Y'All,
I very much agree with Vaughn Simons approach to stall recognition. I found
that I could greatly decrease a student's apprehension about the 'stall' by
introducing them to the low power-on oscillating stall series in a
C-150.

From 'clean' level cruise we would reduce power to 1500 rpm and continue
holding altitude at that power
into the stall which usually shows with one wing or the other dropping.
This is corrected not with the yoke
but by using the rudder to raise the wing. We would work the rudder as
needed to raise the wing and break the stall until it required lowering the
nose. The series could be repeated over and over within a 100' altitude
margin.

Try it, you'll love it and never fear the intentional stall again. It is
the unintentional stall that is the killer.
