The results of an in-flight investigation of the short-period handling qualities requirements for the up-and-away portion of the mission of a wheel-controlled airplane with a low to medium load factor are reported and discussed. Two groups of configurations with constant short-period damping were investigated. A brief study was conducted to determine the effect on the airplane handling qualities of variations in stick motion per normal acceleration and the PIO tendencies resulting from a reduction in short-period damping. The results are presented in terms of pilot rating and pilot comment data. Comparisons with the proposed Recommendations for Revision of MIL-F-8785 (ASG) 'Military Specification - Flying Qualities of Piloted Airplanes' are made and the data are correlated with various suggested short-period handling qualities criteria. The vehicle used for the in-flight evaluation was a three-axis variable stability T-33 equipped with a wheel controller. (Author)
