<DIV><FONT size=2>About the only way I can think of to show the effects of
parallax on a correctly flown turnaround maneuver would be to film it from as
close to perpendicular to the flight path as possible, and at the judges'

seminar.</FONT></DIV>

<DIV><FONT size=2>At the appx 45 to 55 deg observation angle of the judges
station, a 45 deg up/down line (half cuban) would appear steeper than what is
actually being performed. If it looks like a 45 from the judge's station
(holding up a 9th gradeer's geometry class triangle), its too shallow.
The appearance of 60 deg (same method) would be closer to actually being the
45 deg line.</FONT></DIV>

<DIV><FONT size=2>Note that if the pilot doesn't make use of the full box, the

GEOMETRY (PARALLAXED VIEW)</DIV>
<DIV><BR></DIV>
<DIV>A question has been posted from an IMAC gentleman (who is trying
to write better IMAC rules) as to how Pattern people fly and judge
skewed appearance of maneuvers at box ends or in center when tall maneuvers
(Hourglass, Vert Sq 8, Rolling Ess, etc) are involved. </DIV>
<DIV> </DIV>
<DIV>Some of us have 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.</DIV>
<DIV> </DIV>
<DIV>Spoke with Don about this earlier today and we decided to present the
question to the group and get some conversation going. We should be explicit
in the book regarding how such Apparent Geometry should be treated....ie-
what is the pilot's responsibility and what is the judge's. Description
improvements could be written over the next couple rule cycles.</DIV>
<DIV> </DIV>
<DIV>The pilot's responsibility may appear easy.... they simply need to fly
precise geometry per the book. True enough, BUT.....consider what is
actually flown, especially by the top guys, and what scores well. These are
not necessarily as precise as one might think. The better pilots tend to fly
purposely flawed maneuvers that give the impression of precision.
