* Aircraft Flight Dynamics* is an undergraduate course that presents theory and methods for describing and predicting the motions of aircraft. The course introduces students to the performance, stability, and control of a wide range of airborne vehicles. Attention is given to mathematical models and techniques for analysis, simulation, and evaluation of flying qualities, with brief discussion of guidance, navigation, and control issues. Topics include equations of motion, configuration aerodynamics, analysis of linear systems, and longitudinal/lateral/directional motions.

The slides used as lecture materials are presented here. While the course focuses on the *Science and Mathematics* of flight dynamics, historical antecedents are presented as *Case Studies* in aircraft performance, stability, and control. The science and mathematics component is based on **Flight Dynamics**** (2004)**. The case studies were initially motivated by **Airplane Stability and Control: A History of the Technologies that Made Aviation Possible**** (2002)**, M. J. Abzug and E. E. Larrabee, and they are enhanced by reference to current web-based content. Each lecture is one hour and twenty minutes long.
