Aerials competition consists of a two-jump elimination round and a two-jump final. The 12 individuals with the highest score in the elimination round move on to the finals, where they start in reverse order of their initial placement. Results from the qualifier do not carry over to the finals. The competitor with the highest total score in the finals wins.
The athlete's jumping performance is judged based on three components: air, which counts for 20 percent of the score; form, which counts for 50 percent; and landing, which counts for 30 percent. Competitors can receive up to 30 points.
Seven judges evaluate the competitor's performance using a split-scoring system. Five judges independently determine the air and form score, which combined makes up 70 percent of the total. The judges use a 7-point scale, and the high and low marks are thrown out, making the highest possible score 21.
Judges determine the air score based on the take-off, height and distance of the jump. They evaluate the form score based on the position of the body, skis, arms, hands and poles while in the air.
Two judges independently evaluate the landing on a three-point scale. The average of the two scores is multiplied by three to obtain the total, making the highest possible score nine. Judges look for a balanced, stable and controlled body position throughout the landing
The combined air, form and landing score is multiplied by the jump's degree of difficulty (DD) value to obtain the total. To determine the total DD, judges add the base score of 1.5 to the jump's value. For example, the total DD for the daffy, worth .2, would be 1.7 (1.5 + .2).
Athletes take one run down a course. The Olympic competition consists of a one-run elimination round and a one-run final. The top 16 competitors from the elimination round advance to the finals, where they start in reverse order of their placement. Results from the qualifier do not carry over to the finals. The skier with the highest score in the final round wins.
The athlete's performance is based on three components: turns, which count for 50 percent of the score; air, which counts for 25 percent; and speed, which counts for 25 percent. An athlete can receive a maximum of 30 points.
Seven judges use a split-scoring system to evaluate a competitor's performance. Five judges independently evaluate the turns. The high and low scores are thrown out, and competitors can receive up to 15 points. Judges evaluate how well skiers use an aggressive, controlled technique and whether they stay in the fall line – the shortest way from the starting point to the finish line.
Two judges independently evaluate the aerial maneuvers on a 7.5-point scale. The scores are averaged, meaning competitors can receive a maximum of 7.5 points. Judges evaluate the athlete's form, the height of the jump and the degree of difficulty.
The speed score is based on the amount of time a competitor takes to complete a run. The competitor's time is compared to the pacesetters' times. Four pacesetters ski the course on the day of competition and receive scores from the judges. The pacesetters should be competing in the event and are selected by the competition officials.
The time of the pacesetter who receives the highest score is the pace time. The pace time is equal to 5.625 points. For each 2.5-percent increment of time difference above or below the pace set, .2 points are subtracted or added to the athlete's score.
