The Textbook outlines the theoretical foundations of aircraft aerodynamics and flight dynamics. The main flight modes, the basics of stability, controllability, and the influence of operational factors on them are considered. The textbook are intended for students studying programs related to aeronautical/aerospace engineering, technical maintenance of aircraft and engines. Moreover, this textbook can be useful for students studying under the EASA Part-66 program. 66 Bibliography sources; 200 figures and 3 tables.
