Built for the hangar, not just the classroom

Certify66 is a study platform for the EASA / GCAA Part-66 aircraft maintenance licence syllabus. It covers all 17 Part-66 modules with interactive simulations, mind maps, quizzes and lessons designed to make abstract theory — physics, electrics, digital techniques, aerodynamics — concrete enough to actually retain.

The simulations exist because Part-66 theory is full of ideas that are hard to hold onto from a diagram alone: how pressure falls as airflow speeds up through a venturi, how an RC circuit charges, how a four-stroke cycle actually sequences. Being able to change an input and watch the result closes that gap.

Certify66 is built and maintained by a working aircraft maintenance instructor, and is used alongside — not instead of — approved training organisation (ATO) coursework.
