Safety & Certification

Certification from Day One

We structure work so every test point becomes a traceable safety artifact. Hydrogen operations are engineered with PRD & ventilation, leak detection, and cert-ready processes grounded in ARP4754A/4761 and DO-160/DO-178C.

Program Framework

A disciplined flow: requirements → architecture → analysis → test → evidence. We keep advisory AI outside the safety-critical path while automating data integrity and reports.

Requirements

Safety goals cascade into verifiable, testable requirements.

Analysis

HAZOP/FMEA; FHA/PSSA/SSA aligned with ARP4754A/4761.

Evidence

Automated artifacts tied to datasets, tests, and means-of-compliance.

Certification & Authority Mapping

Artifacts flow cleanly into authority-specific packs.

ARP4754A / 4761

System process with FHA/PSSA/SSA; hazards traced to design mitigations and test evidence.

DO-160 / DO-178C

Environmental qualification + software lifecycle. Advisory AI kept out of critical functions.

Engine / Airport Norms

Means-of-compliance for engines and ground ops—exportable across authorities.

Hazards & Controls

Design mitigations are validated by test and modeled in safety analyses.

Evidence Pipeline

  1. Define: Safety requirements, acceptance criteria, and instrumentation plans.
  2. Test: Pressurized single-sector, stability/NOx, PRD and ventilation trials.
  3. Analyze: Trace results to hazards and mitigations; update HAZOP/FMEA.
  4. Publish: Authority-specific packs with versioned plots, tables, and logs.

All artifacts are versioned and traceable to requirements and test IDs.

Safety FAQs

How do you manage hydrogen leaks?
Leak-before-burst philosophy, ventilation design, and sensor coverage with clear alarm logic and procedures.
What about overpressure events?
Pressure Relief Devices (PRDs), staged regulation, and validated discharge paths to safe locations.
How is software handled?
Safety-critical software follows DO-178C; advisory analytics are separated and never gate safety actions.
Will this scale across airports?
Yes. Playbooks, facility interfaces, and evidence packs are modular and exportable to multiple authorities.
