Aviation chiefs are confident that the UK is much better prepared to deal with a potential ash cloud crisis than it was four years ago.
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 disruption.
