Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Use this section to quickly compare current wind alignment across available runways at KCPU. This is intended as a planning aid only and should not replace official performance calculations or pilot judgment.
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.
