Hmm... the only glider I ever flew in didn't have anything resembling

You might be surprised at the sophistication of a modern glider (not
some stone age beat up trainer). My 20 year old LS6 has two
independent GPSs, moving map, glide computer, electric varios with
audio, radio, ELT, dual redundant separate battery systems, etc.

Many of my friends have transponders and/or TPAS's in theirs.

Nice to have on those long XC flights.
