Methodology, software & labs

How you'll learn

100 % online training on the SEIUM Institute campus, with downloadable material, recorded classes and a dedicated technical tutor. No fixed timetables: students progress at their own pace within the intake, making it possible to combine the course with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is Advanced Excel, Gas analyser with logging software, Innovate LogWorks, SU needle profile charts (needle profile sheets), in free, academic or evaluation versions. Tests are studied using real carburettor synchronisation procedures with an air flow meter, reconstruction of constant-depression carburettors, and mixture adjustment with a gas analyser. Assessment is continuous, module by module, plus the final integrating project.

Accreditable laboratories(EN ISO/IEC 17025) with a rotor rig, EMC/Lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-oriented Master's Thesis (final project):safety case, test plan, compliance dossier and operating limits.
Industry mentoring:lecturers with experience in training, , eVTOL/UAM and flight test.
Flexible format(hybrid/online), international cohorts and support from SEIUM Career Services.
Ethics and safety:a safety-by-design approach, OT cyber-security, DIH and compliance as its pillars.
