Generally used at airports, airfields, heliports, along motorways or in some dangerous areas.
Drapeaux DEJEAN MARINE can also provide tailor-made or advertising wind-socks.
A wind-sock indicates the force of the wind as each inflated stripe, measures a force of 5 knots (about 9km/h).
The sleeve is horizontal when the wind strength is superior to 25 knots (about 45 km/h).
The wind blows through the largest end of the cone and the sleeve rises in the opposite direction of the wind direction.
