This course covers the principles of aircraft stability and control, focusing on topics such as static stability, longitudinal and lateral control, handling qualities, and dynamic stability. By the end of the course, students will be able to analyze the stability and control characteristics of an aircraft, understand the contribution of different components to stability, and evaluate aircraft handling qualities. The course teaches skills such as determining neutral and maneuvering points, analyzing forces and moments, and applying small perturbation theory to study aircraft dynamics. The teaching method includes lectures, numerical problem-solving, tutorials, and a flight experiment. This course is intended for students and professionals in the field of aerospace engineering, aviation, or anyone interested in understanding the stability and control of aircraft.
