In an industry of acronyms and technical language, this comprehensive dictionary is an essential reference book for anyone involved with aviation and/or space organizations—administrators, pilots, maintenance technicians, drone operators, colleges and universities, air traffic controllers, manufacturers, engineers, government agencies, airlines, and corporate flight departments, as well as newcomers to the industry, and those who speak English as a second language. The ASA Dictionary of Aeronautical Terms, now in its Seventh Edition, is a vital reference tool that belongs on every aviation bookshelf.
