This three-volume textbook and three student workbooks for a secondary-postsecondary level course in aircraft electrical repair comprise one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. The purpose stated for the individualized, self-paced course is to provide the theory part of on-the-job training to upgrade an apprentice (semi-skilled) worker to a specialist (skilled level). The course contains basic information and some supervisory training but requires that the student have background in basic electricity and electronics. Volume 1 (seven chapters) covers flight-line safety, major aircraft systems and electrical maintenance and inspection, portable test equipment, electrical circuit functions, solid state control circuits, and application of electron tubes. Volume 2 (six chapters) discusses aircraft batteries and servicing equipment, power system test equipment, DC generator systems, transformer-rectifier power systems, AC generator systems, and motors and inverters. Volume 3 (six chapters) covers landing gear and associated systems, flight control electrical systems, warning circuits, fuel systems, power plant and related control circuits, and utility systems. Workbook contents include objectives, chapter review exercises and answers, and volume review exercises. (YLB)
