An interesting trial flight attempt...

How many charge/discharge cycles do they figure?

More than your PDA ;-)
There's more detail on the Lange web site under FAQs

Hope that helps !
Best Regards, Dave

Did anyone figured out the cost per, say, 1000ft of altitude, giving
the battery replacement cost, charging cost, engine maintainance etc?
It would be interesting to see a comparisom between electric glider,
motorgliders, aerotows and winch tows as for the overall cost per
1000ft of altitude.

You could get 200 US glider pilots to chip in $500 on something that
won't increase their L/D? You must be quite a salesman 8^)

I for one, will be more than happy to chip in $500 for something that
will significantly increase safety. Most of us spend up to about $1000
on parachutes which we probably never use, so why not a Flarm like
device? I hope someone will either license the Flarm or produce
something similar, and then make it mandatory... Till then we will
continue average at least one mid air per year in the US...

I gave a short presentation on FLARM at the 2005 SSA convention, and
have tried to generate some interest in it. Very few people have had any
interest in it, unlike the huge response in Europe. I think the
difference is we don't have nearly the mid-air collision problem that
they do in the Alps, Pyrenees, and other places. Their airspace can be
far denser with gliders than ours, even including the White mountains
and the ridge-runners along the Alleghenies, and as a result, they run
into each other more frequently.

The poor response I get may be reasonable: personally, I think a
transponder is a better value at, say, $2000, than FLARM at $620Euro
(US$745). My experience is the glider that is likely to run into me is
the one I'm thermalling with and already know about. Except for
contests, I see more airplanes en route than gliders.

Even so, I hope people will pursue it. There are mitigating features;
for example, the FLARM will log a flight in IGC format, though it's not
secure at this point. If that happened, it wouldn't cost much more than
just an IGC logger. Busy clubs could benefit from it's use with a ground
station and automatic logging of tows and club glider use by it's
members, and there are other applications under way.

Besides technical people, I think we need some good lawyers that can
analyze the liability situation, then create a means to license or
otherwise acquire the technology from FLARM that would ease the concerns
of the FLARM developers.

I'd be willing to chip in at least $200 for starters.

I also suspect that FLARM won't do much to help where I'm most concerned
about a collision with another glider, the ridge running down the White
and Inyo mountains near the CA/NV border. FLARM advertises an effective
range of 2-3 km, or 1 to 1.5 nm. Given a head-on approach between two
gliders, each running at a TAS of 150 knots, you'll be lucky to get 10
seconds of warning. Might work for an ex-fighter pilot, but that's not
much time for someone like me...

But in the case of running the Whites, there's a radio procedure in place.

Any idea how universally adopted (or not) it is?

At the risk of further hijacking the thread , may I suggest pilots not to
turn off their transponders when flying over the white mountains? Some of us
nowadays are equipped with low cost TPAS and would like to receive your
transponder signal...

Did anyone figured out the cost....

Are you mad ? If we knew the real cost we'd never fly !
Especially if our spouses knew the real cost !
See ya, Dave

Actually, I may try to convince wife it may be cheaper on the long run
to buy a motorglider (or electric glider) then pay for aerotows, but I
need numbers...

Actually, it's probably best to forget about using numbers, as that implies
that you will try to use logic and fact . . . and we all know *that* won't
work.

Naw, overall it's probably more expensive to operate a self-launch. But that
extra money buys amazing versatility, the ability to go where pure gliders
can't (or at least not without a retrieve), And the convenience of always
having your "tow plane" tucked away conveniently along for the ride.

Purist?? Hawks and eagles self-launch!

I did a very rough analysis of another glider instrument, probable
market size, and necessary pricing he

The good thing about the FLARM is that the design/function is resolved
so your costs are reduced there. But then you still have the risks of
distribution and, implicit, support.
