![]() ![]() The ICAO Operational Data Link Panel (OPLINKP) has also been re-established and held its first meeting in October 2010, following a five-year hiatus. The intention is to converge the FANS and ATN worlds to allow as many aircraft as possible to participate in data link services across oceanic and domestic airspace. The definition of ATN services continues under the management of a joint RTCA/EUROCAE working group - SC214/WG78 - that is currently redefining some of the CPDLC and ADS-C messages originally specified in the ICAO SARPS. The FAA is now embarking upon its NextGen system that includes the delivery of Pre-Departure Clearances (PDC) via CPDLC from a number of domestic airports in 2013 and will expand to FANS 1/A CPDLC operations in US domestic airspace from around 2017. The US Federal Aviation Administration (FAA) uses FANS 1/A technology in oceanic airspace in both the Pacific and Atlantic Oceans, and although a short trial of ATN data link was run in the airspace around Miami, Florida, any plans to expand domestic data link operations in the Continental USA was shelved in 2004. ATN Baseline 1 is currently used only within continental Europe. Maastricht uses a gateway that allows communication with both FANS 1/A aircraft and those fitted with ATN data link avionics. FANS-1/A and ATN ImplementationsįANS-1/A technology has been widely implemented in oceanic airspace around the world and is being used in domestic airspace in Australia and Maastricht's Upper Airspace Centre (MUAC).
