  1. Similar to related "behavioural / standards / ethics and most important, morality issues", with which many here and around the global village are concerned, the issues raised are also familiar and the testimony is not "news". Chuck Perrow was a pioneer in the eighties, opening up the discussion about "normal" accidents - well worth reading even now years after his passing.

    To me and I believe many, if we pull hard and long enough on the thread, many issues seemingly unrelated would unravel together. That means there is also a common solution, but the fortitude to "abandon all irrationality in favour of curiosity, thought and temperance" has yet to clear the majority's nostrels.

    The way forward is not as obscure as we think but it requires 'giving' rather than taking or demanding. The strength is hard to muster, to look the other way with an imperceptable shrug - not of resignation but of the will to respect the larger "fight" and understand that in nature there is no concept such as "winning". Not always, but these days such grace is infrequent, no, it's rare. In my tiny slice of experience, "positional bargaining" never succeeds in the long run nor does yielding to the temptation to instantaneously defend one's 'self' regardless of sources, without discretion as to the subtleties of which most are capable and in which the Venn Diagram can be used to show commonalities, as in, "If we were to confess our deepest fears, insecurities and foibles to one another, we should all enjoy general laughter at the lack of originality".

    Sorry for the drift.

  2. Post to mention this Webinar of possible interest, by AW&ST
    Complimentary Webinar:
    5G: A Threat to Aviation or
    the Future?
    June 12, 2020
    10:00 EDT | 15:00 BST | 22:00 SGT
    The U.S. has found itself in bind after bind over the issue of 5G networks. An FCC decision to allow Ligado Network to build an L-band ground-based 5G cellular networks is under fire from industry groups, airline pilots and even the Pentagon over the potential for its signals to disrupt GPS devices. And the U.S. military is at odds with the UK’s use of Chinese 5G equipment, with officials saying it is a security risk. So how will the U.S. and its allies realize the benefit of faster networking technology without harming the security of its own networks or GPS - the world’s most ubiquitous positioning, navigation and timing satellite.

  3. And it appears as thought it was "unbelievable" to the crew as well.

    The Mangalore Air India Express B738 and the Garuda Yogjakarta B734 overrun accidents were both higher than 200kts across the fence.

    So, the "belief" that solidifies into "we can make it" when everything the airplane is "saying" is that it can't/won't work, is a human factors / cognitive state that needs investigation all on its own, beginning with strategies for "breaking through" the tunnel - vision.

    I have heard that calling the other crew member's name first, then stating the concern loudly, works. 

  4. Hi Turbofan - okay, that answers the question, and is also the way one would expect the system to work. Thanks!

    Hi Vs - could be, yes. the temp was in the mid-30's, westerly wind. The marks on the runway from the pods seem though to indicate a "gentle" touchdown, (low rate of descent...a "skimming" rather than a hard (high rate) hit on the runway. Could just be that lucky point in the high descent path at which the descent was arrested - but again, there are two distinct pod-strikes about a few thousand feet apart. The FDR & CVR will help with the go-around questions.

    Stay well, all...Corona's jes' restin' for awhile...

  5. Re "gear up", there is a comment that bears examination re the A320...if the gear is selected down but the airspeed is > Vle, the gear stays up even as the handle (switch, really), is DN. The key point is, once below the Vle speed, will the gear then go down, or must the handle be recycled? No current FCOM...anyone?

    I think we have to consider "tunnel vision/tunnel hearing" in terms of human factors, stress and recency (don't know if this was this crews' first flight back after Covid-19 isolation), so aural/visual warnings may not have been "seen/heard".

  6. Also, for IOS users there is "Sky Guide", an app that uses the iPhone's gps & acceleration capabilities to "map" the sky above one in real time, (just like apps that can tell one what an aircraft going overhead is, where it's heading and so on, like FR24).

  7. So far, there doesn't appear to be video of the first approach/go-around yet so we don't know the position of the gear at the moment, for the initial approach.

    The appearance of the bottom of both nacelles show a blackened area, spreading out towards the rear of both engines. Recent images, (JetPhotos, January 2020) show clean nacelles on the bottoms of both.

    Those familiar with the CFM56 engine know that the Accessory Gear Box is on the bottom of the engine and IIRC, there was a drain or a breather at the bottom of the engine, something we were reminded of in training when considering roll at touchdown esp. in crosswinds.

    Anyone here know if damage to the AGB could result in loss of engine oil?


  8. From the CBC story linked above:


    Fly-by-wire technology has been the industry standard for both commercial and military aviation for a quarter century, but it's not without its problems. Its use (or perhaps misuse) was a major factor in the 2009 crash of Air France Flight 447, which killed all 228 passengers and crew.

    In terms of an objective, evidence-based investigation standard, I thought the question in this article was being kept open regarding this accident and the Cyclone design, until I read the above statement.

    The statement invites any reader who is just trying to understand things and who likely will not know details of the AF447 accident, to draw a "conclusion of equivalence" between "FBW" technology and this tragic Cyclone accident, inappropriately using an accident, AF447, that had nothing to do with FBW technology.

    The bracketed statement, " (or perhaps misuse) " more than suggests fault in advance of established facts.

    This neither serves flight safety goals nor respects the loss of life, both of which demand the very highest of investigative standards to establish where corrections are to be applied.

    The politicization of everything including science, the principles of evidence-gathering and the casting of darkness over earnest, experienced, expert efforts to find out things before pronouncing on them appears now to be a media standard.

    Repetition of the same mistakes, same causes of accidents and same conditions for disasters is the inevitable and predictable outcome of declaring causes prior to understanding what happened.

  9. Opening this interesting topic a bit to see more than Boeing/Airbus/Embraer/Bombardier etc., etc. - I'm wondering what a future looks like when aluminum & fuel weigh & cost more than pixels and sound bytes.

    Most here probably have had by now a similar experience within families, but we just finished an AGM meeting with a company that was conducted entirely online in which ALL employees are now working from home.

    Our adult children may have asked Mom and Dad what a typewriter was; will our grandchildren ask their M&D what an "office" is?

    Covid has jammed economic models and MBA learning right up against solid institutional rock, forcing people to learn/do with iPads & tablets what would ordinarily take years/decades to get people to do.

    It doesn't take a lot of imagination to ponder what that means for businesses that move and house & feed people when they aren't home. 

    The picture as we know & see it presently, isn't pretty but neither was the late ninetheenth century a pretty one unless you were Henry Ford.

  10. Agree, blues...and I think ">65" isn't permitted in the left seat in the U.S. (or in U.S. airspace).

    I missed the opportunity to stay by a few months. I suppose since I'd signed up in '73 for "60" that that was kinda that - off the conveyor belt for those behind, still on it! 😄
