A Comprehensive Task Analysis of the AH-64 Mission with Crew Workload Estimates and Preliminary Decision Rules for Developing an AH-64 Workload Prediction Model. Volume 2. Appendixes A-E

Abstract

A composite scenario was used to conduct a comprehensive task analysis of the AH-64 attack mission. The analysis used a top-down approach to identify the phases, segments, functions, and tasks for the mission. Seven phases, 49 segments, 153 functions, and 653 tasks were identified. The crewmember performing each task was identified and estimates of the sensory, cognitive, and psychomotor workload associated with the tasks were derived. Estimates of the duration of each task also were derived. The mission/task analysis data will be used to develop a computer model of workload for AH-64A crewmembers. The model will use a bottom-up approach to build mission functions from tasks and mission segments from functions. Decision rules were written to specify the procedure for combining the tasks into functions and the functions into segments. The model will permit an analysis of total workload experienced by each crewmember in the performance of both sequential and concurrent tasks.
