I think EasyJet needs a pat on the back for funding this research. Only by investing in projects like this will we be able to mitigate against the effects of volcanic ash.
Can it also distinguish melting points of the ash particles? Don't know
Can it scan like a weather radar? Yes
Does it display color images in the cockpit like a weather radar? Yes
When do they anticipate that it will be certified for flight? Don't know
Who is paying for the development? EasyJet
I hope they get a return on their investment.
