Does Takeoff and Landing Performance use inflight ADS-B or XM weather?

Yes, Takeoff and Landing Performance results will be computed using the airport’s METAR, TAF, or MOS forecast nearest to the estimated takeoff or landing time. If none is available for the selected airport, weather from a nearby airport is used. Weather information will be automatically supplied by the internet, ADS-B, or Sirius XM.
