FWIW, Cessna's training specifically states that it's not recommended
to pull breakers to simulate failures.

It really boils down to finding the single points of failure. In the
Cessna piston G1000 package the AHARS and ADC are the only single
boxes that matter in the system. The GIAs are duplicated (giving you
2 independent NAV/COMs and 2 GPS units), the engine analyzer and
transponder are a nuisance to lose at best, and the screens are
duplicated and have manual and automatic failover. With all the
redundancy there really aren't many failure modes I can think of which
will leave you with nothing at all. PFD and master electric failure
at the same time? Even if the AHARS kicks out you have the backup AI
and both screens with MFD, wet compass, and inset maps for heading.
ADC kicks out you lose your speed tape, TAS, and altitude display.
Standby ASI and altimeter, move along, nothing to see here.

Perhaps during training some of the partial panel training could be
conducted in steam gauge aircraft or simulators which IMHO would be
better than attempting to concoct multiple system failures in
combinations which wouldn't appear for the 1st time in IMC?

I haven't looked, but are there CB that can be pulled to
fail components of the G1000 package?
