Mike, believe me:
If you have ever flown half a year with FLARM with lots of gliders
around (e.g contest), you are going to want one NOW *- and you are not
going to have the patience to wait for the better solution that it
possibly available in 2012.

FLARM isnt't going to solve all of the problems, but I am pretty sure
that it would have prevented the incident we are talking about.

FLARM is useless unless everyone is equipped. *That is NOT going to
happen in the US. *Low cost ADS-B could be available tomorrow if the FAA
would certify the units. *NAVWORX and MITRE have working prototypes that
could go into production overnight if we can get the FAA to get off
their but.

We need to get people to send letters to Randy Babbitt to get some top
level attention to this. *It also wouldn't hurt to copy Craig Fuller at
AOPA. *They should be pushing this a LOT more agresively than they have..

An extremely bad outcome of wanting "ADS-B technology" to be deployed
widely would be to end up with a need to mandatory equip with ADS-B
with none of the FLARM-equivalent glider-tuned traffic warnings
produced by the ADS-B receivers, no-compatibility with TCAS in fast
jets and airlines etc. and significant areas where there is no GBT
coverage to provide ADS-R (e.g. for glider on glider traffic awareness
on mountain ridges where there may be a mix of UAT and 1090ES ADS-B
equipped gliders).

This is all extremely early technology, I hope actions by the SSA and
others does not end up heading towards mandatory ADS-B carriage
without these and other issues being addressed. By all means go work
on testing and R&D stuff, but this stuff is far away from being wide
scale deployable in gliders that it is premature to suggest ADS-B as a
solution to practical real world problems like what happened at
Parowan. And I do not feel that overly-involving the federal
government in an attempt to get technology adopted in gliders is a
good idea. The free market should be quite capable of delivering
innovative ADS-B based technology to our cockpits, as has been done by
FLARM (in Europe and elsewhere) and PCAS manufacturers.
