Two points on this evolving thread:

Sean: If you do get files and a program that can analyze them in real
time, searching for close call midairs would be useful as well as
suspcious circling well above the rest of the pack. Also, extremely
low flying. OK, nobody wants to put in the "hard deck" I've been
suggesting for years, but at least we could watch those 200' saves and
think about them.

Weather in the cockpit: This is a different kind of question than
artificial horizons. It's a competitive issue not a safety issue. The
RC has kept the ban on weather data in the cockpit only for cost
reasons -- didn't want everyone to feel they needed another toy to
compete -- and because we poll it every two years or so and the vast
majority say they want to keep the ban.

It's pretty clear that like GPS, costs will continue to come down,
most pilots will eventually have some sort of weather feed in their
recreational flying, and a ban will become anachronistic. There are
also some obvious potential safety advantages to having weather data.
(For the moment it strikes me the radar loop is useful when storms are
around. I'd really like to have the 1 km visible satellite loop, but
haven't found any reasonably priced system that gets that.)

When a solid majority starts answering poll questions with "let us
bring weather data along for contests," I don't think there will be
much reason to oppose it. We could think about allowing some kinds of
equipment and not others -- yes to aviation models such as Garmin, no
to unrestricted satellite based internet -- or class specific
limitations -- yes in open and 18 where cost is no object already, no
in club class.

That's also a signal to manufacturers. If however manufacturers came
up with weather screens at reasonable extra cost, I don't think they
would be banned forever.

So, if you want it, just start making noise.
