OLC-ParaHangGliding Competition

Issue: 4.3.2008


The goal of the On-Line Contest (OLC) is a timely scoring of cross-country flights, free from the burden of flight declarations, to allow an easy and up-to-date comparison of decentralised cross country flights. The increase of the number of cross-country flights is another goal of the OLC.

1. Documentation

Documentation of the flights is achieved with GPS based flight recordings, validated files in IGC format. There are two levels of flight validation:

IGC-valid (green V-point in the info window)

These IGC files have to be generated exclusively by IGC approved flight recorders. A current list of IGC approved flight recorders is available at the IGC-website (http://www.fai.org/gliding/gnss/).

OLC-valid (blue V-point in the info window)

All other recorders which generate IGC files with a software which is approved by the OLC. A current list of the OLC approved software for these recorders can be found at: http://www2.onlinecontest.org/validate.php. Official observers are not required.

2. Country of scoring

The flight will be scored for the OLC in the country where the glider took off.


2.1 Orographically defined competitions:

The flight is scored for the orographically defined competition area, if at least 50% of the recorded tracking points with constant recording intervals are positioned in that area.

2.2 Orographically defined areas:

Alps (definition will be added soon).

3. Scoring distance

The flight has to be undertaken in free flight without any means of propulsion, from scoring start point to scoring finish point. The flight will be scored from scoring start to scoring end. Scoring start is the beginning of propulsion less flight, scoring end is the end of propulsion less flight. Start point, waypoints and finish point must each be actual GPS fixes of the flight track. The scoring distance is calculated by the OLC system.

3.1 OLC (also described as OLC-PHG in the scoring boards for paragliding/hanggliding)

After the flight the start point, up to three turnpoints and the finish point are determined on the flight trace, so that the scored points for the flights are maximized. A flight can be scored as a triangular flight, if the distance between start and end point remains less than 20% of the triangular distance defined by the three waypoints. The scoring distance is then defined as the triangular distance around the three waypoints minus the distance between start and finish point.

3.2 OLC-Classic

After the flight the start point, up to five turnpoints and the finish point are determined on the flight track, so that the scored points for the flights are maximized.

3.3 OLC-FAI (in the style of the FAI rules)

The maximum distance FAI triangle will be placed in the recorded, closed circuit flight track. The shortest leg has to be at least 28% of the total distance, or if the total distance is more than 500 km then the shortest leg has to be at least 25% and the longest leg can be a maximum of 45% of the total distance. The flight track counts as a closed circuit if there is at least one valid GPS fix within one km of the starting point.

4. Takeoff procedures

Foot-launch, winch-launch and for hanggliders (FAI 1, FAI 2, FAI 5) ultralight-towing. When using ultralight-towing, the maximum release altitude may be at 1000m (AGL) above the airport.

5. Scoring, points

5.1 OLC (also described as OLC-PHG in the scoring boards for paragliding/hanggliding)

The distance from start point around the three waypoints to the finish point will be calculated with 1,5 points per kilometre in any case. Triangular flights, meeting definition requirements of a FAI-triangle with the shortest leg adding up to at least 28% of the total distance, will be calculated with 2 points per kilometre. All other triangular flights will be calculated with 1,75 points per kilometre. At all times, the calculation rule resulting in the highest point sum will be employed. The result will be approximated to a hundtreth of a point and represents the scoring distance for the flight.

5.2 OLC-Classic

1 point per kilometer is granted for the distance from start point around three turnpoints to the fourth turnpoint. For the distance between the fourth turnpoint to the fifth turnpoint 0.8 points per kilometer are granted. For the distance between fifth turnpoint and the finish point 0.6 points per kilometer are granted. Turnpoint four and five, as well as the finish point can be the same.


The distance around three waypoints are scored with 2 raw points per kilometer.

6. Flight claims

Flight claims will be accepted only at www.onlinecontest.org. Claims have to be submitted within 14 days after the flight day (00:00 o'clock local time). The IGC-file has to be submitted as part of the flight claim. By submitting the flight the participant certifies that the flight took place as claimed.

7. Scoring period

The scoring period ends on the second Monday of oktober. The competition for the following 12 month period begins on the following day, and so on.

8. Winners and prize-distribution

Winner and Online Contest Champion 2008 of each valuation (OLC, OLC-Classic and FAI-OLC) is the participant who scores the highest number of points with six flights.

9. Publishing of data/Right of use

The participant agrees that his flight data and flight-routes will be published on the Internet at www.onlinecontest.org The right of use for the flight track files is non-exclusive but is granted non-revocable and indefinite to the organizers of the OLC.

10. Validation

Flights and scores will be made permanent if no objections have been filed against them within 4 weeks after the corresponding weekly deadline. Deadline for objections against flights made after the 15th September will be the Wednesday after the second Monday in October. Flight data in the form of IGC data files must be kept by the participant until one month after the end of the current competition.

11. Participation and Registration

Participation is free of charge (OLC is financed by sponsors, donations and contributions by the OLC supporting club "Segelflugszene e.V."). Registration can only be made online via the forms provided at www.onlinecontest.org and has to be made once a year. By their registration the participants agree to the competition rules.

12. Scoring classes

Annotation: Scoring classes have to be chosen manually bei the pilot. Explanations concerning class criteria can be found on the website of the Deutschen Hängegleiterverbandes (DHV).





Detailled explanations on glider types can be found in the database of the DHV technical department:


12. Airspace Violations

The OLC organizers have to assume that the participants in the contest will not violate restricted airspace during their flights. ATC clearances are necessary to enter certain airspace. The OLC team will not check if a pilot has obtained the necessary clearance to enter airspace which needs ATC clearance. This is not within our competences and responsibilities. However, if we learn that there has been an obvious violation of airspace then we reserve the right to carry out special actions against that pilot and his participation in the OLC. Of course every pilot is allowed to contact other pilots in case of a potential airspace violation. Violations of air laws or air spaces will be declared by local authorities or agents of each national aeroclub.
