26 December 2019:SSJ100 aircraft has successfully carried out the test flights and proved the performance capability of ATN system in real conditions in Europe.
SSJ100 aircraft will be additionally equipped with controller-pilot digital private communications system.
The installation of this system is relevant primarily for the operators flying to EU countries.
All the civil passanger aircraft should be equipped with ATN system starting from February, 2020 is a mandatory requirement of the European aviation authorities for flight operations in various European countries above FL285.
Aeronautical Telecommunication Network (ATN) is a system of automatic data exchange between the aircraft and the ground-based air traffic control services. It simplifies the pilot's control of the aircraft, it works through a secure communication channel and provides communication between the air traffic controller and a specific aircraft. The principle of standardised queries used by ATN permits to reduce the time of information exchange between the aircraft and the controllers, reduces the risk of message loss, misunderstanding between the pilot and the ground services in the event of interference.
"ATN system is a novelty in the design of SSJ100. ATN will be installed as one of the main aircraft systems on all newly manufactured SSJ100 aircraft. The aircraft in operation rework will be optional and made on the customer's request under the Service Bulletins," said Andrei Nedosekin, Deputy General Director for Design.
