Failures in advanced flight control systems of future transport aircraft

Future transport aircraft will be different from to-day's in that they will be designed to be statically neutrally stable or even unstable to improve economics, while the stability will be provided by means of a fly-by-wire flight control system. Since this system will be flight critical it is necessary to develop a philosophy on the treatment...

Low-speed handling qualities of advanced transport aircraft; A comparison of ground-based and in-flight simulator experiments

Determination of low-speed longitudinal manoeuvring criteria for transport aircraft with advanced flight control systems

The application of Active Control Technology concepts and in particular the Relaxed Static Stability principle in certain categories of future transport aircraft will lead to the introduction of primary flight control systems incorporating full-time stability augmentation. For this category of transport aircraft adequate handling quality...

Human pilot describing function, remnant and associated information for pitch attitude control: in flight and ground-based tracking experiments

Servo-analysis techniques, using mathematical models of human control behaviour, are effectively used in studies of the system formed by the human pilot and the flight control system/aircraft combination. Measurement and data analysis techniques for the determination of pilot describing function, remnant and associated information needed in...
