Basic rules

The Annecy XC challenge will use the same rules as for the XContest with the following differences.


Sport: All gliders

Fun: All gliders up to and including DHV 2 or equivalent.

Tandem: Tandem gliders


There are three different categories.

1. The longest free distance flight in km (with no turnpoints - will be scored later)

2. The best flight (with 3 turnpoints and different values, see below and XContest rules )

3. The total accumulated points during the time for the comp (15/4-15/9)

Tracks value

  • Free flight (Free distance which not conform the triangle track specification. 1 km = 1,00 p
  • Flat triangle (Triangle which not conform FAI triangle specification. 1 km = 1,20 p
  • FAI triangle (Triangle conform to the FAI definition (the shortest leg of the triangle must be at least 28% of the total triangle). 1 km = 1,40 p

A flight may be scored as a triangle, when the distance between start point and finish point is less than 10% o f the entire distance as given by the 3 turn points. The scoring distance will then be given by the turn point distance, minus the gap (finish to start) distance.
