+x Tim Dawson - 11/21/2019 12:29:31 PMSorry, callsigns are lifted by us straight out of the AIPs used as source material. If you have found an instance where you believe we are adding or interpreting these, please let me know. I will ask my colleague what we do in Switzerland for aerodromes without an AIP entry.I've just checked our DFS digital data and the callsign at EDAZ is explicitly provided to us as INFO not INFORMATION. I will ask them to clarify whether a change to this is planned.
