Clearly a much superior white american would have somehow landed a completely unflyable plane while singing the star spangled banner. there were five reported incidents among u.s. carriers and no losses (of course they probably bought the extra bells and whistles!)

Yeah, thanks for explaining this. None of the news articles I have seen have actulaly explained whether the pilots understood the problem and followed the proper procedures; this makes it much clearer.

Elon "Monkey Cheese" Musk is living proof that people often don't act rationally, and such concerns about liability aren't even on his radar (much like fire trucks and lane markings).

my bet on both of those videos is the car seeing something that looks like parallel lines and assuming they are lane markers. in the first video it seems to screw up its steering when the two white poles holding up the road sign are in full view, and although we don't see how the second car went into the ditch/moat, it sure does have nice straight parallel sides.

no it's not about race, it's just that non-white pilots are worse at flying. how could you possibly misconstrue this as racist.

It's always very hard to tell what's going on from a dashboard cam when a car is long traction. It looks a lot more extreme outside the car when you can see the rear end end swinging around or the front wheels pointed the wrong way and can hear the tires squalling. From this first person footage wherever the car seems to "steer" off the road and wiggle the steering left and right, I would assume that it has lost traction and that the wheels are just pointed one way while it slams the brakes way too hard to not lose its poo poo off of the road. It simply looked like it entered the turn too fast to have any hope of keeping traction to have the presence of any indecisive steering matter at all.

that tesla took an offramp at over 70 mph without braking of course it's going to fly off the road.

Boeing is responsible, but not because they charged extra for a lightbulb. The pilots were doomed with or without the lightbulb. The airlines did not err when they declined to purchase that package. The pilots did nothing wrong. It’s not possible to train for something you don’t know exists. Saying “MCAS is poorly documented” is a gross understatement. Parts of it are entirely undocumented and for other parts, the documents lie. Boeing said MCAS can command maximum downward trim of 0.6°. It turns out the real figure is 2.5°.

hobbesmaster posted:both crews followed boeing's procedures as published and displayed excellent airmanship. they were not "poorly trained" by any means and assuming they were is insultingly racist. thats not at all what I was getting at. i am going to need to unpack my understanding of the full background to explain: 1. facing the prospect of losing 737 sales to the A320neo (up-engined A320), boeing had a problem: they could not mount larger diameter engines to a 737 due to its low wing. the 737 is a 1960s airframe originally designed for narrow turbojets, and boeing had already pushed engine diameter about as far as it could go in the 1980s when converting it to turbofans. so, boeing initially planned to take the hit and design an all new airframe. 737 customers told boeing they’d just go buy airbuses instead. that led to 2. boeing came up with a flawed plan to push the envelope of what kind of modifications can be made to an airframe and its flight handling characteristics without making it unsafe. they wanted to sell airlines and the faa on the idea that, for type certification and training purposes, the 737max was just another 737. also it had to be a rush job. but, 3. boeing knew that moving the engine mount point way forward and up (to get enough ground clearance) was going to produce a strong nose-up torque, doing bad things to handling and stall risk at high AoA, making the plane potentially very dangerous. so, 4. they invented MCAS. it’s intended to automate the nose down control input required to recover the airplane from flight regimes that aren’t dangerous on other 737 models. they claimed that MCAS would only trigger in extreme circumstances, so pilots didn’t need much training for it and then, 5. by running so much of the type certification themselves they managed to fool themselves into thinking mcas was safe and working as planned so, 6. pilots round the world started flying the 737max without adequate training on mcas, its potential failure modes, emergency procedures, how to disable, etc. boeing claimed it was just another 737 after all, and the faa rubberstamped it, and they’re both trustworthy right? boeing even went so far as to sell a mcas related warning indicator as an extra cost option so how serious could it be? and last but not least, 7. they weren’t trustworthy. turns out there are some pretty awful design flaws in the mcas system so, far from believing the pilots were at fault or invoking racist stereotypes, i think that boeing and the faa have blood on their hands. the pilots were in effect poorly trained on the type, but not due to any failing on their part. sorry for my op compacting all that into a shitpost without nuance adequate to distinguish it from “lol third world pilots amirite???”. i believe these things are all true: 1. they weren’t trained adequately 2. it was in no way their fault, or related to where in the world they were from 3. they did the best they could given the resources they had 4. the primary cause of the accidents was bad automation, the role of training here is only that better training would’ve given them a better chance of surviving the murderous robot

ethiopian is the largest airline in africa and its pilots are as well trained as those of any other major flag carrier like british airways or lufthansa or whatever. there is no one specific cause of these crashes (and, indeed, there are dozens of different steps that would have prevented it had they not all stacked together) but ultimately it's another example of engineers ruining poo poo by not taking any human factors into account (the engineers may have been pushed to do this by dickless corporate bean-counters but they're still responsible)

like, example: the MCAS system can command the stabilizer to trim down by 2.5 degrees every 15 seconds. (10 seconds to trim down, then a 5 second wait before trying again). if MCAS is faulty, you have to turn off the electric trim motors because otherwise MCAS will keep pushing the trim down like that every 15 seconds continuously. the stabilizer can rotate for trim through a range of 17.1 degrees. when the motors are off, trim is effected through the manual wheels, which are the black and white wheels on the outside here: in manual mode, it takes 250 full rotations of the wheel to move from full up to full down trim (17.1 degrees). that is, one rotation of the wheel corresponds to 0.069 (nice) degrees of rotation. so, to manually recover from MCAS' trim command you would have to spin the wheel 40 times. to match the nose-down commands being generated by the computer you'd have to spin the wheel at 240rpm -- four full revolutions per second. do you think you could do that? how about with one hand, while trying to hold the yoke back with the other? how about when the wheel is actively fighting you, because you're trying to push a 15-meter-wide airfoil against a 300mph slipstream? like, as a human factors question, you don't even really need a professional ergonomist to tell you that it's an unreasonable demand, right? well, someone should have told that to boeing's engineers Sagebrush fucked around with this message at 04:30 on Apr 11, 2019 |
