The immediate commercial application of the TRADE-FQ technology is the development, testing, certification, and safe operation of modern commercial transport aircraft. TRADE-FQ may significantly enhance the certification process that is currently based on existing requirements that do not account for significant augmentation or non-traditional response types that are possible with fly-by-wire flight control systems. The initial target market envisioned for this product will, therefore, be the worldwide commercial aircraft manufacturing industry and related flight test facilities. Secondary markets include the many large aircraft programs within the U.S. Department of Defense including the Air Force KC-X tanker program, the Air Force C-17, the Navy P-8 Poseidon that is based on a Boeing 737-800, etc. This program will lead to a flight-validated TRansport Aircraft Design Elements Flying Qualities (TRADE-FQ) software toolbox that will feature modern requirements developed from existing data and validated with a new flight test database, built-in data reduction tools, and expert system design guidance. The TRADE-FQ toolbox will directly support the Flight and Propulsion Control and Dynamics, Subsonic Fixed Wing Aircraft, topic under the NASA Fundamental Aeronautics program wherein a stated objective is to develop "flying qualities design guidelines for civil transport aircraft and methods for evaluating the flying qualities of concept transport aircraft¬Ö" Beyond this initial focus, the toolbox will also support the NASA Aviation Safety program by providing a means to directly assess aircraft susceptibility to pilot-vehicle system loss of control including pilot-induced oscillations. The toolbox will be designed to support NASA design and test activities including on-line flight/simulator tests as a control room asset and off-line analysis.
