The Impact of Trajectory Prediction Uncertainty on Air Traffic Controller Performance and Acceptability  (2013)
Abstract Header
A Human-In-The-Loop air traffic control simulation investigated the impact of uncertainties in trajectory predictions on NextGen Trajectory-Based Operations concepts, seeking to understand when the automation would become unacceptable to controllers or when performance targets could no longer be met. Retired air traffic controllers staffed two en route transition sectors, delivering arrival traffic to the northwest corner-post of Atlanta approach control under time-based metering operations. Using trajectory-based decision- support tools, the participants worked the traffic under varying levels of wind forecast error and aircraft performance model error, impacting the ground automation's ability to make accurate predictions. Results suggest that the controllers were able to maintain high levels of performance, despite even the highest levels of trajectory prediction errors.
