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

Task Analysis and Workload Prediction for the MH-47E Mission and a Comparison with CH-47D Workload Predictions. Volume 1. Summary Report

“…The methodology was later refined and used to develop a model of operator workload for the AH-64A aircraft (Szabo & Bierbaum, 1986). Bierbaum, Fulford, and Hamilton (1990) provided a complete description of the TAWL prediction methodology and its computer support.…”

Task Analysis and Workload Prediction Model of the MH-60K Mission and a Comparison with UH-60A Workload Predictions. Volume 1. Summary Report

“…Initially, the methodology was used to address design issues for the Army's Light Helicopter Family (LHX) aircraft (Aldrich, Craddock, & McCracken, 1984;. The methodology was later refined and used to develop a model of operator workload for the AH-64A aircraft (Szabo & Bierbaum, 1986). Bierbaum, Fulford, and Hamilton (1989) provided a complete description of the TAWL prediction methodology and its computer support.…”

“…Four specific indexes of overload, as defined by Aldrich, Craddock, and McCracken (1984) and Szabo and Bierbaum (1986), were computed by TOSS; these indexes of overload are described in the following paragraphs.…”

Task Analysis/Workload (TAWL): A Methodology for Predicting Operator Workload

“…The refined methodology, including equal-interval workload rating scales, has been used to predict the workload in existing and modified versions of the AH-64 aircraft (Szabo & Bierbaum, 1986), UH-60A aircraft (Bierbaum, Szabo, & Aldrich, 1987;Bierbaum & Hamilton, 1990a), and CH-47D aircraft (Bierbaum & Aldrich, 1989;Bierbaum & Hamilton, 1990b). The refined version of the methodology is called the Task AnalysisNorkload (TAWL) methodology.…”
