The second edition of Flight Stability and Automatic Control presents an organized introduction to the useful and relevant topics necessary for a flight stability and controls course. Not only is this text presented at the appropriate mathematical level, it also features standard terminology and nomenclature, along with expanded coverage of classical control theory, autopilot designs, and modern control theory. Through the use of extensive examples, problems, and historical notes, author Robert Nelson develops a concise and vital text for aircraft flight stability and control or flight dynamics courses.

The report, based on a detailed analytical effort, provides a realistic appraisal of the capabilities of known gust alleviation systems and determines the feasibility of utilizing these systems in future aircraft intended for sustained low level, high-subsonic-speed operations. Gust alleviation systems are defined as methods which intentionally or inci dentally reduce vertical aircraft loading resulting from atmospheric turbulence. The study considers a number of proposed systems and theoretical techniques. The systems fall into one of two broad categories: feedback control, termed active alleviation and aircraft geometry alteration, termed passive alleviation. Evaluation criteria include alleviation capability, pilot tolerance and endurance, stability, control, performance, structural effects, weight, cost, reliability, and fail-safety. It is concluded that either a normal acceleration feedback system controlling flaps and elevators or a variable sweep wing design offers the most attractive method of obtaining desirable alleviation.
