Here's Pratt & Whitney view.
While P&WC acknowledges that the Local Regulatory Authority has the final determination of whether flight operation is to be conducted, we want to inform you, our customers, of potential hazards.
P&WC does not recommend operation in conditions where volcanic ash is present. Let us explain why.
Volcanic ash may clog air filters of turbine engines, block cooling air passages, erode the gas path components, and erode the protective paint on casings. Volcanic ash entering the engine can also melt in the combustor and then re-solidify on the static turbine vanes, potentially choking the turbine airflow and leading to surging and an in-flight shut-down. It is also noted that there is a high level of acidity associated with volcanic ash, and this may also lead to deterioration of engine components.Should you experience an encounter with volcanic ash, P&WC advises you follow the recommendations contained within the engine maintenance manual.Peter BoydChief Engineer, Customer Supporthttp://www.pwc.ca/en/service-support/engine-operation-in-volcanic-ash
What are we exporting????, besides jobs?
Iceland volcano air restrictions are excessive, says European Commission "Europe should reduce its volcanic ash flight ban to “several dozen kilometres” around Iceland and rethink the Met Office science behind the current no fly restrictions, said a senior European Commission official today." http://www.telegraph.co.uk/travel/travelnews/7607216/Iceland-volcano-air... http://www.pprune.org/rumours-news/412103-ash-clouds-threaten-air-traffi... "Germany's Lufthansa and Air Berlin meanwhile expressed industry anger on Sunday that decisions to close airspace were not based on proper testing and that their aircraft showed no signs of damage after flying through the ash-strewn skies without passengers. "The flight ban, made on the basis just of computer calculations, is resulting in billion-high losses for the economy," Lufthansa spokesman Klaus Walter was quoted as saying." http://www.breitbart.com/article.php?id=CNG.2f1d9530f7c5fe558f8020be9e3b...
So, I wonder how the IMF officials from Washington DC to Athens if they cannot fly across the Atlantic on a commercial flight?
Sky New sources understand plans are in place to open Scottish airspace at 0600, Midlands at 1200 and Southern UK at 1800 on Tuesday.
Let's just call it Icesave's revenge. Time to wake up UK and inhale the karma.
