Learning to live with ash

There was so much criticism of the CAA and 'authorities' in general about their handing of the first ash crisis that many journalists picked up the cause both for and against.

The facts have probably now caught up with the rhetoric and there appears to be an accord between the various bodies including aircraft / engine manufacturers, operators and regulators that enable proper quantitative and qualitative decisions to be made. During the weekend, some trans-Atlantic flights were delayed because of re-routing north of the affected airspace but the flew and flew safely.

Today, we hear from Ryanair that they have temporarily grounded two aircraft where ash particles have been found in the engine nacelles. Whilst obviously disruptive to schedules, this is a very positive statement. It shows that operators are monitoring and know what to look for and, most importantly, what is and what is not an acceptable level of contamination.

For the passengers stuck on the ground at British airports unable to fly to southern Europe, these advances will be of scant comfort. Also, those people planning to fly later in the week who are being warned of possible delays and cancellations will continue to curse the whole aviation industry. But, let us give credit where credit is due. We have come a long way in the last month and there is now a much better understanding of living with the ash problem.

It is likely that we will have to learn to live with these disruptions. The Icelandic volcano continues to disgorge it contents, albeit at a much lesser rate; and metrological clearance of the ash is a much slower process than most of us anticipated. Short-notice closures of airspace; re-routing and more frequent aircraft checks will impact schedules but aviation is working again and working safely.

The volcano was not a man-made problem. Having been on record criticizing the lack of preparedness, I am now quite impressed by the way that the industry has pulled itself together.

I sort of agree but am pissed that they did not get this right before hand. I got stuck and lost time at work and did not get paid. They knew that these volcanos could do this and so they could have known before what was safe and what wasn't. But, yes, safety was a good thing to get right.

The CAA should be applauded for the way they have handled the situation, its nice to know that they put passenger safety above airline profits.

I was very annoyed when everyone got stranded and blamed the government for its failures to have anticipated the problem and for its complete mess-up of getting people home etc. But, yes I can see that the CAA did a pretty good job this time and that they did stop the airlines taking improper risks.

Latest info from the met office:
Meteorological Office indicate that the volcano is no longer emitting any ash but only a steam plume of up to around 10,000 feet. As a result of this lower activity, UK airspace is not expected to be affected.
Volcanologists and Geologists term this quieter spell of volcanic activity as a ‘paused’ phase. However, it is typical for a volcano like this to have several ‘pauses’ as part of its overall eruption phase. Only when the volcano has been ‘paused’ for three months will it then be regarded as being dormant.

We may well have to learn to live with ash. As the Eyjafjallajökull volcano is gradually subsiding, scientists believe that the eruptions may trigger multiple neighbouring volcanoes and the resulting ash clouds could be a lot worse than we have experienced from Eyjafjallajökull.
A scary thought, but at least the CAA and airlines/airports now have legitimate safety procedures to handle this in the future.
