Will the 'supposed flaw' also be ruled out in the other crash that happened shortly after takeoff and showed the same rapid changes in altitude?

Re: Bad day for Boeing
So now it seems Boeing had a fix for this that they were planning to roll out but it was delayed five to six weeks by the government shutdown.
The cause seems to be erroneous sensor data from a single sensor that detects the pitch of the airplane nose. The new software will change the system to rely on multiple sensor inputs rather than a single.

Boeing to Make Key Change in 737 MAX Cockpit Software
MAX software change marks shift for Boeing design of anti-stall system
https://www.wsj.com/articles/boeing-to- ... 1552413489When the plane was first designed, engineers determined that using a single sensor—measuring what is technically known as the angle of attack—would be simpler and was in line with the plane maker’s long-held philosophy to keep pilots at the center of cockpit control, a person familiar with the matter said.
That earlier design of the system, known as MCAS, has puzzled some pilots and safety experts, who wondered why the system didn’t rely on multiple feeds.
Mike Michaelis, chairman of the safety committee at American Airlines Group Inc.’s pilot union, welcomed news of the coming Boeing software fix. “That’s the way it should have been in the first place,” he said.

Fuck no. Care to get your shine box out and dust it off?
https://qz.com/1570266/ethiopian-airlin ... max-fixes/Straightforward safety upgrades to the jets’ software to fix the automated safety feature, were originally expected in January according to multiple reports. But they were delayed until April, the Wall Street Journal reported Feb. 10, because of “engineering challenges,” “differences of opinion” between federal and Boeing officials, and the 35-day government shutdown, during which “consideration of the fixes was suspended.”

Dehumanising the opposition is a basic aim of propaganda. Anyone not in lockstep with the talking points is an NPC, which is kind of ironic. I bet the right wing nuts getting rounded up with their arsenals and librul kill lists of politicians and reporters are steeped in this NPC shit.

Re: Bad day for Boeing
Isn't it one of the pilot unions saying the problem is with the training? There are no simulators for it, no required specialized training and the manual is shit. For the training they are just assuming if you can fly one of the other planes, you are qualified to fly this one.

Re: Bad day for Boeing
This guy's a pilot who does a podcast explaining all things commercial aviation. Apparently the 737 pilots switching to the max B weren't even told the system existed before the lionair crash.
Canada has now joined the rest of the world in grounding all of them, they cited new satellite data showing the ethiopia flight behaved just like the lionair flight.

Re: Bad day for Boeing
If it emerges both crashes were caused by something completely unrelated to the dive issue and to each other, grounding the planes while we find out would still be the right call. Naturally you're unable to reconsider your start conclusion though.

Re: Bad day for Boeing
Both fatal crashes showed the same oscillations and loss of vertical control, indicating repeated dives - which is what the MCAS system does when it thinks a stall is coming due to a faulty AOA sensor. Both sets of pilots reported control issues and requested a return before nose diving into the ground. Two pilots in the US it now emerges have also reported their max 8s abruptly nose diving for no discernible reason. After the lionair crash the FAA issued an emergency airworthiness directive highlighting the MCAS control issue, and Boeing announced it was working on a software fix.Biker wrote: ↑Wed Mar 13, 2019 8:03 pmMore news will be coming out within the next ten days so we'll see.

Re: Bad day for Boeing
Would you even notice the plane descending sharply as a passenger? I doubt it. The effect on a passenger would be less noticeable that turbulence, and who bothers reporting turbulence on a flight? It happens, you assume the guys up front know what they're doing.Biker wrote: ↑Wed Mar 13, 2019 8:23 pm I know your search engine doesnt tell you this, but do not dismiss the power of pilots unions. Somehow we are to believe, in a world of Twitter, FB, Instagram, and every other SM outlet there is, not a single passenger posted about taking an abrupt nose dive in flight. This is what we're to believe, right?
Why do you think these independent US pilots filed reports on the kamikaze problem?

Re: Bad day for Boeing
The Lionair and Ethopia flights repeatedly nosedived - something we know the MCAS system would do in response to a perceived approach to stalling - and did in fact kamikaze. The US pilots reported single abrupt dives which did not repeat after disabling the autopilot.Biker wrote: ↑Wed Mar 13, 2019 8:35 pmYoure saying they nose dived and kamikazed.

Seems rather unlikely based on the pilot not thinking to mention it when he told air control he had flight control problems and wanted to return.
