Hi Bret-
>Soo...I would not think this applied to experimentals with the special
>airworthiness category.
I concur. This ties in directly with the conversation over at aeroelectric
where the topic is a particular fed requiring a 337 for GPS installations.
The only thing on an experimental that is actually required to be TSO'd
(certified) is a GPS that is used for terminal ops. Nothing else. Now,
realistically, if one chooses to build their own com radio or transponder,
proving TSO compliance could be a bit problematic. Actually GAINING a TSO
is a separate issue, and relates to marketing and use in the certified
world.
It's curious how we, as a group, can get so caught up in the details of the
bark of the particular tree we are looking at that we forget which forest
we live in.
As an aside / FYI, and if I recall correctly, one of the composite props I
was familiar with had a metallic spar that ran virtually to the tip of the
blade, and the other had wire mesh embedded in the outer strata of the
blade. Both had nickel leading edges for rain / FOD protection, but also
provided a conducting path for lightning. One of the two airplanes was a
lightning magnet, and our company experienced many strikes, with no prop
damage that I recall. Rudders, on the other hand.....
Do not archive this particular ramble ;-)

I think ON/OFF is fine, but if you want to control it try a
PWM (pulse width modulation) control "rheostat".

Here I looked up some ideas:
http://solorb.com/elect/pwm/pwm1/
http://www.electronickits.com/kit/complete/motor/ck1400.htm
http://www.electronickits.com/kit/complete/motor/k166.htm
http://www.bakatronics.com/shop/item.asp?itemid=581
I think ON-OFF switch is fine. You will probably NEED
all the air you can get from a little FAN.
I suggest you get LARGER fans than what you have.
You will get very little air from those tiny fans. Have you
felt the air off of them? You will likely get a small 1.5"
spot above the fan clear and that is it. That is not too
great of a vis.
I am debating putting any fan in at all.
My back up is a cig lighter portable ceramic heater/fan
window defroster heater and just throw it up there on
the glare shield on the ground to get it defrosted. I might
put some vents to allow the cabin heat & radio heat to
rise up with natural convection. I'm thinking weight.
I am not saying don't do it but I would get much bigger
fans, and as far as speed control? I'd go with ON/OFF.
You can add speed control later if you need or want it.

I just replaced my APRS tracker in the RV with a more powerful 8 watt model,
as the 300 mW unit was giving erratic results. If everything is programmed
and calibrated properly, and if I can get the wheels to roll through the
snow on the turf strip, I will be conducting a trial flight is a few minutes
to check it out.
The following link should enable tracking in real time. If all goes well,
the last recorded flight track from November will be replaced with current
data. http://aprs.fi/?call=N30yd&mt=m&z=11&timerange=21600
I should be airborne by 16:50 EST.

| Subject: | Re: APRS tracking technology as alternative to SPOT |
Replying to my own post, here- too many things wrong with the flight so I
stood down. Garmin 296 wouldn't lock onto more than 2 birds, and thought
the local time was 11:36 AM, so it acts like the internal battery is going
south (flown as recently as last week) - but the unit powers up fine on the
bench using just its own battery, as I write this. Directional control on
the snow was awful, even though there was lots of grass showing - just too
much cover. I think I packed the wheel pants with snow in short order. I
couldn't even hold brakes against a 1600 rpm run-up without sliding. When I
was about 50% beyond my normal rotation point and still hadn't broken
ground, weaving like a taildragger pilot in a crosswind (gulp!) I balked the
takeoff. Barely had enough braking action to execute a 180 within the width
of the strip.
This is disappointing, since I wanted to fly tonight and wanted to demo the
APRS, but I guess I get an "A" for decision making. Even if I had had hull
coverage I don't think I could have felt good about completing that takeoff,
knowing I'd have to return to that same runway in a few minutes and try to
stop safely, possibly with frozen brake pads. The weather is supposed to
turn here tonight, so that was probably my one window to fly for the next
week or two. Snow expected again tomorrow and a deep freeze on top of
that. Should stay mushy out there till about April even if the snow
dissipates. Some days are like that.
I'll post a heads-up if /when I try the airborne APRS again. Meanwhile I'm
going to have harsh words with my 296.

Not sure, Chuck. Java scripts, maybe?? I just clicked on it and it
displays a beautiful depiction of my figure-8 over Lexington.
Unfortunately, that's not today's flight, which, as I posted a while ago,
was aborted due to snow pack on the runway and lack of tundra tires on the
RV :-)
The 296 straightened itself out about 5 minutes after I lied to it and told
it that I had stored it without batteries. It now shows correct local time
and position. Pretty finicky for a $1400 unit that wants to moonlight as a
doorstop. If it continues to misbehave I'm going to stop feeding it
electrons and make it come to heel.

That's pretty neat.
So what's the coverage like? I think someone's previous post said that the
range can be 100 miles, and the repeaters would take it from there? How
dense are the repeaters?
The main benefits of the SPOT system right now are the GPS coverage
(effectively unbroken coverage across North America), and Satellite Phone
uplink (ditto).

I hope your 296 doesn't keep going south like my 396. My 396 loses it's
location almost every weekend - for sure if I miss a weekend flying. It
takes 5-10 min to find itself if I tell it to use a new location - but at
least it's still useable. I've talked to Garmin tech support a couple times
and their drill is to get the latest software update and to purge the
satellite almanac. Power up while holding the zoom out key for ~12 sec will
flush the almanac (at least for the 396) and then leave it on in the open
for 30-45 minutes to download a new one. That has not cured my problem so
they tell me the next step is to send it in for the $350 flat rate repair...

Hi gang
While we're on the subject of tanks...
Mine has leaked from day one. Eight years ago. Every so often, like
at annual time, I clean off the offending area and the A&P smears
some goo on the leaking area. Well, its time to take the tank off and
remove the leaking plate and maybe replace the sending unit. I have
never done this. Is this a big job? Can any of you give me some
suggestions? Like what to watch out for.
Thank in advance.

Bummer. One of our 430s had the same issue after we got it back from
sending it in for the WAAS upgrade and it had to go back to the factory.
Fortunately it was under warranty. Any chance the internal battery is
losing its steam? Does anybody know if the battery pack contributes to
holding memory while the power is off?

| Subject: | Re: APRS tracking technology as alternative to SPOT |
The repeater infrastructure is fairly good all across the country, I'm
told. For aerial use, the repeater coverage is not really an issue because
the line of sight is so good (in the absence of mountainous terrain
obstructions.) All we need for internet tracking is to have the position
packet make it to a single I-Gate station that posts it to the APRS web
server. That's much simpler in many ways than trying to send a position
report from one terrestrial station to another by a series of digipeater
hops. I use a path of WIDE2-2 from the plane, which gives me 2 hops before
the message dies. If any of the stations involved in either hop is an
I-Gate, I'm golden - my packet is stored on the server from then on, to be
recalled by whatever viewer one might use - even months later.
The drawback to APRS is that there is no closed loop or acknowledgment of
the packet sent back to the originating station, so one must simply hope
that some of the blind (unproto) packets have gotten through. Make sense?
I think the only real advantage that APRS might have over SPOT is the cost
(free once you have the tracker). Well, fully implemented APRS, which I
don't have and don't plan to set up in the plane, would allow two-way text
messaging - I think the SPOT only allows one way.

I have done this a couple times.
Carefully remove the tank cover with a wide blade putty knife. Remove
sending unit.
Clean all mating areas very well with lacquer thinner.
Assuming the plate is not went or warped, get a new cork gasket from Van's.
Get a new gasket for the new sending unit also.
Be sure everything is very clean (PPG wax and greaser remover is good. Also
Dupont 3812S reducer or Coleman Lantern Fuel).
Seal all mating surfaces with PermaTex Aviation Form a Gasket (get it at
your auto supply store). Use all new cork gaskets.
Remount the sending unit and the larger tank cover using socket cap screws
and washer. DO not over tighten them.. Just snug them up.
Let the tanks sit for a couple days before reinstallation.
I have never had a leak using Aviation Form A Gasket.

That's correct, and it's the one minor downside to the SPOT system.
Messaging is one-way, and you have only three messages you can send ("I'm
OK", "Friends, I need help", and "Send the cavalry", effectively). The
major downside, as you point out, is the yearly cost.
What's the weight of the hardware necessary for APRS? How easy would it be
to remove from a downed plane if you needed to and/or decided to leave the
crash site? One benefit of SPOT over ELT is that if you need to move, you
can bring the beacon with you and trackers will know that you've moved and
know where you are.

Really dumb question... Do you take the tanks off of the wing first or
do it in place?

Very well done write-up Mark. It must have taken a week to write "hunt and
peck" style. ;) I really think you should fly down to Georgia and do my
wingtips. This would allow you to further refine your technique. Heck,
I'll even slap some road kill on the grill and feed ya! How 'bout it?
