10.0pt;font-family:Arial;color:navy'>I downloaded a judging training manual for
CL stunt flying and the rulebook descriptions. These guys have an extreme case
of the distortion to the judges’ viewpoint due to the hemispherical
flight envelope. Their geometry is described and flown from the pilot’s
perspective. Loops look like circles to the pilot and ellipses to the judges.
In the training manual I found, each maneuver is drawn with the accurate rulebook
geometry from the pilot’s perspective overlaid with an expected distorted
figure from the judges’ point of view.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>What I did to help train my pilots and
judging eye was to walk to end of flight box, staying on judging side of flight
line at contest, and watched 4 or 5 skilled pilots flying their center
maneuvers. It produced the same visual effect on their center maneuvers
as standing at center of box and looking at end maneuvers. (Realize this
only applies to the center maneuvers for eyeball training) the assumption is
the center maneuvers are flown normally more accurately than end box
maneuvers. The added bonus was I could see if the pilots where doing
correct true verticals and horizontals at my end of the maneuvering box. The
surprising flaw I noticed was some would not fly their bottom horizontals
flat. Some would also not pull a true vertical. Occasionally I would see a
pilot off as much as 20º from true vertical. They would often have a
slight climb in them as they approached the end of the box. I found going
out and experiencing was my best teacher. Class rooms talks are great but they
can't reproduce all of the geometry that an experienced judge gains
from sitting the flight line year after year. When contests had more
man power to run a contest it was discussed about having turnaround judges at
one time.</span></font><font size=2 color=black face=Verdana><span

searched the book and found no wording written that describes what the pilots'
responsibilities and the judges' responsibilities are in the performance of the
skewed apparent geometry. There is a statement in the Judges Training tape in
regard to end maneuvers.... that these will appear different even when
accurately flown. The oness is essentially on the judges to know how the True
Geometry should appear when flown at an angle to the eye, and must not
downgrade for Apparent or Parallaxed appearance difference.<o:p></o:p></span></font></p>
