Aviation Windsock – wind direction indicator

• Windsock material Lightweight Polyester Fabric, 2.4 m long, larger diameter 0.6 m
• Pole Stainless steal
• Base designed as a hinge to be easy to change the socks/cone
• External or internal lighting of the cone with LED projectors
• Comes with an obstruction light on top for marking
• The junction box includes a photocell for turning the lights and obstruction lights automatically during the night
• Fasteners made of Stainless steel

Compliant According to Standards:

• ICAO: Annex 14, Volume I – Aerodrome Design and Operations
• ICAO: Annex 14, Volume II – Heliports

Under international aviation regulations, specifically those set by ICAO (International Civil Aviation Organization) in Annex 14, and by the FAA (Federal Aviation Administration), every aerodrome (airport) and heliport must be equipped with at least one wind direction indicator. Here are the specific regulatory requirements that make it mandatory:

• Primary indicator: A facility must have at least one windsock that is clearly visible from aircraft in flight or on the movement area.
• Night operations: If the airport or heliport is intended for use at night, the regulations explicitly mandate that the wind direction indicator must be illuminated.
• Multiple windsocks: For large commercial airports with long runways or complex layouts, regulations often require multiple windsocks. This ensures pilots have accurate readings of localized wind conditions at different touchdown zones, as wind can vary across a large airfield.
• Heliport specifics: Heliports, especially elevated ones (like hospital rooftops), are subject to complex microclimates and building-induced turbulence. A compliant windsock is legally required to ensure safe approach and departure paths.

Because it is a strict regulatory requirement, choosing a highly durable, ICAO-compliant windsock from a reliable manufacturer like Signalight is not just an upgrade—it is a legal and operational necessity to keep the facility open and certified.

Is the windsock suitable for night and low-visibility operations? 

Yes, we offer illuminated versions equipped with advanced, high-efficiency LED technology. Depending on your specific site requirements, the system can be configured with internal or external lighting to provide pilots with a clear, unambiguous visual reference during night flights or adverse weather. 

How energy-efficient is the illuminated windsock? 

By integrating advanced LED lighting rather than traditional halogen bulbs, our illuminated windsocks consume significantly less energy. This not only lowers the carbon footprint of your facility but also drastically reduces maintenance costs due to the extended lifespan of the LED components. To learn more about how this equipment directly impacts your facility’s operational security and compliance, read our dedicated article on The importance of illuminated windsocks for airfield safety.

Will the fabric cone tangle in shifting winds? 

No, the mechanical design of our airport windsock frame includes a high-quality rotation mechanism. This allows the assembly to pivot smoothly and instantly with the slightest change in wind direction, preventing the fabric from tangling around the mast and ensuring an accurate reading at all times.

What materials are used to ensure durability? 

The windsock assembly is built for long-term performance in severe environments. The frame is constructed from robust, corrosion-resistant materials to withstand heavy rain, salt, and extreme temperatures. The fabric cone is made from durable, UV-resistant material that maintains its high-visibility colors (aviation orange or red and white) without rapid fading.
