• 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.
