Training in maintenance skills has become increasingly more important as the cost of replacement parts and expenditures for maintenance personnel have risen. More effective and efficient skills training has been identified as a means to limit costs through fewer false repairs, shorter down time, and decreased numbers of personnel required for maintenance. Advocates have championed various systems and devices for this training, to include in different forms: actual equipment, flat panel simulators, three-dimensional simulators, videodisc, and computer assisted instruction. This paper discusses the integration of interactive videodisc, computer generated images, and three-dimensional simulation in a total system concept for maintenance skills training. Different types of maintenance skills are identified, along with the methods and techniques for training those skills. Implementation of the methods and techniques in an integrated system is presented, to include the means for providing modeling, drill and practice, cueing and prompting, feedback, and evaluation. Two different systems are identified, rationale for the differences is provided, and the advantages each has in intended use is specified.
