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 planes 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 planes trim system. Normally, trim adjusts an aircrafts control surfaces to ensure it flies straight and level.
They didnt 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.

I don’t agree. I’d argue that many human error circumstances have been avoided. Modern aircraft fly themselves 99% of the time. The incident rate is very impressive compared to the past.
“Quick, quick! Google “how to avoid a plane crash”!”
“Yes, sir.”
Suggestion—
Stay off third world airlines. Governing authority is ineffective. Insist on either EASA or US (FAA) certification of training. Most third world crews have minimal experience and minimal training. Maintenance is unlikely to be any better unless outsourced to a first world regulated shop.
Been there, seen it.
This aircraft was crashed by the Maneuvering Characteristics Augmentation System (MCAS) system, which is active whether the autopilot is on or not.
In this case, the pilots were hand-flying the plane right into the water. They wanted to go up, the MCAS wanted to nose down. The MCAS won the fight before they were able to disable it.
Seattle Times reported yesterday that the MCAS delivered 4 times more down bubble that FAA approved.
Yeah I get it.
The new fobs are not really designed to go on a key ring. Just put it in your pocket or purse and leave it there. No need to ever touch it except to get it in the morning and put it away at night.
Ruh roh...
re:
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 cant win that argument.
The area under control of the Trim Stabilizer is a lot larger than the area for elevator control (from the pilot’s ‘stick’ or wheel).
GUESS which one wins?
The plane is fine - it’s the software that’s bad.
I do that on occasion with my wife’s 2017 Rav 4, you’re not alone.
Hit the stab trim cutoff switch.
Done.
Like I previously said, The tech should warn and inform the PILOTS, not take over control of the airplane.
Like “stall, stall, check your trim system”
The whole idea of letting the plane “TAKE OVER” (AI), control from the pilots is beyond DANGEROUS!
What are they “REALLY” trying to do with this?
Prevent Allahu Akbar pilots from crashing their planes (Egypt Air).
Eliminate unions? Computers have no need of the Air Line Pilots Association, (ALPA). (pilotless airplanes)
There have been several crashes where inexplicably pilots have forgotten to set their flaps correctly.
How about a warning system that says “FLAPS, FLAPS”, NOT the computer, on its own, setting the flaps.
Like I’ve said, they have had this type of problem since 1988 and they are still KILLING PEOPLE with it. Over THIRTY years and they still can’t get it right.
Air France Flight 296, an Airbus A320-111 On June 26, 1988, crashed when the plane’s computer would not allow the pilot to pull up and power up to avoid crashing. The “plane” knew better.
There you go again, inserting facts into a perfectly good thread. Fortunately, everyone is ignoring you, so this nonsense babble will continue until the traveling salesman weighs back in with his wisdom and insights.
“Alexa, are we really in a stall?”
“Hmmm, I don’t know that one”
Alexa, are we going to crash?”
“Here’s Should I Stay or Should I Go, by The Clash, on Amazon Music.”
The Greenies have another pile of bodies.
They modified the plane to save fuel costs.
We had those guys where I worked too. They were called “Console Operators”.
Really loud muslim, I believe.
My understanding is the First Officer was at the controls and had 200 hours flight time. Not 200 hours on this type — 200 hours total.
