In-fl ight simulation experiments performed in 1967 with a variable-stabil ity aircraft during the author's stay at Princeton University, motivated the study of handl ing characteristics of future transport aircraft with closed-loop fl ight control systems. In 1972, the first experiment took place at the National Aerospace Laboratory NLR, using one of its research aircraft. In anticipation of expected developments in (digital) fl ight control technology, the research programme following the first experiments was aimed at the establ ishment of quantitative handl ing qual ities criteria. An appreciable part of that programme has been sponsored by the Netherlands Agency for Aerospace Programs (Nederlands Instituut voor VI iegtuigontwikkel ing en Ruimtevaart) and the Department of Civil Aviation of the Netherlands (Rijksluchtvaartdienst). In 1981, a thorough review of the extensive and valuable data gathered was started. The result, presented in this book, was also included in the author's thesis for a Ph.D. degree of the Delft University of Technology. To introduce the reader to the multi-discipl inary field of handl ing qual ities research, introductory chapters are presented on longitudinal aircraft dynamics, closed-loop fl ight control systems using non-mechanical signal transmission, human pilot dynamics, hand I ing qual ities assessment techniques, and the present status of handl ing qual ity criteria.

The design, development, analysis, and evaluation of new aircraft technologies such as fly by wire, unmanned aerial vehicles, and micro air vehicles, necessitate a better understanding of flight mechanics on the part of the aircraft-systems analyst. A text that provides unified coverage of aircraft flight mechanics and systems concept will go a lon

The suitability of an aircraft with respect to human control is determined by its so-called handling qualities. In modern transport aircraft the handling qualities are determined to a high degree by the flight control system. An introduction to the following aspects of closed-loop flight control systems for modern transport aircraft is given: stabilization and manoeuvring functions, candidate implementation forms, (mini-size) manipulators for flight control, and mathematical representations of the airframe/flight control system combination required for prediction and evaluation purposes. Regarding criteria for good handling qualities of transport aircraft the 'terminal flight phases' (take-off, initial climb, final approach and landing) are of prime interest. A treatise on a number of promising quantitative criteria for transport aircraft equipped with advanced flight control systems is given. Two groups of criteria are distinguished: criteria based on the dynamic characteristics of the aircraft alone (six criteria) and criteria based on the dynamic characteristics of the pilot/aircraft closed-loop system (two criteria). In the latter case a quasi-linear describing function for the human controller behaviour is used. (SDW).

"This report presents a series of discussions on selected topics related to the development of VTOL flying qualities criteria. The topics were chosen on the basis of their importance to flying qualities and the potential significance to the Air Force VTOL Integrated Flight Control System (VIFCS) program. The treatment given to the selected topics was aimed at identifying those areas that require further study and research within the scope of the VIFCS program. -- page iii.
