Module 3 Electrical Fundamentals: Cat A1 Exam Manual

Module 3 · Cat A1 · 7 syllabus subjects

Executive overview

Module 3, Electrical fundamentals, asks candidates to master direct and alternating current theory, circuit laws, passive components, generators, motors and transformers. 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 7 syllabus subjects of Regulation (EU) 2023/989, Part-66 Appendix I: 7 at Level 1. 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 3 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 solve series, parallel and combined circuits step by step, work out AC phase, reactance and power relationships and explain how aircraft generators and motors turn energy.
  • It confronts the classic stumbling block head on: AC calculations with reactance and phase angle.
  • Expect circuit problems that reward a clean method more than speed; the chapter order follows the syllabus so you can tick subjects off as you go.

Competencies targeted (EASA Part-66 syllabus)
