Bob et all,
One of the first things every builder is told to do when designing the
electrical system for their OBAM aircraft is to determine the type of flying
they intend to do, figure out what equipment they need to comfortably fly
that way, determine the CONTINUOUS load of that equipment, and size your
bus's, wires, fuses, alternators, batteries, etc. accordingly.
It is information that seems pretty hard to come by in most manufacturers
specs, yet supposedly everyone who has designed a panel and electrical
system to support it has needed this info. Where did they get it?
It seems to me that one of the most valuable resources that could be made a
permanent yet updatable part of this list either in the FAQ's, or archives,
or somewhere, would be a list of the most commonly used equipment (I don't
think it would really be that long ) and continuous load numbers for that
equipment. I'm not saying this should necessarily be a job for you (although
your contributions would certainly be welcome), but just a have this forum
as a home for the list.
It could be a categorized list ( Nav/Coms, Coms, Transponders, MFD's,
EFIS's, T&B's etc.) and be something that subscribers could add to, and
update as they found numbers for new equipment as it hit the market, yet the
older equipment would still be there for those not using the latest, and
greatest in their plane.
Is there some place that you or anyone else on this list knows of where this
info is readily available?
Thanks for your thoughts, and any light you can shed.

that's been discussed. A number of members on the List
have published their load analysis data. I've posted a few
of them at:
http://www.aeroelectric.com/PPS/Load_Analysis
What you're suggesting would be a great resource
and as I recall, some folks volunteered to compile
the list . . . but it has not been discussed in some
time.

There is no requirement to twist PTT wires. I often twist pairs or trios
of wires specific to a task just to keep them together and easily
identified in a wire bundle. Also, twisted wires put lower stresses
into the strands for situations where you're bringing PTT wires up
the control stick and the wires will be subject to a lot of flexing
at the bottom.
You can use the wire you've cited . . .

are all the active aviation gps antennas (trimble, king, garmin, lowrance,

which specificiation do i need to look at to evaluate the equivalence?
=====================
Only if you believe all men are created equal!
The difference is whether they are active or passive.
Passive does not offer any GAIN.
Active offers a built in amplifier which offers some gain. NO additional
wiring is required if you get an Active antenna.
On LONG runs of antenna coax you may want a bit of a foot-up with an antenna
with gain. What is a long run? I don't know. My Passive antenna came with
about 10 feet of coax and works well.

For those of you that are using/considering a 17AH 12VDC RG battery for your
craft you might be interested in what I just found out when looking to get
another Panasonic 17AH 12VDC RG battery. Panasonic now has a 20 AH battery
that is only .22 pounds heaver at 12.56 pounds and it only costs $6.69 more.
That looks like a good deal to me. Here is the info from
http://digikey.com. DigiKey has links to the factory datasheets for these
batteries.

Price
P174-ND LC-RD1217P BATT SEALED LEAD ACID 12V 17AH Panasonic - BSG $40.67

Looks interesting. I think you meant to say "14.56 pounds," though.
Wouldn't you know I just ordered my third Odyssey PC-625 for the plane
last week. Maybe next time I'll try one of these.

On second thought, having just looked up the Odyssey, the Panasonic is
1.3# heavier, and its numbers don't look any better to me (except
price). Maybe I'll stick with Odyssey until something better comes
along.
(IMO, $30 is a fair price to shave 1.3# from an airframe. At that
price, I'll take 200# off, please :-)

John:
Not Enough Good Information (N.E.G.I.)
I'm guessing ... The "outlet" is a cigarette lighter jack???
Since you have three wires:
One is for an internal light.
One is B+
One is GND
The center is B+
The case is GND
And you will have to play with it. To find what the third one is. Again ...
Guessing it is a light.
The fuse goes on the B+
I would use a 10 Amp Fuse / CB MAX.
Wire size 14 AWG Mil Spec of course.

Thanks Barry....No light involved but I will get the

it is a cigarette style receptcle that is marked 12V.
Thanks for the help. John

Was planning on installing a CD player, but after some consideration, it
looks like CD's are _eventually_ going to go the way of cassette & video
tape . Has anybody installed/integrated an IPOD or IPOD -like MP3
player with your audio panel? I did a little looking on Apples web-site
and didn't find an automobile type/docking station. The preference
would be to install it so that it doesn't have to run solely off it's
own internal batteries. With the form factor of the ipod being so
small, it could be mounted almost anywhere and not necessarily on the
panel itself. Surely somebody has done this?

My Hypervox intercom has a music input. I just installed the
appropriate sized jack, and the iPod works great, running on its own
power. (Of course you don't need the usual RF transmitter if you
just feed the audio into the music input of your intercom.)

I would like to see the discharge graphs to figure my endurance bus time.
My thought is to only spend the extra $$ to save 1.3 pounds after it is

If you haven't yet, stop and think that it might just be more convenient and better
solution afterall to just buy headsets with input plugs and let everyone
listen to the music they want, at the volume they want and to not listen to anything
if they don't want, etc.

| Subject: | New battery option |
--> AeroElectric-List message posted by: "Franz Fux" <franz@lastfrontierheli.com>
Just a heads up for those of you who are building a RV7A with a light
battery up front. I have an 0-360 with a Sensenich prop and I just did
the w&b calculations. It seem like planes with this configuration are
very light in the front. For instance if I have 2 180 lb people up front
and 100 lb luggage in the back, I would be out of the envelope in a low
fuel situation. It seems like if any of you are in the position of still
choosing the battery type, go with a full size heavy battery in front of
the firewall.
Final inspection soon.

Bill I just googled odyssey batteries and I could not find a link to the
factory data sheets. Do you have a link where I could find the data
sheets?
I would like to see the discharge graphs to figure my endurance bus
time.
My thought is to only spend the extra $$ to save 1.3 pounds after it is
flying. Right now saving $30 is smart because there are plenty of other
things I need to buy to finish my bird. The real question is can you
get a
better (cheeper, longer running at my e-bus load) 20AH battery from
Odyssey
than Panasonic?

| Subject: | Re: Ipod (MP3 player) Integration- one solution... |
I like the answer "luckymacy" just posted (using separate audio for each
listener)
But... if that does not appeal to you... here is a less than elegant .. but
cheap and workable... idea
Belkin makes a combo 12vdc charger / audio out adapter. About $30
On one end this is a normal 12 v male lighter plug.. with a stereo mini
socket in its side ... on the other end is a flat Ipod connector.
Audio is routed out of the Ipod .. thru the cable... into the stereo mini
plug .. from there into your aircraft intercom. Granted... with the size of the
lighter plug ... with a stereo mini plug sticking out the side.. the whole
thing is large and an unfortunate tangle of wires.
One solution is to neatly bury all the cords and plugs behind the panel ...
just bringing out the Ipod power/audio output connector which neatly plugs
into the bottom of the Ipod. You now have a connection for stereo audio out
and the 12vdc will constantly power the Ipod.
One other thing.... I love the Ipod.. but... if you want to do anything
other than "set and forget" ... ie: playing a library of various music - then
the
Ipod will need to be close so you can see and fiddle with it... this will
most certainly be a distraction to your flying.
Be careful what you wish for....

Those of you that have installed a TT ADI.
Did you wire it through a switch or straight to the bus.
Just wondering if it needs to be protected while cranking the engine.
Thanks

| Subject: | E-bus Operations With SD-8 |
Gents:
How much current should I expect a nearly-fully-charged 20 amp-hour RG
battery to draw in the event the main alternator gives up the ghost and the
SD-8 carries the E-bus load? I'm planning a Heavy-Duty Endurance/Avionics
bus which would draw a continuous 6 amps, however I could shed an
up-to-2-amp load (the PDA running a moving map) and let it run on its own
battery for a couple hours, and/or turn off the COM radio and transponder
(~2 amps) if battery charging required more than 2 amps or so. But how
would I know? By the E-bus Alternate Feed fuse blowing? I'm not planning
to have an ammeter.
