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.
| Runway | Length | Surface | Head / Tail | Crosswind |
|---|---|---|---|---|
| 11 | 3,675 ft | TURF-F | - | - |
| 29 | 3,675 ft | TURF-F | - | - |
