This video explains really well.
I think Boeing is going to take a loss on this plane big time.
I posted it from Wimp.com, not Vox.
If the source is Vox, that’s on them and not me.
The explanation provided in the video seemed reasonable enough that I didn’t see problem with it.
The pilots may not have been able to disable the automatic software, because Boeing was trying to minimize pilot error.
I watched a very good video of an airline pilot analyzing the premliminary report. That 200 hour pilot did exactly the right thing. The problem was, he did it too late. By the time they implemented the correct procedure, the plane was at full throttle and moving around 500 mph, and the force on the horizontal stabilizer was so great that the manual trim controls could not be moved.
I'm confident a pilot facing the terror of his imminent death would have exerted every ounce of his strength to move those stabilizer trim wheel, but at the speed the plane was moving, and with the degree of up angle on the stabilizer, it was virtually impossible to move those trim wheels without dropping the nose, and they were simply too low to the ground to allow that.
They should have cut off the automatic stabilizer trim as soon as it started giving them troubles. They waited too long.
No one has done a better job than this guy on telling us about this crash.

They turned the MCAS system back on against the protocol and never flew the plane by hand. They tried, but the auto-throttle had the throttles firewalled and when they re-engaged the MCAS the plane flew into the ground near the speed of sound, far above the “never exceed speed”. The plane was doomed by bad piloting. Boeing is not blameless here but bad pilots flew the plane into the ground by violating directives.
It may be more technically correct, but it would have been better for him to provide a summary at the begininning and then go into technical details for those interested.
First thing I saw on the video was a big "VOX" logo right in the corner of the video. I shut it off and killed the link.
Vox is our enemy.
The pilots may not have been able to disable the automatic software, because Boeing was trying to minimize pilot error.
This is incorrect. There are two very big red switches prominently located right between the seats. Shut those off, and there will be no further automatic adjustments to the horizontal stabilizer.
What did you expect from VOX liars? They lie all the time. They are nothing but human garbage, and if they tell you anything, it has a 90% chance of being crap.
They also changed the shape of the nose as well. That with the engines makes it want to go nose up.
“The pilots may not have been able to disable the automatic software, because Boeing was trying to minimize pilot error.”
Only they did.
“but at the speed the plane was moving, and with the degree of up angle on the stabilizer”
Up angle? The MCAS moves the trim to a down stabilizer.
“I don’t understand why you would need an angle of attack sensor out side the cabin.”
It’s AOA to the apparent wind. Not angle of aircraft to the earth.
“The only way to stop if from controlling the plane was to cut power to the electric motors that run the trim. “
The yoke trim button over-rides MCAS.
“Why not let the nose rise and cause a stall warning if it needs to. Just put a blurb in the iPad training that the higher mount of the engines may cause the nose to rise more at full thrust.”
That was not why MCAS was installed. See my earlier post.
So Smith&Wilson should be responsible for incompetent firearms users?
Most third-world nations are serviced by some first world air carrier. When I would travel to Africa I would never fly on a national carrier. Would adjust my schedule if needed to get on a Brit Air flight.
But fly on whatever carrier you want.
ME? Emerites Air or Singapore Airlines excepted, of course. . .most all are British pilots.
Indeed. “Loss of situational awareness” is a real dangerous thing.
I would think that would be useless when you are traveling so fast. The wind wold be parallel to the direction the plane is moving.
IMHO The angle to the earth would be a better indicator of the flight path. - Tom.
Oh, and systems knowledge is essential- turn it off and if necessary pull the circuit-breaker (and know what other systems might be affected.
No simulation can justify 1 sensor as the only input to override pilot control.
This was criminal, no doubt in my mind...
Airworthiness certification for a plane without redundancy in a system is NOT about simulations.. the need for redundancy had been a requirement for civil aviation for a long long time... there was criminal activity involved in this plane getting certified for airworthiness with a model that had only input from one sensor allowing the override of pilot control..
There is no other way this happens unless you believe that all of Boeing and all of the FAA are innept.
You will find evidence that folks inside Boeing and the FAA warned that this was not acceptable I guarantee it.
Either folks in Boeing lied to the FAA that more than one sensor was used for override.. and the FAA didn’t verify. Or someone(s) in the FAA took a bribe or Boeing’s political connections forced an override of the FAA internal folks objecting.
This will have chronic capitalism at its core one way or another
Everyone misses the fact that Airbus and Boeing are making airplanes that they need to sell to third world countries with low time, inexperienced pilots.
This fact has now come up to bite Boeing in the ass. Airbus had their bite when a flight augered into the South Atlantic on the way to Paris years ago.
NOTHING can replace basic flying skills, learned,over time, on how †o manually fly an airplane without all of the autoflight features that exist on today’s airplanes.
Fly first world or risk your butt!
