Unmanned Aerial Systems: The Definitive Guide was written to provide a comprehensive textbook for training in the emerging technology of unmanned aerial vehicles. These vehicles share many commonalities with manned aircraft, but have unique characteristics that require knowledge and skill to approach safely. Purdue University Professor Michael Leasure provides a comprehensive practical knowledge base on all aspects of unmanned aerial systems (UAS). Professor Leasure's approach to the field and comprehensive coverage of difficult to understand concepts is key in guiding you to a successful career in this emerging aviation segment. Unlike other books that treat UAS as radio control toys, this book provides you with the knowledge that you will need to tackle this field professionally.
