L-806 & L-806(L) Wind Cone

FAA: L-806 AC 150/5345-27 (Current Edition)
FAA Engineering Brief 67
ETL Certified

Provides visual indication of wind direction and velocity at a location on an airfield. L-806 wind cones are used on smaller airfields, heliports and as supplemental wind indicators near runway touchdown areas on large airfields.

Key Specifications
• Available externally lighted, internally lighted, or unlighted.
• LED or halogen lamps.
• The LED models feature:
- 50,000 to 100,000 hour lamp life, virtually maintenance free.
- Multiple lamp circuits, for improved reliability.
- 80-90% less power consumption than halogen lamps.
- A long-life LED obstruction light.
- Integral power adapter on series-circuit models.
• Incandescent L-810 obstruction light included on halogen-lighted models.
• Size 1 (18" diameter x 8' long) wind sock.
• 1.9 inch diameter steel pole, with frangible coupling at base.
• One piece welded aluminum basket with pre-installed bearings.
• Raincaps protect the bearings from weather.
• May be mounted directly to an L-867 light base, 2 inch NPT baseplate (sold separately).
• The nylon sock is treated for rot, mildew, and water repellency.
• Powder coat painted international orange.

WCH Series Wind Cone
Solar Power Supply

The Solar Power Supply (SPS) is a self-contained photovoltaic power source for the WCH Series L-806 and L-807 wind cones.

• Provides power to ETL-certified wind cones with L-810 obstruction lights (12 VDC LED models).
• Custom designed for the installation site, using 30-year worst case insolation and temperature extremes.
• Operates the wind cone lamp dusk-dawn, controlled by an ETL-certified photocell, to FAA illumination requirements.
• Full wind cone lamp intensity at all times when operating.
• 50 or 135 watt solar panel, with 12-year/90% and 25-year/80% power warranty.
• MPPT charge controller, with custom-programmed temperature compensation.
• On-board indicators for battery, charging and system status.
• 100 to 300 A-H AGM battery, designed for 4000 charge/discharge cycles.
• 10 day nominal battery autonomy.
• Dual-post mount, with frangible couplings, designed to withstand ASCE Exposure C wind loads.
• Temperature range: -45 to +55°C (-49 to +131°F).
• Includes pre-assembled anchor for easy mounting.
• Weather and corrosion resistant construction of powder coated steel and aluminum.
• Solar panel tilts 25-65 degrees in 10 degree steps, factory preset for the installation location.
• Manufactured in the USA.

Ordering Information
The SPS is designed for operation only with WCH Series wind cones. Each SPS is custom configured for the proper solar panel, battery, temperature compensation and height for the installation location. Please contact Flight Light to configure the correct model for your location.

Installation Information
Full solar exposure is critical to the proper operation of the SPS. The solar panel must face due south (in the Northern Hemisphere). Any shading of the solar panel will significantly reduce the energy production. The bottom edge of the solar panel must not be obstructed by snow or vegetation. To prevent shading from the wind sock, the SPS must be installed at least 8 feet from an L-806 wind cone, and at least 12 feet from an L-807 Size 2 wind cone. The SPS is attached to a 4-bolt anchor assembly (included), mounted in a concrete slab. Power is supplied to the wind cone by a cable in liquid-tight conduit through one of the SPS mounting legs.
