Module 15 Gas Turbine Engine: Cat A1 Exam Manual

Module 15 · Cat A1 · 18 syllabus subjects

Executive overview

Module 15, Gas turbine engine, asks candidates to master turbine engine theory and construction: inlets, compressors, combustion, turbines, exhausts, fuel and oil systems, starting and ignition. It is pitched at Category A1 depth, where recognition and understanding of line-maintenance tasks come first, so every chapter of this secure ebook is selected for Cat A1 candidates and nothing is padded with content outside your category.

The edition maps to 18 syllabus subjects of Regulation (EU) 2023/989, Part-66 Appendix I: 16 at Level 1, 2 at Level 2. That split tells you where to spend your hours, since Level 3 subjects are examined in the greatest depth.

Study it alongside the Quiz Engine: each syllabus reference in this manual is a Quiz Competency, so you can practise one subject at a time, then run a timed simulation of the Module 15 examination. Your Online Senior Instructor uses the same references to send you back to the right chapter.

How it helps you pass the exam

  • After the manual you can follow air and gas through the engine, station by station, explain why compressors surge and how engines avoid it and link engine indications to the condition of each section.
  • It confronts the classic stumbling block head on: thermodynamic cycle questions and engine-limit reasoning.
  • Expect balanced theory and construction questions across the whole engine; the chapter order follows the syllabus so you can tick subjects off as you go.

Competencies targeted (EASA Part-66 syllabus)

18 syllabus subjects, each shown with the knowledge level examined for the licence scope of this product. Level 1 is familiarisation, Level 2 is general knowledge and Level 3 is detailed knowledge.
