Link has recently applied state-of-the-art instructor operator station (IOS) technology to an existing full mission training device. An intelligent workstation, designed to focus on the instructor's specific needs for each training task, has been added to an F-16 Full Mission Simulator, replacing an IOS representing an earlier technology. This system was conceived with the participation of the user, taking advantage of past experience with F-16 training requirements and methodologies. The new IOS technology addresses the needs of the instructor to accomplish specific training tasks by providing displays and controls optimized for specific tasks. Windows, color, icons, and merged text and graphics contribute significantly to the system's ability to support the instructor. Maintainability has been enhanced by decentralizing the IOS software in commercial off-the-shelf workstations. Instructors using the system indicate that it is meeting its training design goals, and that it is significantly more effective than the earlier design.
