Criteria for Low-Speed Longitudinal Handling Qualities

In-fl ight simulation experiments performed in 1967 with a variable-stabil ity aircraft during the author''s stay at Princeton University, motivated the study of handl ing characteristics of future transport aircraft with closed-loop fl ight control systems. In 1972, the first experiment took place at the National Aerospace Laboratory NLR, using one of its research aircraft. In anticipation of exp...
