Measuring Benefits of Controller-Pilot Data-Link Communication (CPDLC) System in an Airport Area Using a Microscopic Simulation Model

The Federal Aviation Administration (FAA) plans to implement a controller-pilot data-link communication (CPDLC) system in the near future. Unlike conventional voice-channel communication systems, the CPDLC system allows pilot and controllers to exchange messages via specially designated data links thus reducing voice communication congestion. Under the proposed CPDLC system, pilots can see an air traffic controller message in text format on a Multifunction Display (MFD). Similarly, pilots can send a message to controllers using pre-coded messages via the MFD. By reducing communication times, the CPDLC system is expected to reduce flight delays at congested airports and in the airspace. The system is also expected to decrease operational and communication errors that could lead to fatalities. The CPDLC system can be implemented in multiple domains in the air traffic control system including airport area, Terminal Radar Approach Control (TRACON) areas, Air Route Traffic Control Centers (ARTCC). Previous studies have focused on the evaluation of CPDLC benefits in either the TRACON or ARTCC domains. In this paper, we assess the benefit of implementing CPDLC system in an airport area using a microscopic airport simulation model.
