L. W. Spiro’s FAA #1 calibrated windsocks are manufactured to the FAA’s specifications outlined in AC 150/5345-27E. Measuring 18” X 96” our large airport windsock is designed to be fully extended at wind speeds of 15 knots (17 mph) or greater.
Our vinyl coated brilliant orange material is highly durable and fade resistant under extreme weather conditions. All seams are double stitched and three layers of material are sewn on the grommeted collar to ensure strength and lasting durability.
Our replacement windsock also features 12 large 3/8" nickel plated grommets around the opening of windsock and it securely attaches to any standard windsock frame by using the 120 pound tensile strength cable ties that are included in the package. These UV resistent heavy duty cable ties ensure a secure and snug fit that will stand up to any and all extreme weather conditions.
Our large airport windsock frame measures 18” at the throat and is designed to extend into the body of a large windsock a full 24” to hold the windsock open and ready to receive airflow. The frame body is constructed of lightweight aluminum to ensure years of service with a minimum of corrosion due to exposure to the elements.
The large swivel and wishbone construction of this frame ensures sensitivity to winds as slight as 3 mph and the 3/4” pipe thread swivel easily mounts to a standard 3/4” pipe coupling or bell reducer.
