A study was conducted to investigate the way in which controllers deploy their attention in processing information in en route air traffic control scenarios. Actual air traffic control scenarios in which operational errors occurred were re-created using SATORI and displayed to twenty active air traffic control specialists. SAGAT was used to measure the subjects' ongoing understanding of the scenarios along pertinent situation awareness requirements. The data revealed an interesting pattern of attention distribution in processing the displays that can be linked to prior findings regarding operational errors in air traffic control.
