This course provides an in- depth study of electrical systems used in turbine- powered aircraft. It covers aircraft electrical power generation, distribution systems, and key components such as generators, alternators, transformers, and electrical control units. Students examine AC and DC systems integration, load management, and protection devices within modern aircraft. The course also addresses system operation, monitoring, and troubleshooting of electrical systems in turbine aeroplanes. Emphasis is placed on understanding system architecture, interpreting technical documentation, and applying safe maintenance practices, ensuring alignment with EASA Part- 66 Module 11 standards.
