Somebody’s got some ‘splainin’ to do.
This is going to end up being the most expensive “cost savings” in the history of Boeing.
Clean the sewers and ready the barges...Wall Street is about to take a DUMP!
A good friend of mine an ex Air Force Pilot and civilian pilot flew 737s 25 years for Southwest. He was not a 737 Max captain but flew the earlier models. He is an engineer. He explained it in very simple terms.

The AOA indicator lets pilots know if one of the AOA sensors is not working, while the disagree alert shows if the sensors contradict each other.
Mentour Pilot on You Tube has some good discussions on the MAX aircraft and MCAS.
MAX, as opposed to other Boeing designs, needs MCAS because of the size and position of its engines. It would be a lot easier with MAX to hit the throttle as an attempt to get out of a stall and pitch the aircraft into a worse stall, than with other Boeing craft.
But suppose MCAS fails. Now what.
Boeing’s 737 MAX’s REAL problem.
“To handle a longer fuselage and more passengers, Boeing added larger, more powerful engines, but that required it to reposition them to maintain ground clearance. As a result, the 737 can pitch up under certain circumstances. Software, known as the Maneuvering Characteristics Augmentation System, was added to counteract that tendency.”
“But some aspects of the legacy 737 design are vintage headaches, such as the ground clearance designed to allow a staircase that’s now obsolete.” (”the Boeing 737-100 had folding metal stairs attached to the fuselage that passengers climbed to board before airports had jetways. “)

Repositioning of the engines is a fatal redesign flaw. One they can’t take back. Everything they do after that are attempts at mitigating their fatal mistake.
Discussion in Boeing boardroom:
“What is the cause of this dangerous pitching up problem and how do we fix it?”
“The problem is we made the engines too big and moved them too far forward.”
“Well we can’t do anything about that NOW, what else can we do?”
SINCE this is from CNN, it must be assumed some error in reporting occurred, that the entire story was manufactured from the tiniest, misunderstood morsel of truth ...
Three authors of this article, and not one of them can get a simple detail right.
The AoA Indicator lets the pilots know the angle of attack of the aircraft, as displayed on their Flight Display.
Asshats.
Sales guy: Let’s offer this critical information at a upgrade price and bury the details on how to recover the airplane in the manual as well.
