Frangible Windsock Masts: Airfield

All Pollite airfield windsock masts are designed to comply with:

• CAP 168
• ICAO Annex 14 Vol 1 Aerodrome Design and Operation Manual
• FAA AC 150/5345-27D L806/807

Windsock/Windsleeve

All windsocks are manufactured in house to meet ICAO and CAA requirements for size, material and colour. Client specific colours can be provided and all colours used are designed to give maximum contrast with their background.

Recommended Windsock Size

Minimum length 3600mm, Minimum diameter 900mm

Colour Recommendations for Wind Socks

Wind direction indicators need to be visible and understandable from a height of up to 300m.

• ICAO Single Colour recommendations: Orange or White
• ICAO Two Colour recommendations: Orange/White, Black/White or Red/White

The windsock is attached to the mast by means of a rigid mounting frame (similar in shape to a drum) that can freely rotate around the mast giving a clear indication of wind direction particularly in lighter wind conditions.

Windsock Mast

All windsock masts are manufactured from frangible glassfibre with a UV resistant gel coat finish, coloured red and white as standard. The windsock is supported on a stainless steel framework, designed to rotate 360 degree around the mast and to hold the throat of the windsock fully open in all wind conditions. Rotation is ensured by a series of enclosed lubricated stainless steel bearings for the internally lit sock or self lubricating bearings for the externally lit mast.

All Pollite windsock masts come complete with a unique hinged foot which allows for easier raising and lowering of the mast for servicing the lighting or windsock.

With Internally Lit Sock

ICAO// FAA L807 Style I-B// L806 Style I-B

For aerodromes that are used at night our standard lighting system for windsock masts has been engineered to provide the correct level of illumination as recommended by ICAO and FAA without causing unwanted glare.

As per FAA requirements each internal lighting mechanism comes complete with two light fittings ensuring that the failure of one light will not render the mast ineffective and the average luminance of the sock has been measured to ensure compliance with the photometric requirements of FAA AC 150/5345-27D.

An Obstruction Light is fitted as standard on all masts and available with our 50,000 hr LED light fitting.

A photocell and double switch is provided as standard to ensure best function.

With Externally Lit Sock

CAP 168//ICAO// FAA L807 Style I-A // L806 Style I-A

Lighting on the externally lit sock is achieved from 4 No. 70 Watt SON Floodlights secured to a cross arm arrangement at the top of the mast. The illumination provided complies with the FAA and CAP 168 photometric requirements.

An Obstruction Light is fitted as standard on all masts and available with our 50,000 hr LED light fitting.

A photocell and double switch is provided as standard to ensure best function
