The theoretical examination for the Class 2 Unmanned Aircraft System (Drone License), a national qualification, rigorously tests the examinee's accurate understanding of legal knowledge, aircraft systems, operational structure, and risk management for the safe operation of unmanned aircraft. The examination requires a wide range of knowledge essential for pilots, from the latest category operation rules based on the Aviation Law, to aircraft flight principles, battery handling, weather effects, and responses to accidents. This question collection thoroughly analyzes the training manuals of registered training institutions and the latest examination trends, and includes a total of 200 questions covering the key points directly related to passing the exam. It is structured around four pillars: "Regulations," "Systems," "Operational Structure," and "Risk Management," allowing for practice in a format similar to the actual three-choice exam. Detailed explanations are provided for all questions, designed to help you deeply understand the basis for the correct answers. This is the optimal practical study material for those aiming to pass the theoretical examination via the shortest route, as well as for all pilots who want to systematically organize their knowledge of unmanned aircraft safety operations and enhance their safety awareness in practical work. ⸻ Contents of this book • Chapter 1: Regulations related to Unmanned Aircraft (Aviation Law, registration system, prohibited airspace, compliance matters, etc.) • Chapter 2: Unmanned Aircraft Systems (flight principles, airframe structure, communication, batteries, inspection and maintenance) • Chapter 3: Unmanned Aircraft Pilots and Operational Structure (pilot's obligations, flight planning, role of assistants) • Chapter 4: Operational Risk Management (weather effects, radio interference, accident response, risk assessment) • A list of correct answers for all 200 questions and detailed explanations for each question ⸻ Features • Covers the entire scope of the Class 2 Unmanned Aircraft System theoretical examination with 200 questions • Fully supports the three-choice exam format, cultivating practical judgment skills • Provides accurate knowledge based on the latest training manual content (corresponding to the 3rd edition) • Chapter structure makes it easy to identify weak areas, enabling efficient overcoming of weaknesses • Difficult terms related to laws and systems are also firmly established with easy-to-understand explanations
