absolutely....installing a transponder doesn't require any documentation if
it's in a experimental other than maybe a logbook entry and a new
wt/bal......BUT turning it on does!
Any Transponder equipped aircraft has to have a static system test and be
signed off by an approved avionics repair station prior to use....these all
then can be monitored by ATC... without this what is to prevent a
transponder equipped glider flying at 10,000' and reporting to ATC that he
is actually at 9000' and directly in line with the flight path of a 747!
Also.....consider, a Transponder equipped aircraft is also REQUIRED to have
the transponder ON and reporting at all times from wheels up to wheels
down......not just as I have heard many glider pilots saying they "only use"
the transponder when they are flying at or near areas of high traffic....
think about this....

Very nice update. One missing issue: installation legalities. I konw
some pilots have gotten 337s. I know that many have not. Do we really
need a 337? What reg says so (I looked to no avail)? Why, for example,
would a transponder need a 337 but a radio does not? What is, really,
required to legally install a transponder?

I've skirted around the legalities, because it's a confusing issue to
me, too. I would like to address it, however, so if someone
knowledgeable can provide me with info on it, or point to a good
source (documents or person(s)), I'll be glad to add a section on it.

Otherwise, we'll have to wait until I can dig it out myself!
