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...

The need of stick force stability for attitude-stabilized aircraft. Part II

A description is given of flight tests related to the effect of various levels of (artificial) positive stick force stability on the longitudinal controllability in the landing approach of an attitudestabilized aircraft. Approach performance and pilot commentary of 60 ILS/VASIS approaches flown with a twin-engined jet transport have been...

The need of stick force stability for attitude-stabilized aircraft. Part 1

After introductory background information on the landing approach piloting task and some arguments for expanding the knowledge on handling quality criteria for certain advanced transport designs, results are given of flight tests related to the effect of positive stick force stability on the longitudinal controllability in the landing approach...
