2m Daily Messages for SITA

Air transport communications specialist SITA has announced that it is now processing two million messages a day for over 10,000 user aircraft, airline operation centres, air traffic control, and aircraft and engine manufacturers.
Standard cockpit Aircraft Communications Addressing and Reporting System (ACARS) messages are critical for safety and aircraft operations.  They are supported by data link processing centres in Montreal and Singapore and more than 1,200 VHF ground stations.
SITA says that demand for its service has doubled in five years and that new generation aircraft, such as the Airbus A380, still use ACARS systems for flight-critical communications.
SITA Vice President, Aircraft Communication Services, Philip Clinch, said: “ACARS is so embedded in aircraft that it is set to remain the communications backbone for another 15 to 20 years. [It] has been using Immarsat satellites for 20 years and demand is now likely to grow significantly following the Federal Aviation Administration’s approval this month of the use of Iridium satellite communications for mission-critical applications.
“This will allow more aircraft to use satellite ACARS for air traffic control communications enabling denser airspace operations over oceans while maintaining safety.  We are confident that we can continue to meet the growing demand,” he said.
