Lion Air Flight 610 plunged into the sea off Indonesia because the pilot “lost (the) fight with his software,” Canadian Transport minister Marc Garneau chillingly told a Wednesday press conference announcing the grounding of the Boeing 737 MAX 8.
There is nothing wrong with the basic mechanics of the aircraft: Its engines, wings and control surfaces are all believed to be working fine. Rather, the passenger jet may have killed 346 people for the terrifyingly modern reason that human pilots were unable to override a malfunctioning computer.
The cause of the Lion Air crash — and the suspected cause of the recent downing of Ethiopian Airlines Flight 302 — is a little-known piece of software known as MCAS, the Maneuvering Characteristics Augmentation System.
The 737 MAX 8 has heavier and more fuel-efficient engines than prior editions of the 737, a change which causes the aircraft to pitch upwards ever-so-slightly after takeoff.
Rather than instructing airlines to warn their pilots of this quirk, Boeing simply equipped the MAX 8 with MCAS, a program that would automatically tilt the nose downwards to compensate.
In normal circumstances, the system is not a problem, but it only takes a minor maintenance error to turn MCAS into a deadly liability.
In the case of Lion Air Flight 610, the 737 MAX 8 had a faulty “angle of attack sensor”; a small blade sticking out of the cockpit that records the angle of the aircraft in flight.
The sensor was wrongly telling the MAX 8’s flight computers that the aircraft was climbing much more sharply than it was. As a result, pilots were left wrestling with an aircraft that was repeatedly plunging itself towards the ground for no reason.

I agree that that's true in many cases, but by no means in a majority of cases.
I am a flight instructor that occasionally is asked to give a required biennial flight review to airline pilots. In some small minority of those cases, those pilots can be overwhelmed by the workload that faces them in the general aviation craft they've been willing to rent for their review ride with me.
It may not mean they're similarly substandard in their usual front office, but it does mean they've over-estimated their skill at basic flying skills in a craft they don't regularly fly.
Sorry 2 different Land/TO scenarios neither related
“Me understanding is that this system does not function when the auto pilot is switched off”
Exact opposite. MCAS engages WHEN autopilot is switched off. And the special fun is that the pilots were never told the system existed. So they were fighting something that they didn’t even know was happening. They are supposed to decide that the failure is similar to a runaway trim tab and treat it like that, although that isn’t exactly what it is.
“mohammad can’t fly?”
Charlie Don’t Surf either.
If one faulty sensor can crash the plane then it’s a design flaw. A human would not make the same mistake. Yes, apparently computers can make mistakes.
...
That’s why there are humans in the loop. Any competent pilot can overcome a problem caused by that particular sensor.
I believe you are hot on the trail here. A pilot, not a Nintendo player in a uniform, would have handled this incident and thought nothing of it, just another day in they office.
no, the plane is focked up
bull shit. 26 times the nose went down. You want to try it?
no, it’s not
“Aaaand... Trump was right as usual.” And he is the only one that had the stones to call a spade a spade. The plane doesn’t work right, it’s spring break, ground the focker.
China
The problem is Boeing didn’t build a plane that is safe.
” a series of complex steps “
in english Flip 2 switches
but if you did not know about the switches it would be hard to turn off the rouge AI.
I had a Cadillac cts that had the traction control turn off switch inside the glovebox. (I know this only cause I read the manual) I never used it during the time I owned the car, but I was aware that it existed.
Two crashes, in two Third World countries, with at least a hundred million Muslims.
I’ll make up my mind after I read ALL the evidence.
By the way - Ethiopia refuses to turn over the Black Boxes and Control Tower and Cockpit tapes.
Have any USA investigators examined the Boxes or the tapes from the Indonesia crash?
Bottom Line - at the moment, these are just Third World despots trying to extract the maximum amount of money possible from Boeing.
” “The 737 MAX 8 has heavier and more fuel-efficient engines than prior editions of the 737, a change which causes the aircraft to pitch upwards ever-so-slightly after takeoff.”
Then that’s the real problem that needs to be fixed, not the faulty software that was a band-aid for the problem.”
Bingo. Then you don’t need the stupid software fix.
I saw the Ethiopian black boxes are in France.
Who’s gonna do the analysis?
“More like Mohammad can’t land safely.”
YOu don’t get it do you? Your distrust of Moslems overrides all. The plane’s operating system is FAULTY. see now?
And we're going to have driver less cars?
I did not write that clearly.
I meant Ethiopia had refused to turn over the Boxes and tapes to USA investigators.
