CPDLC (Controller Pilot Data Link Communication) is an air/ground data link that enables the exchange of text messages between controllers and pilots. CPDLC complements traditional voice communications, providing pilots and controllers with an additional communications medium. In this way CPDLC improves the safety and efficiency of air traffic management by introducing data link services for the single European sky. The European mandate for this modification is February 2020.

The main part of modification is the one-box Spectralux CPDLC unit that will be integrated in the pedestal. Communication is by a dedicated VHF antenna that forms part of the modification designed by Fokker Services under its Part 21 Design Approval. If required a GPS antenna and receiver can be included in the modification as well as other options.

Fokker delivers the complete modification package comprising the STC, manual supplement and modification kits.
