tout est là : General_Rules_17.pdf et comme rien de spécifié dans les règles F5J ce sont donc les règles générales qui s'appliquent =>
a) The contest should be interrupted or the start delayed by the contest director in the following circumstances and in other exceptional circumstances decided by the contest director:
i) Unless specified otherwise in the rules for a category or a particular class, the wind is continuously stronger than 12 m/s measured at two (2) metres above the ground at the starting line (flight line), for at least one minute
ii) The visibility prohibits proper observation of the models (especially in case of F/F or R/C contest) or due to atmospheric conditions it would be dangerous to continue the contest.
iii) It is necessary to reposition the starting line. This may only take place between rounds, or between tasks or groups in F3B and between rounds or groups in F3J.
iv) The prevailing conditions are such that they may lead to unacceptable sporting results.
v) For F3A, F3M, F5A, F3C, F3N, F4C, F4H, F3D and F5D, when the sun is in the manoeuvring area.
vi) Any incident affecting safety or requiring access for emergency services.
b) In the event of an interruption during a round, the contest director must decide the action to be taken to complete, repeat, or cancel the round. The remainder of the round may be completed as soon as conditions allow, with adequate notice given to all competitors and team managers.
In the cases described, the organiser is not obliged to return the entry fee nor repeat the contest. The results will be based on the scores of the finished rounds.
An interrupted contest can be extended if the requirements of C.17.1 are met.
mais 12m/s pendant 1min cela fait souvent des rafales à plus de 60km/h et généralement tu n'auras plus beaucoup de compétiteurs prêts à en découdre sauf en concours international.
