Especially for new. A second one is a negligible cost increase. To have
a transponder fail enroute, is a real problem these days. When mine was
giving me grief it really messed up my trip. I would put a second one in
my seneca but I will soon be ordering a new plane and it will have dual
transponders. I don't fly vfr when on lnog trips.

Now for new aircraft, dual transponders are the way to go.


Perhaps I am missing something obvious, but why would you need (or want) two
transponders for new aircraft?
