These instructor materials for an aviation maintenance technology course contain five instructional modules. The modules cover the following topics: determining the relationship of voltage, current, resistance, and power in electrical circuits; computing and measuring capacitance and inductance; measuring voltage, current, resistance, and continuity; reading and interpreting electrical circuit diagrams; and inspecting and servicing aircraft batteries. Each module contains some or all of these nine basic components--a module introduction and objective, performance objectives, instructor's module implementation guide, technical information supplements, workbook supplements, project guides, theory test, answers to theory test and workbook supplements, and a practical test. These materials were developed through a cooperative effort of airframe and powerplant mechanics, general aviation industry representatives, Federal Aviation Administration representatives, and vocational educators in Oklahoma to provide a comprehensive program in aviation maintenance technology.
