Copied from the post you are answering;

pressure application
quality."

Let me add to this, that once stabilized in the turn, it is not only
possible, but advisable to monitor coordination by using physical cues
instead of watching the ball. The quality of that physical monitoring will
include a visual cue on the nose, and the physical cues sensed by the body.
The overall quality of this process will be dictated by experience. Just
because the controls have been neutralized in a stable turn doesn't mean
slip and skid are not noticeable. A good pilot will pick up on an out of
doghouse ball with no trouble at all.
Its for this reason that getting students off the ball and outside the
airplane is prime early on in flight training.
Its important to note here as well, considering the totally incorrect input
I've been seeing lately on these forums by a specific poster, that there is
a HUGE....and I'll repeat this for clarity ...HUGE difference between the
way a plane is flown in VERY conditions, and when on the gauges. The very
essence of attitude instrument training is in teaching the pilot to make
this transition from using physical sensing to NOT using physical sensing.
Finally; you teach people to fly airplanes using physical and visual cues.
This doesn't mean that instruments are not useful and shouldn't be used
while flying using these cues.
It does mean however that over concentration on using a ball for
coordination quality at the expense of stressing outside references can
deter from a student's development of the necessary physical cues needed to
become a good pilot.
Pilots need go no further in verifying the validity of what I have said here
than approaching the next airshow demonstration pilot they meet and asking
them,
"Do you check your ball even ONCE while performing?"
I already know the answer to this question :-))
