Methodology, software & labs

How you'll learn

100 % online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, making it easy to combine with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is Advanced Excel, Dynojet Power Core, Innovate LogWorks, gas analyser with logging software, in free, academic or evaluation versions. Tests are studied using real synchronisation procedures with multiple vacuum gauges, calibration of jets and emulsion tubes, and dyno testing. Assessment is continuous per module plus the final integrating project.

Accreditable laboratories(EN ISO/IEC 17025) with roller bench, EMC/Lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-driven final project:safety case, test plan, compliance dossier and operating limits.
Industry mentorship:lecturers with careers 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, cyber-OT, DIH and compliance as its pillars.
