The first thing to say about this book is get the 2nd or later edition. I contacted the author who is approachable and friendly, but he agrees that the later editions are improvements. The main area that caused me to contact him was a confusion between the Koanda effect and viscocity and, as a student of the subject and therefore still researching, it would appear that the Koanda effect does not occur naturally (i.e. without additional aid)and this issue is dealt with in later editions. The book deliberately avoids complex maths and uses prose to get the message across which is that Bernoulli's theroem is not the cause of lift, but the more plausible downwash of air from a wing moving with angle of attack in an airstream. He employs the equal and opposite reaction of Newton's 3rd Law of Motion, which after all must be the primary mover in propellers, turbojets and props and helicopters, all of which employ aerodynamics similar to that of the wing. It may be that Bernoulli's theroem does apply primarily as other authors agree, but for me the simple explanation is the one I have adopted. The book isn't complex and covers a wide range of subjects in digestible lumps, with drawings and photos to amplify. It is a good read and you feel a sense that the author is talking to you and is not remote or superior. However it would need to be supplemented for serious study with books that go deeper into the subject and from authors that have different views on how these things work. As such it is a basic introduction and I can recommend it with the proviso that serious students read as many different books on this complex subject in order to get a balanced view of what is really happening around an aeroplane's wing. The book doesn't always stay open at a selected page when placed on a desk, which is frustrating and due to it's relatively cheap manufacture, compared to other books by this publisher..
