I think that past experience when aircraft have encountered such
clouds elsewhere in the world indicates that the answer is yes. A jet
engine must have an awful lot of air going through it, so it wouldn't
need to be very concentrated dust for it to start clogging things up
after a bit. I would imagine that any old piston-engined aircraft
would be pretty much unaffected.

Execpt that the air filters would quickly get clogged

How much dust would block the engine air filters? Even small aircraft have a cabin air
system.

I don't really understand why this is such a big deal though.

Presumably the ash cloud is not 'that' dense otherwise we would have a
blackout.

And will I have to clean the car again once it's all fallen out of the
sky!!??

Looks like France and Spain have shut their airspace too now?

I'm wondering if perhaps you maybe regret pointing us all in that
direction.

Some of the smaller prop planes are having a field day over Dawlish
this evening!
