Although volcanic ash is a significant and ongoing threat to aviation, worldwide aviation operations have demonstrated a remarkable safety record. This is partly due to international cooperation in (1) monitoring and warning of significant volcanic activity, (2) improved satellite capability to sense the presence of ash in the atmosphere, (3) development of international standards for managing airspace potentially contaminated by ash, and (4) international cooperation in researching the effects of ash on aviation safety. These most recent advances were driven by the highly impactful eruption of Iceland’s Mount Eyjafjallajokull in 2010. A summary of the threat of ash to aviation and recent international developments will be discussed.


John Fisher

Senior Technical Specialist (STS) for Aircraft Icing

U.S. Federal Aviation Administration (FAA)


Mr. Fisher is an FAA aerospace engineer and senior technical advisor on aircraft icing as well as volcanic ash issues for transport aircraft, general aviation aircraft, rotorcraft, and engines. Mr. Fisher has over 40-years in aviation as an aerospace engineer. He has been the primary regulatory and technical lead for research on new capabilities for ice crystal icing conditions, and improved means of compliance for turbine engine icing regulations. Mr. Fisher has also been the FAA technical advisor on volcanic ash; he has served on the U.S. Delegation team on the International Civil Aviation Organization (ICAO) International Volcanic Ash Airworthiness Task Force (IVATF) as well as several subsequent ICAO WMO committees, which set standards for flight in the vicinity of volcanic ash. He has been involved with aircraft engine related volcanic ash issues since 1997. Mr. Fisher worked as an aerospace engineer for a major engine manufacturer for 12 years before joining the FAA. His 30-year tenure at the FAA has been primarily as an icing specialist, but also as the gas turbine performance and ingestion specialist.
