The Cambridge Aerospace Dictionary, first published in 2009, is an authoritative and accessible reference useful to scholars and enthusiasts alike. This dictionary is an essential tool for professionals involved in the aerospace industry and flight, and for anyone who must read and understand the technical literature of the aerospace industry and about specific air and spacecraft. It is also an ideal reference for engineering and physics students encountering a subject replete with technical jargon and acronyms. Bill Gunston, one of the most widely read and respected aviation writers, has added more than 5000 new terms and acronyms to this carefully updated volume. Terms used in the dictionary reflect the diverse and international nature of the aerospace materials and organizations. Gunston has scrupulously avoided terms specific to manufacturers, airlines and armed forces in an effort to encourage clear communication and understanding among professionals.
