i just read part of the seattle times article which stated that the lion air crashed involved 21 mcas cycles of the computer pointing the nose down before the crash i kinda hate to get medieval, but the entire loving C suite of Boeing should be mandatory passengers for the test flights for the upcoming software fix for the max 8

Shear Modulus posted:what is an mcas cycle mcas is the new computer system that prevents tail strikes in the 737 max 8. it takes input from a single angle of attack sensor and will adjust the rear flaps to push the nose down to prevent a stall/tail strike. there’s an initialization bug in the software that will improperly reset sensor inputs if the mcas is overridden, and it keeps trying to push the nose down. I highly recommend reading any articles about the issue. https://jalopnik.com/recent-boeing-737-max-crashes-may-be-the-result-of-a-si-1833380459

Shear Modulus posted:what is an mcas cycle It means how many times the MCAS system on the Boeing 737-MAX8 kicked in and overruled the pilots, and thus proceeded to point the plane straight into the ground. 20 times the pilots fought the mcas system. The 21st time, the air ran out.

And it was published in 1996, so presumably the festivities have continued since then. H.P.

Shear Modulus posted:lol cool planes these days have all kinds of automated systems designed to address what happens if the flight computer thinks the pilot is flying the plane wrong. more and more often, they address it by just quietly adjusting the plane's flight path on their own, either giving no indication that they're doing so or barraging the pilot with a dozen confusing alerts all over the plane's nightmare of a UI usually, the plane manufacturer doesn't make similar allowances for the pilot to intervene if they think the computer is flying the plane wrong. the systems can easily override the pilot, since they're mostly there to guard against human error, but it's difficult for the human to override them in case of computer error it's not even close to the first time something along these general lines has happened, either. for example, here's one in 2008 where the pilots managed to avoid crashing. memory corruption led to one of the flight computers mistaking the altitude for the flight angle, deciding that the plane's nose was angled way too high, and "helpfully" trying to point the plane downward

it’s somewhat an apples to oranges comparison, but they’re still both fruit. you wind up with a bunch of armchair pilots (read: forums warriors) talking about how pilots don’t even do their job anymore and how it’s all handled by the computers and how back in my day we flew 15 miles uphill both ways, etc; however, a software/UI gently caress up is a software/UI gently caress up no matter how you want to frame it. with previous versions of the 737, if you pulled up on the stick it’d tell the computer to gently caress off and stop helping. for the max 8, they changed this behavior and didn’t really tell anyone about it. boeing went out of their way to black box everything about mcas and it turns out abstracting out something that points the nose down might not have been the smartest thing to do. that said, i’m confident that boeing’s internal investigation is going to leave no rock underturned and come to the conclusion that boeing did nothing wrong.

Critical control systems should use triple-redundant voting logic, it's pretty common in aviation. I'm trying to understand why the MCAS system was tied to a single sensor.

And they did this because when they changed the engine to increase range and fuel efficiency, it caused the plane to nose up. Rather than fix these aerodynamics, which would basically mean a new chassis, the opposite of their intent, they fixed it with software. Now the real crime is that the big red warning light for this issue which was known about was sold as an optional extra.

Shear Modulus posted:didnt they get around that by saying that the system was noncritical and they did that by lying about what it does, stating that could only make a small correction once instead of it being able to make a correction 2.5x larger multiple times. Also the level they rated it (hazardous vs. critical) still demands redundant sensors but it turns out if you're certifying yourself you can just ignore that too.

Dead Beef posted:lol the "AOA DISAGREE" warning is sold as an optional feature I've read that but what nothing I've read has stated is whether the pilot in knowing that has any other option but to fight the computer trying to crash the plane. My reading (admittedly poor sources) seem to indicate that even if the pilot had the warning they still can't do anything about it.

I've watched ID theft in action and it's a loving mess to sort out. Victims should immediately file a report with the FTC. Once you have an official report you'll have a little more power. Banks are more likely to block attempts to unfreeze accounts that have been reported to the FTC. The police can (or should) help you create a police report with all the relevant information (see link below) and then the police report itself can be added to the FTC report which will give you even more power. https://www.identitytheft.gov/ If you're having a problem with the police, print this out and give it to them: https://www.consumer.ftc.gov/sites/default/files/articles/pdf/pdf-0088-ftc-memo-law-enforcement.pdf Even still it's a nightmare to resolve
