JAKARTA/SINGAPORE/PARIS (Reuters) - The pilots of a doomed Lion Air Boeing 737 MAX scoured a handbook as they struggled to understand why the jet was lurching downwards, but ran out of time before it hit the water, three people with knowledge of the cockpit voice recorder contents said
The captain asked the first officer to check the quick reference handbook, which contains checklists for abnormal events, the first source said.
For the next nine minutes, the jet warned pilots it was in a stall and pushed the nose down in response, the report showed. A stall is when the airflow over a plane’s wings is too weak to generate lift and keep it flying.
The captain fought to climb, but the computer, still incorrectly sensing a stall, continued to push the nose down using the plane’s trim system. Normally, trim adjusts an aircraft’s control surfaces to ensure it flies straight and level.
“They didn’t seem to know the trim was moving down,” the third source said. “They thought only about airspeed and altitude. That was the only thing they talked about.”

“The manufacturer has said there is a documented procedure to handle the situation.”
Too bad it wasn’t in the quick reference book.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Look in the wreckage for a “How To Fly A Huge Plane For Dummies” book.
And too bad it wasn't written in Indonesian...or whatever language they speak in Indonesia.
Fake News.He had 200 hours in type, not total time. Everyone has to start somewhere. I believe the First Officer had in the neighborhood of 5000 hrs.
“I’m gonna wait for a final report issued by a body that has no reason to lie”
I agree with your post.
Seems like if there is a peculiar behavior inherent in all 737 MAX airplanes then the thousands of airline and test pilots would have warned about it.
Unskilled pilots or a component failure seem to be the most likely cause of the crashes. But a component failure on two crashes within a few month in a 3rd world country. Ok, throw in poor maintenance.
How much muscle power does it take to pull back the yoke if the trim tab is set to nose down? Seems to me my arms would NEVER get tired.
Your first homework assignment is to get a map and figure out if Indonesia and Ethiopia is the same place. Then look at the dateline on the story posted here, and figure out which of the Boeing failures is being discussed.
The pilots of the Lion air flight had approximately 6000 and 5000 hours of flight time respectively.
Is this plane so inherently unstable that it has to have software to keep it flying? And the system is not documented to pilots? And the procedure to shut it down is not available in the quick ref manual?
So much wrong here. Really loved Boeing and its history, but this really sucks.
From the article:
The flight data recorder shows the final control column inputs from the first officer were weaker than the ones made earlier by the captain.
I wonder if the pilot had enough practice disconnecting the trim inputs ? Some sort of drill , either real world or simulator ?
“I believe the First Officer had in the neighborhood of 5000 hrs.”
Whatever it was it wasn’t enough.

It’s supposed to be “aviate, navigate, communicate”, not “bloviate, defecate, terminate”!
“How much muscle power does it take to pull back the yoke if the trim tab is set to nose down? Seems to me my arms would NEVER get tired.”
The aircraft apparently was in control, and it thought it was right. You can’t win that argument.
I've only had my jeep for two weeks and the electronics on the thing are incredible.
The biggest problem I have right now is with the keyless entry. I'm constantly getting out of the car with the key fob in my hand and forgetting to push the button to turn off the engine.........LOL!
If the failure of a single sensor can send the aircraft into a dive toward the ground, it is not "pilot error" if the unfortunate pilot is unable to deduce the cause and determine the solution in time. The problem is that the aircraft dove toward the ground.
It would have been great if these pilots had been better trained, or had better documentation. But the fact is the aircraft crashed itself, because it was getting erroneous sensor information, and the system was not designed well enough to prevent a fatal response by the flight control computer.
True.But there are several variables. Where will the lawsuits be filed? Very probably in the US...but possibly elsewhere.
One thing's for certain...regardless of who weak the case might be to support culpability for Boeing (as opposed to pilot error,poor maintenance,etc) you can be sure that a judge or jury that knows *nothing* about aircraft will find for the plaintiffs.
What does that mean? There is no yoke? You can't pull the nose up? SEL pilots want to know.
“What is the correct number then?”
More than what they had.
Next question.

Apparently not!
