UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law. These pages are undergoing reviews and updates.

Volcanic ash can adversely affect aircraft in a number of ways. Jet aircraft engines in particular are susceptible to damage from volcanic ash. That's why there are comprehensive safety arrangements in place.

As a result of the work that has been undertaken since the 2010 ash crisis and arrangements that have been put in place since, we are confident that high levels of public safety can be maintained, while minimising any disruption.

These improvements include:

  • A new system of regulating the way aviation deals with ash that allows more airspace to be used safely and provides airlines more input into the process.
  • Improvements in the observing and forecasting of where ash is and its density - including a new radar in Iceland to detect ash in the atmosphere.
  • The establishment of two working groups including airlines and scientists to act as advisors on ash forecasting and how best to use the output from the Met Office modelling system.

The CAA can't stop volcanic activity, but we are continuing to work with the aviation industry to develop further technical solutions that will increase flying when we are sure it is safe to do so and are endeavouring to ensure interruption is kept to a minimum.
