Both must understand that volcanic ash is not like sand or dust, and they must know how to recognize inadvertent entry into an ash cloud. A Volcanic Ash Training Video has been developed by the Boeing Company in cooperation with the Air Line Pilots Association and the U.S. Geological Survey. In addition Pilots, Dispatchers, and Air Traffic Controllers must be aware of any potential volcanic activity affecting their area of operation. Should an inadvertent penetration of a volcanic ash cloud be made, flight crews must be aware of potential problems and be prepared to deal with the arising flight conditions. Prompt communication among Volcano Observers, Meteorologists, Air Traffic Controllers, Flight Dispatchers, and Pilots regarding location of drifting ash clouds will maintain a high level of flight safety.
Avoidance requires the coordinated efforts of a broad group of technical specialists.
The goal of these efforts is to avoid an area or airspace that has been contaminated by volcanic ash. Avoidance of Volcanic Ash Clouds is the only procedure that guarantees flight safety 14.
