Aerospace MBSE · ARP4754B · SysML in CATIA Magic / Cameo
Senior SysML modelers build the requirements, architecture and interface models your aircraft or spacecraft program runs on, with the trace your certification and review evidence depends on.

Development assurance
SAE ARP4754B guides how civil aircraft and systems are developed: requirements captured, validated, allocated and verified, with every step traceable. A SysML model is the natural place to keep that trace.
Every requirement carries its source and rationale, and derived requirements are flagged so they reach your safety assessment.
Hardware and software item requirements go to your DO-254 and DO-178C teams with the trace back to aircraft functions intact.
When a requirement changes, the model shows what it touches: the design that satisfies it and the tests that verify it.
What we do for aerospace programs
We work inside CATIA Magic / Cameo on your conventions and your schedule, alongside your engineers or on your behalf.
Requirements
Aircraft, system and item requirements in one model, each with a source, a rationale and a trace.
Architecture
Functional, logical and physical architecture, with interfaces modeled once and shown as the ICDs your suppliers need.
Budgets
Rollups and parametric models that recalculate when the design changes, instead of a spreadsheet that drifts.
Behavior
Operating modes and state machines you can simulate in Cameo before hardware exists.
Safety links
Functions linked to the failure conditions in your safety assessment, so safety-driven requirements stay traceable.
Your team
The same senior modelers teach your engineers SysML and Cameo, so the program doesn't depend on us.
ARP4754B integral processes
We set the model up so the evidence each process needs is a query, not a spreadsheet someone has to rebuild before every review.
| Process | What lives in the model | What we set up |
|---|---|---|
| Requirements capture | Aircraft, system and item requirements with source and rationale. | Requirement types and custom columns, imports from DOORS or spreadsheets, derived-requirement flags. |
| Requirements validation | Evidence that each requirement is correct and complete: its source, its parent and its reviewer. | Validation status fields, review tables, gap reports for requirements with no source. |
| Safety assessment | Links from functions to failure conditions and from safety requirements to design. | Profiles for failure conditions, trace from safety requirements to the elements that satisfy them. |
| Implementation verification | A verify relationship from every requirement to its test, analysis or inspection. | Verify coverage matrices, verification method fields, reports of unverified requirements. |
| Configuration management | Which design and tests a requirement change touches. | Change-impact tables, requirement change tracking, baselines in Teamwork Cloud. |
The model holds the trace; your certification plan decides what counts. Certification credit is agreed between your program and the certification authority. We build the model so the evidence your plan calls for is easy to produce.

CameoMagic provided insightful guidance and demonstrated a deep understanding of SysML. They applied it to our domain with ease and efficiency, making the whole process seamless.
Their speed, deep model knowledge, and practical guidance allowed us to deliver a high-quality system model on time, which was ultimately accepted by the government.
Questions
No. We model the aircraft, system and item requirements and hand item requirements to your software and hardware teams with the trace intact. Those teams and your certification specialists own DO-178C and DO-254 compliance.
It can hold the trace and data your evidence is drawn from. What counts is set by the certification plan your program agrees with the authority, and we build the model to fit that plan.
Yes. Small teams often need a working model before they can hire a modeling group. Hour blocks let us start small and your engineers learn as the model grows.
Yes. The same requirement, architecture and verification modeling supports the SRR, PDR and CDR reviews used on space programs.
Tell us up front. We work on unclassified, non-CUI material today and scope export-controlled work around what your program allows.
