Thomson Airways managing director Chris Browne has called for more accurate ash cloud modelling in the wake of further airspace closures.

Browne said safety was always the number one priority but added: “If the ash clouds are to continue, current modelling needs to become more accurate and there needs to be greater clarity for the industry on operational parameters. 

“It is vital that we understand the tolerance levels for aircraft and engines in particular, but also gain a better knowledge of the predictability of the ash clouds.  

“We are currently leading working parties between the Civil Aviation Authority and other industry partners with the remit of understanding how we can all share knowledge and co-ordinate more accurate forecasting.” 

The airline is urging customers to check and for flight information before travelling to the airport.  

Customers who are overseas will be contacted by their holiday advisors if their return flights to the UK are impacted by the closures.
