New times have come for aviation communications. Soon it will be basically a data exchange, and voice communication will be used in non-standard and emergency situations. The main emphasis in the development of aeronautical communications is now being made on functioning on a global scale. Globalization makes it possible to use channels more efficiently and provides sharing of opportunities by many users.
There are two main categories of aeronautical communications:
Safety-related modes of communication that must have high integrity and speed: communication between the air traffic management bodies and the aircraft to provide air traffic control, the transfer of flight information, warning messages, and communication for the purposes of aeronautical operational control, implemented by aircraft operators to address issues related to safety, regularity and efficiency of operations;
Non-safety-related modes of communication: aeronautical administrative communication, carried out by aviation personnel and/or aviation organizations for administrative and private matters; aviation communication for passengers.
In addition, for the transmission of surveillance data and data that provide better knowledge of the air situation, direct communication and communication in the broadcasting mode are used.
