The A380 works for Emirates, but it doesn't work for any other airline, except for maybe BA, when LHR is at full capacity. The era of VLA is largely over and I just don't see Airbus or Boeing coming up with a plane that will help EK replace its A380s one day on a capacity for capacity basis. High f...
Jump to postNot quite true. Reynolds number has an effect on stall too. Airspeed and altitude effect Re-number . . . . Straight from the FAA: “It is important for the pilot to understand that a stall is the result of exceeding the critical AOA, not of insufficient airspeed. The term “stalling speed” can be mis...
Jump to postApparently STAB TRIM CUTOUT switch positions are not recorded by the DFDR, and so they cannot directly identify the position of the switches. Not recorded, because MCAS, as well as the pilots, can change. Likely MCAS will turn out to have three settings - OFF (procedure yet to be disclosed by Boein...
Jump to postActually If you have understood the mechanics of MCAS action you would trim electric by hand and switch off trim hard when reaching a workable position. Reality broke on the "know and understand" thing due to lack of information ( that was intentionally not provided ). That is why the pil...
Jump to postYES they are saying that they verified that the data they gave to the EAIB was accurate. They are NOT clearly saying that they agree with the characterization stated by EAIB. And, as I said, it would be unusual for them to make a characterization like this, on their own, this early in the investiga...
Jump to postWhat I gathered in articles I read, 240 manual turns to go from full nose down to full nose up I.e. 30degrees. So 80 turns from -5 deg to 0 deg. Plan ahead if you are going to spin by hand! If that is the case, it's potentially a problem at low altitudes even if you do manage to turn off MCAS after...
Jump to postNote how the release states that the data extraction was monitored by the Ethiopian authorities, the BEA and the NTSB, and how the investigation team noted clear similarities between ET302 and JT610. The "team", to me, would mean Ethopia, BEA and NTSB. That's what the Ethiopian AIB wants ...
Jump to postUntil the BEA (or NTSB) says it, I am absolutely not taking on faith the Ethiopians' assertions about this. These are the same folks who still believe their cluster with the -800 was an explosive device. Or I shouldn't say "believe" it, I should say "asset" it. They're racing to...
Jump to postDominic Gates despite being the home town reporter, never lacks in objectivity. That article is indeed a shocking read. I can't think of a person more nonobjective towards Boeing than Gates. It's a shame he gets as much air time as he does. A true disservice to society. Tried and tested approach - ...
Jump to postThis isnt a minor issue, this is something that was so obvious that if there was a fault etc it could put the plane in danger that you have to ask how the hell did this not come up in risk assessment. My point exactly - considering the characteristics of MCAS that Boeing is now fixing (limit trim i...
Jump to postFrom there on, the main input by the crew was to pitch up, even though the stall warning was sounding all the way through. . No, the stall warning would shut off at high angles of attack. It would turn on as the nose dropped and the plane could measure airspeed again. So pulling up turned *OFF* the...
Jump to postWhat worries me is all those who keep saying ”a pilot not knowing about this issue has been in a cave for 4 months”, ”it’s a training issue”, ”it’s because the F/o had 200 hours” etc. A plane should not fly itself into the ground, switch flicked off or not. Such as AF 447 doing so from all the way ...
Jump to postFinally a couple of people who’ve not been drinking the Kool-Aid. This whole thing is a disaster for Boeing and they should have been more proactive in dealing with it. It’s looking like their version of VW/Audi dieselgate. Not a valid comparison at all. The emissions control software worked exactl...
Jump to postMCAS is not the cause, but it gave the final blow There's rarely a single cause, so in that sense you're right. But all other things being equal, there is reason to doubt that we'd have more than 300 people dead without MCAS. (Yes, I know, we are not 100% sure MCAS even played a role in ET302, but ...

Jump to postHow do people still not get this? Flying in a given airspace is a privilege. Not a right. As such the burden of proof to show that the aircraft is safe enough to operate in a given airspace falls on the OEM. Which was already done during the cert process. It seems you have an interesting view of wh...
Jump to postYes, they are called incidents. From the beginning of aviation time. No, they're not. ET302 and JT610 are quite definitely classified as accidents. There is a marked difference between incidents and accidents in aviation speak. There is even the sub-category of "serious incident". There a...
Jump to postFrom Boeing's statement: "Boeing has determined [...] to recommend to the FAA the temporary suspension of operations of the entire global fleet of 371 737 MAX aircraft." So the manufacturer makes a recommendation to ground the fleet to the authority that's supposed to regulate that manufac...
Jump to postBut Lion Air crashed two airplanes just a couple of months apart. So are you saying the 737-800 and -900 should be grounded as well because Lion Air had a number of runway excursions (one ending in water) with them? No? OK, I was worried there for a second you'd lost all sense of commensurability. ...
Jump to postWhy were the previous two Lion Airncrews able to handle the same situation? Now you're finally starting to ask questions that begin to head remotely into the right territory if you're actually interested in finding out what chain of events led to the loss of life of almost 200 people with JT alone,...
Jump to postFWIW, I'm very surprised that so many seasoned posters here are surprised about the grounding. Doing things based on established knowledge about the root cause of accident is a fine way to approach things, but so is doing things based on the lack of knowledge in the face of accidents. Abundance of ...
Jump to postWhat do you want Boeing to fix? There has been no cause released for either accident. Why is it Boeing's fault of it turns out it was due to faulty maintenance or crew error? Even the FAA, who hasn't grounded the MAX so far, wants Boeing to fix MCAS. The way MCAS works has already been identified a...
Jump to postThat would be a domino effect combined with social media pressure. They are not stupid. Makes them look good. The fact that people dismiss this so easy yet are writing Max off without ANY undeniable proof as to what caused the accident tells everything. Who is writing MAX off? The consensus at this...
Jump to postAgreed. There are no facts yet from either crash to put the blame on Boeing. People just want to see Boeing hurt. Honestly, I don't. And I'm sure EASA and others don't. That doesn't come into play when deciding on groundings, though. Aviation authorities don't appoint blame as such, either. They ar...
Jump to postConsidering it was China that banned MAX first its easy to say this has nothing to do with safety. Just a perfect tool to strike US/Trump trade policies. Just my opinion. Than why would the UK ban these aircraft? They are about to leave the EU, they need a new trade deal with the USA asap. Its fine...

Jump to postIn the end, a whole new type certification may be required, and that will kill the program. Did you know that the 757, 767 and the 777 share a common type rating? Don't confuse type rating with aircraft certification! Also, the common type rating is only for the 757 and 767 - not the 777, although ...

Jump to postBut going off the 1 out of 175 is a bad way to look at the statistic as these planes had successful flights before hand. If you go off accident rate per flight and just estimating 350 Max aircraft X 365 (average) days in service X 2 flights per day = 255,500 flights. 2 / 255,500 ~ .00078% accident ...
Jump to postJT prefers to take theirs off-roading and swimming. They are a dumpster fire of an airline on so many levels. Eu hrs haven’t change and neither has their accident rates. Whereas the US has a perfect record the last decade. And yet you have failed to point out a single instance of a EU-registered pl...
Jump to postFAA has announced they will issue a CANIC for the Max.....Sounds fishy to me! https://mobile.twitter.com/FAANews/status/1105192183244750849 A CANIC may just be a message saying "Oh, we're looking at it, stay tuned." FR24's Twitter gave an example: https://twitter.com/flightradar24/status/...
Jump to postTotally agree! The US requires 1500 hours to sit in the right seat of a CRJ, I thought they inadvertently dropped off a zero when saying how much total time the FO had. 200 hours !?!? Are you kidding me? I agree the 737 Max should be looked at with suspicion, but so should the low pilot standards i...
Jump to postWhen we know the causes of the two crashes, then we can talk about taking action. Taking action before you know the causes, is not a good idea. That's not really true in a lot of circumstances. It's often wise to take some action you know/hope is going to stop the adverse effect you're seeing even ...
Jump to postOn a side note (and I've never really had this type of concern before) I'm kinda worried about the CVR and FDR integrity. Considering the fragment size at the crash site, I'm kinda left scratching my head at how anything the size of those boxes could survive. I realize they're solid-state, and they...

Jump to postNow that Airbus has nothing to offer above the A350-1000, the market is all in Boeing's pockets. I disagree because of the following two points: 1) The market above the A350-1000 simply doesn't appear to be that large. It's covered by the A380, 747-8i and the 777-9X. All cancellations accounted for...

Jump to postNeeding 2-300 orders for a launch seems a lot, although creating 'orders' via conversions from other orders does help I thought the same. Maybe Airbus wants to avoid an A318 Mk 2, i.e. costly sub-programme with little return. It does make me wonder what the programme cost would be, though, and thus...
