ACD-57 radio station databank as often as desired within a 24 month period for a specific Air Control Display (based on serial number).
The display of COM station names and the NEAREST station function require a database.
For safety reasons the database must be valid and up-to-date.
The database is stored on a micro SD card. In order to access the database, the card has to be permanently inserted into ACD-57.
