This is the big question mark? are the limits set to ensure that jet engines run their full expected time ( An airline economic decision) or are they set at a level to ensure that an aircraft is not brought down on a particular flight?
The present limits are still a tiny fraction of the Ash density at the Volcanic cloud source and so low as to not be visible to the naked eye in mist or cloud form.
The Metoffice do a fantastic job limited by the data they have and the tools available to them as well as the mandate that is given to them.
The Friday predictions of dense ash over most of the uk had the media blazing those pictures with headlines of holidays to be ruined for millions of passengers!!!
As those computer predictions have been proved to be so inacurate then surely they should be backed up by round the clock testing of those airmasses to confirm the predictions?
No wonder the Airlines tear their hair out when the predictions change overnight.You cannot run any business with such uncertainty and its the Airlines and our industry who pay not the burocrats,regulators or backwatchers.
