On the other hand, an indicator that one or both sensors are wrong is quite important when they are used by a system with authority to alter the flight of the plane.
I find it hysterical that the Wikipedia article has to go out of it's way in the summary section to point out that he cannot actually be the Zodiac Killer.
Unfortunately, the actual strategy is to invent a new name. Announce it like it's a buyout rather than a rebranding. Put stickers with the new name at the top of all of the old documents. Raise prices 5% and BINGO!
Under no circumstances improve any product or service. Lather, rinse, repeat.
MCAS wasn't documented to exist at all. It's behavior looked a bit like runaway trim, and there was a checklist for that. Some pilots may have tried it since it's better than crashing.
There is part of the issue. The systems and procedures we are talking about are type specific. That is, particular to these aircraft. An Airbus or other Boeing planes for that matter have different systems and procedures. A general commercial pilot's training for a specific model or group of similar models is known as type certification.
MCAS was meant to make the 737 MAX behave enough like the old model that it would be considered the same type. When that decision was made, MCAS wasn't documented.
The misconduct centered around suppression of research that had "unfortunate conclusions", and so tends to indicate that MONSANTO believes it causes cancer.
That kind of testimony to a layman jury seems relevant enough. Had it been a mile long list of tickets for jaywalking and moving violations, not so much.
How much would we need to pay you to endure years of treatments almost as toxic as the disease with no certainty that you won't die of the disease anyway, or ironically, die of the treatment for the disease? All the whiole, massive medical bills come in and you rarely feel good enough that you can do anything for 8 hours, much less work?
And, by the way, you have about a 50-50 shot at living 10 years from today.
Now, ask how many bazillion dollars Monsanto made by gambling with YOUR life.
The class of problem, "runaway trim" can be caused by a few different systems malfunctioning. Most of those systems also exist on the old 737, but MCAS is new to the MAX and behaves a little differently, though if you figure that out, the remedial action is the same.
It seems that part of the problem is that the system effectively wrestles with the pilot over who is in charge of the trim. MCAS trims the nose down, pilot re-trims it up, 5 seconds later MCAS trims it back down, loop forever until pilot figures it out and disables MCAS or the plane crashes.
It really is both. Initially, Boeing did not document the existence of MCAS. Some pilots may have stumbled over it's existence and applied a checklist for similar failures in documented systems.
Later, Boeing was required to document the existence of MCAS and state clearly that the runaway trim checklist should be followed when it malfunctions. Apparently not all pilots got that memo (so also a training problem).
They already have the service documentation, specs, etc for internal use. They are even already on internal access websites. It wouldn't really be a big deal to make them available. They certainly don't HAVE to make the devices use cryptography techniques so that they refuse to accept already existent 3rd party replacement parts (Apple, John Deere and others do this). They don't have to use non-standard screws and then add glue in an effort to make repairs harder. Those things that they don't have to do actually cost them extra money to develop and implement.
And the ultimate trump card, the larger society and it's government are not obligated to grant them a charter to exist as a legal entity at all. Corporations are entirely a legal fiction whose charter is GRANTED by government. They are not living beings, They do not have natural rights. There is no obligation to allow them to abuse the DMCA to prevent others from making replacement parts or to prevent repair shops from taking 2 broken devices to make one that works.
It is a bit "interesting" when unapologetic capitalists fight so hard against property rights for everyone else. Almost as if they don't really believe in capitalism so much as they believe in I got mine, screw you!
Door openers are RF. Universal as in in it's day it would open any garage door. These days it is restricted to older doors.
Your car's opener has a receiver that it uses to learn your door's code from your existing remote. Anyone else can put a receiver in range of your garage door and learn the code as well by listening when you open it..
In fact, there are people who modify their diesel trucks to spew large clouds of soot. In doing so, they spend money, reduce engine power, and reduce fuel milage. Apparently they DO want pollution. I have no idea why. Search on "rolling coal".
A subset of those people like to crowd around Tesla superchargers with a stated goal of blocking access to the charger.

It's worse. The features were available, just turned off unless you coughed up more money for them.
They literally nickel and dimed hundreds of people to death.
It's not unlike what I had in the first grade where we had images of concrete objects (sticks, oranges, etc) with the mumbers underneath.
MCAS doesn't shut down with the autopilot. If the pilot manually adjusts the trim, it disengages for 5 seconds, then goes back into action.
That makes a lot of sense. Easy to access legitimately, hard to access nefariously.

MCAS only operates under some conditions, leading to what may appear to be an intermittant condition rather than an ongoing runaway trim.
You broke it. MCAS behaved a bit differently.

These are the people who choose between a broken leg and a kick in the nuts.
In many cases, the magic 8-ball can make better decisions than politicians.
That's how it should be, but that's not the world the plaintiff lives in.

HArd time for the execs isn't currently on the table. Actual losses, mental anguish, and punative damages are the only options on the table here.
Don't forget extensive legal fees, experts, research, the lawfirm taking significant risks of time and money for all of that, etc.

But the point is, the GPs last paragraph was factual, not bigoted and misguided. Do the search, marvel at the people reveling in rolling coal.
