In aerials, competitors hit the jumps or ‘kickers’ at speeds of 60+ km/h, launch themselves some 15 metres in the air. Competitors must perform two different jumps consisting of single or multiple somersaults with or without twists. Each jump must vary by one somersault or one twist. Points are awarded for take-off (20% of score), form in the air (50% of score) and landing (30% of score). Scores of both jumps are added together for a final mark.
