Because the basics are largely unchanging, the book therefore is applicable to large airplanes and small, old airplanes and new, and is of interest not only to the learner but also to the accomplished pilot and to the instructor himself.
When Stick and Rudder first came out, some of its contents were considered highly controversial. In recent years its formulations have become widely accepted. Pilots and flight instructors have found that the book works.
Today several excellent manuals offer the pilot accurate and valuable technical information. But Stick and Rudder remains the leading think-book on the art of flying. One thorough reading of it is the equivalent of many hours of practice.
It may have been first published in the 40s but this book is still timely. The author has a wonderful way of describing the art of flying. Even if you have a good understanding of aerodynamics, this book can still offer refreshing ways of understanding how the airplane behaves. I have been enjoying the book and recommend it.
