Re: Ethiopian Airlines Boeing 737 pilots 'could not stop nosedive'
#72I’d love to see those people who accused the airline and crew of being incompetent to apologize in the light of these reports. It was shameful to see Boeing actively encouraging that narrative behind the scenes. Especially considering it plays on racist stereotypes equating „Africa“ with bad training/bad safety record/…. The idea of „dingy third world airline“ was ridiculous on its face, considering how bad a fit fly…
I'm really surprised they didn't go ahead and blame the pilot's "ethnic culture" like the did with Asiana 214 [1]
Re: Ethiopian Airlines Boeing 737 pilots 'could not stop nosedive'
#73Will be interesting to see the details when the report is actually public. It does sound like the scenario that Mentourpilot explored in the simulator is close to what happened, namely: Bad AoA probe causes MCAS to trim down, and also to indicate IAS disagree. Pilots increase throttle as per non-normal checklist to reduce the risk of stalling due to unreliable airspeed. Pilots disable electric stabilizer trim, as per…
The official report will make for interesting reading. The speculation over the last few days is starting to fill in some questions I've had:
- Why didn't the pilots identify the issue as MCAS malfunction and follow the guidence?
They did and it didn't work for some reason. Possibly because of the air loads on the stabilizer.
- Why did the AoA sensor on a new aircraft fail?
Suspected bird strike.

#74With such new evidence, how FAA which refused to ground the 737 Max should be allowed to walk away from all these for nothing?

Hard engineering problem - where do you open up the fuselage to get the people out? It's a tube so you can't weaken it. You also can't open a hole at the back and let them slide out backwards, you'd need a cylindrical tube in a tube which can then slide out. That's a HUGE amount of extra weight and complexity. Planes are so so much safer than cars. Before we parachute people out of passenger planes we should be eject…
Maybe just jettison wings+engines+cargo? Though I agree that broadly safety is solved. And obviously we must heavily reduce air travel to combat global warming.
The question then becomes are can a plane fly with each of those attached by structural bulkheads & explosive bolts.
The remaining ‘crew and passenger capsule’ would need to remain sealed.

Yep, the issues started way earlier than the software. In fact the software is at the very end of the chain here, unless you also want to insert "no training". It all started when they wanted those big engines crammed into an airframe not designed to hold them, so as to try to quickly catch up to shifting market demands being met by Airbus.
How can you say “no training” caused this second crash after reading the article? Did you read the article?
They said no such thing
Re: Ethiopian Airlines Boeing 737 pilots 'could not stop nosedive'
#77Every time I read about these plane accidents, I wonder why planes don't have any emergency features to save these people. Couldn't you build a plane that would eject the cabin as a parachute module or something. Yes, I'm sure this is naive, but why? Edit: My point is that almost anything is better than crashing down with the plane.

Rear exits aren't absolutely unheard of: the 727 and the DC-9 family had rear stair exits, and the 727 one was used in flight at least once (by 'DB Cooper' - probably not successfully though).
I don't fancy the chances of the crew getting the whole cabin of a 737 out of a single door, in flight, after fitting parachutes, but without parachute training, before hitting the ground, though. Even leaving aside the weight and bulk of the parachutes.
As you say, not a great idea.
Re: Ethiopian Airlines Boeing 737 pilots 'could not stop nosedive'
#78If this was indeed MCAS, it is my understanding they 'could have' stopped this by turning off power to the electronic stabilizer trim.
Per the friendly article, "Pilots "repeatedly" followed procedures recommended by Boeing before the crash, according to the first official report into the disaster."
Exactly.
I find it embarrassing for the society as whole how many people these days comment on articles or posts by just reading the title.

Can you imagine the scale of parachute that would be needed to safely bring an airliner cabin to earth? Could a parachute on that scale actually be made sufficiently strong (and light), and successfully deployed? I doubt it.
I want a wingsuit on my ticket. If I die at least I'll be superman-like for 30minutes

Since this video may not be coming back I'll post a sort of transcript from memory since I was lucky enough to get to watch it. I'll try and just describe what I saw and keep my commentary/speculation to a minimum - in . Bear in mind this is a non-pilot observer's take on it from flaky memory Was the video pulled? Who did that, and why?
He pulled it himself. https://twitter.com/MenTourPilot/status/1113723580284583936
His channel is worth following. He often posts insightful stuff related to incidents with 737s or just general information. He had a nice video about emergency procedures with a total engine failure in (probably) the same simulator just a few weeks ago.
