I'm a pilot, but I've never found any previous explanations of LIFT to "feel right." Someone asks you how an aircraft is able to fly, and you start off with the classic curved wing / half-venturi story, with acceleration of air over the top wing surface leading to a pressure differential between top and bottom wing surfaces, and Quod Erat Demonstrandum - YOU'VE GOT LIFT! Then that someone invariably asks, "Then how is it that an aircraft can fly upside-down? Wouldn't that same LIFT above the now-upside-down bottom wing surface push the aircraft towards the ground?!" Great Question, eh? That question has led me to stop explaining what I obviously don't know (and what sounds like Voodoo or Quantum Mechanics coming out of my mouth).

I've found the explanations in Understanding Flight very digestible, and with the right amount of detail; I've long wanted a good explanation of how my Cessna flies, and the relationship between an aircraft and the forces at work. I've read the authors' Bios, and I've got to believe they truly understand Flight. It sure would be nice if they could work on an updated version of Stick and Rudder! I'm sure Wolfgang would be pleased. :)

What are you looking for?

This book is written by very accomplished aeronautical industry/academic professionals. Do you want their insights? Or, do you want their formulae?

Many want the formulae, but I wanted the insights. And that is exactly what this book provides.

If you are looking for a fresh, experienced, and non-dogmatic view of the principles of flight then this is the book for you.

You'll get it as soon as you get through about 20 pages. This isn't your sad physics teacher's regurgitation text on flight. It is real and begins to point light on lift and aerodynamics for those of a more philosophically curious nature.

Simple, straight-forward, and with the gravity of experience. Excellent.

I purchased this book for my daughter, who is 13 and enamored with flight. She has spent hours with the book. The pictures and drawings help bring the topics down to an understandable level for all ages.

The book starts with a non standard approach to describing lift forces on a wing. The authors attempt to explain the lift processes in terms of power rather than the more conventional approach of differential pressure induced by fluid flow around an object. They use the terms induced power and parasitic power rather than introducing the more conventional terms of induced drag and parasitic drag. Of course all of these variables are mathematically related just as one can derive the differential pressure changes from the momentum changes of the airflow over a wing. Aerodynamicists know that the reality of lift and drag phenomena is very complex and is only rigorously modeled by understanding the mathematical interrelationships between energy and momentum exchanges of huge numbers of molecules and surfaces and the intermolecular forces that determine fluid viscosity.

A problem with the approach is that it does not directly lead to the simplified mathematical relationships resulting from changes in drag coefficients and the reader is not really introduced to the standard nomenclature used by the aeronautical community. Few basic equations are really used either. The reader is also subjected to many "factoids" that are not really related to the subject material being discussed. The later chapters also stumble in explaining lift augmentation devices and propulsion systems due to the unconventional introduction. As an engineering educator, I came away from the book with a feeling that the book fails to provide the reader with background to further delve into the subject matter. I have read better introductory books such as Smith's Illustrated Guide to Aerodynamics.

I think this is the right book to start the investigation of flight. It is well written and structured. It explains the theories of flight in simple and easy to understand terms. This is not a text book for scientists but it does exactly what the title says. I am thankful that I purchased it because I have ten other books that just led me to being more confused and now, because of this book I am confident of my knowledge of flight.
