Jay,

I think you missed my point.

Like I said originally to you in my original post, you ignore certain
sensations (inner ear like you say) but you DO NOT ignore the seat of
the pants sensation. Two different beasts but still sensations.

Mx blanket statement is flat out wrong. I only brought out the vacuum
failure as an extreme example, but even with a full working compliment
of instruments, you still need to listen to your sensations.

Read my ILS rational, where you feel the applied power to capture the
glide slope. If you don't feel it in the seat of your pants, you got
a bigger issue. If you are above the glide slope, and you reduce
power, the lack of pressure in your butt should happen, but if the
opposite happens, you have a problem.

Good example, though not likely, but very possible is having the trim
set in the nose down position rather then nose up. Apply power and
instead of maintaining level altitude, you just accelerated downhill
and you wouldn't get that firm seat of the pants feeling. The
building airspeed and the ABSENCE of an expected seat of the pants
feeling doesn't bode well. This would be an extreme example, but very
pluasible.

Remember, that the above sensations helps CONFIRM the instruments, NOT
the other way around.

but to state that you don't place absolute trust in
your instruments in IMC does the students on this group a disservice.

You can't. If you do that, you miss the whole point. It's a
combination that makes it all work. If you put 100 percent faith in
instruments and ignore what I am describing above, then you are
failing to recognize instrumentation or airplane setting errors, and
that will lead to a not so good ending.

It's a combination of instruments AND what you feel in the seat of
your pants (NOT your inner ear feelings) that makes a difference
between landing at minimums or butching up an approach.

Now, of course, if you want to talk about flying by the seat of your pants
after your vacuum pump goes T.U. in IMC, well, that's another thread.

Nope it is not, I flew my partial panel Friday the very same way if I
had full instrumentation. I just had less gauges to monitor :-)

Again, go up with an IA rated pilot, see what the real deal is all
about. That hood just doesn't do it any justice, nor will any MSFS
desktop simulator do it.

If you have not seen my video, go to http://www.youtube.com/watch?v=RCvDb3mCAf8
and then watch it at 1:39. Look at the cowling, and it was straight
and level relative to the camera, but in reality, I was in a climbing
right turn. You feel that climb in the seat of your pants which is
verified with your attitude indicator (when it works!).

In my case, I verified the VSI reading with the feeling in my rear
end. This has nothing to do with inner ear balance which is what you
need to ignore. Had I not felt that climb in my rear end, then I got
something big time wrong with the plane that I need to reconcile,
whether it be trim, or power or something.else like picking up icing
affecting my power performance.

Bottom line, in IMC your seat of pants sensation will save your butt,
but you got to use it by listening to what it's telling you, or more
importantly NOT telling you. (seat of the pants sensation)
