Windsocks can also be traced back as far as 150 A.D, where they were used by the Romans as military banners to differentiate military groups. Nevertheless, it is generally thought the modern windsock was inspired by the wind sails used by naval ships in the nineteenth-century.
Where are windsocks used?
Windsocks are used to tell wind speed and the direction of the wind. Windsocks typically are used at airports to indicate the direction and strength of the wind to pilots and at chemical plants where there is risk of gaseous leakage. They are sometimes located alongside highways at windy locations.
Why is windsock painted black and white?
It helps pilots to make decisions while landing or taking off. However, white and orange stripes on windsocks aren't just decorations! Actually the stripes indicate the purpose windsocks are designed for! Usually they are produced in bright colors to be visible even from a distant area.
