Guys-
I think you might want to check out www.aveoengineering.com
They are releasing this as a standard feature in a DFD Skyway and
TrafficCom/TransCom units, and the cost of these units is very low
compared to Garmin. They don't have to pay for all of Garmin's
marketing... they sell through word of mouth in the aviation
community.

The reason your previous estimates were around $10k was that you were
looking at a Garmin solution. Garmin isn't the only game in town.
Actually, sometimes other companies can come in with a new technology
that is leaps over the competition. I believe that might be the case
here with their Digital Flight Deck (DFD). It has XM Weather, XM
Radio, Traffic depiction, WAAS GPS, etc. etc. Plus, the Aveo menus
are simple to operate... not a click here, twist this, then this, then
click here, then confirm, etc. like on the Garmins.

Give them a look. I think you'll be pleasantly surprised at how low
cost and highly functional they are. And remember, they build
military grade solutions at Aveo! If it can work in a jet fighter...
it can work in a C150 :-)

Cheers,
MrBizi

But the ADS-B requirement is achievable,

Complete (In and OUT) implementation of ADS-B is achievable too, and
it would be significantly more useful than what is currently proposed.
But, that isn't the issue. It's a matter of cost verses performance.
What significant benefits does the current FAA proposal provide to
light GA operations that might conceivably justify such a significant
investment. Consider it might cost as much as 50% of the value to
equip a C-150 with ADS-B, and significantly impact it's already
marginal useful load number.

it is possible to put this
type of equipment on your aircraft (I would even look forward to it),

I would look forward to it also if it were the full ADS-B
implementation. Then the pilot would received useful information.
There's even a chance that the position of military training flights
might even be depicted then. But the FAA's proposal is for solely
your aircraft to transmit its GPS coordinates and transponder S code
to ATC at a cost to ALL aircraft owners of around $10,000.00. There
is no data up-link to the cockpit, no WX, nor traffic depiction at
all.
