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 PN84. This is intended as a planning aid only and should not replace official performance calculations or pilot judgment.
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 |
|---|---|---|---|---|
| 18 | 1,400 ft | TURF | - | - |
| 36 | 1,400 ft | TURF | - | - |
