Can aerialists repeat a jump?
A · Advanced · Moguls and aerials · 2 of 2A competitor may not repeat the same aerials jump within a phase. Jumps differ by direction, the number of somersaults or twists, or the twists within a somersault. Inverted jumps are limited to three somersaults, and the jury may cap difficulty at 3.55 or 4.175 for men and 3.55 for women. A three-phase light controls the start.
How it works
- No repeats: each jump in a phase must differ.
- Different inverted jumps: a change of direction or of the number of somersaults or twists; or twists placed differently.
- Somersaults: at most three.
- Upright jumps: at most five positions.
- Jury cap on DD: 3.55 or 4.175 for men; 3.55 for women.
- Skills: the national association vouches the athlete can do each jump.
- Start light: red, then a 10-second yellow, then green.
- Training: at least two hours on competition day.
The glossary has the different jumps, the aerials, the flip, the twisting double, the official training (freestyle) and the degree of difficulty.
Tricky cases
Are a back layout and a back tuck different jumps?
Yes. The rules list them as different.
Can a jumper try a quadruple somersault?
No. Inverted jumps are limited to three somersaults.
A jumper cannot perform the jump they entered. What can the jury do?
Act against them, up to excluding them from the event.
Who decides when the start sequence begins?
The official controlling it, taking wind into account.
Why the rule exists
Banning repeats rewards a wider set of jumps. Caps on somersaults and difficulty protect athletes when conditions or skill levels make big jumps unsafe.
