4.3 Contest Numbers


4.3.1 The contest numbers, as validated by the Organisers, shall be displayed:

a. On the underside of the right wing, approximately 2.5 m from the centreline of the sailplane with the top of the figures or letters towards the wing leading edge. The height of the letters or figures should be not less than 80% of the wing chord.

b. On both sides of the tail fin and/or rudder. These must be at least 30 cm high.

c. On the glider trailer and crew car.


4.3.2 Contest numbers shall consist of not more than three letters or figures or a combination of letters and figures in a plain block style with a single colour that contrasts strongly with the sailplane's background colour.


4.3.3 The Organisers may require competitors to modify contest numbers that they deem to be similar, confusing or not complying with this paragraph 4.3. Competitors not complying with the Organiser's requirements may be denied competition launches.


Contest numbers on the sailplane and vehicles not only assist the Organiser’s and other competitors to identify the sailplane, but also enable the public and the media to identify the sailplane, the pilot, the crew and the country.
