I will go with that. With the old engines it was always `when` it would
stop, never `if`. I have always flown base leg within gliding dictance of
the field and closed the throttle as I turned onto finals. Downwind, base
leg and finals are pretty much indistinguishable with me. A sort of squarish

Malcolm,
Could you provide the name of "a Senior Aviation Specialist at the EAA" that told
you that? I'd like to confirm your understanding with him/her.
I'd like to be able to instruct (I'm a CFI-SP) in our Rans S6 but don't think that
is allowed except for my co-owners. That has been my understanding for eons.

Thom, Malcolm, et al, Who cares what "a Senior Aviation Specialist at the
EAA" says? He/she can say anything, whether well meaning or not, and it
means nothing, it's just their opinion.To try and track this down again, I
called the Light Sport Branch in OK city. I proposed Dana's conjecture, "I
charge $120 an hour for my instruction, I supply the plane for free". Would
that be legal?
Answer: "It's a gray area that would be decided by your local FSDO". "The
FAA does not want to become involved in setting compensation rates". As an
aside, these people aren't stupid, if an instructor is charging far above
the local rate, but claiming the aircraft is provided for free, they're
going to figure that some portion of the cost is going to be used to support
the aircraft. This was the general thrust of the comments.
So, sorry guys and gals, I can't give you the definitive answer, but your
local FSDO can. Call them for the answer, they're the folks who will start
the enforcement action against you. I don't think the, "a Senior Aviation
Specialist at the EAA told me it was okay" defense is going to hold much
water if they do.

Subject: | 9-volt DC Power for a Handheld Radio? |
Kolb Friends -
I have a Sporty's-200 handheld radio that I use occasionally in my Kolb.
Up to now, I have always operated it using its own battery power.
Recently, I obtained a power cord to power the radio from an external DC
source. The cord plugs into the 12v DC cigar plug receptacle in my
Mark-III, and the other end has a small plug jack that plugs into the
radio. I figure this will help save the batteries in the radio, if I
power it from the aircraft 12v power system.
Here's my question: The plug jack on the radio says "9vDC" on it. Nine
volts?!
The eight double-A batteries that make up the battery pack (at a volt
and a half each) totals 12 volts, so it's inconsistent why would the
markings on the radio would say 9 volts.
Will it hurt this radio to run 12v DC into it from the external plug-in
power source? (This individual circuit is fused at 3 amps.)
Hoping to gain some knowledge before I fly it like this ...
Thanks -

Hi Dennis,
I'd guess Sporty's has the right adapter. Don't wanna let the
'smoke' out! Some electronics are tolerant of the overvoltage, others
aren't. Cell phones in particular can have pretty sophisticated
adapters, work on 12/24V as an example.

Got an answer for your radio power supply - I
believe it was Target used to sell a voltage
regulator that plugged into a cigar lighter - it
had a switch on it to set it to different output
voltages commonly used by electronic devices. A
friend got his first then I got one for my plane
to add protection for the radio. It worked good.

Subject: | 9-volt DC Power for a Handheld Radio? |
Dennis,
Yes, you do run the chance of frying something. 99.9% of all AA rechargable
batteries are actually 1.2 volts, not 1.5 volts like Duracells. I don't know
why they do that, it's dumb if you ask me.
If you put a multimeter across the radio's battery pack, you see pretty close
to;
8 batteries x 1.2v = 9.6 volts (not 12v, like you're thinking)
BTW, Radio Shack sells a variable voltage aux. power, that plugs into your cigarette
plug hole.
It comes with a handful of interchangable plugs. If I remember correctly, it offers
3v, 6v, 9v,& 12v.
Yes, you can ruin something, even if you are only a fraction of a volt away from
what's correct. I plugged my 3.4 volt Nokia phone into a 3.6 volts supply.
Fried that sucker dead, dead, dead! It became a paperweight real quick.
Last tip, I promise. If anyone actually needs real, genuine, bonafide, full
1.5 volt NiMH rechargable batteries, you can get them on eBay somewhere. Just
do a 1.5 volt AA search. They're not those dopey 1.2 volt slugs, they ACT like
Duracells!! I got a couple dozen of them to run my digital camera. That turkey
eats batteries like the government had a bail-out offer on 'em.

Subject: | Re: Instructing in a Kolb |
Rick,
I think you have said it best. It is a gray area and it would depend on who
ever wants to enforce the rules as they see them. I received an email from
NAFI today that said " If you are providing the aircraft and the instructio
n, it will be considered a package." and would not be allowed. Timm Bogenha
gen from the EAA said that it does not matter who provides the airplane. I'
ll be darned if I can read any of this into what it actually says in 91.319
. The bottom line is that instructing and receiving compensation for instru
cting in an experimental appears to be just fine with big brother. The stud
ent appears to be able to provide the airplane, either their own, or a club
aircraft, or one borrowed, stolen, or otherwise acquirred, but just not re
nted. The issue for debate with big brother would seem to be whether I'm le
tting the student use my airplane out of the goodness of my heart because t
here are no other LSAs available in the area, or am I really receiving rent
through my instructon fees for the use of the airplane. If the hourly inst
ruction fee was reasonably inline with the norm, and the same rate was char
ged to students whether in my airplane or their own airplane, then I would
guess you could make an argument that you were within the intent of the FAR
. However, as you have pointed out, it is ultimately up to the FSDO should
they choose to get involved. I know in my part of PA getting sport pilot in
struction is next to impossible, so I plan to pursue this a little more. I'
ll keep you posted and thanks again for the inputs.

Subject: | Re: 9-volt DC Power for a Handheld Radio? |
Dennis:
Here are the specs for power input for the SP200:
Battery Pack Power
Nicad Battery Pack 9.6 VDC / 600 mAH
Alkaline Battery Pack 12.0 VDC (8 AA batteries x 1.5 VDC each)
Nicad Bat is 9.6VDC and the Alky Bat Pack is 12.0VDC.
The way I interpret that is the radio will operate on 12.0VDC or 9.6VDC.
Most aviation radios and other avionics have a pretty wide spread on operat
ing voltage.
If it was my radio, I'd operate it on 12VDC. 12VDC coming out of your on b
oard aircraft battery is the same as 12vdc coming out of 8 AA bats.
My Icom A3 is 12 to 15VDC. 18VDC will cause the LCD to flash 18VDC Overvol
tage.
I'd contact Sporty's. Find out what voltage range is published for the SP2
00. I bet it is 9.6 to 12 VDC, or maybe 15VDC, but you will have to contac
t the experts to verify.
Sporty's has a multivoltage transformer for your radio but they want $75.00
for it.

Radio Shack's version is much better than this one, and I think they give you

I don't know about the 9V - 12V issue but be very careful to unplug your
equipment while cranking or powering off your airplane. I have a King
KLX100 that I have fried twice by cranking or turning off the ignition
while the radio is plugged into the system. Both times King fixed the
power circuit for a nominal charge but now they talk about a major
charge.
Most cars have circuit that interrupts power to radios while cranking.
Wish my plane does.

Ricks right on the cranking of the engine with electronics on. The transient voltages
spikes from the starter motor can be several hundred volts, bad news for
radio's. Your hand held radio probably has a built in voltage regulator.
But be sure to check your manual or Sporty's to verify this before trying it.

Dennis,
>From the JD-200 manual:
Cigarette Lighter Power Adapter/Nicad Battery Charger (#8634A)
Allows the JD-200 to be powered externally from a cigarette lighter in
aircraft with 12,
24 or 28 Volt electrical systems (accepts input voltage of 10 to 30 Volts
DC). Plugs into
the side of the JD-200, which allows the unit to be powered with or without
a battery
pack attached. Also charges the optional Nicad Battery Pack (#8631A). Safe
for use
with the Alkaline Battery Pack. Power cord measures 6 ft. long.
Note: Bold print done by me.
If you have this adapter you can carefully open it up and look inside. I'll
bet you a quarter that all you'll find is a small resistor and an LED. That
s
all there was in the adapter for my Lowrance 2000 GPS and my Icom radio. Al
l
voltage regulation is done internally to the device not in the adapter. Giv
e
Sporty's a call and I'll bet they tell you the same thing.
It's a liability issue for the manufacturer. They're selling you a backup
radio and the legal bills would just sky rocket if an adapter fried your
radio when you needed it in an emergency.
If Sporty's tells you it is as I think, you can save some money and panel
space by foregoing the cigarette lighter socket. Find any old charger for
any appliance that has the right diameter and length of plug that goes in
the side of the radio. These can be found at DAV, Goodwill, etc for fifty
cents to a dollar. Cut the transformer off and wire it up through a fuse
directly into the airplane.
Just make sure you know:
1. The polarity of the socket
2. Which wire goes to which part of the plug

Subject: | 9-volt DC Power for a Handheld Radio? |
If it was my radio, I'd operate it on 12VDC. 12VDC coming out of your on
board aircraft battery is the same as 12vdc coming out of 8 AA bats.
>>>>>>>>>>>>>>>>>
12 v is 12 v,,,,, however on my 912 the charging system runs at 13.8
v----------- call sporty and see what they recommend.

Most cars have circuit that interrupts power to radios while cranking. Wish
my plane does.

Rick, my main switch for my radio's etc,,,, is a double throw
on off on switch
My starter switch does not get power until the radio's etc are off.
