This book covers basic electrical systems and concepts for the aviation maintenance technician, From basic theory to AC and DC generators and motors, each topic is explained in step by step detail. You will learn by understanding concepts, not just rote memorization and you will learn how and why each skill is useful in the day-day tasks of the aircraft technician in an aviation maintenance environment.
This book is fully compliant as EASA Part 66 module 3 for B1 and B2 licenses and has been given approvals by numerous EASA based civil aviation authorities.
