This handbook FAA-H-8083-25C is current in 2026. Providing basic knowledge essential for all pilots, from beginning students through to the advanced certificates, this Federal Aviation Administration (FAA) publication introduces readers to the broad spectrum of knowledge required as they progress through pilot training. Studying this book, pilots gain the required knowledge to earn a certificate and understand the aerodynamic theory associated with flight. Written for the pilot preparing for a Remote, Sport, Recreational, Private, Commercial, or Flight Instructor Pilot Certificate, it is a key reference containing all the information necessary to operate an aircraft and to pass the FAA Knowledge Exam and Practical Test (checkride). This invaluable learning tool begins with a basic introduction to flying and a history of flight and then explores the role of the FAA, the criteria for earning the various pilot certificates, how to select a flight school and instructor, and the tests associated with earning a pilot certificate. Topics covered include aeronautical decision-making, aircraft construction, principles of flight, aerodynamics of flight, flight controls, aircraft systems, flight instruments, flight manuals and other documents, weight and balance, aircraft performance, weather theory, aviation weather services, airport operations, airspace, navigation, and aeromedical factors. Appendices provide additional support including acronyms, abbreviations, NOTAM contractions, airport signs and markings, a glossary, and an index. This 2023 edition reflects the latest aviation industry procedures, equipment, techniques, regulations, and National Transportation Safety Board (NTSB) recommendations and presents an up-to-date resource for the FAA Airman Certification Standards (ACS). Changes include updates to drugs and their impact on flight, nontowered airport operations, and attitude indicator pitch and bank limitations. Complete with chapter summaries and illustrated throughout with detailed, full-color drawings and photographs, this handbook functions like an “aviation encyclopedia” to expand pilot knowledge.
