The Visibility of Airborne Volcanic Ash from the Flight Deck of an Aircraft – The Effect of Clouds in the Field of View
In April 2010, the volcanic ash cloud from the Eyjafjalla volcano in Iceland strongly impacted aviation in Europe. Several other incidents in the past have shown that volcanic ash can have severe consequences on aviation. One operational necessity is, therefore, to determine whether a pilot has the...

In April 2010, the volcanic ash cloud from the Eyjafjalla volcano in Iceland strongly impacted aviation in Europe.
