Aeroplanes in Gusts

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The mathematics, which some pages of the book may appear to contain, will, on inspection, be seen to be hardly more than symbolic arithmetic; and, more over, owing to the use made Of graphical constructions, the physical meanings of the steps of the arguments may Often be followed quite independently of the quantitative work. Since progress in all the sciences has depended, as is well known (though the knowledge is not always applied), upon satisfactory measures being employed for the quantities concerned, the very first duty of this work is to state, in Chapter I., a suitable measure of a gust, or, in other words, the how much of a gust. That done, a great part Of the rest of the book is mere routine work, that, for academic purposes, but not without sacrificing the simple pioneer character of the book, could have been carried much further into details.
