Abstract:We emulated the new color standard, FAA HF-STD-010A, Baseline Requirements for Color Use in Air Traffic Control Displays, on a Terminal Radar Approach Control (TRACON) Primary Control Monitor (PCM). We then sought to identify human factors issues that may affect the broad implementation of the new color standard in existing and future air traffic control displays and identify areas where further research is required. Method: We conducted an operational usability assessment of the new color standard using a high-fidelity simulation platform, including dynamic air traffic scenarios. Six Air Traffic Control Specialists (ATCS) with normal color vision participated in three separate groups of two. The ATCS managed simulated traffic at two adjacent TRACON sectors using both the legacy and the new color standard. Results: We assessed airspace activity, communications, and subjective workload ratings, and found no significant differences between conditions or trials. The participants adjusted display brightness settings about twice as often with the new color standard but made these adjustments primarily for testing purposes rather than to improve legibility of a particular display element. Overall, the participants rated the legibility of objects on the PCM as moderate to high for both color standards.
