Boeing Co. BA -6.15% is making an extensive change to the flight-control system in the 737 MAX aircraft implicated in October’s Lion Air crash in Indonesia, going beyond what many industry officials familiar with the discussions had anticipated.
The change was in the works before a second plane of the same make crashed in Africa last weekend—and comes as world-wide unease about the 737 MAX’s safety grows.
The change would mark a major shift from how Boeing originally designed a stall-prevention feature in the aircraft, which were first delivered to airlines in 2017.
U.S. aviation regulators are expected to mandate the change by the end of April.
Boeing publicly released details about the planned 737 MAX software update on its website late Monday. A company spokesman confirmed the update would use multiple sensors, or data feeds, in MAX’s stall-prevention system—instead of the current reliance on a single sensor.
The change was prompted by preliminary results from the Indonesian crash investigation indicating that erroneous data from a single sensor, which measures the angle of the plane’s nose, caused the stall-prevention system to misfire. Then, a series of events put the aircraft into a dangerous dive.
Focus on the update has taken on greater urgency as aviation regulators and airlines around the world have grounded their MAX fleets, following the Ethiopian crash over the weekend—despite no links being made between the two crashes by investigators.
The MAX software change is expected to take about an hour for each plane, a Boeing spokesman said Tuesday. He declined to offer other details about how the system would weigh the multiple data inputs.

H1B software engineers?
I don't worry about foreign educated engineers anymore than I worry about foreign educated physicians.
We have a perfectly good supply of domestic, home-grown mediocrities.
H1B software engineers?

Hopefully not. In the past I’ve worked with some of these who seemingly were employed at comparatively low salaries to rack up “billable hours” charged to the customer at much higher rates.
Fox just passed on report from Dallas News that 737 Max 8 pilots have complained to Feds for months about safety flaw.
[comparatively low salaries to rack up “billable hours” charged to the customer at much higher rates]
I won’t mention the name of my Big 6 employer (back then) who did exactly that. So nobody ask. Since you mentioned that very thing happening.
And yes, they’re still around.
Am I imagining things, or did they used to be called the Big Eight a while back?
These numerical designations make me think of other enumerated groups, like the Seven Deadly Sins, or the Eightfold Path.
“The MAX software change is expected to take about an hour for each plane, a Boeing spokesman said Tuesday. He declined to offer other details about how the system would weigh the multiple data inputs.”
It took hundreds of human lives to determine that any such software should have done that from the get go. Even a level one visionary could have foreseen this failure and the result of it. Boeing wanted to give computers this kind of power and they did not even plan for a basic sensor failure. Let them pay very dear for it. This is GROSS NEGLIGENCE. Maybe they will eventually even determine that the primary decision belonged in the hands of an experienced pilot and not in the hands of fallible computer hardware and software.
It matters not who writes the SW. if you have ever experienced the test of flight critical (safety of flight) software you would know that the final deliverable software, in many instances, bears little resemblance to the original. The test regimen is quite intensive. Now, H1B Test Engineers in the Verification and Validation phase would scare me
‘’H1B software engineers’’
Or, maybe, WV coal miners Obama told to learn to code.
I want the front line sensor to be me, and the backup sensor too.
I know nothing of software used in flying planes, so perhaps this will be nonsensical to say.
But, it sounds as if the pilots aren’t fully in control, that somehow the software is in control.
Do the pilots have the ability, I hope, to override software flight manuvers, so as to stay in human control and not crash?
Just doing the job Americans refuse
To do.
“Do the pilots have the ability, I hope, to override software flight manuvers, so as to stay in human control and not crash?”
Yes. There is a red button on the left side of the captain’s yoke and the right side of the co-pilot’s yoke that disconnects the automation and the crew can hand fly the aircraft.
FYI-——very long article,which I’ve read several times,about airplanes “flying themselves” —excellent.

The very epitome of software malpractice is a feature that actually causes the problem (crashing) that it purports to solve.
In recent times, how many crashes have actually occurred due to an excessive-angle-of-attack stall? None that I recall.
As I recall, the only Big Eight I knew was a collection of colleges for sports.
That's exactly the point in the Lions Air and Ethiopian Air crashes. Were the pilots trained to recognize the symptoms of a runaway elevator trim situation and know to shut the automated system off.
