| Abstract | Two qualified test pilots performed a target tracking flight task on a Bell 205 helicopter. Cooper-Harper handling quality ratings confirmed that pilot compensation was proportional to task difficulty. Pilot control activity was measured using the Dynamic Interface Modeling and Simulation System Product Metric (DIMSS-PM) to quantify the number and amplitude of control deflections during each trial. Inter-beat interval measures of heart rate and heart rate variability were also computed to evaluate the pilot’s autonomic nervous system (ANS) response to task workload. The DIMSS-PM was positively correlated with task difficulty, as expected based on the dynamics of target motion for each difficulty level. By comparison, the mean and high-frequency (HF) variability of heart beat intervals were negatively correlated with task difficulty, suggesting an increase in ANS arousal with increased pilot workload. Pilot-specific differences were found in the time-dependent relationship between DIMSS-PM, mean heart beat interval, and HF variability, indicating that control activity and heart rate metrics provide asynchronous and complementary information about pilot workload during helicopter flight. |
