Abstract : The role of pilot opinion and rating in defining flying qualities, and the pilot-adapted control behavior that impinges on such ratings are delineated and discussed. This is preparatory to the exemplary application of frequency domain pilot-models to the examination and elucidation of a variety of flying qualities situations/problems. This examination starts with single-loop situations which progress in complexity; and then shifts to multiple-loop cases, which also progress in complexity. This succession is designed to increasingly reveal the basic pilot-centered requirements for good flying qualities. Such requirements, which stem from easily achieved pilot adaption and good resulting closed-loop responses, are more generally applicable to 'new' unknown situations than are classical requirements on the open-loop controlled element dynamic parameters. However, the latter do in fact influence the ease of terms of characteristics in the projected crossover frequency region, may also achieve a degree of generality. The pilot-centered requirements illustrated by the examples, and others found in the literature, are collected and briefly discussed to conclude the lecture. (SDW)
