VFR frequencies and airspace boundaries especially within Class D airspaces don’t seem to match the real-world data in Italy, many airspcaes shows “No communications available for this sector” instead are existent.
you can verify these discrepancies easily through OpenFlightMaps at this link: LI - Italy | open flightmaps | aeronautical data under a public license or i can provide more data from charts
I checked the Taxi Tuner tool, but I noticed it doesn’t have a feature to rectify or edit airspaces/sectors directly.
I’m more than happy to provide further info to help the team fix these sectors.
