These military-developed curriculum materials consist of four volumes of individualized, self-paced texts and workbooks for use by those studying to become aircraft pneudraulic repairmen. Covered in the individual volumes are the following topics: pneudraulic functions and career program (housekeeping and safety practices, hydraulic fluids and plumbing materials, and maintenance tools); operation and maintenance of pneudraulic components (pneudraulic terms; pneudraulic systems supply units; pressure-regulating, limiting, and controlling devices; flow control and directional units; landing-gear components; and brake systems components); pneudraulic systems and principles of operation (pneudraulic power systems, hydraulic actuating systems, and aircraft emergency pneudraulic systems); and ground equipment, schematics, and supervision and training (shop and aerospace equipment and the use of hydraulic schematics). Each chapter contains objectives, readings, review exercises keyed to the text, and answers to the exercises. (MN)
