It is essential for all engineers and practitioners to have a fundamental understanding of cost structure, estimating cash flows, and evaluating alternative projects and designs on an economic basis. Engineering Economics for Aviation and Aerospace provides the tools and techniques necessary for engineers to economically evaluate their projects and choices. Offering a comprehensive understanding of the theory and practical applications of engineering economics, this book explains and demonstrates the principles and techniques of engineering economics and financial analysis as applied to the aviation and aerospace industries. The authors use time value of money, interest, and Microsoft Excel functions to evaluate the cash flows associated with a single project or multiple projects. They use different engineering economics tools to evaluate individual projects or select the best of multiple alternatives. Fully updated to reflect the latest information on, and practical insights into, the field of engineering economics, this second edition of Engineering Economics for Aviation and Aerospace continues to provide students of aviation and industrial economics, as well as practitioners, with the necessary mathematical knowledge to evaluate alternatives on an economic basis.
