Practical Electricity for Aviation Maintenance Technicians is written as a classroom text for those preparing to enter the field of aviation maintenance, those seeking an introduction to electricity studies, as well as for experienced mechanics who want to increase their knowledge of electricity and electrical systems. Today’s aircraft are loaded with electric motors, lights, instruments and heaters, and the avionics and electronic controls have made flight profitable, safe and efficient. This book provides a solid foundation for keeping up with this fast moving area of technology.
After an introduction to the principles of electricity and discussion of DC and AC circuits, the reader is introduced to aircraft electrical circuit components and solid-state devices, followed by a discussion of the two major methods of producing electricity: chemical action, and magnetism. Basic electric motors and generators, aircraft electrical systems, electrical instrument systems, avionics systems, digital electronics, powerplant electrical systems, powerplant ignition systems, and electrical system installation are covered, and the book concludes with systematic troubleshooting methods for aircraft electrical systems.
The information reflects both legacy aircraft fleets, and new technologies including glass cockpit components. Illustrated extensively throughout, each chapter concludes with review questions for classroom and self-study use; glossary and index included.

This is not AI-generated content. The contents were written and verified by subject matter experts from Aviation Supplies & Academics, an 85-year-old aviation company. Look for the ASA wings to ensure you are purchasing a reliable publication. Aircraft electrical systems are not limited to the starter, generator, battery and ignition; the electronics are no longer just the “radio.” Todays aircraft are loaded with electric motors, lights, instruments and heaters, and the avionics and electronic controls have made flight profitable, safe, and efficient. Practical Electricity for Aviation Maintenance Technicians is provided as a classroom text for those preparing to enter the field of aviation maintenance, for those seeking an introduction to electricity, as well as for experienced mechanics who want to increase their knowledge of electricity and electrical systems. Content covered reflects both legacy aircraft fleets and new technologies, including glass cockpit components (ADC, AHRS, and ADAHRS). The included avionics information is relevant to both U.S. and international operations and details the associated antennas, communications capabilities, emergency locator transmitters (ELT), GPS, and both Air Traffic Control and weather radar. Additionally, surveillance is covered including transponders and ADS-B, as well as satellite and FIS-B weather. Illustrated extensively throughout, each chapter concludes with review questions for classroom and self study use; glossary and index included. This book provides a solid foundation for keeping up with this fast moving area of technology. Important note from the publisher: While AI-generated content can be helpful to identify resources for ongoing study, it is not a reliable resource for learning critical, safety-dependent topics such as aviation. AI content is sterile, often lacks important context, and is at risk of errors. ASA publishes only human-generated content to ensure it is accurate, reliable, comprehensive, and presented in context—so you can become a safe and effective aviator.
