FLARM Statistics

Ballistic Recovery Chutes would primarily be an advantage in a low level
collision (i.e. in a traffic pattern). Are there any statistics on glider
mid-airs that can shed some light on where most of the danger is?

I don't know what the right answer is. Here in the US, there is a lot
more power traffic than in Europe. Unless you are flying in contests or
in high glider traffic areas, I suspect that the biggest risk is not
other gliders, but power traffic.

It's very frustrating that the FAA doesn't accelerate the deployment of
ADSB here in the US. Then everyone could focus on developing cost
effective technology that will cover all traffic.

In the mean time, the best investment might be a ballistic recovery
chute.

In the Minden collision, the regular parachute worked just fine, and if
he'd had an operating transponder, he'd likely not needed the parachute at
all.

A transponder and a TPAS unit will give you most of what you'd get from
having an ADSB unit in your cockpit, more cheaply than an ADSB unit (or a
ballistic parachute), and you can have it now. Powered traffic is already
flying with transponders, so you don't have to wait for the rest of the
fleet to buy into the idea. ADSB still doesn't protect you from aircraft
that don't have them, and I don't think they will be any cheaper than a
transponder. So, if powered traffic is your concern, I think there is
decent solution.

A ballistic recovery chute has some advantages, of course, but perhaps not
in the typical collision which is usually high enough that a conscious
pilot has time to get out. The problem is they are expensive to retrofit
to most gliders, and then you have an untested system.
