It seems that Darryl has consumed so much Koolaid that he's starting to

But you're not running the FAA, the FAA is running the FAA. And the
way they are running it, if Flarm or similar devices were to add ADS-B
out or operate through the ADS-B protocol rather than low-power direct
radio, it would cost them thousands of more dollars, many more amps,
plus interminable certification delays.

It's not happening; Powerflarm is here and now -- you can see the
jets, you get superb collision avoidance with other gliders and
towplanes that install it, and if you add a mode-S transponder the
jets can see you. It makes perfect sense to separate the "in" and
glider-glider box (not certified) from the much more expensive and
certified "out" and "jet sees you" box. I just can't understand the
fuss. Who is drinking the koolaid here?

Amen. The Navworx "simple solution" transceiver draws nearly 1 amp at
12 volts WITHOUT a display, doesn't integrate with any existing
soaring computers, doesn't do glider flight path projection that is
essential to glider-glider collision avoidance and doesn't directly
receive 1090ES data-out signals for the multitude of areas where
that's what you need because the ground station coverage isn't
designed for the places glider fly. Oh, and it costs $2500 but doesn't
include PCAS. So it solves exactly ZERO of the problems that currently
matter to glider pilots and, IMO, is likely to lose out to 1090ES in
the long run because of the aforementioned regulatory requirements.

PowerFlarm plus a Trig 21 is a great way to go because it solves
actual problems we have today and PowerFlarm alone is a pretty good
improvement overall and adequate if you don't fly near a major
commercial airport. Seems simple enough to me.

You can argue all of these points ad nauseum, but your credibility goes
out the window when you say that PowerFlarm is here and now. It has not
been FCC approved, is not available for sale in the US and is not
shipping. When it is, go ahead and push it all you want. In the mean
time, the Navworx box is shipping. Yes, it may not be the ideal
solution; it may not integrate with glide computers; it may draw more
power than you want; it may be too expensive. But it is here and now,
unlike PowerFlarm.
