In-fl ight simulation experiments played in 1967 with a variable-stabil ity airplane throughout the author's remain at Princeton college, encouraged the research of handl ing features of destiny shipping plane with closed-loop fl ight keep watch over structures. In 1972, the 1st test came about on the nationwide Aerospace Laboratory NLR, utilizing considered one of its study airplane. In anticipation of anticipated advancements in (digital) fl ight keep an eye on know-how, the examine programme following the 1st experiments was once aimed toward the establ ishment of quantitative handl ing qual ities standards. An considerable a part of that programme has been subsidized through the Netherlands company for Aerospace courses (Nederlands Instituut voor VI iegtuigontwikkel ing en Ruimtevaart) and the dept of Civil Aviation of the Netherlands (Rijksluchtvaartdienst). In 1981, a radical overview of the huge and priceless facts accumulated was once began. the end result, awarded during this booklet, was once additionally integrated within the author's thesis for a Ph.D. measure of the Delft college of expertise. To introduce the reader to the multi-discipl inary box of handl ing qual ities study, introductory chapters are awarded on longitudinal airplane dynamics, closed-loop fl ight keep an eye on structures utilizing non-mechanical sign transmission, human pilot dynamics, hand I ing qual ities review concepts, and the current prestige of handl ing qual ity criteria.
