go a long way to upgrading the size
and quality of the machines as the old ones get
long in the tooth. No matter what size of donation
you choose . . . please do it now . . .

Geoff, as I mentioned, I love the stuff, but I discovered too late for
most of my project.
Did you use it on the exterior of the cowling or cabin top? I assume
you did but just wanted to regret some of my earlier choices a bit more.

| Subject: | First ice of the season and why a heated pitot is nice |
Just thought I'd share...
Monday a week ago, when the storm hit NY/NJ/CT, I had the pleasure of
flying from Key West home to NC.
https://dl.dropbox.com/u/60509998/FlightAware%20%E2%9C%88%20N215TG%20%E2%9C%88%2029-Oct-2012%20%E2%9C%88%20KEYW%20-%20KSOP.htm
The weather was interesting in that I don't think I've ever flown for 5
hours in a single low pressure system. The barometric pressure at
takeoff was 29.xx and steadily sunk by 2 or 3 tenths every ATC handoff
until landing. And I was still well short of the stormy center. The
winds were strong from 3,000' up to 10 at 40+ knots but they were the
same speed the whole way up and they didn't change by more than 5 knots
for the whole trip. That's a big fat low.
In the keys we had fair weather cu but from FL thru GA there wasn't a
cloud in the sky. Somewhere over SC cu formed below, solidified, and
slowly rose to meet us at 10k. Temps at 10k were above freezing all day
but as we started to hit the layers the temps were coming down and I
noticed a few glazed drops on the wing's top surface. I was checking
the leading edge for any build up but didn't see any.
One of the first accessories I purchased for the '10 was the Gretz
heated pitot. It seemed to be a well designed product now available to
me because I'm 'experimental'. It had been installed for 4 years when I
finally put power to it. It seemed to work but there's no easy way to
confirm it's exact operation. However, a subsequent inspection showed
that the thermoplastic exterior had melted and the fuse had blown. The
pitot function was still there but heating was clearly not available. I
flew like this for quite awhile weighing my options. Since purchasing
the unit, the Gretz product had been sold to Angus Aviation in Australia.
http://www.angusaviation.com/HeatedPitot/tabid/608/language/en-US/Default.aspx
hmmm.
After several conversations with Andrew Leopold at Angus, he convinced
me the only way to fix this was to send him the unit. Taking the pitot
off and sending to Oz basically put the plane offline unless a
substitute pitot was fabricated. So I went back to the Vans 1.0 pitot
design with a little hacking and sent the unit off.
It came back a couple of weeks ago. I learned 1) sending small stuff
like a heated pitot unit to Oz is surprisingly fast, cheap and easy via
1st class mail, 2) Andrew is a class act, he fixed it and made me whole,
3) I'm real glad I had a heated pitot last week...
So, I'm flying along looking for leading edge ice and watching the
indicator lights on the pitot flash on and off. It slowly dawns on me
that the plane is slowing down. I've lost about 15 knots indicated! A
closer inspection of the leading edge shows that I've got a pretty good
layer of rime on the leading edge. I ask for and get lower. I'm able
to Pirep the icing and the freezing level at 6k ("what's that noise?"
"that's ice baby, I think we're shedding ice off the prop").
So we land at KSOP, aka the land of golf courses. Twenty five knot
crosswind, blustery, rain, dark, etc. I ask for gas, wearing my
sunglasses, sandals and T-shirt, wondering why everyone is so
overdressed. Wait, I'm the one that is underdressed! One of the
surprising joys of IFR flight.
I don't know what an iced up pitot would do to my AP guided machine but
it would not be good I assume (does anyone know?). I know I REALLY like
the Gretz unit now that it works properly. It's just another completely
automated device that I only need to monitor. It periodically heats up
and shuts off as the temp drops. I notice that the electrical load,
like any heated pitot, is substantial when it's heating but it only
heats to the extent it needs to which is a good thing if your electrical
system is at or near full capacity. No more burns during preflight. No
more having to remember to turn it on. And no more eye pokes from the
high wing installation on my old Maule... I'm a low wing guy now.
So, with all this talk about options, I would highly recommend a heated
pitot and the Gretz unit in particular. Certainly for any IFR work but
also for VFR unless you only go traveling short distances on sunny
days. The '10 is an amazingly nice traveling machine that likes to go
high and long. Yes, I flew slightly over 5 hours with only 60 gallons
on board and I still had almost an hour of low power endurance left -
far less than I would ever plan for or depend on but enough when high
over VFR airports over familiar territory dotted with available fueling
spots. At 10k I'm burning less that 10GPH with WOT the whole way. LOP
of course.
What a storm. After fueling up I flew VFR under the clouds home to
8NC8. I was tired, it was dark, and Sandy was intensifying every mile
we flew north. ATC was more than helpful as I garbled almost
everything said and screwed up a vector to get around RDU. I had to do
a crosswind, downhill night landing on our little grass carrier deck.
It's much easier to do in the '10 than my old lightly loaded tailwheel
Maule. A very satisfying end to a great trip. The '10 is sweet plane!
So, put a heated pitot on it if you plan to fly it seriously.
Does anyone have some thoughts on what could be done to make leading
edge icing more easily visible from the cockpit? I have a white wing
and was thinking that a patch of paint or something might make ice
easier to detect but I don't know. Thanks for any suggestions.

I've seen a little rime on my grey metallic painted wings. It was pretty
evident, and so light I didn't notice any performance decrease. We could
see it on the windshield, too. We were in and out of the tops of clouds so
we had plenty of light. I think you're right though, white wouldn't show
the ice nearly as well.

Leading edge ice shows up great on my Lamborghini purple wing.
