It will only be able to erroneously activate if BOTH AoA sensors fail and indicate false nose up attitude AND they both fail within 5.5 degrees of each other. It will be extremely unlikely for that to happen. If it does, MCAS will kick in for one cycle and attempt to pitch down for 9 seconds. An interruption by the pilot pressing the thumb switch in the opposite direction (opposite requirement not confirmed but assumed) then MCAS will stop commanding. If the AoA doesn't get out of the trigger range, it will still be the same event so it will not activate again.

FWIW, I very much agree with what Rheinwaldner is writing above.
There can be plenty of smoke and mirrors in this thread, and looks like some people have taken as their day job to post comments that try to deflect what really happened here. What's the goal, the create an impression that "most" posters think in some way? You have to wonder what makes people want to do that.
At the end of the day, no matter what the training situation is in the world, the stats for one aircraft model are way off from others, and not in a good way. Yes, the flights (probably) could have been saved by crew that acted in a very specific way. How foreseeable was that at the time, however? Even on this forum we're gone from the "but maintenance" to "just cut it off" to "obviously you should have adjusted first before cutting off" to "too much speed, they should have paid more attention to speed" and even the latest "don't raise flaps". What's common to these is that the posters -- months after the incident -- believe that crew should have followed a *particular* course of action among a set of many and raise that as a reason why it is a crew fault.
What seems to be happening here is that the poster crowd is trying to find a fault by the pilots. And it is easy. Curiously, very little attention is paid to the IMHO big mistakes in aircraft design, certification, and training requirements. A feature that points nose down in a critical phase of flight and no redundant design? A million things are thrown to the pilots in that same critical phase of flight and you're expected to figure which problem you have and react in seconds, and *no training*? Or else, the wrath of the a.net fanboys is upon you. Come on!
Plenty of blame to go around. But, I'd rather be a Boeing engineer or manager with guilt but with commitment that I will do better, than an investment banker posting in a.net or CEO trying to explain why nothing was wrong and there's nothing to fix. While at the same time fixing things! And we all should be thankful that we're not one of the 350 people dead as a result of all these mistakes.
Like Rheinwaldner said, take it like an adult and get on to fix your mess. Accidents are not 100.000000% preventable but when something happens, lets fix it and make sure it never happens again. And that responsibility lies on multiple shoulders. Pointing fingers to other guys does not help the process. At all.
Yes but ignoring the issues that have also become apparent in training are not helpful for safety either as many are trying to do.
Yes the stats are way off for the MAX and Boeing really screwed up the design - but it sure did uncover some training deficiencies as well. Are you honestly saying that Pilots shouldn't be required at least as a minimum to know how to control there airspeed manually? Just doing that would probably have resulted in an successful flight for ET.
ET had 50% of the Fatal Accidents in the last ten years with Pilot error at least a contributing factor. I am referring to AF447, Colgan 3407, ET409 and ET302.
They have .5% of the Worldwide fleet with 50% of the incidents - that's 100X the Worldwide average - there's some stats for you - but no the Ethiopian CEO says the pilots followed "all procedures" which is blatantly obvious from the Preliminary report they did not. They blamed ET409 on lightning. If you read the ET409 Final report it's quite obvious that the Pilot's manual flying skills were decidedly sub-par.
ET302 and ET409 Pilots went through 737 NG type training at about the same time.
I have no doubt that ET has great training system to teach Pilots how to use the Automated systems - but with 50% of the fatals in the last 10 years while manually flying ET training does not look so good.
Just to reaffirm - It's Boeing's fault that these incidents happened - but ET302 at least with the procedures they were required to know (and if ET actually informed them of the MCAS procedures) as part of there licensing should have saved the flight.
Also just to reaffirm my stance - this is not just a third world problem - as evidenced by the AF and Colgan incidents - as well as the many examples pilots have posted on these forums as well as others of basic procedures that are just no longer being taught and a general lack of knowledge on Airplane systems that newer pilots have worldwide.
The training system has gotten way too complacent and lax and needs improvement. With sufficient training, design and oversight it is conceivable that the existing low fatality rates grow even smaller - but you have to improve all three areas - design, oversight and training.
Still in the smoke and mirror business?
How about mandatory training for Boeing engineers that work safety relevant work on airplanes? How about a ban at Boeing for money managers to overrule engineers in safety critical cases? How about Boeing not ambushing pilots with Boeing made dangerous emergencies? How about Boeing not producing frames that do its best to kill crew and passengers? How about Boeing promoting pilot training instead of sabotaging it?
These two accident are the result of Boeing's negligent design resulting from Boeing's greed.

Because none of the simulations I've seen posted have attempted to simulate recovery starting from the beginning of the MCAS runaway. If you know of one, then I'd like you to point me to it since you are using them as part of your argument that they "just managed to avoid crash." That is only relevant if they are simulating starting from the point of failure.
What's the point? None of the simulations have been on true MCAS representative simulators. Even the Boeing simulator is claimed not to accurately reflect actual manual trim loads.

Yes I'm sure Boeing designed a plane on purpose to crash as that does such good things for it's bottom line. All designs are a compromise between safety, efficiency and cost and sometimes engineers make mistakes based on bad assumptions that pilots are able to handle the situations they supposedly are trained for.

I call it smoke and mirrors, because your calls for training start at the wrong end. Training at Boeing is needed for how to design save frames. It will help pilots if they are not supposed to fly death traps.
In regards to training for pilots flying Boeing frames, you also start at the wrong end. Training for pilots flying an manufacturers frames are based on the manufacturers recommendation. If the manufacturer recommends minimal training and sabotages the possibility that pilots are trained on all the peculiarities of said manufacturers frames, you again have to start with the manufacturer.

As far as we know, the NG simulators are accurately representing manual trim loads of an NG. Boeing's statement, and subsequently released update, is specific to MAX simulators. Unless the manual trim is radically different between MAX and NG, and there is no reason they are different, then the simulations performed in NG simulators should be a reasonably accurate representation of a MAX's manual trim system.
TL;DR… there's no reason to believe an NG sim is not accurately representing the manual trim wheel system in a MAX.

He has a bit over a hundred hours on a Cessna if I recall correctly. And he has done stall recovery training on it so he knows better than everyone, whether it be commercial pilots, industry experts, analysts, foreign regulators etc. If you jump on the band wagon of trying to pin the MAX crashes on third world pilots he will give you a digital pat on the back/wank under the table.
U.S. Federal Aviation Administration (FAA) representatives told members of the United Nations’ aviation agency they expect an ungrounding of Boeing Co’s 737 MAX jets in the United States as early as late June, three people familiar with Thursday’s briefing said, though there is no firm timetable for the move.

The grounding covers much more claimants than the airlines so biting the bullet for the penalty on increased training for the initial users should be much less expensive that a continued grounding, based on the time so far, we may already be past the cross over point.

No - my point is even with 120 hours in a Cessna that is nowhere near what it takes to be qualified to fly a 737 in commercial service - and the ET pilots had barely more than I have and in that time apparently they mastered instrument flying, night flying and the commercial rating as well and were put in the cockpit of a 737.
And as I have said many times it's not just the third world - it's everywhere - due to automation pilots have lost stick and rudder skills - which you will find tons of examples of on the net of pilots admitting that if you look.

Compensation is nothing compared to Chinese never letting MAX to fly. Half of the world's population live in that area. Canada is another issue after the attack on Bombardier. Very difficult to fly to/from Alaska without using Canadian air space. Never let someone to grab your balls. It hurts.

If you look maybe you would realize that:
1) Not all training is the same. There is a difference between getting a PPL as a hobby and training programs which are geared towards pilots who want to fly commercially (and don't equate your apparent lack of being qualified to fly a 737 in commercial service to every other pilot out there. That's your problem not theirs)
2) If not having the almighty 1500 hours flying a crop duster was the end-all there would be crashes weekly in Europe and Asia, but thousands of cadet pilots safely fly commercial aircraft everyday in all sorts of weather conditions to all types of airports
And spare me the bullshit about how you're concerned about ''worldwide lack of training''. You jumped into this topic trying to pin ET302 on the first officer for no other reason other than he didn't follow the North American path to being a pilot. Plenty of screw ups by 1500+ sky gods during your time on A.net (some of epic proportions) and yet no endless crusade about lack of training/questioning of qualification. Boeing decides to put profit above safety in their attempts to challenge the A320neo, gets grounded worldwide when things go sideways and that is when you decide to have your epiphany on worldwide training standards?

But out of natural curiosity, I would like to know the specifics of how the MAX differs from the NG in terms of longitudinal stability. Obviously, the larger more forward engines being the driving factor. What is the stall angle of the MAX versus the NG? What was the critical AOA that triggered MCAS? What did the stability curve look like at that angle? For MCAS 2.0, what are the limits on the angle of the stab that it can operate within?
Also I'd like an explanation from Boeing how they missed it. In the design of MCAS, presumably several people chose and checked the parameters, like going on for 9 seconds and turning off for 5 seconds. How did they miss limiting how many repetitions, or limiting the range of the stab to not operate in the nose down range where it wasn't needed to begin with? They limited it to not work with the flaps down, so obviously there were a lot of conscious decisions being made as to the limits of MCAS.
How did they miss the obvious? Boeing has to explain and account for an inexcusable void in what should be a foolproof in house design process.
They didn't miss it, they made the very bad assumption that an MCAS failure would be recognized as a runaway stabilizer and easily corrected by applying the runaway stabilizer NNC. Having it not work with flaps deployed wasn't some safety thing. That parameter existing leads to the conclusion that with flaps deployed, the aerodynamics of the wing are changed to the point where the engine nacelles no longer provide the additional nose up pitch (or at least not enough to have an effect on the weight of the control column).
Some of the other items you ask for are probably confidential. The stall angle varies with airspeed and altitude. I don't think it would be that different between MAX and NG since they have the same wing. MCAS was added to make it require more force on the column to reach the stall angle in certain situations since the lift provided by the nacelles made it the force required to pitch up further "lighter" on the MAX than the NG in certain situations.
As far as I've seen, MCAS 2.0 still has the same trim change rate and the same 2.5 degrees maximum trim change per cycle. However, it will only perform one cycle per "event." It will only be able to erroneously activate if BOTH AoA sensors fail and indicate false nose up attitude AND they both fail within 5.5 degrees of each other. It will be extremely unlikely for that to happen. If it does, MCAS will kick in for one cycle and attempt to pitch down for 9 seconds. An interruption by the pilot pressing the thumb switch in the opposite direction (opposite requirement not confirmed but assumed) then MCAS will stop commanding. If the AoA doesn't get out of the trigger range, it will still be the same event so it will not activate again.

So how did the ET training system work out for the ET pilots then? How many procedures did they miss? They did not follow all procedures like the ET CEO keeps insisting. However I will give the ET pilots a break as I believe that ET may never have informed them of the proper MCAS procedures - that makes a lot more sense than believing Professional Pilots who were given a valid procedure (you can see the Procedure the ET Pilots were given in the back of the Preliminary report) failed to follow it. Either their training was terrible or training failed them by never giving them the proper procedures in the first place..
Thousands of cadet pilots fly thousands of commercial flights successfully daily as the Autopilot is doing it for them. As long as it keeps working = no crashes
Almost all the fatal accidents in the last ten years are due to a lack of hand flying skills when the automation screws up. AF447, Colgan 3407, Et409, , Asiana 214, and the SkyDubai Moscow crash - all assuming the planes would do it for them and lacking the hand flying skills or confidence to successfully fly the airplanes manually.

The Pilots themselves don't agree with you, the airlines don't agree with you, every safety authority around the globe doesn't agree with you. Failures like MCAS are a big deal.

If you look maybe you would realize that:
1) Not all training is the same. There is a difference between getting a PPL as a hobby and training programs which are geared towards pilots who want to fly commercially (and don't equate your apparent lack of being qualified to fly a 737 in commercial service to every other pilot out there. That's your problem not theirs)
2) If not having the almighty 1500 hours flying a crop duster was the end-all there would be crashes weekly in Europe and Asia, but thousands of cadet pilots safely fly commercial aircraft everyday in all sorts of weather conditions to all types of airports
And spare me the bullshit about how you're concerned about ''worldwide lack of training''. You jumped into this topic trying to pin ET302 on the first officer for no other reason other than he didn't follow the North American path to being a pilot. Plenty of screw ups by 1500+ sky gods during your time on A.net (some of epic proportions) and yet no endless crusade about lack of training/questioning of qualification. Boeing decides to put profit above safety in their attempts to challenge the A320neo, gets grounded worldwide when things go sideways and that is when you decide to have your epiphany on worldwide training standards?
So how did the ET training system work out for the ET pilots then? How many procedures did they miss? They did not follow all procedures like the ET CEO keeps insisting. However I will give the ET pilots a break as I believe that ET may never have informed them of the proper MCAS procedures - that makes a lot more sense than believing Professional Pilots who were given a valid procedure (you can see the Procedure the ET Pilots were given in the back of the Preliminary report) failed to follow it. Either their training was terrible or training failed them by never giving them the proper procedures in the first place..
ET training system would've served them a lot better if Boeing didn't lie to them when selling them the MAX saying "90 minutes on the iPad will have you completely ready to handle the aircraft. Certainly no need to train your crews from the get go to the same level of proficiency they display on the rest of your fleet. It's true that the MAX isn't exactly a NG but we decided to cut a few corners and hide some critical changes to the aircraft so as to avoid paying the $1 million per plane to Norwegian, Southwest etcThousands of cadet pilots fly thousands of commercial flights successfully daily as the Autopilot is doing it for them. As long as it keeps working = no crashes
So what you're saying is those who got to 1500 hours flying a Cessna around a podunk town fly from origin to destination completely manually, no autopilot, no autothrottle, manual trimming? So they avoid RVSM airspace, fly only in VFR conditions?Almost all the fatal accidents in the last ten years are due to a lack of hand flying skills when the automation screws up. AF447, Colgan 3407, Et409, , Asiana 214, and the SkyDubai Moscow crash - all assuming the planes would do it for them and lacking the hand flying skills or confidence to successfully fly the airplanes manually.
I fixed you're mistake by taking ET302 off since that one goes straight to Boeing. And once again it has absolutely jack to do with flight hours. And anyone read this thread from the beginning knows that is what is behind your ever stupid "global training problem''. You jumped in with 1500 hours to fly a plane with the only reason it being required is because that's how we do it.

You obviously are not that familiar with ET302. The unreliable airspeed procedure they failed to execute is not unique to the MAX. Autothrottle is not unique to the MAX and failure to properly follow the MCAS procedure is on ET as well.
Hours flying manually certainly helps so you have the experience when the nannies try to kill you and you have to turn them off.
If you don't think that ET might have a training problem and lack of time flying manually look at the final for ET409 whose Pilot went through ET initial type training at about the same time as the pilot from ET 302.

But out of natural curiosity, I would like to know the specifics of how the MAX differs from the NG in terms of longitudinal stability. Obviously, the larger more forward engines being the driving factor. What is the stall angle of the MAX versus the NG? What was the critical AOA that triggered MCAS? What did the stability curve look like at that angle? For MCAS 2.0, what are the limits on the angle of the stab that it can operate within?
Also I'd like an explanation from Boeing how they missed it. In the design of MCAS, presumably several people chose and checked the parameters, like going on for 9 seconds and turning off for 5 seconds. How did they miss limiting how many repetitions, or limiting the range of the stab to not operate in the nose down range where it wasn't needed to begin with? They limited it to not work with the flaps down, so obviously there were a lot of conscious decisions being made as to the limits of MCAS.
How did they miss the obvious? Boeing has to explain and account for an inexcusable void in what should be a foolproof in house design process.
They didn't miss it, they made the very bad assumption that an MCAS failure would be recognized as a runaway stabilizer and easily corrected by applying the runaway stabilizer NNC. Having it not work with flaps deployed wasn't some safety thing. That parameter existing leads to the conclusion that with flaps deployed, the aerodynamics of the wing are changed to the point where the engine nacelles no longer provide the additional nose up pitch (or at least not enough to have an effect on the weight of the control column).
Some of the other items you ask for are probably confidential. The stall angle varies with airspeed and altitude. I don't think it would be that different between MAX and NG since they have the same wing. MCAS was added to make it require more force on the column to reach the stall angle in certain situations since the lift provided by the nacelles made it the force required to pitch up further "lighter" on the MAX than the NG in certain situations.
As far as I've seen, MCAS 2.0 still has the same trim change rate and the same 2.5 degrees maximum trim change per cycle. However, it will only perform one cycle per "event." It will only be able to erroneously activate if BOTH AoA sensors fail and indicate false nose up attitude AND they both fail within 5.5 degrees of each other. It will be extremely unlikely for that to happen. If it does, MCAS will kick in for one cycle and attempt to pitch down for 9 seconds. An interruption by the pilot pressing the thumb switch in the opposite direction (opposite requirement not confirmed but assumed) then MCAS will stop commanding. If the AoA doesn't get out of the trigger range, it will still be the same event so it will not activate again.
I think that a lot of the confidential stuff will be coming out in discovery.

It's becoming blindingly obvious that Pilots aren't as proficient in abnormal situations as presumed and that the FAA has to adjust it's certification standards which will cause Manufacturers to adjust there designs to this lower level of proficiency or training has to be increased..

Please stop with this garbage. The FAA created an independent group of experts that all had nothing to do with design or certification of the MAX to evaluate the fix and determine if the MAX will be safe. They have publicly stated that they won't lift the grounding without the blessing of that independent group.
