The current VAAC system (Volcanic Ash Advisory Centre) is based on theoretical models and needs fine-tuning against verified data.  It is producing conservative predictions, resulting in severe and sometimes unnecessary disruption for airlines and their passengers.

IACA argues that an upgraded system is vital for keeping the no-fly zones to the absolute minimum.

Sylviane Lust, Director General, IACA, said:

“Airlines are losing faith in this methodology.  The impact of this theoretical model is so severe and damaging on airlines, and the wider economy, that we need immediate action and an urgent upgrade of the methodology.  This is the top priority for the European Commission.”

“It is time for the European Commission to step up to the plate on behalf of airlines and push through an urgent revision of procedures used to define no-fly zones and to manage airspace.  We cannot continue with the current approach and the longer we do, the longer airlines and passengers will suffer from avoidable disruption.”
