Aircraft system development and safety
Development assurance and safety assessment for critical systems, with experts who have built and audited these processes in aircraft programmes.
What we do
Development assurance planning
The plans that set the process before the design starts: system development, safety, software and hardware aspects of certification, with the development assurance levels allocated.
Aircraft and system development process
ARP4754A-based processes for requirements, validation and verification, configuration and process assurance, sized for your organisation.
Safety assessments
Functional hazard assessments, preliminary aircraft and system safety assessments, and the system safety assessment that closes the loop, with the hazard log.
Services for aviation subcontractors
How to work with a design or production organisation as a supplier: the interface, the deliverables and the evidence they will ask for.
Standards
- SAE ARP4754A and ARP4761A, licensed; applied, not quoted
- DO-178C / ED-12C, DO-254 / ED-80, licensed; applied, not quoted
- 14 CFR / CS 25.1309, 23.2510, airworthiness codes
How an engagement runs
An engagement starts with a scoping call and a written proposal that names the deliverables, the standards and the people. Work runs in your tools and your document system, with a weekly status and a single point of contact. Findings and authority correspondence are handled with you, never for you.
Questions
- Do you cover software and hardware assurance?
- The planning and the interface to the safety process, yes. Detailed DO-178C and DO-254 life cycle work is scoped separately.
- Can you run the FHA workshops?
- Yes. We facilitate the workshops with your system engineers and pilots and write the FHA from them.
- Which tools do you work in?
- Yours. We deliver into your requirements and document systems.
- Does this apply to UAS and eVTOL?
- Yes, with the classifications the special condition or SORA OSO #5 requires.
