Guernsey Airport is taking action to improve runway safety, after investing in new green frangible approach masts from UK manufacturer Pollite Ltd, as part of a wider £80m (US$121.8m) runway redevelopment.
The masts will house new airfield ground lighting, which has been purchased as part of Guernsey’s ‘Airport 2040’ project. The deal marks the launch of Pollite’s mid-hinged pole, specially designed with two hinges attached either side of the mast to enable it to be scaled down for easy maintenance.
This is the first time Pollite has been asked to design and manufacture frangible approach masts that do not follow the global ‘aviation yellow’ colour pattern. Instead, Guernsey’s masts are covered with a green gel coat, in order to blend in with the natural environment.
Airport Director Colin le Ray explained: “The typical aviation yellow masts would have been a complete contrast to the areas surrounding the runway. For this reason, the approach masts needed to be green as well as conforming to a defined, appropriate RAL standard colour.”
Guernsey Airport’s uneven topography meant that extra attention was given to ensure that all lights would be raised to the correct level upon installation. The masts were carefully designed and erected to minimise their environmental impact. The design stage involved extensive consultation with the consultant RPS Gregory and the electrical contractor Environ.
Airport 2040 includes re-profiling and resurfacing the runway and taxiways, an extension of the Runway End Safety Areas and reconstruction of the concrete apron.
