  2. Evidence Type: Excerpt from Experiment
    Evidence: "The pilots in Experiment Three ended up using the automation an average of 34% more that the students over the entire timeline, and roughly a third of the pilots did not turn the automation off during the failure periods. The dynamic characteristics of the pilots' automation use profile were very similar to those of the students' profile, showing no effect from workload but significant effects from uncertainty and automation reliability. Pilot automation strategies showed somewhat less of a clear pattern based on stated influences than the students' did. Again, no significant correlation was found between manual performance and manual gambles, and there were no significant differences between the two groups in Complacency-Potential Scale scores or measures of risk taking. These conclusions suggest that pilot experience with automation biases them in favor of automatic control, in contrast with the students who showed a bias in favor of manual control." (page 115)
