Abstract : Three pilots performed 102 evaluations of various combinations of variables at a representative STOL approach condition of gamma = 7.5 degrees, V = 65 kts. During the evaluations, a qualitative separation of ambient turbulence level was made through approximate measurements from the aircraft. The configuration dynamics were identified and verified with a digital identification technique developed for the X-22A, and data analyses include statistical measurements of pilot workload and performance, as well as correlation of pilot rating data with these measures, the configuration dynamics, and the roll control power available.
