"Gudmundsson has set a benchmark for textbooks on aircraft design. Within its declared bounds this book is remarkably comprehensive, with introductory material, clearly presented mathematical tools with assumptions and derivations, notes on when and where to apply them and numerous real-world examples. Gudmundsson truly has a feel for design, something he tries to convey throughout, describing each task, the nature of the designer’s approach and the wide-ranging set of constraints to be addressed. As well as all the analytical work described above, aircraft design requires graphic skills. A real pleasure in this book is the high quality of the illustrations; Gudmundsson is right to be proud of them. Of the many textbooks on aircraft design this is my favourite. The author’s declared aim remained, as with the first edition, to gather information and procedures helpful to the designer. He has achieved this to a very impressive standard. By including all aspects, even organisation and management of the process, he has made this a valuable and comprehensive ‘go-to’ reference source." --John M Robertson, CEng MIMechE MRAeS, RAeS General Aviation Group
