4. 10km5kmStart Points90° Sector(Infinite Size)Start Line
5. 90°Sector(Infinite Size)0.5kmBarrel90°Sector of 20km size0.5kmRadiusThistle1km taken off task distance for any barrel or thistle turnpoint Turnpoints
6. (Turnpoints) Area Assigned Task or Variable SectorAAT’s will be scored as undeclared tasks and the sum of the radii used will be deducted from the task distance. VS’s will only apply at comps or club task weeks but are scored as declared; otherwise the same.Usually a Competitionselected radii
7. The Finish5km10kmCan be of infinite size90°(Normally 3km)Straight LineSectorFinish Circle(Can be any size)
8. 1000m Height RuleStart/FinishFor 10m of height loss over 1000m, 1km will be deducted from the task distance100km FAI ClubTriangle (103.4km)PCS-STI-MVN-PCS
9. Scoring: ShapeThe soaring weather & airspace takes priorityMax Shape Factor =1.08 (for the 28% FAI Triangle)Can have a dog leg up to 5% greater total distance without a shape penaltyCan have up to 4 waypoints and a start plus a finish( a total of 6)Start/ Finish
10. Shape – Normal(shape factor 1.0)Out and returnNote: A 25% - 45% triangle has a shape factor of 1.050Worst shape is the double O & R & the Goal flight. SF: 0.82. Goal flights are not necessarily straight line, they can be dog legs for example.
