AMPEL360 Q100 is a model case delivering a Full Digital Information Twin Architecture (FIDITA) for certification-grade hydrogen-electric aviation. It governs knowledge and information as distinct domains with explicit transformation contracts, forming a digital intelligence layer built on a Digital Twin (DT)-native documentation management paradigm:
| DT Domain | Scope |
|---|---|
| Product DT | Continuous synchronization between physical aircraft systems and their authoritative digital representations |
| Documentation DT | Living technical publications that evolve bidirectionally with the product lifecycle |
| Knowledge DT | Uncertainty-aware engineering artifacts with full traceability from discovery to certification evidence |
This repository provides synthetic but structurally realistic program data demonstrating the Knowledge and Information Data Model (KI-DM) applied to a next-generation ~100-passenger regional aircraft concept. It supports EU Clean Aviation and Net-Zero objectives through:
- End-to-end lifecycle management (LC01–LC14)
- Governed GENESIS transitions from exploration to execution
- Incentive-aligned contribution via Teknia Tokens (TT)
- Certification-grade auditability and traceability
| Technology | Description |
|---|---|
| Blended Wing Body (BWB) | High aerodynamic efficiency and integrated volume |
| H₂ PEM Fuel Cells | Primary electrical power generation from hydrogen |
| Distributed / Open-Fan Propulsors | Distributed propulsion architecture for efficiency and noise reduction |
| Peak-Power Buffering | Buffer strategy for transients (energy management and load leveling) |
| Circularity + DPP | Digital Product Passport foundations for lifecycle traceability |
| Principle | Implementation |
|---|---|
| Knowledge ≠ Information | Engineering truth (KDB) is separated from consumable publications (IDB) |
| Uncertainty is First-Class | Every unknown is tracked, planned, and closed with full traceability |
| Automation Without Delegation | ASIT agents execute contracts; humans retain technical authority |
| Incentive Alignment | Teknia Tokens reward uncertainty reduction, not just output volume |
| Certification-Grade Governance | Explicit contracts, auditable transformations, traceable evidence |
| Metric | Value |
|---|---|
| ATA Chapters | 79 |
| Lifecycle Phases | 14 (LC01–LC14) |
| Framework Axes | 5 (O-P-T-I-N) |
| Publication Standard | S1000D |
| Token System | TT v3.14 |
| Knowledge Domains | PLM (Product) + SLM (Service) |
Technical authority remains human and explicit; automation remains bounded, deterministic, and auditable. “This repository demonstrates governance and transformation mechanics, not aircraft certification data.”
- This repository does not replace engineering authority
- It does not assert airworthiness or certification compliance
- It does not automate decision-making
This repository addresses a recurring industry challenge:
Engineering knowledge, documentation, and certification evidence tend to diverge as programs scale and become geographically distributed.
The KI-DM (Knowledge and Information Data Model) solves this by treating knowledge and information as fundamentally distinct domains:
| Domain | Purpose | Authority |
|---|---|---|
| Knowledge (KDB) | What we know, what we don't know yet, and under whose authority | Engineering teams, domain experts |
| Information (IDB) | What is needed, by whom, to execute a specific process | Publication authors, operators, MROs |
| Transformation (ASIT) | How validated knowledge becomes usable information | Automated but governed by explicit contracts |
Key insight: Information is always derived from knowledge—it never creates new knowledge. This separation ensures that:
- Engineering truth remains authoritative and traceable
- Publications can be regenerated from source knowledge
- Changes propagate through governed channels
- Auditors can inspect the complete chain from uncertainty to evidence
The complete information pipeline flows through three major layers:

ASIT (Aircraft Standard Information Transponder) agents execute formal transformation contracts between KDB and IDB. Critical constraints:
| ASIT Does | ASIT Does Not |
|---|---|
| Execute deterministic transformations | Create knowledge |
| Apply validation rules (BREX, schemas) | Make engineering decisions |
| Generate trace matrices | Assume technical authority |
| Log all operations with full provenance | Modify source knowledge |
| Report validation failures | Interpret ambiguous inputs |
Every ASIT transformation is:
- Deterministic — Same input always produces same output
- Reproducible — Can be re-executed at any time
- Traceable — Full audit trail from source to output
- Governed — Controlled by explicit contract definition
The 14 lifecycle phases are split across two management domains:
┌─────────────────────────────────────────────────────────────────────────────┐
│ PLM — Product Lifecycle Management │
│ (KDB / SSOT Authority) │
├─────────────────────────────────────────────────────────────────────────────┤
│ LC01 │ Problem Statement │ Uncertainty orchestration, KNOT/KNU │
│ LC02 │ System Requirements │ Requirements, traceability │
│ LC03 │ Safety & Reliability │ Hazard analysis, FMEA, safety cases │
│ LC04 │ Design Definition │ DMU, ICDs, architecture │
│ LC05 │ Analysis Models │ FEA, CFD, thermal, performance │
│ LC06 │ Integration & Test │ PMU, test procedures, evidence │
│ LC07 │ Quality │ Quality plans, inspection records │
│ LC08 │ Flight Test & Cert │ Certification basis, compliance matrix │
│ LC09 │ Green Aircraft │ Delivery baselines, effectivity │
│ LC10 │ Industrialization │ Manufacturing specs, tooling, CAM │
├─────────────────────────────────────────────────────────────────────────────┤
│ SLM — Service Lifecycle Management │
│ (IDB / SSOT Authority) │
├─────────────────────────────────────────────────────────────────────────────┤
│ LC11 │ Operations │ Ops configurations, customer deltas │
│ LC12 │ Support Services │ In-service support, technical bulletins │
│ LC13 │ MRO & Sustainment │ Maintenance programs, repair authority │
│ LC14 │ Retirement │ End-of-life, circularity, DPP closure │
└─────────────────────────────────────────────────────────────────────────────┘
Why this separation matters:
- PLM = Product knowledge owned by design/engineering authority
- SLM = Service knowledge owned by operations/MRO authority
- Clear handoff = LC09 (Green Aircraft) marks the transition point
- Both are SSOT = Different authorities, same governance rigor

| 900–999 | External surfaces, anti-ice, lightning, general zonal items |
Left/Right convention:
- 3xx = Left, 4xx = Right
- Vertical split (BWB-specific): subzones use
-01upper,-02mid,-03lower where relevant.
The authoritative zone register for AMPEL360 Q100 is maintained in
.../ZONES_REGISTER.csv.
That CSV is the single source of truth for:
- Zone identifiers and names
- Plain-language boundary descriptions
- Primary access points
- Dominant ATA linkages
- Notes and key hazards
To avoid divergence between documentation and configuration data, do not manually duplicate the zone list here. Instead:
- Consume
ZONES_REGISTER.csvdirectly in engineering and publications tooling, or - Generate any human-readable tables (for reports, HTML, PDFs, etc.) from that CSV.
When geometry or zoning changes, update ZONES_REGISTER.csv; derived artifacts,
including tables in downstream docs, should be regenerated from it.

The OPT-IN Framework organizes all 79 ATA chapters across five axes:
| Axis | Name | ATA Chapters | Scope |
|---|---|---|---|
| O | Organizations | 00–05 | General, maintenance policy, operations org, airworthiness |
| P | Programs | 06–12 | Dimensions, lifting, leveling, towing, parking, servicing |
| T | Technologies | 20–80 | All on-board systems (airframe, avionics, propulsion, etc.) |
| I | Infrastructures | 03*, 08*, 10*, 12*, 85, IN-XX | Ground support, H₂ logistics, facilities |
| N | Neural Networks | 95, 96, 97, 98 | AI/ML, traceability, DPP, governance |
Note: Some chapters appear in multiple axes with different sub-scopes (e.g., ATA 08 PROGRAMS vs ATA 08 INFRA)

T_i = P_k · w_i
Where:
| Symbol | Definition |
|---|---|
P_k |
Pool amount (TT) for the KNOT |
α |
Effort weight (default: 0.30) |
Ê_i |
Normalized effort: E_i / Σ E_i |
Î_i |
Normalized impact: I_i / Σ I_i |
I_i |
Effective impact: ΔR_k,i + λ · S_i |
S_i |
Spillover: Σ(a_k→j · ΔR_j,i) for adjacent KNOTs |
λ |
Spillover multiplier (default: 0.50) |
This ensures:
- Contributors who do necessary work are rewarded (effort)
- Contributors who reduce uncertainty most are rewarded more (impact)
- Cross-KNOT contributions are recognized (spillover)
