| 摘要： | Two experiments were conducted to assess the impact of display size on flight control, airspace surveillance, and goal-directed target search. In Experiment 1, 16 pilots completed a basic flight control task under single and dual axis control. Pilots exhibited less path error and greater stick activity with a large-scale display, suggesting that larger depictions of error lead to greater urgency in correcting deviations. Experiment 2 scaled-up findings from Experiment 1 for flight control, hazard surveillance, and target search tasks. Results from Experiment 1 were replicated for the flight control task. Size, however, did not affect surveillance or search because pilots were adaptive in altering scanning patterns in response to increases in display size. Practical implications of these results are that displays should not be minified to fit within cramped cockpits, as such changes will hinder flight control. / NOTE: Technical rept. / Supplementary Notes: Sponsored by National Aeronautics and Space Administration, Moffett Field, CA.
