      It's not an error. Most WF-aircraft can only be viewed in areas with MLAT coverage. It's all explained in the FAQ.

      • Antonov An-124 and An-225
      • ATR 42, 72 (except most new deliveries of ATR 72-600)
      • Boeing 707, 717, 727, 737-200, 747-100, 747-200, 747SP
      • BAe Jetstream 31 and 32
      • All Bombardier CRJ models (except most new deliveries of CRJ-900)
      • All Bombardier Dash models
      • All CASA models
      • All Dornier models

        Same problem with me.
        The problem occur in the last 2 month.
        I think it is because my network have problem with UDP connection.
        The feeder software maybe can not detect intermittent UDP connection,
        so the status still OK but actually no data sent to fr24 server.

          Everything looks normal in feeder status,but not visible in FR24,see attatchment(0 FT ,plane is landet,but altitude is registrated when airborne)As soon as it come under coverage og other feeders it will appear in fr24 ,data source listed as ads-b
