Abstract : The validity of constraining the responses of today's control dominant aircraft to conform to the classic flying qualities criteria derived from stability dominant aircraft experience has been an issue for many years. Introduction of full time visual scene enhancement with sensor fusion, and computer generated/interpreted night scenes, also escalates display dynamics into the arena of flying qualities concern. Integrated flight and propulsion control schemes and direct force controllers have the potential for completely coupling all the sensors with all the controllers to provide any combination of controlled motion from six independently controlled single-degree of freedom systems to a single completely coupled six-degrees-of-freedom system. These new technologies have expanded flight envelopes, reduced drag, increased manoeuvrability, provided the framework for practical gust alleviation and active flutter suppression, and provided flexibility for fault-tolerant, damage- adaptive flight controls. However, the updating of flying qualities criteria has in general not kept pace with these technological changes. The purpose of this symposium was to review flying qualities issues today, and to report progress towards their resolution. The following topic areas were covered: Flying qualities experiences on contemporary aircraft; Flying qualities research; Application of flying qualities specifications; and Flying qualities at high incidence.
