Jim,

If the instructor
spent more than an hour on showing how the autopilot coupling system
works, then something is wrong.

I think you got that wrong. What could be better than to learn about
autopilot use from an instructor. Would you prefer to have the student
figure it out on his own? Why?

Students aren't encouraged to use
coupled autopilots during training are they?

As I said: The FAA's attitude on that has changed, and rightly so,
IMHO. They adapt to the fact that more and more GA planes have
autopilots, and that many accidents could be prevented if only the
pilots knew how to use them beyond "hold the plane straight and level"
mode. The Kennedy accident comes to mind as a perfect example.

So, to answer your question: Yes, in a current training environment,
students are encouraged to ALSO use coupled autopilots during training,
if the aircraft is so equipped. I said "also", as in: in addition to
hand flying. The FAA requires you to be able to use all eqipment in the
aircraft and the PTS calls for a focus on autopilot usage if the plane
is so equipped.

IFR flying is not a macho contest about who can fly in the soup with
the fewest instruments...

FWIW, here in Germany, single pilot IFR requires an operational
two-axis autopilot. One of the few country-specific regulations here
that make sense to me.
