This book follows the path of other books concerning the design of gliders and light airplanes already published by IBN Editore in Italian and in English.
Writing this book, “Light Airplane Static and Dynamic Stability”, my intentions were pragmatic but my intention was also to propagate the essential knowledge needed to proceed in this part of aircraft design.
Accordingly the content and figures accompanying the text have been prepared mainly for the use of students and amateur designers. Another intention was to make problems of aircraft stability more understandable, as often, in other much more important works,
they are presented in a theoretical way and are sometimes not sufficiently related to the physical reality and needs of designers. The results of the quartic equation solution very much depend on the precision of the calculations. Small variations in the numbers chosen for the derivative values lead to significant changes in the results. Once more I must remind readers that precise calculations of the moments of inertia are of paramount importance as well as the estimation of the derivatives. Anyway the last word in aircraft stability is left to flight tests, but this does not mean that designers may skip dynamic
Calculations provide us with tangible, practical and relevant data about safety and it is better to read them before possibly incurring serious mistakes.
