The International Air Transport Association (IATA) has once again hit out at European authorities for their handling of the volcanic ash crisis, and called for the urgent development of procedures to avoid further travel chaos. The call came in the wake of this week’s latest round of airspace closures, which led to as many as 1,000 flight cancellations on Monday.”This problem is not going away any time soon. The current European-wide system to decide on airspace closures is not working,” said Giovanni Bisignani, IATA’s Director General and CEO. “We are still basically relying on one-dimensional information to make decisions on a four-dimensional problem. The result is the unnecessary closure of airspace. Safety is always our number one priority. But we must make decisions based on facts, not on uncorroborated theoretical models.” Bisignani called for three key points of action; more robust data collection and analysis, a change in the decision making process, and greater urgency in addressing the issues. He slammed the lack of a coordinated response, saying; “We have lost confidence in the ability of Europe’s governments to make effective and consistent decisions”. Bisignani will now travel to Montreal this week for urgent meetings with the International Civil Aviation Organization (ICAO) regarding the issue.
