Abstract:

The results of a combined flight and groundbased dynamic flight simulator study of the handling and riding qualities problems associated with low-altitude, high-speed flight are presented in this paper. Wide variations of the longitudinal stability and control characteristics, which can be considered representative of current and future strike aircraft, were pilot evaluated. The influence of these stability and control characteristics, as well as the effects of lowaltitude turbulence on the pilots terrain following performance, were measured. The results of this comprehensive investigation are presented in terms of iso-opinion and iso-performance boundaries defining the desired and required combinations of stability and control parameters for low-altitude, high-speed flight. These acceptance boundaries are significantly different from the boundaries presently defined in the Military Specifications. Combinations of vehicle and control system characteristics, which tend to become unstable when coupled with the pilots response i.e., pilot induced oscillations, have been defined. Author
