Planning, development, verification, and certification liaison — all under one roof.
Vozwin engineers and auditors with hands-on DO-178/DO-254/DO-278 experience. No outsourcing.
Evidence-driven processes and tool-qualified workflows reduce rework and keep programmes on schedule.
Scaled services for OEMs, Tier 1/2 suppliers, and new market entrants. From full lifecycle to targeted gap work.
Three standards. Full DAL coverage.
Software Considerations in Airborne Systems and Equipment Certification. The governing standard for safety-critical airborne software across all Design Assurance Levels.
Design Assurance Guidance for Airborne Electronic Hardware. Covers FPGAs, ASICs, PLDs, and complex custom hardware for safety-critical avionics systems.
Guidelines for CNS/ATM systems. The DO-178 equivalent for software in ground-based safety-critical air traffic management and communications infrastructure.
Full lifecycle or targeted engagement.
Whether you need full lifecycle ownership or a targeted independent audit, Vozwin scales to your programme.
Development of PSAC, SDP, SVP, and SCMP aligned to your DAL and project scope. Process definition that builds traceability from the start.
Requirements capture, software architecture, detailed design, and coding standards implementation. Evidence-driven from day one.
Requirements-based testing, structural coverage analysis (MC/DC, statement, decision), peer reviews, and independence verification. Tool qualification per DO-330.
Independent SAS readiness reviews, DAS audits for DO-254, and gap analysis against current FAA/EASA/Transport Canada guidance.
Coordination with Transport Canada, FAA, and EASA DERs throughout the campaign. Issue Paper management, SOI audit preparation, and DER coordination.
Hands-on DO-178C, DO-254, and DO-278 training for engineering and management teams. Practical workshops covering objectives, evidence, and common DER findings.
We engage at any phase.
Most programmes benefit most from early involvement. We can also step in mid-stream for gap work, audits, or DER support.
Built for aerospace programmes of all sizes.
Full lifecycle certification support integrated into your development programme from PDR onward.
Component-level DO-254 and DO-178C support for avionics hardware and embedded software deliverables.
UAV manufacturers and eVTOL startups — we help teams unfamiliar with certification navigate the process without costly missteps.
DO-278 compliance for ground-based safety-critical software in air traffic management and communications infrastructure.
We Build the Systems.
We Certify Them Too.
Most certification consultancies advise from the outside. Vozwin builds avionics and UAV systems — which means our engineers understand what certification requirements look like from inside a real development programme, not just from a checklist.
That gives us a practical advantage: we know where programmes lose time, where evidence gaps appear under DER scrutiny, and how to structure a compliance argument that holds up through Stage of Involvement audits.
Vozwin's own engineers and auditors — not subcontractors. You get the same people on calls as you get in the reviews.
A DO-178C process built correctly at PDR costs a fraction of a retrofit. We help you build it right the first time.
Evidence-driven workflows with qualified tools under DO-330 — reducing rework and strengthening your SAS.
Transport Canada, FAA, and EASA. We navigate the differences so you don't have to learn three certification regimes.
