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. No fixed timetable: students progress at their own pace within the intake, which allows them to combine it with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is Advanced Excel (measurements and clearances), PicoScope (ignition diagnosis), MegaSquirt TunerStudio (mixture analysis), Fusion 360 (gaskets and parts), in free, academic or evaluation versions. Tests are studied using real procedures for measuring cylinder, piston and clearances, crankcase gas-tightness testing and controlled bench running-in. Assessment is continuous per module plus the final integrating project.

Accredited laboratories(EN ISO/IEC 17025) with a rotor test rig, EMC/Lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-driven Master's Thesis:safety case, test plan, compliance dossier and operating limits.
Industry-mentored: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, with cyber-OT, DIH and compliance as its pillars.

FAQ

Frequently asked questions

The programme comprises 300 hours in total, spread over 3 to 5 months. That is an average of 10 to 15 hours per week, compatible with a full-time job.

Work is carried out with Advanced Excel (measurements and clearances), PicoScope (ignition diagnosis), MegaSquirt TunerStudio (mixture analysis) and Fusion 360 (gaskets and parts). Free, academic or evaluation versions are used, and the tutor indicates the free alternative where one exists.

An own diploma from SEIUM Institute upon passing continuous assessment and the integrating project. It is in-house training, not an official Ministry qualification.

Yes. Modules passed in a course or postgraduate diploma in the same area are recognised in the advanced programme. Check the recognition policy when you enrol.
