Approaches and landings were carried out using an in-flight simulator to validate results of experiments carried out on a ground-based simulator, in which handling qualities of transport aircraft equipped with rate-command/attitude-hold flight control systems were investigated. Results indicate that general trends in ground-based and in-flight results are very similar, but air speed control is more difficult in-flight than ground-based, resulting in higher Cooper-Harper ratings for longitudinal handling qualities in-flight. Improvement in pilot opinion with increasing levels of maneuver enhancement observed ground-based is not as explicit in-flight. The air speed problem was investigated by introducing artificial stick force stability in the system through feedback of velocity error. Control improves slightly but pilot opinions differ considerably on the merits of this addition.
