Simulation-Based Study to Quantify Data-Communication Benefits in Congested Airport
Terminal Area (2009)

The scope of this study is to evaluate the impact of air traffic controller-to-pilot communication standard known as Controller Pilot Data-Link Communications (CPDLC) on the future air traffic operations. The impact was evaluated from the double viewpoint of airport delays and air traffic controllers’ workload. RAMS simulation software is used to perform all the runs and from its output data the values of terminal area delays and controllers workload are extrapolated. Two levels of Data-Communication implementation are tested and compared to a baseline scenario with no implementation. The New York Metroplex terminal area is used as the case study. The results of the study, based on some previous man-in-the-loop simulations performed by the Federal Aviation Agency showed that modest benefits could be obtained with the complete implementation of such technologies in the workload experienced by air traffic controllers. Moreover some small but not negligible benefits were obtained in the total delays accrued by each airport studied.
