INTRODUCTION The increasing use of complex training equipment has called attention to the need for careful planning not only in the selection of training equipment but of the entire training plan. Training experts have in recent years researched this subject and a large number of documents exist describing the process which will produce sound training programs. This AIR briefly describes the major elements of the process and provides a list of significant references with the purpose of encouraging a systematic and sound educational approach to the design of training equipment. The primary purpose of a training program is to teach the trainee the attitudes@ knowledge@ and skill he must possess to effectively perform his job. Training equipment is employed in the student's performance. The selection of specific training equipment depends@ therefore@ on: a. Analysis of the real task in order to define critical@ trainable elements. b. Determination of training equipment characteristics. c. Engineering feasibility study and establishment of design specifications. d. Design and fabrication of training equipment. e. Introduction of training equipment to the user. f. Field evaluation.
