    WRT to previous eruptions I would like to add the following information.

    There have been very many more than 20 eruptions in the last 100 years. Popo, Santa Maria, Sangay, Soufriere Hills, Fuego, Tungarahua, and a few others spew pretty much continually in Central and South America. Not the volume of this eruption, but eruptions nonetheless. This problem is managed by the airlines by basically flying upwind. Please note that a lot of the North American/South American flying is conducted at night, when the ash cloud is not visible (and radar doesn’t detect it). SJU often reports ash in their METARS……still the airlines operate until it get too thick and they decide to stop.

    Last year, a major eruption occurred on the Kamchatka peninsula, which affected R220 and many other heavily traveled airways between Asia and the U.S. There were a few diversions and traffic was disrupted for a day or so, but nothing occurred like the total airspace shutdown from this event. Basically, the responsible party (the airlines) flew around the ash.

    When Mount Pinatubo and Mount St. Helens had major eruptions, there was not a total airspace shutdown for a week like in this case.

    To my knowledge no airline had an actual ash encounter in this event. There were a few military encounters in this event. Test flights flew for several days with no problems – yet the airspace was still closed.

    I’ll stick by my assertion that the air traffic service providers (whose primary responsibility is traffic separation) stuck their nose where it didn’t belong, into an environmental/meteorological situation that is the responsibility of the airline.

    Also, no one has mentioned: What about the EU? Why did the individual countries respond individually? At what point will the EU have control over the civil airspace in all of Europe?

    Is it an unacceptable political statement to say unaccountable government ATC technocrats cost companies hundreds of millions of euros for no reason?

    I guess I’ll know if my post gets deleted.

    It’s hard to believe how badly the ATC bureaucrats in Europe fouled up this time, misled by meteorologists with bad data…..it looks like they won’t be able to hide it too much longer.

    Can any one categorically say it will be safe to fly into the ash cloud ?
    Its all just supposition we just don’t know what will happen , better to err on the side of caution than be proven wrong
    Remember if we are wrong peoples life’s are at stake ,maybe even you’re own

    Peoples lives are always at stake. No one can categorically say it is safe to fly…..ever. There is always risk to be managed. IMHO, the problem with this event is that someone very important made the blanket statement that it is NOT safe to fly, when there is very little visible ash aloft or on the ground at the various airports. The important considerations are how much ash is present and where?

    You are correct….it is all just supposition. But at some point, some level of risk has to be accepted. The easiest thing in the world to do is ground the airplanes……in normal ops the easiest thing for a controller to do is say their sector is overloaded……….in normal ops the easiest thing for a pilot to do is refuse an MEL…..but they don’t pay everyone to do the easy thing. At some point an operator has to make an aviation judgement and deal with the consequences. And it is appearing more and more like those in charge of the airspace have made a ridiculously conservative judgement. Keep in mind that this volcano may blow for months, at some point they are going to have to learn to manage the situation instead of just making the easy decision to bring all the traffic down.

    Interesting…..

    However, in our reality the restrictions weren’t imposed by politicians at all, but by ATC professionals.

    “our”??

    You’re now speaking for everyone on the forum? Another case of administrator/poster confusion?

    But to your point, last I checked ATC was ultimately run by politicians. I can scarcely think of anything more political than ATC. But then again, I’m not claiming to speak for everyone.

    IMHO this event is a classic example of over-reaction by non-aviation type politicians, responding to less than (very much less than) well understood meteorological phenomena. It’s eerily like the global warming “junk science,” and should serve as a warning to all of the power of science run amok.

    The reality is that risk assessment goes on every day. Last year when the volcano blew on the Kamchatka peninsula, there were some problems but not the blanket shut down like we have seen in this non incident. In my previous post I commented upon the number of active volcanoes in South America that airlines evaluate and fly around every day. The airlines generally manage pretty well, and they are ultimately responsible for the safety of flight (when was the last time someone sued the government after a crash, the airline always get multiple lawsuits).

    IMHO the BA 747 encounter of almost 30 years ago has very little to nothing to do with this event. There have been thousands of eruptions, and hundreds of actual VA encounters by actual aircraft since that time, with very little of the dramatics involved in that encounter. VA is much, much better understood than then, and the airlines as a whole have done much, much better than they did then. The veracity of my claims can be substantiated with 15 minutes on the internet with any good search engine.

    This is all just my opinion, but I don’t see where any of these blanket airspace shutdowns was justified at all. I predict more and more “test flights” until the reality sets in that this whole event was the result of a ridiculous error in judgement. If the volc keeps blowing for months, eventually the authorities will let the airlines manage it they way they already do in other regions.

    At the risk of agreeing with any earlier poster who said a lot of things that were ridiculous: Does anyone think the authorities have over-reacted in this case?

    As far as I know, only one airport has actually reported any ash on the field, and I think that was Aberdeen (but admit I am not sure) and that was only for a very short time.

    WRT to the ash aloft, I wonder how many on this forum are aware of the number of active volcanoes in the world, particularly in South America, that commercial airlines fly around every day? For example, Reventador, Popocapetl, and Soufriere Hills come to mind. Soufriere Hills will occaisionly dump so much ash on San Juan airport that the METAR will report ash for days on end. And yet the airplanes operate. I’ve had pilots tell me that they there has to be low concentrations of ash in those areas, and they fly through them every day with no ill effect. In short, its not that VA exists, but is it present in sufficient concentrations to actually affect aircraft?

    Aside from the F-18 encounter, is anyone aware of any ash encounters from this event? Can anyone in Europe give a PIREP on ash that is visible from the ground?

    All in all, from outside the continent it seems an over-reaction by the authorities.

    The B777 will be fine, though some people on this forum have been less than complimentary about AA’s service.

    WRT to in flight service, IMHO most of the U.S. airlines suffer from far too many 67 year old flight attendants…..:)

    I’m guessing that they have a really good idea on efficiency at this point. I’d love to know if actual performance is what they predicted.

    Tommy, you are the rarest of the rare, an airline customer in the western world who actually looks beyond ticket price. In my experience, the first preference is price, followed closely by price, and then finally, price. So, if you want to go with the herd, pick the AA flight.

    Uh….note that they compared the 777 reliability to other Boeing products…..you conveniently truncated that part of the post.

    WRT to reliability of 777 at service entry, I took the following data off the Boeing website which says the 777 achieved the reliability levels out of the gate that the 767 and 747 took 18 and 38 months, respectively, to get to. As I stated in my previous post, I’m not just making this stuff up.

    777 Gets High Marks At First Operations Conference

    SEATTLE, Oct. 30, 1995 — The 777’s in-service report card so far is excellent, reported Dean Muncey, Boeing Commercial Airplane Group director of 777 Service Engineering, at the first 777 All Operators Flight Operations Symposium in Seattle this week.

    In its first three months of revenue service, United Airline’s 777 fleet has experienced a cumulative schedule reliability of 97.7 percent, he said. Schedule reliability is the industry measure for the percentage of time an airplane is free of mechanical delays and able to leave a boarding gate within 15 minutes of scheduled departure. This is a dramatic improvement over the introductions of the 767 and the 747, which achieved this level at 18 months and 38 months respectively.

    Sixteen 777 customers, other airlines and major suppliers attended the symposium, held five years to the week from program launch Oct. 29, 1990. The participants heard a number of Boeing reports ranging from flight tests and certification to action plans under way to resolve those few technical issues Muncey highlighted in his remarks.

    “We are very pleased with results so far, and attribute the airplane’s success to all the early-on accomplishments of working together with our customers. They deserve the credit for helping to design these systems,” said Muncey.

    An in-service experience report by United Airlines’ fleet captain Lew Kosich was a highlight of the symposium. “The 777 has shown itself magnificently during its first four months of service,” he said. United is now flying six airplanes, all powered by Pratt & Whitney engines.

    Kosich called the 777 the most challenging and unique in his experience. “Personally, I’m certified to fly 20 heavy jets, and my background has been in flight test. I’ve never seen a program go like this,” he said.

    “Working together was absolutely awesome,” Kosich said. “Our learning curve started five years ago. I don’t think a single person involved thought when we started that we could achieve ETOPS certification at delivery. But we did. When the airplane was finally inaugurated into service June 7, it was almost a non- event. We were inaugurating a mature airplane! Two of our inaugural flights were ETOPS flights.”

    The unique Working Together atmosphere extended beyond the design table where Boeing and its launch customers first met in 1990 and during the manufacturing process itself. The regulatory authorities, the Federal Aviation Administration and Europe’s Joint Aviation Authority were involved in early planning to provide concurrent requirements so important to ETOPS certification.

    Today, 50 percent of UAL flights are ETOPS (Extended Twin Operations) routes that could fly 180 minutes from suitable airports.

    “There have been some technical problems, but they’ve been minimal compared to other programs,” Kosich continued. “But ask any 777 pilot and you’ll undoubtedly get a glowing report! Across the board, they love flying the 777.”

    Kosich devoted much of his presentation to describing United’s readiness programs, including pilot training. He said that to meet UAL’s aggressive delivery schedule, United’s flight training simulators will be running 24 hours a day by next spring.

    United Airlines is the new model’s largest customer, accounting for 34 of the 187 orders. Since Boeing entered the market with its twin, the 777 has captured 79 percent of orders for this class airplane, outselling the A330 and A340 combined. All Nippon Airlines, second largest 777 customer, took delivery of its first 777 earlier this month. Sixteen airlines have placed firm orders for 777s.

    To Bemused and Bograt

    WRT to fuel icing on 777 aircraft, the only other similar incident that I am aware of was experienced by Delta Air Lines with another RR powered 777. The GE and PW powered 777’s haven’t experienced this icing problem, and they have esssentially the same fuel system on the airframe. Basically, miniscule particles of ice in the fuel system accrete on the RR fuel/oil heat exchanger and clog up the fuel flow. Apparently, the fuel systems on the GE and PW powered 777’s don’t have this problem…..at least none have been reported. If you can find one, please link to a report showing that a GE or PW 777 has experienced this problem.

    It’s all public knowledge….the reports are out there….even Wikipedia has this one mostly correct……I’m not making this stuff up when I say, and stand by, my statement: The only 777 hull loss accident was due to RR engines. If you prefer to be more specific and say “…was due to the fuel/oil heat exchanger on RR engines” so be it.

    Furthermore, I can’t find it right now, but Boeing produced a chart at one point that showed the delay and cxl rate of other airplanes verus the 777 from service entry onward, and the 777 was by far the most service ready airplane of all time (up to that time) when it was introduced. The GE90 was an all new engine at that time, it may have experienced some teething pain but not so much as to preclude 180 ETOPS approval from day 1.

    I think the early GE90 engines on the 777-200A airframes suffered from some reliability issues. (So much so, I was told, that this was the reason BA ordered RRs for their 200ER models.)

    I believe the 777 had the most trouble free entry into service of any type….at least that was the Boeing hype at the time.

    Further, I don’t recall the GE90 issues you refer to at all. IMHO the real reason BA switched back to RR (remember the uproar when they had the audacity to buy GE’s on the early 777 models?) was nationalistic in nature. And see what that got them: The only 777 hull loss to date has been caused by RR engines….. As an aside, the GE90 was really more optimized for the IGW 777 versions, due to the fact that it is larger and heavier than the other two competitors.

    Back to the original topic, I would hope even the most ardent A380 fan would agree by this point that the service entry has been somewhat of a disappointment, especially when one considers the 2 extra years Airbus had to perfect the airplane because of the program delays. And they STILL haven’t sold any more…..and now the Airbus leaders are even acknowledging publicly that the program is in trouble financially and that it will be years before the program breaks even. What an abomination!

    2. Not true. The entire US tank fleet is now equipped with licence-built guns of European design, which have replaced – other licence-built guns of European design. The Harrier, T-45, Stryker, T-6, B-57, M777 – I think all these are fairly substantial deals, & there are, as has been pointed out before, others.

    Shhh! Don’t interupt with facts when emotional U.S. bashing is underway.
