The new edition of this classic textbook, used by universities, training schools, industry and enthusiasts, has been extended to feature a number of new studies in practical aeroplane design.

Mathematics - which general readers may skip - is the minimum needed to work out common sense shapes, aimed at meeting the certification requirements of the three world airworthiness authorities: FAA (USA), British CAA and European JAA. Land and seaplanes are included, from microlight and commuter, to a 30-seat surface-effect (ekranoplan) regional transport, to satisfy specific markets. A new chapter, on "Using the back of an envelope", shows how to make "ballpark" technical judgements.
