They all repeat the same stupid irrelvent point.

In fact, the key of partial panel appraoch is simple.
If you aren't changing altitude and you aren't changing
heading (either by GPS or compass) then you are straight

is as good (perhaps) better than a needle-ball gauge and
even your average portable is a whole lot better than the
whiskey compass.
