Situational Interactive Micro/Graphic Simulator System for Improving Maintenance Performance.
Abstract
A generic hardware trainer tester was constructed using a microcomputer, two image storage/display devices, a magnetic and reader, a data entry keypad, and a printer. Problem-solving courseware was developed based on situational interaction techniques. Thirty problems simulated troubleshooting the major components of the FB-111A flight simulator. Students solved each problem by forming their hypotheses about the source of trouble, abstracting data from the displays/test instruments they chose to observe, and reformulating their hypotheses as needed. They completed the problem-solving process by replacing the malfunctioning part and verifying that this replacement cleared all symptoms. Some problems were multiple malfunctions. Fifteen newly assigned personnel had to find and correct malfunctions placed in the actual equipment, given only the AFTO Form 781 work order which stated a symptom of the problem. The six personnel with trainer tester experience solved all problems. The nine personnel without the simulator experience solved about half the problems. The simulator-experienced personnel solved the problems in half the time the others did. More than half the simulator-experienced personnel were consistent in taking steps that led directly to problem solution. None of the personnel who lacked simulator experience were consistent; all took irrelevant steps. Job supervisors look for consistent performance before trusting performers to avoid damage to themselves or the equipment. In effect, the simulator training reduces the time it takes new personnel to become consistent job performers.
