Ethiopian Airlines flight’s stall-prevention software was active at crash, CEO says
The chief executive of Ethiopian Airlines told the Wall Street Journal in an interview published today that he had reason to believe that software intended to prevent Boeing 737 MAX aircraft from stalling in flight had been activated aboard Ethiopian Airlines Flight 302 shortly before its crash. CEO Tewolde Gebremariam said that “to the best of our knowledge,” the Maneuvering Characteristics Augmentation System (MCAS) for stall prevention was active at the time of the crash.

exactly, worst of all the control surface moved by MCAS is twice the size of the one operated by the pilot, guess who wins.
People been trying to build idiot proof airplanes since the Wright brothers. You learn about stalls from day one of flight training. Flying Rube Goldberg machines aren't the answer. Practice practice practice is. Just like how you get to Carnegie Hall.
Blame the automation, blame the crew, just like in politics people pick a side and go all in, reality be damned. These accidents are entirely typical real-world aviation accidents....the cause was a confluence of factors. The automation folks should have thought a little deeper into the “what if” tree and the crew should have been able to recognize runaway trim (howcome those big wheels next to my leg are spinning like that?).
What makes this one so riveting are the ancillary factors, particularly the Lion Air. How could the crew have been seemingly unaware of the problem after all the publicity over the first one and the fact the aircraft they were flying was known to have not only experienced the problem on its last flight bur it’s crew on that run was saved from the same fate only because a deadheading jump seater said something like “Ah, why don’t you turn off the trim so it will stop doing that?”

DAMMIT JIM! If there were just a way to turn it off! Oh, there IS a way. It’s called the “Trim Cut Out Switch”!
Boeing must explain why the 737 Max cannot be certified without the MCAS system or I will never board it. This system is either required or not, if it is required to prevent a stall and you weaken it now does it mean that aircraft will be allowed to stall, this is getting confusing.
Does that make sense?
