520 ‡aThe systems-analysis theory of handling qualities (which describes the pilot's adaptive behavior in closed-loop operation by servo techniques, and relates his opinion-ratings to his adapted characteristics and the system performance) is used to reveal some important parameters associated with the numerator terms in the airframe longitudinal transfer function. The predictions are verified by five experienced test pilots operating in a fixed-base aircraft simulator. Four possible numerator effects on handling qualities are analyzed theoretically: short-period lead effect on pitch attitude tracking, static-to-short-period gain effects on attitude tracking, short-period lead effects on the control of short-period divergence, and numerator frequency and damping effects on altitude tracking. The results are correlated with other test work, and the implications of these results on future handling qualities research and specifications are discussed.
