AGK Electrics - Study eBook

This book is a comprehensive guide on aircraft electrical systems, covering topics such as direct current (DC), alternating current (AC), batteries, electromagnetism, circuit protection, semiconductors, logic circuits, electrical motors, and power distribution. It is structured into chapters, each focusing on specific aspects of aircraft electrics, including their principles, components, and applications. Below is a summary of the key topics:

1. Introduction: Explains electrical conductivity, conductors, insulators, and the effects of temperature on conductivity.
2. Direct Current (DC): Covers the basics of DC, Ohm’s Law, resistors in series/parallel, temperature effects on resistance, and electrical power.
3. Batteries: Discusses types of batteries (lead-acid, NiCad, lithium-ion, lithium-polymer), their characteristics, charging, capacity, and safety concerns, including thermal runaway.
4. Electromagnetism: Explains the magnetic effect of current, solenoids, relays, and the principle of electromagnetic induction.
5. Electromagnetic Induction: Describes the working of generators, voltage control, and the differences between DC generators and alternators.
6. DC Distribution: Details busbars, circuit protection (fuses and circuit breakers), and the distribution of electrical power in single and multi-engine aircraft.
7. Static Electricity: Explains static electricity, static dischargers, grounding during refueling, and electrical bonding.
8. Semiconductors and Logic Circuits: Covers the properties of semiconductors, diodes, transistors, and basic logic gates (AND, OR, NOT, NOR, NAND).
9. Alternating Current (AC): Discusses AC generation, single-phase and three-phase systems, frequency, phase shift, and the advantages of AC over DC.
10. Constant Speed Drive (CSD) and Integrated Drive Generator (IDG): Explains the function, monitoring, and disconnection of CSDs and IDGs.
11. Transformers, TRUs, and Static Inverters: Describes the functions of transformers, transformer rectifier units (TRUs), and static inverters in converting and regulating power.
12. Power Distribution: Details the role of busbars, load sharing, load shedding, and the priority of power sources on the ground and in flight.
13. Multi-Engine Aircraft Electrical Systems: Explains the distribution of electrical power in multi-engine aircraft, including load balancing, ECU buses, and the consequences of generator or bus failures.
14. Electrical Motors: Covers the principles of DC and AC motors, types of motors (series, shunt, compound), and their applications in aircraft systems.
15. Objectives: Lists learning objectives for each chapter, aligning with EASA and UK CAA ATPL(A) standards.

The document includes diagrams, examples, and questions to reinforce understanding, making it a detailed resource for aviation professionals and students preparing for ATPL exams.
