Re: Total electrical failure - (hypothetical)

Replace the fuse on the avionics bus.

I was doing some practice IFR at home last night with my simulator, and
set up for random failures.  First thing that happened was complete
electrical shut down - no radios, no VOR, no Xponder, and it suddenly
occurred to me that I'd never thought through what I would do.  I do
carry backup comm and gps but what if those batteries were also dead,
and I'm in IMC?  I know where I am, but there's no way that I can
continue on course for very long.  There seem to be only 2 options, and
both involve finding VFR (go down if ceilings permit, or head for
nearest VFR laterally), but both involve flying off course/altitude in
cloud without a working transponder.

I'd appreciate some insight from the group.
