A good technique is to pick a spot on the ground just above the cowling and
watch how it moves relative to the cowling when you start the turn. For
instance, when rolling left, for a left turn, without any rudder input, the
spot on the ground will initially move the wrong way relative to the cowling
(i.e., to the left, because the nose is yawing to the right). However, with
proper application of left rudder accompanying the left aileron deflection,
the spot will initially remain stationary. In my Cherokee, this effect is
small. I don't know how larger aircraft behave.

Since my simulator is not full-motion, I can't judge the quality of a
turn by feel. However, it stands to reason that I should be able to
detect slipping or skidding visually, by watching how the horizon
moves out the window--after all, any movement of the aircraft will
change the view out the window. Can anyone offer suggestions on how I
can best recognize a coordinated turn by looking outside the aircraft?

My guess is that, if the horizon doesn't move in a direction other
than horizontally (aligned with the horizon) the turn is coordinated,
but I'm not sure about this (I'm still doing experiments).
