March Solution VAAC London ash concentration data - NO FLY ZONE - Contaminated Zone - Ash Free Zone EUROCONTROL charts: to assist states in determining NO FLY ZONE buffer of 60NM States to decide on NO FLY ZONE 9
EHNANCED ROLE FOR EUROCONTROL/CFMU Early warning issue information on volcanic ash activity On request of national ATC providers : CFMU applies measures Facilitate information exchange e.g. organise teleconferences, help desk Publish charts to assist states in deciding on NO FLY ZONE NOP used as central data repository Collect reports on Volcanic Ash (initially for FABEC then ECAC wide) through EUROCONTROL Voluntary ATM Incident Reporting (EVAIR) mechanism 10

Instead of Conclusions Issues Volcanic ash vs. volcanic dust Accurate simulations of volcanic ash encounters for various types of aircraft and engines Similarity between volcanic ash/dust and sand atmospheric pollutant Volcanic ash longevity in the atmosphere Operators risks vs. ATM risks Impact of volcanic ash/dust on the human body Key Questions to be Answered What is the influence of the particle sizes on the aircraft parts exposed? Increased wear or safety hazard? Where does the safety hazard begin? There is much flying experience in sand contaminated atmosphere; is it worth using it for volcanic ash? Is it fair to demand total avoidance of the volcanic ash, since it floats up in the atmosphere for years? If operators decide they could fly through a contaminated area, is the ATM system able to cope with the increased emergency probability? Do aircraft occupants risk anything by breathing dustcontaminated air? Risk functions Reporting system optimization for relevance Does the risk function depend on concentration threshold, or time of exposure, or both in certain proportions? Does the risk depend on the particles dimension distribution? How should pilot reports and objective measurements be consistently used in an information system used by decision makers? We need appropriate and commensurate RISK MANAGEMENT!!! 18
