This page aims to provide information about how volcanic ash clouds affect aircraft, and how to avoid this hazard.The detrimental effects of volcanic ash clouds need to be understood by the public because ignorance could lead to disaster. If an airplane flies into a volcanic cloud, the silicate particles in the cloud enter the engines and melt, which can lead to engine damage and malfunction and to many other kinds of aircraft damage. Although no deaths have yet resulted, this is quite possible.
