First 8 Hours of Volcanic Eruptions: A Northwest Airlines Example & Recommendations of Revised Flow of Ash Information for Aviation

This paper describes the conceptual framework and existing protocol for improving or streamlining the standardization of information and data exchange between Volcano Observatories, Volcanic Ash Advisory Centers and Meteorological Watch Offices. These organizations all deal with disseminating hazard and advisory information to the aviation community regarding airborne volcanic ash and volcanic eruptions. There are currently 5 steps involved in notifying aircraft pilots and dispatchers about volcanic eruptions and volcanic ash. Time is crucial in getting the hazard warnings out, and interorganizational relations and coordination need to be tight and trusting. The paper bases its information on a Northwest Airlines experience and also on the deficiencies noted in the standardization and information dissemination system.
