Methodology, software & labs

How you'll learn

100% online training on the SEIUM Institute campus, with downloadable materials, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme is compatible with full-time work.

Each module combines theory, guided reading of the original standards and applied exercises. The working software is ReliaSoft BlockSim, Isograph Reliability Workbench, MATLAB/Simulink, PTC Windchill Risk and Reliability and Python with NumPy, in free, academic or evaluation versions. Practical work is based on real procedures: reliability modelling of triplex architectures, simulation of cross-comparison monitors and justification of dispatch conditions. Assessment is continuous by module, plus a final capstone project.

Standards covered: SAE ARP4761A / EUROCAE ED-135, EASA CS-25.1309 and AMC 25.1309, SAE ARP4754B / EUROCAE ED-79B, SAE ARP5107B, RTCA DO-254 / EUROCAE ED-80, MIL-HDBK-338B, IEC 61165:2006, IEC 61078:2016.

Assigned technical tutor:every module ends with a deliverable that your tutor marks individually.
Standards-based learning:guided reading of SAE ARP4761A, CS-25.1309 and ARP4754B applied to real cases, not as a theoretical annex.
Industry software:ReliaSoft BlockSim, Isograph Reliability Workbench, MATLAB/Simulink, PTC Windchill Risk and Reliability and Python with NumPy, in free, academic or evaluation versions.
Final project:a justified redundant architecture for a critical avionics function, reviewed by your tutor.
Flexible format:100% online, no fixed timetables, compatible with full-time work.

Frequently asked questions

The programme totals 300 hours over 3 months. You set your own pace within each intake, and your tutor helps you plan the workload around your job.

You work with ReliaSoft BlockSim, Isograph Reliability Workbench, MATLAB/Simulink, PTC Windchill Risk and Reliability and Python with NumPy, using free, academic or evaluation versions. Your tutor indicates the free alternative wherever one exists.

A SEIUM Institute certificate, awarded on passing the continuous assessment and the final project. It is SEIUM's own qualification, not an official state degree; its recognition depends on the programme completed and the regulations of each country.

Yes. Modules passed are recognised in a higher programme in the same area (postgraduate diploma or master's). Ask about the recognition policy when you enrol.

No prior qualification is required; you need an internet connection, a computer able to run the programme software and English sufficient to read technical standards.

Start dates are set by SEIUM's faculty for each intake. Our admissions team will confirm the next available date when you apply.
