Known as AVOID, it makes it possible for a pilot to see an ash cloud ahead of the aircraft at altitudes between 5,000 and 50,000 feet.
The budget airline, which tested the system on a microlight aircraft over Mount Etna, said the trials were successful and it hopes to install the equipment on its fleet next year.
In April 2010 the eruption of the Eyjafjallajökul volcano in Iceland crippled aviation across Europe, stranding an estimated 10 million passengers across the continent.
Since then the aviation industry has been trying to find a solution to prevent another lockdown of the skies.
One major change has been the decision to allow airlines to make a safety case to fly through low and medium concentrations of ash, subject to the approval of the Civil Aviation Authority.
easyJet believes its technology will enable pilots to adjust their route and avoid the thickest concentrations of ash.
Experts are predicting that Katia will be the next volcano to erupt. They also believe that it will be on a scale far larger than Eyjafjallajökul.
Dr Fred Prata, who invented the system, said that installing the equipment on 100 commercial aircraft would provide enough information to enable European aviation to continue operating.
“Safety is at the heart of the aviation industry which is why we saw the blanket shutdowns in reaction to volcanic ash over the past two years,” added Ian Davies, easyJet’s head of engineering.
“In the absence of proven technology thousands of flights were grounded. This large scale grounding of flights should not happen again, thanks to both satellite and airborne technology which can be used to accurately predict not only the dispersal of ash from volcanic eruption but also crucially the levels of concentration.”
