Human Operator Performance in Hypoxic Stress,
Abstract
The experiment was designed to assess the value of several different tracking tasks in quantitatively measuring the effects of hypoxia on human operator performance. Each subject was required to perform three tracking tasks. One was an adaptive first order unstable task. The second represented stable third order longitudinal airframe dynamics. The last was a two axis combination of the first two, with the stable task represented by the vertical display axis and the unstable task on the horizontal axis. A two by two analysis of variance was employed to provide estimates of the reliability of the measurements. The results indicate that the adaptive unstable task is significantly sensitive to hypoxic stress, whereas to identify similar changes in the stable task requires frequency domain analysis. There is some indication that the unstable task may be sensitive to 12,000 ft simulated hypoxia after only 2 minutes of exposure. (Author)
