The application of active control technology concepts and in particular the relaxed static stability principle to certain categories of transport aircraft is addressed. Approach and landing flight simulation investigations were performed, using a moving-base flight simulator with simulated outside view. A jet transport conceptual aircraft developed around the relaxed static stability concept and equipped with a primary flight control system of the rate-command/attitude-hold type for pitch and roll control was simulated. Boundaries for satisfactory handling qualities were established from pilot/aircraft performance, pilot ratings and pilot commentaries for a number of handling quality criteria. A criterion on closed loop resonance and pilot compensation (Neal-Smith criterion), related to the pitch attitude control loop is identified as the best format for short period pitch dynamics.
