[NSRCA-discussion] APPARENT GEOMETRY (PARALLAXED VIEW)

[rcmaster199 at aol.com]

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. 
 
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.
 
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.
 
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.
