Windsocks The airport windsocks are installed at airports, airfields, heliports, and helidecks. For aviation, especially offshore, the windsock can help the pilot determine wind direction in what can often be a turbulent environment. Many of these windsocks are also illuminated for visibility at night.
How Are Windsocks Useful? Windsocks are used to tell wind speed and the direction of the wind speed itself. It is widely used at airports to indicate the direction and strength of the wind and also at chemical plants where there is risk of gaseous leakage.
