Controller-Pilot Data Link Communication – (TAXI-CPDLC)

Abstract

Increasing traffic rates in aviation cause bottlenecks in safety and efficiency, particularly on the ground at major airports. Voice communication radio channels are often overloaded and pilots are less supported to find their way and to avoid other traffic. Controller-Pilot Data Link Communication during taxi (TAXI-CPDLC) is one promising service to bring benefits in terms of unload the radio channel by taking over ‘routine communication’ and to enable the transfer and representation of the cleared taxi route in the cockpit. This paper details the concept and results of a new TAXI-CPDLC service and provides recommendations for its future use and implementation.
