13 = Task cancellation

If the competition director feels there is a possibility of a task being cancelled due to deteriorating weather, he will not use an ordered launch. After take-offs have started the organisers competition director may suspend flying if to continue is dangerous or if he regrets starting the task. If the period of suspension is sufficiently long to give an unfair chance to any competitor, or it is clear that weather conditions are deteriorating, the director shall may cancel the task, regardless of how many competitors have already taken off. In the event of a task cancellation, this shall be communicated to competitors who are in the air by the use of at least a clear and agreed visual signal displayed on the landing deck(s). Once all competitors in a class have taken off, or had the opportunity to take off, the task may not be cancelled other than for reasons of force majeure.
