Default Interesting thing with transponders

Jason,

Thanks for the explanation; that all makes sense. It would seem that
if the discrete code becomes a problem in a wave window, then a common
code (like the Reno 0440 code) would be one way for ATC to handle it -
that would still give TCAS protection for airliners, bizjets, etc.

It looks like there was some confusion about military aircraft
transponder use - bottom line: in common use (civilian and military)
airspace, military aircraft are handled just like civilian aircraft
with transponders - if IFR they are talking to center and get normal
IFR handling, if VFR (say in a MOA running low altitude intercepts)
then they are like other VFR traffic with transponders (and many with
TCAS and interrogators): They may not be talking to center (they will
be on their own freq) so having a TPAS in a glider will definitely
help, and a transponder in the glider may help the military aircraft
detect and avoid the glider.

Good conversation, all in all, IMHO.

Cheers,

KIrk
