To help prevent air traffic chaos following a volcanic eruption, a Norway-based company has invented an ash detector that attaches itself to a plane, so pilots receive a warning before flying into dangerous particles.
The infrared camera developed by Nicarnica Aviation in Kjeller is now undergoing ground-based testing at Iceland's Holuhraun eruption, where it caught toxic volcano tornados spinning in sulfurous gas spewing from the fiery lava, Live Science reported.
The sensors have also received air trials from Airbus and EasyJet.
Following the 2010 eruption of the EyjafjallajAkull volcano in Iceland, approximately 100,000 flights had to be cancelled and 10 million passengers were stranded.
Ash particles are jagged and sharp. The fine, glassy rock could damage and abrade engines, windows and other structures on aircraft flying at all altitudes.
