(USA) NTSB issues recommendations to the FAA and the SSA regarding transponder use in gliders

Good report. I think transponders will be necessary, and a good
thing. Remember, it just makes them required above 10,000' or in the
Class B 30 mile veil, not everywhere - just like everybody else! I
would guess that most (not all, unfortunately) training flights would
be outside the airspace where xponders would be needed.

The cost issue? We pay almost 2K$ for parachutes, glider computers
are over 2K$, etc. It just follows the trend of the sport - it isn't
cheap flying anymore (unless you stay below 10k ft). If you want to
run with the big dogs, etc..

Batteries? I would think the new technology (Nimh, etc) would allow
an Xponder to be powered all day. A non-issue, IMHO.

I just got my PCAS, so I can see the other VFR traffic (that isn't
talking to ATC but has to have a transponder), and a transponder is
next (when I figure out where to stick it in my panel).

Or, as MasterCard would put it:

Transponder and installation: $3000

Fancy battery to power said transponder: $100

Watching the Southwest 737 jinking out of your way as you core a 12
knot thermal just outside Phoenix's Class B airspace: Priceless!
