AMPEL360 Q100 delivers a certification-grade digital information architecture for hydrogen-electric aviation, where knowledge and information are governed as distinct domains with explicit transformation contracts.
This repository contains 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.
| Technology | Description |
|---|---|
| Blended Wing Body (BWB) | High aerodynamic efficiency and integrated volume |
| Hβ 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 β 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 (LC01βLC14) |
| 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. βThis repository demonstrates governance and transformation mechanics, not aircraft certification data.β
- 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 knowledgeβit 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 β Same input always produces same output
- Reproducible β Can be re-executed at any time
- Traceable β Full audit trail from source to output
- Governed β Controlled by explicit contract definition
The 14 lifecycle phases are split across two management domains:

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

| Axis | Name | ATA Chapters | Scope |
|---|---|---|---|
| O | Organizations | 00β05 | General, maintenance policy, operations org, airworthiness |
| P | Programs | 06β12 | Dimensions, lifting, leveling, towing, parking, servicing |

T_i = P_k Β· w_i
Where:
| Symbol | Definition |
|---|---|
P_k |
Pool amount (TT) for the KNOT |
Ξ± |
Effort weight (default: 0.30) |
Γ_i |
Normalized effort: E_i / Ξ£ E_i |
Γ_i |
Normalized impact: I_i / Ξ£ I_i |
I_i |
Effective impact: ΞR_k,i + Ξ» Β· S_i |
S_i |
Spillover: Ξ£(a_kβj Β· ΞR_j,i) for adjacent KNOTs |
Ξ» |
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)
