I don't have any numbers but I heard of many more midairs between two
gliders or gliders with tow planes than between gliders and other
powered aircrafts. I'm afraid the White Mountains in Nevada are a
midair waiting to happen. On a good weekend you can have 20-50 gliders
flying in a very narrow band in both directions. It is very difficult,
almost impossible, to spot on time a glider flying straight and level
at closing speeds of over 200 knots, unless you know exactly when and
where to look. Remember, the moving targets we often spot easily are
not the threat, it is the one which don't move on the canopy which will
hit us. If we equip all gliders and tow planes with Flarm you will
significantly reduce midairs, as it has been proved in Europe and OZ.
One would wish that one of the local US manufactures of glider avionics
or an entrepreneur would have try to license flarm in US. If it is
possible to manufacture and sell TPAS like equipments in the US without
liability concerns, it should be possible to sell Flarms.

Just my humble opinion,

Ramy

Another interesting question for the US is what percentage of mid-airs are
between two gliders vs. between a glider and a powered aircraft.

Does anyone know of a source of any statistics that
might indicate the effectiveness or otherwise of FLARM
in reducing the rate collisions between FLARM fitted
gliders in those European countries in which it is
in widespread use?

Thanks in advance.
