there's always a compass to fall back on, then! :-)

Large airliners have a great deal of redundancy, and that helps. Contrast
this with things like a G1000 in a small plane, which has no redundancy at
all.

What if the failure isn't in the instrument, but in a sensor? Would that
warrant practice analogous to partial panel, or are there enough
redundant
sensors that it wouldn't be worth it?

Airliners often do have redundant sensors as well.

For those who aren't paying close attention, we've switched mid-paragraph
from redundant airline cockpits to small GA planes with glass panels.

The latter are much riskier than the former.


And since we all know you have never flown or even worked on a 747, your
reference are?
