The use of datalink contributes to the safety and efficiency of air navigation during all flight phases. SITA’s ATS AIRCOM Future Air Navigation System (FANS) enables air navigation service providers (ANSPs) that provide FANS-1/A service to communicate with participating aircraft. FANS-1/A service includes air traffic services facilities notification (AFN), controller-pilot datalink communications (CPDLC) and automatic dependent surveillance contract (ADS-C).

SITA has been involved in the development of FANS from the beginning. In 1994, SITA started work with Boeing, Airservices Australia and the US Federal Aviation Association (FAA) to achieve Part 25 Certification of the FANS-1 package. Since then, SITA has worked closely with all parties to ensure the interoperability of all system elements.
