Unfortunately Jim French didn't go into anymore detail (it was only a 2 minute interview) but hopefully someone on here will know about the FAA rules? (guidelines).
|
More teasers coming from Eurocontrol's tweeted messages.. Regarding "negotiations"... Hopefully there will be some real news this time. Press release coming soon
Better news i hear, new maps anyone ?? |
Sorry about that "Over Brecon" bit. In normal circumstances you would obviously have a point and normally I would not bother reporting an aircraft making Brecon, although apparently being the only commercial aircraft in UK airspace does give it celebrity.
What I should perhaps have said, rather than taking the short cut, is that it is interesting that BA seem now to be mounting positive steps towards understanding more clearly what we are up against and that the only aircraft currently visible in UK airspace does seems to be said BA test flight, which happens to be flying cautiously over Brecon. This looks like a positive move from BA and I hope it sheds some light. Rgds |
Hi all,
personally I´m more on the restrictive side. Nobody knows exactly how to compute this "cloud* and how to deal with different concentrations in it. In the last 50 years we never had such a occurence over Central Europe. I'm wondering, beside the reports of the finn F18´s, have there been any reports or remarks from flight crews around, regarding volcano activities over Europe in the last few day? Do some crew encouter subtle indications of ash in the air, especially in the night before grounding? thanks Bernhard (LSZH) |

Why no media coverage of the Katla seismographs going crazy? Is it significant?

Apologies to all I may have offended - it's just getting very difficult to track what's happening. A little bit of "Less is More" might help - focus on where your input actually gets anyone.
I think we need substantial information from "The Authorities" rather than innumerable personal views [however valid many of them may be]. |
BA 747

Totally agree. What is needed is data and those who govern the airspace to justify their decisions based on that data. Surely that is logical ?

BA 747 on its way back into cardiff, now over western Ireland the BA test plane has now landed in CWL and i imagine undergoing checks. BTW, they are called aircraft, not planes. |
Turboprops and ash
"......but could it be said that they are somewhat less vulnerable to damage from the ash cloud" I await admonishment with trepidation. |
Aha - a 'hard decision'. Are you quite sure that shouldn't be 'tough'?
1985 - you are Gordon Brown. Meetings will now be convened all over Europe amongst aviation authorities to decide the best way of agreeing a party line to allow a relaxation of restrictions without openly admitting the massive over-reaction in the first place. |

@ Admiral 346:
It could be rather helpful to know what the aircraft has survived, yes? For the future, like? |
hartman and simple solution
I tryed to find out what mr Hartman ment with his statement about NASA.
http://www.csmonitor.com/USA/2010/04...ful-study-says. 2 PAGES Between the text are statements from nasa and in contradiction what Nasa could say about the nowday situation to my opinion. Most interesting question of the moment is how much dust is within the bandwith of responsible flight operation. I think not a easy answer to formulate, the maintenance is an issue and safety. so there should be 2 answers. 1.for meantenance in fact financial issue ask the company 2.safety i think is easy. actually there is no risk to my opinion. The risk of not follow maintenance when the equipment (aircraft) is used in dust Thats the risk for this moment. And what different maintenance and inspection !! Its a simple point of vieuw, many times for difficult things can be found easy solutions. Separate the fleat used in dusty conditions and not dusty conditions and separate the maintenance programm. WILL IT SECURE THE SAFETY OF PEOPLE FLYING IS THE QUESTION is that basicly a solution? |

At the risk of squandering what little credibility I have by posting on this thread, I need to explain something to some of you.... The fact that someone can make a "Test flight" and return the aircraft in one piece after exposure to some level of volcanic ash proves absolutely nothing. Detailed examination of the hot section of the engine is required, probably right down to the microscopic level and including sectioning of first stage turbine blades and nozzle guide vanes to check the cooling passages for contamination. I'm not sure what turbine blade life is these days, but it must be of the order of at least 6000 hours plus, and probably well over 10,000 engine hours. If volcanic ash contamination compromises the figures for blade life in the slightest then airlines cannot fly because they are buying themselves a simply massive maintenance cost increase in the future. Furthermore, there would not be enough blade and vane manufacturing capacity available to satisfy demand. To put it another way, I can take the air filter off my car and still run it up and down the road today and nothing will happen, however I would be wrong to conclude from that experiment that the provision of air filters by the car manufacturer was unnecessary overkill designed merely to boost profits. To put it another way, If the engines will get their lives shortened by dust contamination, then the aircraft cannot fly, at least not at todays ticket prices anyway. To put it another way, the operators already make decisions like this on a real time basis everyday. Perhaps we can revisit this months from now. |
It's approaching STU at FL150 inbound to EGFF.

Sinking Feeling....
Safety is the number one priority for us all in the industry.
Of course, this unfolding drama is doing untold damage to our industry, however I am getting a bad feeling (especially listening to Euro Controls press conference and taking into account all these TEST flights by legacy airlines), these commercial operators could be attempting to persuade the powers that be to relax the restrictions already in place, just for the sake of reducing the rate of cash burn, thus having a detrimental effect on safety. There is plenty of evidence published that states volcanic ash does untold damage to a turbine engine, and can lead to multiple engine failures. KLM Lufthansa and British Airways are not exactly independent entities. I agree in the authorities decision to ground aircraft, especially considering the severe risk associated with volcano ash. I just hope their resolve continues and will not allow the "BIG BOYS" in the airline industry to pull sway on what effects ALL aircraft sharing the same airspace. I hope someone can ease my concerns, your comments welcome. High Low |

Tens of thousands of crew and pax are screwed, jobs are on the line [or possibly over the line], commerce is being damaged ... and frankly the individual movement of a single aircraft, waypoint by waypoint, doesn't seem to help develop an intellectual perception of where we are. The Eurocontrol statement possibly will. |
The bottom line is ..........It's not safe to fly through volcanic ash, and no one can predict with any confidence where it is likely to be present at any given time.
Accept it and deal with it, if it hurts your pocket.. tough := |
