The Met Office acknowledges the
decision by CAA to change the engine tolerance levels for the safe levels of ash ingestion into aircraft engines.
The Met Office is the north-west European Volcanic Ash Advisory Centre with responsibility for issuing the Volcanic Ash Advisories for this area in line with internationally agreed standards and processes as designated by the aviation regulator and industry.
We will now provide timely advice to NATS about the dispersion of the volcanic ash in line with the new engine tolerance criteria. [more]
