A method for displaying data in an avionics communications system is disclosed. The method generates an ARINC 661 definition file and a user database from one or more user-defined inputs for a communications management function of an aircraft. To convey information relating the one or more user-defined inputs with at least one display of the aircraft, the method links one or more display attributes of the user database with the ARINC 661 definition file. Based on user interactions with the at least one display, the method updates display data of the at least one display using the contents of the ARINC 661 definition file and the user database.
