This is news to me,

So in IFR in dense cloud, the AH starts going funny,
one still x-checks against the heading indicator and
the altimeter/rate of descent.
Finally there's the magnetic compass that is fool-
proof, (not idiot proof-Bertie couldn't find it ;-).
For rate of descent, the power setting vs, KIAS gives
a fair good idea of the rate of descent.

That all works for a 1/2 ass pilot, however if the cabin
pressure had a slow leak, and the pilot slowly looses
mental faculties, (Bertie is a typical example), that
could lead to pilot confusion.
