The Art and Science of Flying Helicopters covers the fundamentals of helicopter theory, performance, flying, and more advanced aspects of the helicopter itself. Turbine engines, ancillary systems such as hydraulics, and peculiarities of the helicopter are explained in detail with diagrams to aid in comprehension. This manual takes a structured approach to helicopter flying in the areas of aerodynamics, performance, flight techniques, and engine failures, and has both beginners and advanced sections in each of these areas. The division of the book into two parts, for beginners and for advanced pilots, makes it an easy-to-read reference. While performance is covered briefly in the beginners section to permit understanding of how it affects the flight of the machine, it is described in much more detail in the advanced section. Students of both civil and military helicopter flight training and maintenance will benefit from this manual. Numerous examples as well as practical tips for both instructors and students enhance this text and make it a critical addition to any flight training classroom.
