About the "ADLER EXPRESS" Callsign
When SOCHI AIR EXPRESS pilots communicate with air traffic control, they identify themselves using the radio callsign "ADLER EXPRESS" followed by the flight number spoken in aviation pronunciation. For example, flight 456 would be "ADLER EXPRESS Four Five Six." Radio callsigns are assigned by ICAO and are distinct from the airline's marketing name.
