UK and Irish airspace will shortly have a seamless data link service as a result of UK NATS and the Irish Aviation Authority (IAA) working together with SITA to deliver Controller Pilot Data Link Communication (CPDLC) services to the British and Irish area control centers.
The SITA service and systems support long haul and short haul versions of CPDLC. Long haul aircraft use a Future Air Navigation Systems (FANS) version already implemented over the Atlantic Ocean. Aircraft with FANS systems will now use the SITA network and gateway to communicate with CPDLC systems in the UK and Ireland domestic centers.
Other providers of CPDLC have also hit the headlines recently, including ARINC who now offer a compliance service for airlines.
