Datalinkki

Datalinkki is a Finnish term that translates to "data link" in English. It refers to a communication system that enables the transmission of data between two or more points. In a general sense, a datalink can encompass various forms of digital communication, including wired and wireless connections.

In the context of aviation, datalink plays a crucial role in enhancing communication efficiency and safety between aircraft and air traffic control (ATC). Air Traffic Service Unit (ATSU) datalink systems allow pilots and controllers to exchange messages digitally, such as clearances, flight plan updates, and weather information. This complements traditional voice communication by reducing radio congestion and potential misunderstandings.

One prominent example of an aviation datalink system is the Aircraft Communications Addressing and Reporting System (ACARS). ACARS enables automatic transmission of flight information, operational messages, and technical data between aircraft and ground stations. Another important datalink application is Controller-Pilot Data Link Communications (CPDLC), which allows for text-based communication for routine clearances and requests. The implementation of datalink technologies aims to improve situational awareness, reduce controller workload, and ultimately enhance the overall safety and efficiency of air traffic management. Beyond aviation, the concept of datalink is fundamental to many other telecommunications and computer networking applications.
