Comprehensive introduction to aerodynamics applied to different types of modern aircraft, now updated with the latest FAA guidance Flight Theory and Aerodynamics provides an introduction to aerodynamics using practical application to modern aircraft with step-by-step calculations. This fifth edition streamlines content, notably the chapters on aircraft stability, and incorporates updated FAA guidance and figures from the 2023 Pilot’s Handbook of Aeronautical Knowledge as well as other FAA handbooks. A balanced application of introductory physics and meteorology in the first five chapters evolves into an introduction to propeller and jet aircraft propulsion and eventually moves into a broad discussion on the application of physics to aircraft takeoff and landing performance. After the introductory material has been presented, principles from earlier in the textbook and prior coursework are correlated and applied to slow flight, aircraft stability, and high-speed flight. A new chapter on Unmanned Aerial Vehicle (UAV) flight theory is included. The text features extensive instructor resources including detailed PowerPoint slides for each chapter, step-by-step guidance for end of chapter calculations, sample test bank questions for each chapter, and application sections within each chapter that allow the instructor to challenge the student with additional real-world scenarios based on chapter content. Flight Theory and Aerodynamics includes information on: In addition to degree-oriented college programs, this latest edition of Flight Theory and Aerodynamics is also an essential resource for pilot training programs ranging from student pilots to flight instructors as well as practicing professionals flying a wide range of aircraft.
