In short, the PMA recommends to change the way paragliding tasks
are concluded by changing the End-of-Speed-Section as we know it now (the ESS
cylinder) to an ESS inverted cone, or alternatively to award altitude bonus to
pilots entering the ESS cylinder. By doing this, and tweaking the angle of the
cone or the amount of altitude bonus points awarded, the optimum speed for the
final glide can be adjusted. Any pilot who goes faster will be punished on
points. In all, the race will more or less be concluded in the last thermal BEFORE the
final glide, and there will be absolutely no motivation to race into goal at
high speed. This should lead to competition paragliders being designed with the
emphasis on different properties, namely good handling/climbing characteristics
and good performance in the optimum speed range. At this stage the PMA has come
to the conclusion that the cone should have a slope of 4:1, but this may be
adjusted in the future to match the required optimum speed. Note: The PWC is actually working on conical end of speed section principles and
envisages applying it to a competition soon. The second parameter of the new Competition Class is a flat aspect ratio (A/R)
limitation of 7. 0 or less. Current designs have already shown that it is
possible to build very nice wings for competition within this A/R limit and it
is our belief that there is currently no need for more A/R to fly rewarding
tasks. The A/R of a wing is determined according to the following formula: 4C
A+2½B.
