Abstract:The expected increase in air traffic makes it essential to investigate how to develop tools to assist controllers best without sacrificing safety, efficiency, or workload. The Future En Route Workstation Study (FEWS I) concept takes an integrated approach to controller workstation development that applies best human factors principles to the design of the computer-human interface to promote more efficient and effective controller interaction. The current simulation assessed controller performance and workload using the Display System Replacement (DSR), the En Route Automation Modernization (ERAM), and the modified FEWS interface(FEWS II). We measured controller eye movements, situation awareness, ratings about system features and functions, workload, performance, and measures of aircraft efficiency at air traffic levels corresponding to levels anticipated for 2015 and beyond. The FEWS II configuration resulted in fewer data entries than DSR or ERAM, although it did not result in a reduction in workload. Controllers had a significantly lower number of controller deviations when using the FEWS II configuration with a two-person sector and Data Communications available. We showed a reduction in controller workload when Data Communications was available in a two-person sector. Regression analyses showed that at the same workload level, controllers could handle more aircraft when they worked as a team and Data Communications was available.
