Source Type:   Experiment
Synopsis: "An experiment was conducted to explore the effects of automation and task loading on aviation plan monitoring and errors in plan revision. Pilots were asked to select one of two flight paths that traversed through hazardous airspace and to then monitor the safety of the path by seeking and reporting changes in dynamic traffic aircraft and weather systems. Following change detection, pilots were given the opportunity to revise their flight plan as a result of the changes. Attention guidance automation, which was reliable for plan selection, but failed to highlight a critical change that threatened safety after plan selection, was present on half of trials. Automation improved planning accuracy and confidence in high workload conditions. However, in nearly one third of trials, pilots failed to revise the flight plans as a result of a change, and were more likely to do so with imperfect automation in high workload."
