Volcanic ash and aviation: Recommendations to improve preparedness for extreme events

The study stresses the need for further funding of research on the impact of ash on jet engines since lack of knowledge in this area limits the benefits of advances in ash forecasting. The application of the Safety Risk Assessment approach needs to be coordinated across nations. Strengthening society's resilience as a whole to such events, calls for a comprehensive long-term contingency plan, including alternative transportation if aircrafts are grounded.
