Subject: | Mono Isolation Amp - Where to get circuit board? |
I am adding a second radio to a plane that has no room for a full audio panel without
making a whole new panel. I am going to route two coms and one marker
beacon to the intercom. I have speced out the switched and dome a wiring diagram.
I looked at the Isolation Amp at the AeroElectric web site. However, under
parts, I don't see where I can order the circuit board to make the amp (part
no 9009-301-2A).
Where do I get one?

You can't find v14 on eBay for anywhere near $20. The lowest I found was $80 +
shipping (or up for bids). Good comment about the extra symbols needed though.
Sort of like buying a car and then finding out it needs tires to be able to drive.

I have written about this extensively on this list and IMHO--
1) Aeroleds is to be saluted for making their led landing and taxi light.
There will be many good led products. I have said to interested parties that any
led product you can now buy becomes obsolete in the time it takes to develop
a product. The design engineer's current nightmare!
The best LED product efficiency is nearly 100 lumens/watt and soon will be 150
lumens/watt (7X better than halogens).
For experimenters, I recommend you check--

Cheap prices, fast shipping. Amazing stuff. As for LED landing lights, you could
just tape together a few of their big flashlights and do the job cheaply. Check
their 20W and 50W leds!!!! Awesome.
I still have a couple LED technical notes on my website:

#2 wire it is...
Response received from Kelly Aerospace:
The only information we have is for testing the starters in a "no load" condition
on our test bench which does not correlate to the current draw under load with
the starter turning the engine. I recall from past experiences that the current
draw during cranking would be 250 - 350 amps under normal conditions, obviously
higher at the initial onset of the start, then tapering off as the engine
rotates.
I think the best idea would be to review a service manual for a production aircraft
and use its electrical system schematic as a guide. Any Piper PA-235 Commanche
or PA-23-250 Aztec series might be good examples to consider. Each of them
run a Lycoming 540 engine.

Eric,
Interesting website. A venerable oasis for flashlight builders. For
anyone thinking about building LED flashlights I saw you can now buy a
nice 4" job at Harbor Freight for < $5 now. Don't waste your time
building them unless you are simply interested a project.

I think V14 is the latest release, and availability will vary from time to
time on Ebay. I just checked my buying history, I paid 99cents plus $5.75
shipping for a total of $6.74 for brand new TurboCad Designer 14. Previous
to that I won a version 11 for $13 plus shipping but was refunded because
they didn't actually have it in stock. I just looked now and you're right
there's none in this price range now, but keep looking, it can happen.
I'm not sure the versions change much from year to year and Bob had
mentioned that anything above a version 7-8-9 (I don't remember which) will
work fine for our purposes.
Keep looking.

Subject: | Voltage drop under load |
I noticed today that my voltage would drop from about 14.5 volts down to
13.3 volts when I turned all my lights on. That is two 100W landing, two
100W taxi, position, and strobe lights.
I made sure that I had plenty of rpm to be certain that the alternator was
putting out its max. The alternator is rated at 55A.
Is it possible that I am pulling more amps than the alternator can handle?
Is the drop of voltage an indicator of this?
What should be the size of the B lead wire for a 55A alternator?
Thanks,
Bill B

I purchased the AeroSun 800 for my weight shift trike nose landing light. Flying
sport pilot I don't fly at night, but do land in civil twilight.
The product is well made, very sturdy, bright as hell, easy to wire up. My single
light is controlled with one switch, as either light or wig-wag/flasher.
I talked to the folks at Aerosun before purchase. They even sent me to Aircraft
Spruce for a lesser price than direct from them.

Yes, I could build my own LED light but for the $$ their unit is very nice, works
well. Whatever floats your boat.
Fly safe,
Mike

Subject: | Re: Voltage drop under load |
Yes voltage starts to sag as the alternator output starts to lag demand.
Quick math suggests that your alternator is working properly. (100 watts
divided by 13.3 volts is about 7.5 amps per 100 watt load) My alternator
can handle all loads but the voltage will drop a bit if I pull the
throttle to idle on approach. No big deal if the battery helps out for a
few dozen seconds on final approach. In cruise my taxi lights wig wag
which halves the current draw.

If the ALT breaker pops (and it will in milliseconds in an OV situation)
wouldn't that also kill the low voltage warning and defeat the purpose
of it?

Subject: | Re: Blue Mountain EFIS |
I too am a BMA customer with a G4 lite plus. I have gone through the same problems
that others have mentioned. looking back I can remember several occasions
that I wanted to rip out the unit and drive over it with my truck.
Nothing worked as advertised, Software was incomplete, Features were missing etc...
It has been over a year now and with the updates that have been released
it has become quite useful. Right now as it stands I have a very stable and informative
EFIS. The autopilot is now functional and has good integration with
external device as the Sl30 and GNS430. I now trust it for my primary IFR but
i also have backup gauges. I can not find a single EFIS system out there that
I would trust solely for IFR without some backup anyway.
Trust me.. I looked at every EFIS company out there. I looked at the features
and performance and still I stayed with the Blue Mountain.
It has been a love hate relationship with them. Greg is not the best business
manager I have ever dealt with. He really screwed the pooch with the roll out
of the G4 line. Releasing it before it was fully tested or the software was fully
implemented would not have been my first choice. But I do not know the full
story or what his game plan was.
I know he was forced to put out the G4 line as the design for the G3 had too many
limitations.
In the last six months I have seen a huge change in the product and his efforts
to release quality updates. Every update is carefully tested and refined and
shows major improvements. The first six months the releases were just to add
the functionality he promised it was to have and the last six months the updates
have refined small issues. Over all I now have a unit that is 95.5% of what
was first promised.
I have not found any EFIS that has everything that I would like to have.
Dynon has a good unit but the decision not to support 3rd party autopilots is a
Big turn off for me. BMA has their own autopilot that now works very very good
but they still chose to allow integration with other autopilots. Bravo!!
Advance's EFIS has a really complicated GUI.
BMA is a small company. Releasing the G4 line before it was fully ready might have
been a financial one but I am happy that they stuck with it and now they can
focus on marketing a product that can hold it's own against any other.
I find it really ironic that I am defending them after all this time. But I really
like the design and simplicity of the design now. I would defiantly put
another one in my next plane.

Subject: | Dimmer hookup to Avionics |
I know some (ALL?) of you folks know a lot more about this than I do, and rather
than take a chance of frying something, I'm going to ask here.
I am hooking up several of the AeroElectric dimmer boards units Bob used to sell
on the AEC site to my panel, (Now B&C sells them as DIM15-14's) and one of them
is to be used for dimming the internal lighting on my MAC 1700 (Really a KX-170A)
radio, and a King KT-76 transponder.
I want to make sure I get the hookups right. I hate letting the smoke out of expensive
"stuff".
On the pre-wired harness I bought (years ago) with the NavCom, it had one wire
labeled "Lighting" and another yellow wire labeled "Dimmer".
I don't want to just start trying things, so can any of you tell me which of those
wires I need to hook to the output of the dimmer unit?
Does one of these wires from the radio go to +14VDC, and the other to the dimmer
board output?
I have tested the dimmers and they work fine with light bulbs, etc., but I don't
want to fry anything internally in the radio(s).
Thanks in advance.

Stan, thanks for the reply. How are you coming on the lights?
I have just started messing around with them and was wondering if anyone
else had
come up with anything.
I agree about the charge for restocking for something you don't know will be
as
advertised.
Dan,
I did some experiments about a year ago and then again recently. I'm using
Luxeon K2s which are one watt and produce about 80 lumen. Later model LEDs
produce more lumen per watt.
I have some optics for them that focus the light nicely but it would require
6 or 8 to adequately illuminate in front of the plane. Also, mounting them
and heat sinking are problems to be solved. The number of LEDs in series on
a single power supply has to be carefully studied to make sure you don't over
or under voltage them too much. With the Luxeon K2s, I can have only 4 on a
single 12v power supply.
It appears the aeroleds.com guys have solved the problems and the best
solution may be to wait for them (or someone else) to work out the bugs. ACS
sells the AeroSun 800 for $155 each. My estimate is that you will have to invest
about $100-120 to develop a similar light yourself, so their price is not
too bad.
If the AeroSun 800 produces sufficient light, then I believe that is the
best current option for LED-based landing/taxi lighting.
