Airport Windsocks

For a private strip, the 18" x 96" (8 foot) sock is the standard airport size and is easy to read from the pattern. Larger fields and busy strips use the 36" x 144" (12 foot) sock, which pilots can spot from farther out. Smaller sizes such as 10" x 36" and 13" x 56" suit hangars, homes, boats and gifts.

The FAA's two standard airport windsock sizes are 18" x 8 feet (the L-806 size) and 36" x 12 feet (the L-807 size). Our 18" x 96" and 36" x 144" socks match those dimensions. If your field is a public-use airport that needs a certified L-806 or L-807 assembly, check your airport's requirements before ordering.

Buy a kit if you are putting up a new windsock: you get the sock and a stainless frame sized to match. If your frame is in good shape and the sock is faded or torn, a replacement sock is all you need. Match the sock's throat diameter (the first number in the size) to your frame.

The stainless frame threads onto a standard 3/4" NPT pipe, which you can buy at any hardware store. The pole is not included. The frame ships flat-packed and bolts together with the included stainless hardware, then the sock ties on through its brass grommets. Mount it clear of hangars and trees so buildings don't bend the wind it shows.

The sock points downwind, so the wind is coming from the open throat end. How far it fills shows the speed: a standard airport windsock stands fully straight at about 15 knots. On a five-band striped sock, each band that fills is roughly 3 knots. A sock that swings back and forth means gusty or variable wind.

Both are high visibility. Solid orange stands out best against green fields and trees. Orange and white bands are easier to spot against snow or a bright sky, and the stripes make it quicker to judge wind speed at a glance.

No. The frame and every nut, bolt and washer are 304 stainless steel, and the swivel uses sealed, pre-lubricated ball bearings, so it holds up at coastal fields and in wet climates.
