That wasn't really a question. The question mark referred to it being
one possible answer to your "what bizarre failure". Prepend "how
about" to make it grammatical.

Garmin 196 is powered by 4 AA batteries and will provide ~4 hours of
guidance after the cigarette lighter adapter goes dead. So I could
have no comms, no mode c and no electrical, and still know with some
confidence where I am.

I admit that this is an unlikely set of circumstances as I also carry
a handheld transceiver. OTOH, it never occurred to me to carry a
handheld transponder :=)


I see. After a failure that causes you to lose both of your completely
independent transceivers, and your transponder, you're confident of the
continued flawless operation of your other avionics because your other
avionics consist solely of a battery operated Garmin 196.
