when is the ash cloud going to clear?

There's a good chance that the direction of the winds above 25000 feet will change some time this week which would mean that the ash is carried further north.

However, the ash will still be there at different altitudes and there's no reason that the winds won'T change again soon.

The best answer already given here is that it will only disappear when the volcano stops erupting.

the reason a mild airplane can fly fairly close to to an eruption, yet an airliner won't be able to is undemanding. a mild airplane has a piston engine, an airliner a jet turbine (ok, countless jet turbines) you may clear out the quite low volumes of air a small piston engine ingests, and whether a piston engine does take in ash, it is going to placed on out the pistons, yet isn't likely to place ot the fireplace. A gasoline turbine, with the aid of its very nature gulps down huge volumes of air, and that's easily not accessible to clear out this in any respect. Ingest sufficient, and the fireplace is going out. precisely what occurred to a British airlines 747 over the Pacific some years in the past, whilst all 4 engines flames out. As you may think of, this would teach a splash bit an embaressment whilst youi have 4 hundred souls aboard, and a huge boing, perfect suited even though it would desire to be, grew to become into by no skill designed as a glider.

That's a bit like asking 'how long is a piece of string' Even the experts don't know the answer to it so very unlikely that Yahoo Answers can help.

Near about one Month.

It will likely clear but it has the ability to turn the planet into a frozen wasteland.

When everybody stops smoking ;0)

some flights have been suspended till wednesday so i guess it'll soon be mostly cleared and safe to go up

Friday at 15:12GMT.

within days or maybe it will last for years, no way to tell!
