Is it coincidence that National Geographic are showing BA009 flight on Aircrash Investigation right now???

BRU FIR closed
 

Brussels FIR has been closed as from 14h30 z.
One controller told EBBR might be closed until tomorrow 16 Apr 18h00 z...
Tough times !

Question.....
 

So hundreds of UK outbound flights are cancelled today and maybe tomorrow. What happens to the flights on Saturday? Are todays and tomorrows pushed back to another time or will they take the place of the weekend flights?

Also, how does a charter flight fair? Are they easier to cancel and re-schedule or harder than scheduled flights?

Yes, if ash falls on the ground where you are, you would have to be concerned about vehicles, home mechanicals and the like.

This link discusses how to deal with ashfall.

@tilos

Volcanic ash is apparently microscopic in nature and not easy to see (so the BBC weatherman was saying), if so it's really insidious and you can see why it can cause problems.

Here at 60 deg N we can both smell and taste the sulphur.

Shall probably have to have recourse to whisky to refresh the palate :)

All engines are not alike when it comes to the effects of ingesting ash, anymore then saying that all volcanic ash is alike.

The variance is due to the various melting points of the particles of ash (vary with the volcano) and the operating temperatures of the engine when they ingest the ash. This is in regard to the largest risk which is the loss of power at altitude. Wear out modes due to errosion and blocking cooling holes take place over multiple flights and can be addressed by overhaul.

The gas turbine engine risk being dependent on its operating temperatures (in cruise) has been steadily going up as the engine designs get more efficient by running hotter.

To my knowledge there has never been a ash cause multiple engine loss of power for the likes of a B727, DC9, DC8, B707 etc. (perhaps explaining why some engines seem immune)

Small exec jet has just passed south of Aylesbury low level heading probably towards Luton. Hasn't seized up despite Comical Gord saving the nation from flying.

I've got a thin layer of fine grey dust on the cars and on my window sills - I can't remember if they were already like that and needed a wash or if it's the ash!
Hope it's all cleared up by next Thursday as I'm off on hols. Guess today would've been a good day to be at work after all - right until the airspace re-opens!

Does anybody know if there has been any sampling of the atmosphere to determine actual concentration of particulates?

Serious
 

:mad:

I do not think this is over reaction at all. :ok:

A gentle reminder here:

YouTube - Airsidetv.com - Interview With Capt Eric Moody BA Flt 9 Part 2/3

Apprently Brussels is covered with this stuff and the airport is closed. However, the weather is glorious and there is no sign of any dust.

Reminds me of Y2K.

Airborn Sampling
 

KiwiBrit,
a research aircraft is due to take off in the next hour or so to try and sample the plume over the UK.

Understand it is the NERC Do-228 ?

Well, we've just had a Spitfire launch from Duxford; perhaps it's a re-enactment of the THUM flights!

Interesting stuff here:

You can have a look at the "High Level SIGWX Forecast" and see the volcanic ash (Eyjafjallajokull) forecast for tomorrow 16-04 0000z. It's going South...

Well those blowjobs never were up to much. It's back to Spits in these days of crisis. This much be perfect for GA and anything VFR. They would love this to last into the weekend. Imagine circling over Heathrow in your para glider?

Here's a link to a real time ADS-B readouts over Europe. Notice how empty Northern Europe and the British isles is. Spooky! Give it a moment to load.

Spitfires aren't invulnerable to volcanic ash. The RAF had a few problems with piston jobs in Italy in 1944 when Mt Etna erupted.

Re Heathrow

Is it Closed as we speak ??

If it is I Think someone should tell Air India,Thai,Korean and EAT who according to Radar Virtuel are all en route to Heathrow or is it the Flight Plans are still as filed and they are diverting .

The Korean is going the wrong way as a natter of fact but why change the habit of a lifetime

Nature's Gritblaster
 

Lomapaseo

I think that the operating temperature of the engines would not be a factor.

If an aircraft were to fly through a cloud of volcanic ash at 500kts it would be equivalent to flying through a giant gritblaster...

The entire aircraft would be thoroughly abraded, including the turbine blades :sad:...

Nats suggested that the restrictions were unlikely to be lifted after 0700, saying saying it was "very unlikely that the situation over England will improve in the foreseeable future". BBC have also said, the airspace will be close indefinitely. Until the situation has passed.
