A Meta-Analytic Approach for Relating Subjective Workload Assessments with U.S. Army Aircrew Training Manual (ATM) Ratings of Pilot Performance
Abstract
In 1985 Lofaro, using a modified Delphi technique, had subject matter experts (SMEs) generate estimated ratings of the subjective workload imposed by various Aircrew Training Manual (ATM) tasks for several Army helicopters, including the UH-60 Blackhawk. For each task, ratio-scaled estimates of difficulty and time to perform were derived. This research was performed to determine the validity of the UH-60 ATM estimates by correlating them with instructor pilot (IP) ratings of checkride performance from two other unrelated research projects. The other efforts investigated the decay of ATM task-related skills among Reserve and regular Army aviators. A second phase of this project compared the difficulty ratings of ATM tasks associated with UH-60 accidents over FY 1980-1988 with those not associated with UH-60 accidents. A negative correlation between the modified Delphi weights assigned to ATM tasks and IP ratings on these tasks was hypothesized; the hypothesis was confirmed. Analysis of the UH-60 accident data confirmed the second hypothesis.
