Controller Pilot Data Link Communications (CPDLC) |
A method by which Air Traffic Controllers can communicate with pilots over a datalink system, increasing the effective capacity of the communications channel. Datalink permits the exchange of text-based messages between Air Traffic Control (ATC) ground systems and the aircraft. It is intended to supplement traditional voice over VHF and HF radio frequencies and free up voice radio channels.
The ICAO standard for Controller-Pilot Data Link Communication (CPDLC) using the Aeronautical Telecommunications Network (ATN) is preferred for continental airspace and is currently being deployed in the core European Airspace by the Eurocontrol Agency under the Link2000+ Programme. Mandatory carriage of the ICAO compliant system is not the subject of an Implementing Rule, for aircraft flying above FL280, issued by the European Commission. This rule accommodates the use of FANS-1/A by long haul aircraft. All other airspace users must be ICAO compliant.
