Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is variable at 3 kt: light and variable wind like this is generally not a factor for runway selection, and with no steady direction there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.
| Runway | Length | Surface | Head / Tail | Crosswind |
|---|---|---|---|---|
