Interesting looking at flightradar24.com - Not a single civil movement
over the UK and a lot of western Europe . . . .

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.

Why then is it so important that aircraft avoid what seems to be a
little bit of fine dust?

I understand that the plane can suffer engine failures etc if it goes
through dense cloud of volcanic ash but is that likely to happen at such
limited concentrations?

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

Are you going to be the one to volunteer to take a large passenger jet
to Oslo at up to 30000ft?

No, thought not.

No, of course not because I've been advised not to.

What I asked was why not and from your sarcastic reply "Cuddles", I
guess you don't have the answer either!

However, a bit of googling has, as usual, found the answer.

For those interested, here is the reason why the planes have been
grounded . . .

That covers jet planes, yes. But why have all propeller-driven aircraft
been grounded as well?

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.

Most prop aircraft are jets, turboprops, gas turbines.

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.

People are trying to tell me that gliders are also grounded.
That is total nonsense. For heaven's sake, they don't *have*
engines, and they are unlikely to get up to 55,000 feet. The UK
height record is only 38,000 feet.
