  1. Basic Principles of the Stunt Hemisphereby Keith Renecle 7th July 2006 Belgrade, Serbia

  2. C/L Stunt is Precision Aerobatics!

  3. Basic principlePilots who perform closest to the rules should score the highest points

  4. What does this mean?

  5. What does this mean? • Pilots and judges and judges must have a good understanding of the rules

  6. What does this mean? • Pilots and judges and judges must have a good understanding of the rules

  7. What does this mean? • Pilots and judges and judges must have a good understanding of the rules • Pilots and judges must have the same understanding of the rules

  8. What does this mean? • Pilots and judges and judges must have a good understanding of the rules • Pilots and judges must have the same understanding of the rules

  9. This is a SUBJECTIVE sport!

  10. This is a SUBJECTIVE sport! We must ensure that we do not use SUBJECTIVITY as an excuse for a lack of understanding!

  11. What can we do to help?

  12. Benefits of using 3-D graphicsin C/L Stunt

  13. Benefits of using 3-D graphicsin C/L Stunt Competitors: • A greater correlation between words and illustration

  14. Benefits of using 3-D graphicsin C/L Stunt Competitors: • A greater correlation between words and illustration • WORDS create mental expectation

  15. Benefits of using 3-D graphicsin C/L Stunt Competitors: • A greater correlation between words and illustration • WORDS create mental expectation • ILLUSTRATIONS create visual expectation

  16. Benefits of using 3-D graphicsin C/L Stunt Competitors: • A greater correlation between words and illustration • WORDS create mental expectation • ILLUSTRATIONS create visual expectation • Conflict in expectations creates confusion

  17. Benefits of using 3-D graphicsin C/L Stunt Judges: • Understanding of shape of manoeuvre on sphere as viewed from outside

  18. Benefits of using 3-D graphicsin C/L Stunt Judges: • Understanding of shape of manoeuvre on sphere as viewed from outside Manoeuvres need to be flown accurately from pilot’s view. Judge must therefore correlate what is seen with what the pilot sees.

  19. TECHNOLOGY The present: (Basically no technology!)

  20. TECHNOLOGY The present: (Basically no technology!) • Competitor expectation conflicts with judging result:- has always existed.

  21. TECHNOLOGY The FUTURE!

  22. TECHNOLOGY The FUTURE! Although possible now….. Costs will be prohibitive.

  23. TECHNOLOGY The present: • Conflict between mental expectation created by words, and visual expectation created by drawing:- has always existed

  24. TECHNOLOGY The present: • Conflict between mental expectation created by words, and visual expectation created by drawing:- has always existed • Technology to address this conflict:- Affordable and available today

  25. Use this technology effectively to minimise conflict • Create consistent mental & visual expectation for judge & competitor

  26. Use this technology effectively to minimise conflict • Create consistent mental & visual expectation for judge & competitor • Provide consistent training tool to judge & competitor

  27. Use this technology effectively to minimise conflict • Create consistent mental & visual expectation for judge & competitor • Provide consistent training tool to judge & competitor • Create consistent understanding of manoeuvre appearance on sphere

  28. This presentation shows what is possible now!

  29. With 3-D graphics we can: • See how the manoeuvres fit the sphere • View the manoeuvres from any angle or position in the virtual world • Watch them being performed in real time

  30. Here are a few screenshotsfrom the CL Sim-1

  31. Basic Principles of our Stunt Hemisphere

  32. Why do we have misconceptions about the stunt manoeuvres?

  33. Pitch

  34. Roll & Yaw

  35. It should be dead easy…………. just like golf! All you basically have to do is hit a small white ball into 18 different holes……… How difficult can that be??

  36. How do we go about judging the pattern?

  37. It is obviously important to know exactly how the manoeuvre shapes look, and how they will appear from the various angles. How do we achieve this??

  38. Judges need a good understanding of the principles that govern our stunt hemisphere

  39. Judges Guide • 4B.4 Judging focus • Shape • Size • Intersections • Bottoms

  40. Judges Guide • 4B.4 Judging focus • Shape • Size • Intersections • Bottoms

  41. The flight path of a tethered object like a C/L model
