Weather in X-Plane 12: LiveTraffic can set X-Plane's weather based on RealTraffic weather data and/or METARs, either live, historically (from RealTraffic), or by pasting any METAR into the settings. See documentation for details and take note of the limitations.
RealTraffic:
Parked aircraft loaded from RealTraffic, populating parking spots in major airports, based on positions, in which RealTraffic saw aircraft stop then disappear from tracking in the past 24h.
Faster startup, planes will appear within seconds, as RealTraffic provides startup data to fill the buffer.
OpenSky is again enabled by default in new installations.
If you want to use OpenSky in an existing installation just activate it in the channel's settings.
Increased number of allowed aircraft to 300, room needed to allow for parked aircraft at large airports. Set in Settings > Advanced.
