The term ‘frangible masts’ refers to masts that are engineered to break or deform on impact. The primary purpose in aviation is reducing the risk of structural damage or injury and to prioritise safety for all. In this article, we explore why frangibility is important with anemometer masts across the aviation industry and beyond.
What are anemometer masts?
Anemometer masts are meteorological or wind measurement masts. They have tools attached to measure wind speed and direction at different heights above the ground. They’re used for weather forecasting and research, wind energy development, environmental studies and aviation safety amongst other uses.
Why should anemometer masts be frangible?
Frangible anemometer masts, such as the fibreglass masts offered by Pollite, play a crucial role in various industries. There are a number of benefits to anemometer masts being frangible.
Aviation safety
Frangible anemometer masts are used at airfields and helipads to monitor wind speed and direction. It is essential that pilots, air traffic controllers and others, have access to this information. The data is used to ensure safe aircraft operations during takeoff, landing and taxiing.
The frangibility of the masts reduces the risk of catastrophic damage if an aircraft were to hit a mast.
Personnel safety
Frangible anemometer masts prioritise safety for maintenance personnel who may need to climb or work near the mast.
Environmental impact
The data captured by anemometer masts is essential for meteorological forecasting, climate studies and environmental monitoring. With the reduction of damage to masts and surrounding structures caused by collisions, there is less impact on the environment. More traditional, rigid masts may leave debris which could damage nearby ecosystems. Pieces of fibreglass masts will be smaller and less environmentally harmful. The lifespan of frangible masts is also longer than that of rigid masts, with less maintenance required too.
Regulatory compliance
Frangible anemometer masts situated at airfields are required to comply with aviation safety regulations from the ICAO and FAA. Environmental standards and other industry guidelines should also be complied with.
Why choose Pollite?
Pollite are one of the largest manufacturers of fibreglass masts in Europe. We’ve an international presence that spans across Europe, Asia, USA, the Middle East and Australasia. We work with our clients across every aspect of the design and manufacturing process to create bespoke engineered solutions. We deliver masts that are, globally, the best in class.
The fully fibreglass construction of our standard 10m masts for anemometers allows for easy installation. The masts are coloured with alternative red/white banding in keeping with ICAO regulations. They are lightweight and will not interfere with any sensitive equipment. The top spigot can be supplied in order to fit any brand of sensor. All cabling is routed through the centre of the mast to help avoid corrosion/degradation. An optional winch system enables a one-person maintenance operation.
