Aerialists ski off 2-4 meter jumps, that propel them up to 6 meters in the air (which can be up to 20 meters above the landing height, given the landing slope). Once in the air, aerialists perform multiple flips and twists before landing on a 34 to 39-degree inclined landing hill about 30 meters in length. The top male aerialists can currently perform triple back flips with up to four or five twists.
Aerial skiing is a judged sport, and competitors receive a score based on jump takeoff (20%), jump form (50%) and landing (30%). A degree of difficulty (DOD) is then factored in for a total score.
