How you'll learn
A 100% online programme on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. You work with Simcenter Amesim, Ansys Fluent, Dymola, MATLAB/Simulink and Simcenter Flomaster, in free, academic or evaluation versions. Tests are studied on real procedures: thermodynamic simulation of an air conditioning pack, analysis of cabin air quality and distribution, and sizing of emergency oxygen systems. Assessment is continuous by module plus the final project.
Standards covered: CS-25 (EASA) / CS 25.831, ASHRAE 161, SAE ARP85F, SAE AIR1168, ASHRAE 55, ISO 7730, RTCA DO-160G, SAE AS8010.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
