What Size Windsock Do I Need?

Posted by on

Windsocks are an invaluable tool which can quickly and efficiently communicate important information about wind strength and speed. In certain situations, the communication of such data can be crucial in maintaining the health and safety of personnel and civilians in the vicinity; for example, on the landing strip of an airport or on the platform of an oil or gas refinery.

The type of windsock needed will vary depending upon its purpose, location, surrounding conditions and any national or international regulations associated with its use. For example, the structural integrity of a taller mast will be compromised if the windsock attached to it is too large or is improperly fitted. Therefore, it’s vital that you seek professional advice before purchasing and installing any windsock on your premises.

In our experience, there are three main categories in which a windsock may be required. These are outlined below, with the recommended size of windsock for each one:

  • Smaller applications, such as farms, highways, firing ranges, zorbing sites, composting sites, private landing strips, unlicensed aerodromes, smaller airports, helicopter landing sites and parachute and paragliding centres

Depending on the purpose and location, there may or may not be specific regulations surrounding the windsock size on these sites. However, we recommend a windsock of between 2ft and 7ft (60cm and 210cm) in length, positioned on a mast of no greater than 10ft (3m) in height.

  • Larger airspaces, such as licensed aerodromes and international airports

According to CAA CAP168 regulations, all larger airports and licensed aerodromes must have at least one windsock of no less than 12ft (360cm) in length installed on their premises, positioned on a mast of no greater than 16ft (4.8m) in height. Additional windsocks of between 7ft (210cm) and 14ft (400cm) may also be installed at such sites.

  • Industrial applications, such as oil and gas rigs and refineries, chemical storage facilities, refrigeration complexes, power stations, water utilities and sewage sites

As with the smaller applications listed above, industrial windsocks generally do not require a specific size to comply with regulations – although a functional windsock must be in place at all times. We recommend a windsock of between 2ft and 7ft (60cm and 210cm) in length, positioned on a mast of no greater than 10ft (3m) in height.
