^^^ ok so with that info and apparently how easy it is to disable the trim or a failing mcas system due to faulty sensor inputs....how did these pilots allow the plane to fall out of the sky? Some replies I got earlier made it seem like you cannot manually fly the 737max?!? I wish I knew why it was...
Jump to postYou forgot to add "by luck"! They had no idea what was going on but happened to guess correctly that trim could be involved. THERE WAS NO PROCEDURE. Just absolutely spreading lies. They didn't just blindly guess. They made an educated decision based on experience and the situation. The tr...
Jump to postThe likes of Southwest (and maybe RyanAir) have held the 737 program hostage for too long. We're seeing the dark side of free market economics with Boeing still prattling around the 737 in the 2020s at the behest of these carriers unwilling to spend the dime to look forward. How many more incidents...
Jump to postStill so much focus on MCAS. While there is always a chance that MCAS may be involved on some way, if the flaps are extended, MCAS is designed to be disabled...which means that the sensors which trigger MCAS, are irrelevant in this case, as would be their potential failure modes. If the flaps were ...

Jump to postImproving MCAS doesn't necessarily make it the cause of the crash, though. From what I recall from the Lion thread, MCAS is disabled when flaps are lowered and/or auto pilot is engaged. As well, it can be manually disengaged intermittently with the electric trim switch on the yoke, and permanently ...
Jump to postThis is the part I still don't understand. Everyone keeps saying "safety first", "safety is our top priority" and all that crap, and yet actions are the complete opposite. You want to save the faux horror, and keep on flying until we know more. Fine. But what if there will be an...

The end of all of this, is that if you don't trust the data, fly the plane manually.
If you fly manually, I believe MCAS can engage without warning or prompting if triggered.

Jump to postWith 350 or so MAX's flying, if there was any significant inherent issue with the MAX, I think it would likely have shown up by now. We'll see. You mean by having 2 of them crash within months of entering service? Sorry, couldn't help myself... but potentially it already has shown up, with the wors...
Jump to postHere is my take: there is a design fault in the 737MAX MCAS that manifests itself only under certain malfunctions (invalid AoA value). There is a pilot memory item that will disable MCAS under those malfunctions. However, it is not good practice to circumvent design faults by memory items. Boeing w...
Jump to postThere's has been a lot of mention of MCAS. Does anyone know if it was enabled? Were the flaps fully retracted? If the flaps were deployed, MCAS would have been disabled. Some reports seem to indicate the problems started immediately, or very shortly after takeoff. If so, it seems unlikely to me, tha...
Jump to postFR24 has only first 3 minutes of the flight recorded, the rest of the flight was out of their coverage. The pilots reported they had unreliable airspeed straight after the take-off, which might have resulted in the pilots retracting the flaps and MCAS to kick-in, with possibly faulty AoA data. It s...
Jump to postCorrect me if I'm wrong, from what I recall of the flightradar24 plot, the aircraft didn't get much higher than 1000 -1500' agl. Would they have retracted the flaps that low?

Jump to postFlight ended at 8600' according to flightradar24. If accurate, it's not the same profile as the previous MAX accident...more like CFIT.
Jump to post6 minutes into the flight...would the flaps have been retracted yet? If flaps were extended, MCAS would have been disabled. Playback shows flight ended at an altitude of 8600 ft...quite different from the previous MAX accident.
Jump to postMuch like the Boeing 787, perhaps the PW GTF will be known as the miracle worker with a rough start. And just like Boeing and the 787, I wonder if PW feels in hindsight they should have done more themselves instead of more risk sharing and outsourcing with partners. Time will tell, but I have the f...
Jump to postI think the XLR is a smart move. Since we're in a guessing mood...here's my take. A quick and dirty upgrade has very little downside. Besides some minor aero tweaks, I think it will auger in their version of split winglets which will not just clean up the wingtips but add some extra span and area, s...

Jump to postIt only happened because EK had to avoid the A380 cancellation penalties. Unless that narrative has been proven, I doubt it. Airbus benefits greatly from the cancellation of the 380 program. Every aircraft was produced at a loss, and the loss was not only getting bigger in total, the loss per aircr...
Jump to postThe really really big win for Airbus here is that EK has validated the A330neo as a competitor to the B787. That is a big boost for the 330neo in future contests. Boeing tried to strangle the 330neo at birth (the HA deal for example) because it knows its strengths, and the EK deal means they failed...
Jump to postMy comment is; you can't change the past. It does look like both players have learned from it, though. Airbus gambled on the 380 and they lost. It happens. The deal is done, the money spent and the 380 saga is coming to an end...and now we can move forward. On the other hand...I wonder how many fish...
Jump to postAirbus has taken the first step into 'what's next land', by cutting the losses of the 380 and freeing up capital and resources. I would be completely stunned if they didn't have a few all new MOM concepts of their own kicking around backstage...besides any 321 mods they are planning. I don't believ...
Jump to postAirbus is now pretty much entirely depended on the 320, 330, and 350 (A220 to a lesser extent). This has been the case for a few years, ending the 380 just formalized the status quo. Boeing has the 737MAX, the 777X, the 787, the 797/MOM project. I'm heavily interested in seeing what the next thing ...
Jump to postI look at the GE-9X vs Ultrafan as being a similar competition between the GTF and LEAP. No doubt the gearbox is a real game changer, but so are exotic materials. I think RR's geared fan will provide the bulk of the efficiency gains on the Ultrafan and the bulk of GE's gains will come from gains der...
Jump to postI don't know why people keep on bringing up that there were any potential penalties involved in this deal. It would have been way worse for Airbus if EK had insisted on taking all of those 380's they ordered. Not only are they losing money now on every 380 that goes out the door...they would have lo...
Jump to postI saw a cautionary video of the dangers of not immediately bottoming out the collective when the engine quits. A low time pilot was on, I believe, a solo training flight in a Robinson. The video clearly shows his main rotor stop turning, and the blades fold straight up as the helicopter plummets fro...
Jump to post2024 for A350 is very close to 2025 with upgraded engines. Is this the start for A350-2000 with new engines? I fully expect EK to be one of the first airlines to get 350Ultras. RR saved themselves a ton of development time, effort and money by nixing the variable pitch fan and making it a straight ...
Jump to postAnd they say politics makes for strange bedfellows. I think Airlines have them beat.
Jump to postSo they are ordering the oldish A330Neo... A real downgrade compared to the 787-10... Sad for the A380 :( Well...they also have the oldish 77X on order.

Jump to postAs it stands, Airbus loses money on every aircraft it makes. Patently untrue. Airbus made money between 2015-2017. It was pretty clear that I was specifically speaking about how Airbus loses money on every 380 sale, not that Airbus loses money selling every aircraft they make. I suspect that Airbus...
Jump to postIt's interesting how all the ultrafan speculations were for them to be on the A380neo, but then Airbus goes ahead and ends A380 production and gets those engines on the A350 instead. Airbus is going through a huge strategy transformation. Actually, the Ultrafan applications always included a 350neo...
Jump to postThere won't be any penalties. If Airbus was to be so petty...Clark would most likely just eat whatever upfront money EK gave to Airbus, ignore the 350 and go with 777's and 787's going forward. I doubt they would even take the ones already in production, and dare Airbus to sue them. This is going to...
Jump to postTime to get a ride in the whale before it becomes a lot more difficult! Sad indeed. Not to worry. 380 production will end but 380 service will continue for at least another decade. Once mainline airlines start retiring them, all won't be immediately turned into beer cans. At least a few will be pic...
Jump to postI suspect that Airbus will announce the end of 380 production soon...and at they will have a ceremony bidding it adieu at the Paris air show. Multiple folks have said this and I can't quite imagine it. Businesses like to look forward with their PR, and to look back only when it is in the service of...
Jump to postThere is no forecast, plan, roadmap, scenario or possibility that makes the 380 profitable...ever. The only question is; how much loss is acceptable before the line is shuttered?

Jump to postI have little doubt that the writing is on the wall regarding the future of the 380. I think all that's left is working out the details. My guess it will be announced before Paris, where they will have a big 380 farewell presentation.

Jump to postI think the -10 will be more of a victim to EK downgrading its expansion plans than any performance deficits. I also think that it was always most likely that they would either go for the 350 or the 787, but not both. The swap of 380's for 350's pretty much makes the choice for them. Emirates is fac...
