Predicting Maintenance Task Difficulty and Personnel Skill Requirements Based on Design Parameters of Avionics Subsystems.

摘要

The relationships among subsystem design characteristics, personnel skill characteristics, personnel skill characteristics, and job performance were investigated for avionics subsystems. A list of design characteristics was established, and functional loops and line replaceable units were selected from ten subsystems representing navigation, flight control, communications, and fire control subsystems. Experienced supervisors identified high and low skill maintenance personnel. These supervisors associated performance times and error probabilities for three maintenance tasks - an easy task, a difficult task, and a complete functional checkout task. Supervisors also rated each task on a scale of difficulty.
