International Sport Kite Compulsories Book (ISKCB)


The IRBC (a coming together of the AKA, JSKA and STACK) competition figures have now taken over from the old STACK figures as being what we should all be flying from now on. These are the animated versions of the static diagrams taken from the ISK Compulsory Book. The animations allow you turn both the grid and figure lines on and off. This can give flyers an idea of how the figures look when seen against a clear sky (how the judges will view them).

The animations are produced in Flash. In order to view them you will need the Flash plug-in (version 4 or better). As of 9 April 2013 if your browser isn’t capable of viewing Flash animations you should see an HTML5 animation instead. These don't have the ability to turn off the grid or figure lines. If you’re viewing on a phone the animations will only look good if you turn your phone horizontally.

The figures have been updated to meet ISKCB v2.2.1 (5 December 2011). Because I was asked to keep the obsolete figures online I haven’t updated my numbering of the figures, so go by the name not the number. The dual-line team figures now include animations for 3, 4 and 5 person teams.

Rule Changes

Version 2.2 – 6 August 2009

  1. Eliminated description of key components and added broad description of scoring III.A.
  2. Combined prior “Critical Components” and “Other Components” into an aggregate heading, “Judges will Particularly Consider,” for all figures. No changes to these components were made other than re-labeling.

Version 2.2.1 – 5 December 2011

  1. Amendments to figure diagrams DT04 and DT16 (removal of speed control elements previously integral to lines of entry and exit).
  2. Amendment of “Judges Will Particularly Consider” notations to coincide with the above.

Version 3.0 – 1 April 2017

  1. Minor amendments to text for clarification
  2. Additional Definition: Synchronicity
  3. Figures removed to Obsolete List (DT14, DT15, MP05, MI18)
  4. Additional figures (DI20, DP19, DT17, MI23, MI24, MI25, MI27, MI28, MI29, MI30, MI31, MI32, MI33, MI34, MI35, MI36, MI37, MP14, MT12)
  5. Change of entry and exit points in figure MI03 and MI13

Unfortunately it’s unlikely that I’ll be able to add any new animations in order to meet the v3.0 update to the figures that was published in April 2017. You should make sure that you have the latest ISK Rulebook and Compulsories list which you can dowload in PDF format here.
