Time to bring back propeller driven planes ...

The mash have it spot on again.

As the Icelandic volcano attack entered its fifth day...

Like it.

Ryanair has cancelled all of its flights until Wednesday, though aviation experts stressed this is probably just an elaborate tax dodge.

Professor Henry Brubaker, of the Institute for Studies, said: "According to my computer, it would take ages to get to Australia, but, by the same token, it would also take an awfully long time for Australians to get here. Which would, of course, be excellent."

Anyway getting back to propeller aircraft. You could probably guess at how much filtering you'd need in place from a given concentration of dust in the air. E.g. if air were 1 part in 1000 ash, fuel on board 50 tonnes, fuel to air mixture 20 to 1, that's 20*50,000 Kg air used = 1,000,000 kg air per that flight. Dividing by 1000 = 1000 kg dust in the filters. Those are just made up numbers though. Presumably actual dust concentrations would be less. For a turbo or jet engine the dust figures would be staggering.

Back in my 100metres days I'm sure I gained an unfair advantage from start line flatulence.

The gas knocked out the other competitors.

not all propeller planes would work in the cloud of volcanic ash, only piston prop planes because these do not suck in air like the turbo prop planes. Turo prop planes work on exactly the same prinliciple as a jet engine except that the force is used to spin propeller instaed of thrust

Thanks for that.

[Swati]

Thanks for that.

Welcome sir

[sasguru]

Welcome sir

Are you making much propellerings for very much cheapings?

[Drewster]

.....it's a toss between MF and Sasguru....

Oh FFS!!! Did you have to!!!!
I'm not going to sleep tonight.... I'll never get that image out of my head!!
