Without getting into a whole magilla concerning right and wrong,
simply let me say that in my opinion physical sensation should never,
and I repeat it again so that there's NO mistake....NEVER be used to
verify or augment an instrument reading. In my opinion, this is what
proper scan technique is all about. You verify instruments CONSTANTLY
using other instruments, right on down to primary panel if necessary,
but in my opinion, the basic concept of ignoring physical cues and
sensations while on instruments is a sound principle ans should be
followed to the letter.

I won't argue with a single word of that.
But...
That doesn't make physical sensations irrelevent or unimportant. In
fact, it is the MISLEADING sensations that are very important in the
sense that, if you don't have significant experience "playing over"
them, one typically ends up dead (in real life). Sitting on your lazy
boy, those sensations don't happen - you always feel "coordinated" - you
don't get disoriented, you don't experience vertigo - which makes flying
in simulated IMC stupid easy compared to real life.
And, I would argue that _no_ _ammount_ of desktop simulation will _ever_
prepare you for the assult on your senses that can happen when things
aren't going well in real life soup.
One may think that one can handle real IMC based on desktop experience -
but without realizing just how difficult it is to ignore your inner ear
screaming lies at you, one doesn't really have any idea what flying real
IMC is like - I would bet that an experienced "sim only" pilot would
pull the wings off in less than 3 minutes in real life.
I believe you and I are in complete agreement. Perhaps something being
misread.
The understanding of sensations and how they interact with the IFR
experience is of paramount importance. In fact, a lack of this
understanding can get you killed quicker than anything else I can think
of at the moment.
Where I was referring to the sensations issue was directly concerned
with one pilot who commented that verifying an instrument reading with a
physical sensation was important. My point was that instrument
verification should be done against other instruments with the EXCLUSION
of physical sensation from that equation.
When I was a kid, I was spun to dizzy, and
then staggered when I tried to walk. IIRC it
took a concentrated focus on some point to
sustain balance, which is me in VFR, but that
doesn't work in a fog.
Another thing I noticed is flying VFR with a lot
of turbulence, (especially with towering cumulus)
screwed my inner ear.
(That is my weakness).
I was very lucky that after just a couple of hours,
my flight instructor got me going on IFR.
He knew I had a basic handle on geometry and
algebra so he was the type to promote the advance
early on in instruction.

I tend to keep things on the basic level with students. It helps to hide
my shortcomings :-)

After a few hours, my instructor had me doing shallow
(30's), medium (45's) and steep (60's) turns and would
critcize me because I focused on the VFR horizon and
he'd smirk and point to the Indescent Indicator showing
a 50'/per minute loss, and the IAS loss of energy and
my off-center-ball, so my turn performance was gauged
by instruments.
Obviously, I should have pulled a bit more elevator,
put on some RPM, and applied more rudder, so that's
what I did via instruments, and that's in a well done
bank at 60 degs even when VFR is available.

I'm the reverse ytpe of instructor. Initially I like students to get
their heads outside the airplane and discover nose attitudes (LF;Climb;
glides) THEN after they have a good understanding of these nose
attitudes I get them to cross check these attitudes with the panel.
Different strokes for different folks

I was a Professional teacher for awhile, and so
understand the attitude. I was very lucky to get
an Flight Instructor that was A+, never made a
mistake. He had me doing what you say, using
horizon, but then gauged the accuracy of turns
based on instruments, I thought that was fair,
then pointed out my weaknesses when I was
using pure VFR, such as uncentered ball as I
entered the bank going from level wings to 30,
45,60 bank.
It was the change in bank that I had to work on.

We did about 5 hours of night flying together,
he didn't say much by that time, except the odd
ancedote. It was very pleasant.
