A research study was conducted to determine the feasibility and desirability of developing generalized training equipment for use in avionic systems maintenance training. The study consisted of a group of survey and analytic tasks to provide useful guidance to serve the needs of the Naval Aviation community in future years. The study had four specific objectives: (1) to assess the extent of maintenance task commonality existing among airbourne weapons systems; (2) to identify new developments and design trends in avionics equipment; (3) to recommend the development of specific generalized training devices; and (4) to describe the general design characteristics of the training equipment recommended. The following tasks were completed and are reported: (a) a survey and inventory of operational aircraft; (b) the selection of a sample of avionics systems; (c) the identification of major task requirements existing for those systems; (d) a survey of new developments in avionics system design; and, (d) a survey of present maintenance practices. Recommendations were formulated for generalized training equipment development: (1) a generalized communication system maintenance trainer; (2) a digital systems training device, augmented for avionics; and (3) a series of generalized devices for teaching lower level maintenance skills.
