Rapidly increasing air traffic around the globe, soaring numbers of passengers, security concerns on the ground and in the air, changes in the Air Traffic System, new maintenance and flight technologies, recent accidents, and intensified media focus--all point up the need for greater attention to commercial aviation safety in the third millennium. Built upon the 5-M model--Man, Machine, Medium, Mission, and Management--this text by aviation author Alexander T. Wells integrates the latest research on human factors, technologies, systems, operations, and management strategies into the most comprehensive, up-to-date, and systematic reference on commercial aviation safety in the world.
