The author explains how the characteristics of an airplane affect pilot ability to complete tasks, response factors, stability and damping of the airframe to changes in angle of attack, basic stability, trim, control forces, and control power. He also addresses the controversy behind the design of airplanes, their characteristics and the resultant suitability for various types of flying;
