• Abstract:
  The expansion of the National Route Program will allow airlines to be more flexible in filing and amending flight plans. This may ; result in a change in the role of the air traffic control specialist from direct control to a position with more monitoring responsibilities. ; This change may result in a reduction of situation awareness, memory and vigilance. This experiment investigated the effect of ; moving a controller from the current active control to a monitoring position. It examined the effect of the change in involvement and ; task load by measuring eye movements, workload, situation awareness, system performance, controller performance ratings, ; organization of information in memory, and responses to questionnaires. Controllers received training on a generic en route airspace, ; the Genera High sector, during four practice simulations of 40 minutes each. They then worked four 30-minute experimental ; scenarios. Results indicated that controllers showed a less structured scanning pattern under high task load and active involvement ; conditions. Measured workload correlated well with traffic volume. Under monitoring conditions, controllers perceived lower ; workload. Controller situation awareness was lower under monitoring conditions and decreased further with an increase in task load. ; Controllers perceived that their situation awareness did not change between active control and passive monitoring. The decrease in ; situation awareness warrants careful examination of the need for training and assistance of controllers for situations where they no ; longer function in the current active control position.
