Bindings: Special mechanical devices which attach the boots to the skis. The bindings, which are meant to unfasten from the boots in case of a fall, must be mounted parallel to the run-direction and must be placed so that a maximum of 57% of the entire ski length is in front of the bindings.

Fall line: A designated line on the out-run of a ski jumping hill. If a ski jumper loses his balance and falls after the fall line, style points will not be deducted from his jump.

Flight phase: The period of the jump between takeoff and landing in which the athlete is airborne

Gate change: An adjustment made to the starting gate’s elevation by the technical jury or a coach which accounts for wind changes, athlete skill or other factors which may impact overall safety. Decisions to change the gate must be announced at least 25 seconds before an athlete’s turn, and coaches are allowed to change the starting gate a maximum of three positions.

Gate compensation: Points that are added to or subtracted from a jumper’s final score to account for changes in the gate’s elevation. Points are deducted for a higher starting gate, while points are added for a lower start gate.

Hill profile: Refers to the characteristics of a jumping hill which determine the difficulty of a jump such as elevation, geometric shape and length 

Hill Size (HS): The distance between the takeoff table and the end of the landing area, which is beyond the K-point

In-run: The portion of the jump during which the athlete travels down the ramp

Judges: Five individuals who evaluate each jumper’s style, flight and landing. The highest and lowest scores awarded to a jumper by the judges are eliminated.

K-point: The point of the hill where it begins to flatten out, which is equivalent to the height of the hill. The K-point typically is designated by two red lines which run down both sides of the landing hill and determines the number of distance points awarded to a jump, meaning jumpers can earn more points for landing beyond the K-point.

Large Hill (LH): The larger of the two Olympic ski jump hills

Landing zone (L-point): The bottom part of the hill on which athletes aim to touch down after the jump. The landing zone is constructed to mimic the jumper’s trajectory, minimizing their impact upon landing. A jumper earns distance points based on where in the landing zone they set down.

Norm point (P-point): The distance between the takeoff table and the beginning of the landing area, which is just above the K-point. It usually is approximately 80% of the distance to the K-point.

Normal Hill (NH): The smaller of the two Olympic ski jump hills

Out-run: The flat area at the bottom of the hill where skiers decelerate and stop

Speed check: A controlled maneuver performed by the jumper in order to reduce their speed going into the jump. The movement allows skiers to adjust their speed according to the jump size, as well as the environment’s conditions, to prevent overshooting a jump and ensure safety.

Starting gate: The specific point on the in-run from which an athlete begins their descent down the hill

Style points: Points awarded based on flight, landing and out-run. Several factors impact style points, such as balance, body position, movement during flight, elegance and form.

Takeoff: At the end of the inrun, the moment where the jumper takes flight

Technical Jury: A group of individuals who ensure the entire competition is carried out in a fair and safe manner. The jury makes decisions regarding in-run length, gate changes, restarts, postponements, disqualifications, sanctions, protests and more.

Telemark position: Landing with one ski in front of the other, lunging forward. The maneuver is named after a region in Norway.

Trial round: A period before the qualification and final rounds in which athletes are allowed one practice jump

V-position: The position of the skis most jumpers use while in the air. The skis are touching or nearly touching at the tail, and spread apart at the tips to form a "V." This position improves the aerodynamics of the ski jumper.

Wind compensation: Points which are added to or subtracted from a jumper’s final score to account for wind conditions. Points are deducted for more favorable conditions, such as a headwind pushing the jumper forward, while points are added for unfavorable conditions, such as a tailwind pushing against the jumper.
