Runway wind check

Estimated head/tailwind and crosswind for each runway end from the current reported wind.

Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
