Runway wind check

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

Current wind is variable at 5 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.
