1 Airline Meteorologist Perspective on Volcanic Ash UPS/A4A 30 OCT 2012

2 First Hours Critical to Aviation Aircraft radar does not detect volcanic ash. Rapid dissemination of new eruption the first 5-10 minutes to enroute aircraft, airlines, and ATC is critical. NWSChat Live could be used for collaboration & information sharing.

3 Flight Planning & Route Selection Authority Once Hazard has been identified: –Individual operators are responsible for route to be flown, not ATC. –ATC or Gov’ts should not close airspace. Airline experience shows VA 36-48 hours removed from a source rarely if ever are a significant hazard to aircraft.

4 More Research/Observations of Ash Concentrations needed Int’l Volcanic Ash Task Force (IVATF) unfinished work. Formed after Spring 2010 Icelandic Eruption shut down European Air Space. IVATF sunsetted in Summer 2012 Progress made, but more is needed. For example: –What ash concentrations/particle size distributions are aircraft hazards? –Monitoring of ash concentrations needed (remote sensing or UAV sampling). –Are some volcano types more likely to produce larger VA particle sizes that cause aircraft damage?

5 VAAC Standardization VAAC models, assumptions and procedures are not standardized. Some VAACs can’t use advanced satellite imagery or don’t have access to the right tools. Some VAACs rarely have VA events. VAAC consolidation or realignment would help. Products from some VAAC’s are non-standard & not ICAO specified. (e.g. Ash Concentration Charts in Europe)

6 VAAC/SIGMET/TAF Coordination Once a SIGMET has been issued it is primary VA forecast product for operators. VAAC advisory is primary source for planning beyond SIGMET timeframe (4-6 hours). SIGMET for VA aloft should not lead to an automatic use of VA in the TAF. VA should only show up on METAR/TAF when VA is reaching the ground at the airport.

7 Quito, Ecuador Nov 3-10, 2002 Ash Fall Volcanic Ash at an airport is very costly. 1 UPS Aircraft stranded for 6 days. Economic cost to UPS Airline $400,000
