ABSTRACT
This chapter serves as an introduction to aerodynamics and theory of flight for subsonic aeroplanes to underpin the study of autopilots and flight guidance systems. By EASA's definition, ‘aeroplane’ means an engine-driven fixed-wing aircraft heavier than air that is supported in flight by the dynamic reaction of the air against its wings. The study of elementary flight theory in this chapter will be of interest for all aircraft engineers, no matter what their trade specialization. In particular, there is a need for engineers to understand how aircraft produce lift and how they are controlled and stabilized for flight. This knowledge will then assist engineers with their future understanding of autopilot and control systems and the importance of the design features that are needed to stabilize aircraft during all phases of flight. The requisite knowledge needed for the successful study and completion of basic aerodynamics, as laid down in Module 8 of EASA's Part 66 syllabus, is addressed by another title in this book series, Aircraft Engineering Principles. Full coverage of aircraft flight control, control devices and high-speed flight theory will be found in another book in the series, Aircraft Aerodynamics, Flight Control and Airframe Structures.
