Purpose and description
Enable an agent to recognise ski jumping activity, assess a jump and its operating conditions, and identify permitted next actions under the applicable practice or competition rules.
Ski jumping is a Nordic skiing discipline in which athletes descend a purpose-built inrun, launch from a take-off table, and land on a sloping landing hill, with competitive results combining distance and judged execution under applicable scoring rules.
It can be Classify an observed attempt as ski jumping and link it to its session, hill and athlete.; Record phase-specific observations to identify where an attempt succeeded or broke down.; Check recorded prerequisites and surface missing evidence before an authorised person makes a start decision.; Calculate or explain a result using recorded measurements and the identified scoring rules.; Compare attempts while exposing differences in hill, gate, wind, surface and evaluation method.; Route holds, disputed measurements and compliance questions to the responsible official or coach..
Distinguishing features
The attempt uses a prepared inrun and takeoff transition into a flight toward a sloped landing area, distinguishing it from incidental airborne movement during downhill skiing.
Flight distance and controlled execution are central performance concerns; a planned repertoire of flips or twists does not define the activity as it does in freestyle aerials.
An attempt has an identifiable takeoff, flight, landing and outrun sequence that can be assessed separately.
A jump performed within Nordic combined remains a ski jumping attempt, while the combined competition also requires a separately modelled cross-country component.
Snow-covered and artificial-surface sessions can instantiate the same activity; surface material alone does not determine whether an attempt is ski jumping.
Scope
+ The sequence and execution of an individual ski jump
+ Training sessions and competitive attempts, including their participation and progression conditions
+ Jump distance, execution assessment and results under an identified rule set
+ Interactions among athlete, equipment, hill configuration and environmental conditions
+ Decisions to prepare, authorise, hold, interrupt or conclude an attempt
- Engineering, construction and maintenance of the ski jumping hill as infrastructure
- Manufacture and general product lifecycle of skis, bindings, boots and suits
- Athlete medical diagnosis, treatment and rehabilitation
- Cross-country skiing and the overall combined result in Nordic combined
- Freestyle aerials, ski cross and terrain-park jumping as separate activities
- Administration of sporting federations and venues beyond their role in a jumping session
Characteristics
- Activity context
- introductory practice | technical training | trial or qualification | scored competition Determines the purpose of the attempt and which assessments and progression rules apply.
- Applicable rules
- identified rule document, edition, event provisions and effective date Prevents eligibility, equipment, scoring and procedural requirements from being treated as universal or timeless.
- Hill and configuration
- linked hill record, declared hill classification, reference dimensions and active configuration Provides the physical context needed to interpret an attempt and compare performance.
- Start gate
- hill-specific gate identifier and record of any change Identifies a controllable condition affecting the approach and potentially the evaluation of a competitive attempt.
- Inrun speed
- km/h or m/s, with measurement location and timestamp Supports interpretation of takeoff conditions without assuming that speed alone explains distance.
- Jump distance
- m, with landing reference, measurement method and verification state Records a central outcome while preserving how the distance was established.
- Wind observation
- m/s and direction, with sensor location and observation interval Supports decisions about attempt conditions and any rule-governed scoring adjustment.
- Execution assessment
- judge marks or deductions under the identified scoring system; qualitative observations for training Distinguishes the quality of flight and landing from distance alone.
- Attempt state
- planned | preparing | awaiting authorisation | authorised | in progress | completed | held | cancelled Makes the next available action explicit and prevents a scheduled attempt from being mistaken for an authorised start.
- Result disposition
- not assessed | provisional | accepted | under review | invalidated, with reason Separates physical completion of a jump from acceptance of its competitive result.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Activity identity and context Establishes what counts as the ski jumping activity and how an attempt belongs to a wider session or event.
The model must distinguish a jump from neighbouring skiing activities and avoid absorbing an entire combined sport.
Activity boundaries
Tests whether the observed activity has the characteristic ski jumping sequence and purpose.
Recognise a ski jumping attempt
Record the prepared inrun, takeoff, flight and intended landing context rather than classifying every airborne skier as a ski jumper.
- What observed features establish that this is a ski jumping attempt rather than a freestyle aerial or incidental jump? boundary
- What marks the beginning and end of the attempt for this session's recording purpose? definition
Session and event membership
Places the attempt within training, a standalone jumping event or the jumping component of a combined event.
Locate the attempt in its format
Keep the individual attempt distinct from the round, session and any wider competition result.
- Is this attempt practice, qualification or competition, and which session and round contain it? definition
- Which outcomes belong to ski jumping here, and which belong to a linked team or combined-event model? boundary
Hill and attempt conditions Records the hill configuration and changing conditions encountered by a specific attempt.
Distance and execution cannot be interpreted adequately without the conditions under which the skier approached and used the hill.
Hill and start configuration
Identifies the hill, its reference dimensions and the selected starting position.
Establish the physical reference
Link the attempt to a documented hill and gate configuration, preserving changes between attempts.
- Which hill record supplies the reference dimensions and classification used for this attempt? provenance
- Which start gate was used, and was it changed relative to the relevant comparison attempts? measurement
Wind and surface context
Captures environmental observations with enough timing and location detail to associate them with the attempt.
Associate conditions with the jump
Distinguish measured conditions from general weather reports and record the active inrun and landing surfaces.
- Which wind measurements cover this attempt, and where and when were they collected? measurement
- What surface condition or weather change prompted inspection, a hold or reassessment of the session? action
Jump execution Represents the connected phases of the skier's movement and the evidence available about each.
A single distance or score cannot identify whether an observed issue arose during approach, takeoff, flight or landing.
Inrun and takeoff
Records the approach and transition from supported motion into flight.
Describe entry into flight
Capture measured speed and observed takeoff timing or posture without turning unverified coaching interpretations into established causes.
- What inrun speed was measured, at which location, and by which instrument? measurement
- Which video or observer evidence supports the assessment of takeoff timing and body position? provenance
Flight, landing and outrun
Tracks airborne control, landing execution and the skier's completion of the outrun.
Separate flight and landing outcomes
Record flight stability, landing form, falls and recovery separately so a long jump does not imply a controlled completion.
- What evidence describes ski and body control during flight and the landing form, including any observed telemark landing? measurement
- Did the skier complete the landing and outrun under control, and how does the applicable assessment define completion? definition
Evaluation and results Connects measurements and assessments to an explainable result under a specified rule set.
Ski jumping evaluation may combine distance, judged execution and conditional adjustments, which must remain traceable.
Distance and execution evidence
Maintains the original observations used to evaluate the jump.
Preserve assessment inputs
Keep measured distance, individual judge assessments and their verification states distinct from the derived total.
- How was the landing reference identified and converted into the recorded jump distance? measurement
- Which judges or assessment process supplied execution marks, and what rule provisions govern their use? provenance
Score and progression
Derives accepted outcomes and their implications for ranking or further participation.
Derive an auditable result
Identify applicable scoring components, any wind or gate adjustments, aggregation rules and unresolved reviews before treating a ranking as final.
- Which rule edition and event format determine the distance conversion, execution contribution and any wind or gate adjustments? provenance
- Given the result's current disposition, what ranking, qualification or next-round action follows? action
Readiness and attempt control Records prerequisites, responsible decision-makers and the attempt's authorisation state.
An agent must distinguish readiness evidence from permission to start and route consequential decisions to the appropriate person.
Athlete and equipment readiness
Links athlete participation conditions and equipment checks to the intended hill and session.
Establish recorded prerequisites
Record required eligibility, supervision and equipment-check outcomes without inferring readiness solely from prior performance.
- What participation or supervision requirements apply to this athlete on this hill, and who confirmed them? provenance
- Which ski, binding, boot or suit checks are required here, and what unresolved outcome prevents clearance? action
Start, hold and interruption
Tracks the controlling signal and decisions before and between attempts.
Control the attempt transition
Associate each authorisation, hold or cancellation with its responsible person or system, time and reason.
- Who may authorise the start, and what signal or instruction establishes that authorisation for this attempt? action
- If the attempt is held or cancelled, what condition must be reassessed and who may permit it to proceed? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
