Eurocontrol is warning helicopter operators, especially offshore oil operators, of a potential threat posed by “skysails,” giant kites that help propel some large ships such as oil tankers and container carriers. On September 15 a helicopter was descending over the southern North Sea to a nearby oil or gas platform when the crew saw such a skysail. It was flying ahead of a vessel, at around 1,000 feet, just below the clouds.
Aviation and the environment often appear to be in conflict, sometimes in unpredictable ways. One such has led BAE Systems into a collaboration with the UK government and the British Wind Energy Association (BWEA) on a research project that aims to eliminate the interference that the rotating blades on wind turbine installations can cause to air traffic control radars.
