When introduced to the topic of aircraft flight dynamics students discover that it is the essence of aeronautical engineering because it involves the study of the motion--the flight--of the vehicle. This motion defines the vehicle's performance, a topic of enormous significance to the ultimate success of the machine. Flight dynamics is a study of the complete vehicle, rather than just a component of a vehicle. Hence, it is fundamentally the study of a multicomponent system and its dynamics and control. Modern Flight Dynamics is a result of the author's 30--years of experience in teaching flight dynamics, plus his years of experience as a practitioner and researcher in the field.
