That is correct. It is even more important with the TSIO550 due to
turbos and intercoolers. If I am alone in the airplane I have landed
many times with the elevator hitting the stop. The landings have
resulted in perfect touchdown but I don't think they would be very
successful if I hadn't changed the position of the HS to -.06 degrees.

Rick -
I understand that the reason for going to a -0.6 degree position on the
HS on our ES's was to provide more control in the landing phase. This
was done because of the heavier nose wi/ the IO-55x engine and a three
blade metal prop.
Anyone else hear that?
John
A bad scenario is that you have the horizontal so far "off" (leading
edge
up) that you run out of up elevator movement in the flare. The other
bad
scenario is that the horizontal is so far "off" (leading edge down)
that you
need "lots" of down elevator at high speeds (added drag).
