# Rules

**Basic rules**

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

**CLASSES**

**Paragliders**

** Fun:** All gliders up to and including LTF 1-2, EN B or equivalent.

** Sport**: All gliders (Cerified Gliders only)

**Tandem**: Tandem Gliders

** Ozone : **Any Ozone Glider (Fun and Sport)

**Women** : Any Glider (women pilots only)

**Hang Gliders**

**Class 1** (Flex Wings)

**Class 5** (Rigid Wings)

**CATEGORIES**

There are two different categories.

1. The sum of the best 3 flights (All Classes)

2. The best distance flight in km (with no turnpoints) Fun and Sport

**Tracks value**

- Free flight (Free distance up to three turnpoints.)
**1 km = 1,00 p** - Flat triangle (Triangle which does not conform to FAI triangle specification.
**1 km = 1,30 p** - FAI triangle (Conforming to the FAI definition - the shortest leg of the triangle must be at least 28% of the total triangle).
**1 km = 1,75 p**

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