Glider aerobatics

Aerobatic flying is controlled by FAI (Fédération Aéronautique Internationale,
The World Air Sports Federation) and its sub-commitee CIVA (Commission Internationale de Voltige Aerienne). CIVA is responsible for the administration of aerobatic competition worldwide under the auspices of the FAI. CIVA was formed in 1960 when the first World Aerobatic Championships was held in Bratislava, Czechoslovakia.

Contest flying is performed with a power aircraft or glider in a designed performance zone, a "box", which horizontal dimensions are 1000m andthe upper limit of about 1000 meters and the lower limit of the competition is 200 meters. The sequence is judged by 3-10 jugdes. Rating is based to geometrical standards, and the points will be reduced from certain angle errors, irregular arches, missing lines or so on.

There are four different classes in competition aerobatics. Sportsman, intermediate, advanced and unlimited. The beginners start with sportsman, mainly competing in national contests and the most skilled pilots flying unlimited-class where the sequence is most challenging.

All permitted figures are in the Aresti catalogue. There are thousands of different figures and combinations. Each figure has its well-defined criteria and coefficient of difficulty. By calculating the judges scores with these coefficients you'll get the scoring for the contest.In aerobatic flying the objective is to perform a sequence of aerobatic figures. In contests there is normally 6 sequences flown.
a) Known Programme (Programme 1)
b) Unknown Compulsory 1 (Programme 2)
c) Free Programme (Programme 3)
d) Unknown Compulsory 2 (Programme 4)
e) Unknown Compulsory 3 (Programme 5)
f) Free Unknown Programme (Programme 6)

At least programmes 1, 2 and 3 must be flown to achieve a championship status.
