New Volcanic Ash warning.
 

Watch out ADL.

Volcanic Ash Graphics 5

:D

This could go on and on. Mother nature does what it wants. She's not concerned.

Where's Dick Smith to tell us all that everything is safe and it's just the airlines being "ultra-conservative"?

Qantas, Tiger and Jetstar have ceased all flying to/from Adl till tomorrow mid morning.

Forget the Dick....GT is the new 'go to man'. He knows everything about aircraft, engineering, weather, volcano's, airline finances, aviation investments, Mrs Wirthless make-up and hair stylist etc etc...........

are melb-LA flights affected by this??

A return to PrPRuNe
 

I remember (back in the 1990's & early 2000's) when pprune was a font of knowledge.

It has since turned in a simpering cauldron of narrow and nasty industrial tribal warfare.

Have any of the 'professional pilots' on this forum seen any evidence of volcanic clouds worth mentioning?

With the current hysterical over-reaction to the ash-plume eminating from Chile - it would be ideal to get feedback from qualified and experienced eye-witnesses. Why the silence?

Dic#head, try reading this;
British Airways Flight 9 - Wikipedia, the free encyclopedia

BA flew into the Ash cloud VERY CLOSE to it's ejection point and the amount and size of the ash was significant.

NOT the same as we are seeing above us ( or rather NOT seeing )

If you guys and gals could get hold of a Boeing Maintenance Manual, go to ATA Chapter 5.....

Look for 'Conditional Inspections'.

Then read "Flying through Volcanic Ash".

You probably wouldn't be asking "Why?":ugh::ugh::ugh:

Hi Redpanda,

I agree - one should never fly through significant volcanic ash.

I do not believe that we have significant volcanic ash over Australia at present.

The airline operating manuals also state that flight should not be conducted through thunderstorms and micro-burst and so forth. Which is not interpreted by the general aviation community as as reason to cancel all flights. We are (I thought...) smarter than that. We understand that the danger in these phenomenon is specific and identifiable and definable.

Where is this supposed 'boogey-man' of a volcanic ash cloud? It would be different if it was in Indonesia or New Zealand. But, for goodness sake - this ash cloud (for want of a better word) has come from South America. And, it hasn't even come the shortest route - it's come via South Africa.

It is so dispersed it is unidentifiable.

Hey HIALS

A one minute flight through volcanic ash can halve the value of an aircraft fuselage without even looking at any of the various engine considerations.

You may have spent too long in a third world environment (pardon the pun)

I agree that a one minute flight through an erupting volcanic plume will destroy an aircraft.

My point is being lost.

This is not a proximate volcanic plume. It is an enormously dispersed cloud.

The Icelandic volcano that disrupted Europe was a 4 hour flight away from AMS/FRA/CPH/LHR etc. (I know because I have flown from continental Europe to Iceland in a 747 many times.) That would be the equivalent of having Chile, in this example, in the same location as Perth......

This ash cloud (for want of a better word) has come more than half way round the world..... It didn't even come the short route (i.e. South America to Australia/New Zealand) it came the long way round. This ash cloud has travelled from South America, via the South Atlantic to South Africa. Then onwards across the Indian Ocean to Australia. It is preposterous to think it still has the same density of pumice material as the other volcanoes that have disrupted air travel.

All the aircraft operating manuals being quoted are irrelevant. I'm saying - the Emperor Has No Clothes. I suspect there is no ash cloud.

NASA's Unexpected Volcanic Ash Encounter FlightFor those keen to see the airlines HTFU on this I think the above story will go some way to explaining why it's simply not worth the risk.

Have a look at the IR image animation at the bottom of this page & see how dispersed it isn't:

Perth 115Eish

With 175 degrees of longitude separating them, it doesn't look like there is much of a short cut anyway.

Bon soir le pingouin,

Perhaps I am seriously deluded - but that IR Sat Pic showed the 'red bit' traversing to the South of Australia (even the south of Tasmania).

Furthermore, it did not quantify the density of the cloud.

dudduddud - it cannot and did not travel over the south pole. The plume is travelling around the world in the roaring 40's wind.

Have you ever flown over the pole? I have flown polar routes (up to 89 degrees North) for years. The idea of equating Great Circle Tracks to the geosphere is really ignorant.

HIALS,
I agree with you lets face it, it is a world of risk analysts now, and they call the shots, 40 years ago they wouldnt have known and only aircraft flying into the plume nearby ever had any problems. Lets face it all the radiation released from tests and reactor problems never got mapped so we are OK right?? We live in a mad world!:ugh:

HIALS, the point is you claim the ash is "dispersed and unidentifiable", while the images clearly show it is very much the opposite. The tail of it clearly washes over Tasmania & possibly into the Bight.

You believe what you want but the satellite images are showing detectable quantities of ash.
