The present study was designed to assess the influence of display enlargement on pilot scanning patterns and event detection performance. Nineteen pilots monitored an integrated hazard display for changes in the altitude or heading of traffic aircraft and weather systems. Analyses revealed that event detection accuracy and response time were unaffected by display size, suggesting pilots compensated for display enlargements by strategically widening scanning patterns. While eye movement data revealed that attention was allocated to the peripheral display regions regardless of display size, individuals who were poor at detecting events were less likely to attend to these display areas. The results suggest that the attention allocation patterns of pilots are adaptive and flexible and that such flexibility leads to higher performance in attentional tasks.
