Task Analysis of the UH-60 Mission and Decision Rules for Developing a UH-60 Workload Prediction Model. Volume 3. Function Decision Rules Appendixes F and G
Abstract
A composite scenario was used to conduct a comprehensive task analysis of the mission of the UH-60 helicopter. The analysis used a top-down approach to identify the phases, functions, and tasks for the mission. Nine phases, 34 segments, 48 functions, and 138 tasks were identified. The crewmember performing each task was identified, and estimates of the sensory, cognitive, and psychomotor workload associated with tasks were derived. Estimates of the task times were also derived. The mission/task analysis data were used to develop a computer model of UH-60 crewmember workload. The model used a bottom- up approach to build mission functions from tasks, and mission segments from functions. Decision rules were written to specify the procedures for combining the tasks into functions, and the functions into segments. The model permitted an analysis of total workload experienced by each crewmember in the performance of both sequential and concurrent tasks, as well. Keywords: Man-machine interface.
