CompliAir — DO-326A Automation

From hundreds of pages to Security Objectives in seconds.

Manual DO-326A analysis costs certification programmes months of qualified engineering time. CompliAir eliminates that bottleneck without compromising rigour.

How it works.

01

Ingest your documentation

Upload system architecture documents, safety assessments, ICD specifications, and design artefacts. CompliAir processes natural language, structured tables, and technical diagrams natively.

02

LLM-driven Security Objective extraction

Our aviation-tuned LLM engine scans documentation and identifies Security Objectives as defined under DO-326A/ED-203A — mapping them to system functions, failure conditions, and affected aircraft domains.

03

Threat condition mapping

Each Security Objective is matched against a structured threat taxonomy aligned with DO-356A/ED-204A methods. Threat conditions are scored using aviation-adapted severity metrics.

04

Audit-ready report generation

CompliAir produces structured compliance evidence packages formatted to EASA and FAA DER review expectations — ready for certification submission without reformatting.

05

Closed-loop, on-premise deployment

Zero data egress. CompliAir runs entirely within your infrastructure. Certification artefacts and design documentation never traverse an external network.
