True, no emails, just literal theft of evidence. If the FAA says "this plane is safe now" people will fly on it, and airlines won't give them a choice, the number of people connected/informed enough to give a poo poo will be insignificant.

BIG HEADLINE posted:The last time I flew on a 737, before the MAX had been grounded, at least a dozen people were -ing about whether it was a MAX or not. It was a 737NG and they were visibly relieved when informed it wasn't a MAX. The 737Max story blew up (sorry) while my wife & I were in Florida. Our roundtrip was with Southwest. I remember stopping during our vacation to find a computer to look up a) whether or not we still had a return flight; and b) if that flight was on a 737Max. Because no loving way. Turned out we were on 737s both ways (eastern seaboard corridor) FuturePastNow posted:but would you fly on a 737-8200? Nice try, assholes. Arson Daily posted:Donald trump is president.

With the media attention on the MAX I'm pretty sure it's not going back in the air without being as safe as any other plane in commercial service, I wouldn't think twice about flying on one once the FAA and their European counterparts get done tearing it apart and certifying a fix. Thanks for the link, that's fuckin nuts

"737" is too generic for this thread. Southwest has flown 737s from every generation of the aircraft, and indeed has also flown most of the sub-types within generations too The OG adorable baby twinjets, the 737-100 and -200 The 737 Classic, including the -300, -400, and -500 variants The 737NG, including -600, -700, -800 and -900 variants The 737 MAX, including the MAX 7, MAX 8, MAX 9 and forthcoming MAX 10 You probably meant they were flying the 737NG on the eastern seaboard (as noted, going forwards they're probably going to dump the MAX name and just call them the 737-8200 etc) Sagebrush fucked around with this message at 05:50 on Jan 20, 2020 |

bull3964 posted:The situation is sort of unprecedented. The airlines need these planes. People likely aren't going to want to fly on these planes. Airbus really doesn't have capacity to replace all of them anytime soon nor do I think the economics work out that the airlines can go that direction anyways. Worse: some subcontractors who work for both Airbus and Boeing are in financial difficulties due to the MAX program being halted, and if they go bankrupt it will disrupt Airbus' supply chain. The situation is so that each of the Big Two can afford their rival to stay relatively healthy. They certainly each want to see the other's market share fall, but not too fast or it bites them too.

Jesus christ, every day there is new info about Boeing that is worse than the last day's. It's starting to feel like WeWork at this point. Today it seems lovely sensors were responsible for a crash in 2009 and Boeing has been covering this up. This was also their first lovely design that relied on a single sensor, which got carried over to the MAX. The failure to really acknowledge responsibility for the 2009 crash led directly to the terrible design of the MAX with the same failing sensors. https://www.nytimes.com/2020/01/20/business/boeing-737-accidents.html I wouldn't trust these idiots to develop a web site for a mexican restaurant, the fact that they are trying to fix every awful design decision in software is just stupid.

This is like babby’s first programming mistake here: quote:The 737 NG has two parallel sets of computers and sensors, one on the left side of the plane and one on the right. Most of the time, only one set is in control. Should I even call that a “mistake”? It’s an intentional decision. They knew it was the easy and inferior solution to “which input should the autothrottle use?”. They just didn’t think it would bite them. They were almost right. Even when their software killed, almost no one knew about it and they never would have had Boeing not killed scores more with MCAS.

unfortunately the LEAP-1B has a 6" bigger fan diameter than the V2500 that was used on the MD-90, but i guess they did put a 12" diameter propfan on the back of a MD-80 so it's possible.

So am I hearing this right that Boeing wants to software fix *everything*? Because tearing out MCAS would mean type certificate kerfluffle, and hardware is expensive? Because if so, they've learned nothing

Even if the answer is "turn it all off" that means the pilots didn't follow procedure and are technically were in the wrong.... ok I used the google cache trick to get the article: quote:As the plane dipped to 1,000 feet, the pilots had not yet completed their landing checklist. Strict adherence to airline procedure would have meant circling around for another try, but violations were commonplace at the busy runway, investigators later determined. Normalization of deviance is a good thing to focus on, but they applied TOGA power at 450 ft AGL and still crashed? drat.

they applied TOGA power significantly below 450 feet AGL. 450 is where the stick shaker activated, and the captain applied power 9 seconds after that. so they were probably a lot lower when power was applied.

hobbesmaster posted:Normalization of deviance is a good thing to focus on, but they applied TOGA power at 450 ft AGL and still crashed? drat. It could just be bad writing but the article doesn't say he applied TOGA, just that he pushed the levers up. The fact that they came back to idle immediately after would imply he bumped in enough to try and get it back on speed without realizing the A/T was misbehaving. They didn't go to TOGA power until 9 sec. after the shaker went off. This crash reads very similar to Asiana in SFO. 3 crew members on the flight deck, not monitoring the automation and assuming A/T will keep it on speed, not recovering from an impending stall correctly. Anyone who flies an automated plane should know the answer to fixing a mistake in automation is to remove it from the equation.

I’m likely wrong but isn’t TOGA in some airframes a command rather than physically moving the throttles to the power setting?

bloops posted:I’m likely wrong but isn’t TOGA in some airframes a command rather than physically moving the throttles to the power setting? In most airliners with auto throttles one of the things TOGA does is command the throttles to go around thrust. If the auto throttles are inop, not engaged, or overridden by the pilot, they will have to be advanced manually. On the 737 there are two settings of go around thrust. Pushing TOGA once gives enough thrust to transition to a healthy, but not excessive, climb rate. Pushing TOGA again sets max thrust which feels a bit like being strapped to a rocket if you're not prepared for it.

If it's not a piston prop, it's probably not physically moving a throttle.

It’s so good to know that the professionals feel the same distaste for the CRJ-200 that I do. Most of my travel up through college was flying out of Albuquerque, and if it wasn’t somewhere Southwest flew, I had altogether too high a chance of spending some quality time in the back of a CRJ-200 en route to Denver, Phoenix, or Salt Lake (whose regional jet terminal remains my mental picture of Hell). The fact that the window belt never got moved when the floor did during the conversion from the biz jet still amazes me. How do you not figure that one out?
