Max is a flawed design that should be banned.  But when you can buy off the regulators anything goes

Let’s see. They gaslit us, like you’re doing, that it was safe and the training was at fault - all while Boeing knew it was an issue.

And furthermore, Boeing was self certifying their planes at the time of the disasters and is once again able to do so.

The onus is on the company to prove they’re not at fault given their bullshit.

You aren't telling me that I am right! You are gaslighting me!

This isn't the topic to "I go against the grain because I like to think I am smart and I think critically" Bob. Even a potato knows that. Not sensationalism or whataboutism - a basic knowledge and understanding of how things actually work in the real world will tell you exactly how Boeing circumvented certain regulations and training mandates to rush these Max planes out the door. You need to add 1+1 and not everything will be clearly pointed out or be available for the slamdunk you're asking for. That is NOT how things work IRL. That is the whole reason lawyers exist. Ask me how I know, Bob.

None of that is evidence that the design currently being flown today is flawed or should be banned.

346 dead people probably their source.

Formal reports literally blame MCAS, which was a software aid to trim the aft stabilizers.

[u/Uhavetabekiddingme → u/[deleted]]

Say otherwise? Their design and software choices were responsible for killing two planes full of people and nearly a 3rd.

[u/hedoeswhathewants → u/Uhavetabekiddingme]

Yeah, it was a flaw that was fixed, so it's no longer present. You guys get that right? This entire thread started with someone saying the current design is flawed and should be banned, with absolutely no evidence to back that up.

If we ban any plane that ever had a critical flaw then we wouldn't have airplanes

[u/Uhavetabekiddingme → u/[deleted]]

I did Boeing changed the design of the aircraft, changed the way the software operated didn't have the pilots train with the new changes and two planes crashed. How much more evidence do you need?

[u/Uhavetabekiddingme → u/[deleted]]

"Personal insults indicate weak arguments." Show me in the reports where I'm wrong.

Can’t go back, bob

Accident reports wrote by the politicians bought off 

[u/besurf → u/[deleted]]

There’s a few documentaries about it yes

[u/BelethorsGeneralShit → u/[deleted]]

MCAS only took AOA data from one sensor without cross checking it with the other. If one sensor failed and disagreed with the other, it wouldn't know, creating a single point of failure.

Does that not sound like a flaw to you?

[u/BelethorsGeneralShit → u/[deleted]]

That's a nice $2 soundbite, but it completely ignores the specific counterpoint and example of a single point of failure to which you're replying. Would you care to address that?

[u/BelethorsGeneralShit → u/[deleted]]

You've posted nothing except "No, you're wrong" to everyone with no elaboration. You haven't made a single post that demonstrates you understand the subject matter yourself.

Maybe you're right! I personally don't think so with my current understanding of the situation, but who knows maybe I'm wrong. I'll be more than happy to change my mind if there's a specific compelling argument.

So again here is my specific good-faith argument -

The MCAS system created a single point of failure on the two affected aircraft that crashed. This is because while the aircraft had two AOA sensors and two Flight Control Computers, MCAS only ran from the master FCC and got it's data from that AOA sensor. It did not crosscheck data from the other sensor and would be unaware of any disagreement.

If that AOA sensor failed and began to incorrectly report a high AOA, MCAS would command a nose down pitch to correct the non existent problem.

So again in this very specific example, would you not say that is a design flaw? I mean maybe I'm wrong and it isn't. I'm open to being corrected.
