*ATIS (opcija)- Automatic Terminal Information Service, ili ATIS, je neprekidno emitiranje informacija kod područja zauzetih terminala (npr. zračna luka). ATIS emitira vrijeme,aktivne piste, slobodni pristupi. Piloti obično poslušaju ATIS informacije prije kontaktiranja kontrolnog tornja kako bi olakšali posao kontroloru i ostavili slobodnu frekvenciju.
