Certification is a continuous process that connects design, testing, compliance, and approval from the beginning of a program. The key challenge is not only to produce technical data, but to turn that data into a defensible evidence asset that meets authority expectations.
At Aeroset, we support initial and supplemental certification programs by connecting flight testing, data acquisition, engineering work, and regulatory requirements into one structured process. Our role is to ensure that modifications are not only technically sound, but also supported by clear, traceable, and certification-ready evidence. By aligning test campaigns, data, and documentation with the intended approval path, Aeroset helps reduce rework, avoid compliance gaps, and make the certification process more predictable.
Our Contribution to Certification Programs
Certification requires coordinated work across testing, data handling, and compliance. Within this process, Aeroset contributes:
- TC and STC compliance strategy support
- EASA and FAA means-of-compliance alignment
- Qualified flight test pilot support
- Compliance Verification Engineer support
- Certification flight test readiness and risk review
- Technical substantiation and compliance evidence preparation
- Authority-facing documentation and reporting support
Our certification experience is rooted in hands-on aviation engineering work rather than abstract consulting. Aircraft certification is not just a final approval step; it is a structured engineering program that connects design intent, test evidence, and authority expectations from the first planning meeting through the final compliance package. Aeroset supports operators, OEMs, modifiers, and simulator stakeholders with a partner that can move confidently between technical detail and regulatory discipline. We help define certification strategies, translate requirements into executable test activities, and keep deliverables aligned with the intended approval path. In practice, this includes accompanying flight tests, preparing test cards, defining parameter sets, performing data post-processing, and modelling aircraft behaviour in line with EASA and FAA expectations. With expertise in Level D data packages, authority-oriented qualification support, subjective test protocols, and validation data roadmaps, we provide practical capability across the full chain from aircraft data gathering to qualification evidence.
For customers, that means working with a partner that understands both the cockpit and the compliance package. Real certification work involves operational constraints, airport limitations, instrumentation challenges, aircraft availability, and the coordination of multiple stakeholders under schedule pressure. Aeroset helps manage this complexity by ensuring that flight test activities, data outputs, and documentation remain connected to the approval path from the beginning. We know that the value of a flight test campaign is realized only when its results can be transformed into clear, traceable, and review-ready evidence. Our role is to make that path more predictable, more technically robust, easier to audit, and more efficient from initial planning through final approval support.

What Is Initial and Supplemental Certification Support
Initial and supplemental certification support connects aircraft design, modification, testing, compliance demonstration, and final approval into one controlled process. For type certification, the focus is on demonstrating that a new aircraft or major design baseline meets the applicable certification basis. For Supplemental Type Certificate programs, the focus is on proving that a modification can be safely integrated into an already certified aircraft and used in daily operation.

STC and Aircraft Modification Support
Supplemental Type Certificate programs create real value when a modification becomes approved, repeatable, supportable, and useful in everyday operation. In business aviation, STCs are often used to modernize proven aircraft platforms without replacing them, improving capability, passenger experience, crew interface, dispatch reliability, performance, or long-term asset value. Common STC categories include cabin connectivity installations, glass cockpit retrofits, avionics upgrades, aerodynamic improvements, winglet programs, engine-related performance upgrades, and system modifications that affect aircraft operation or supportability.
These programs are much more than installation projects. A connectivity STC, for example, must address aircraft integration, structural and electrical interfaces, electromagnetic compatibility, environmental considerations, cabin installation constraints, downtime, and long-term maintenance impact. Glass cockpit and avionics retrofit programs require careful alignment between displays, flight management systems, autopilot behaviour, alerting logic, crew procedures, training implications, and approved documentation. Performance-related STCs, such as aerodynamic or engine upgrades, must demonstrate measurable operational benefit, whether through improved climb performance, cruise efficiency, range, field performance, or mission flexibility.
Aeroset supports the flight test and evidence-generation side of STC programs where controlled data, aircraft behaviour validation, and certification-ready documentation are required. Our role is to help define the data needed for approval, support the flight test campaign, capture the required parameters under controlled conditions, and prepare the resulting evidence for downstream engineering and certification use. This is especially important when a modification affects performance, handling qualities, systems interaction, operating procedures, aircraft limitations, or approved documentation. By combining flight test discipline with a clear understanding of certification expectations, Aeroset helps ensure that modifications are not only installed, but also validated, documented, and usable within an approved operational framework.

EASA and FAA Compliance Support
Successful certification support requires understanding not only what must be demonstrated, but also how authorities expect evidence to be structured, documented, and presented. Aeroset works at the intersection of engineering, flight testing, data processing, and qualification, supporting programs that need to align with both European and US certification expectations. Instead of treating campaign planning, instrumentation, flight execution, post-flight analysis, model updates, and reporting as separate work packages, we help structure them as one continuous workflow. This allows the same body of evidence to support engineering decisions, certification submissions, and authority-ready reporting.
For EASA-facing programs, flight test support must be integrated with the approved design and maintenance framework, including coordination with Part 21 design organizations and Part 145 maintenance organizations where instrumentation approval, installation, or aircraft readiness are required. Whether the certification basis falls under CS-23, CS-25, 14 CFR Part 23, or 14 CFR Part 25, the principle remains the same: define the applicable requirements, map the campaign to the agreed means of compliance, capture the right data under controlled conditions, and document the results in a technically defensible way. Aeroset emphasizes clean parameter definitions, disciplined test card preparation, configuration traceability, and rigorous post-flight analysis, helping customers reduce rework, improve consistency across documents, and gain stronger confidence that the data package will support the intended approval path.

Documentation & Reporting
Certification progress depends on the quality of the documentation just as much as on the quality of the flight itself. A well-run program produces more than raw data; it produces records that explain what was tested, under which conditions, with which configuration, and how the results relate to the compliance objectives. Our workflow includes test card preparation and data post-processing. In practice, that means we support the full reporting chain from campaign planning through final technical output
We place strong emphasis on traceability. Parameter naming, units, configurations, aircraft states, and acceptance criteria must all remain consistent across the campaign. When data needs to be reduced, filtered, or transformed into engineering products, that work is performed in a way that preserves auditability. Where programs feed simulator qualification or training-device work, we also support the transition into QTG and MQTG documentation, helping customers move from measured aircraft behaviour to structured qualification evidence without losing the thread of compliance.
Just as importantly, we help turn technical material into usable authority-facing documentation. That includes reports that are clear enough for reviewers, rigorous enough for engineering teams, and structured enough to support future updates. Good reporting shortens review cycles, reduces clarification rounds, and improves the long-term value of the test campaign because the evidence remains understandable long after the last flight has been completed.
