You learn the feeling of what a stall feels like at the very beginning of your flying lessons. A stall is a stall. There is a stall warning already built into the system so you can manually compensate. Why try and let the plane do this automatically?
Have you ever flown a transport category turbojet? If you let the stall progress to the point you do in primary training you are dead if below 10,000'.
If you want to sell your new series of 737s as compatible with the old, requiring only minimal pilot retraining - it is. Looks like that's what happened here.
Boeing built an aircraft with substantially changed aerodynamics, but has type commonality as a huge selling point. So they put a software shim between the pilot and the plane, making the new plane feel like the old one. That works right up until the point where stuff breaks.
That isn't why MCAS exists. The MCAS system was installed due to an FAA requirement for control pressure being above standardized certification guidelines to recover from stalls in certain situations.

I'd say that depends on which sources you listen to. And "control pressure being above standardized certification guidelines to recover from stalls in certain situations" could mean a lot of things.
Pretty obvious what has happened here.... MAX8 MCAS software had bugs which required astute pilots to understand and mitigate. Southwest, and otherUS airlines probably realized this after, if not before, the INdonesian crash.
Boeing probably knew, as did many airlines, exactlywhat the probable problem was, and how to negate it. More than likely, they also knew the next software release would fix the problem and were hoping nothing bad happened, but then Ethiopia did. They rolled the dice, came up snake eyes.
I’m willing to bet Boeing will have this fixed in record time..... because they already knew the problem and fix, butwere hopingto sneak the fix in without adverse consequences.

Yes, the fix has already been done (software / code wise) + the manual override was provided in Operational Control Bulletin.
But...This will not be quick to "Return-to-service" 3 months - 1 yr I will guess (to re-qualify-FAA)
They still won't have the full understanding of latest crash that soon.
I am not convinced a 28YO 'Senior Captain' backed up by a FA with 200Hrs qualifies for "astute pilots"
I feel better with some 'gray hair' in the cockpit.
Probably when DC-10 had some crashes in 1970s or Airbus made entry in United states, Boeing made up this. Now they have a reputation to fulfill otherwise this phrase will get reversed.
Why doesn't Boeing consider that the design of the MAX may be part of the problem > engines located closer to the fuselage. It seems they are going with better training of pilots worldwide and new software.
Placement of the wings must affect the aerodynamics in some way.
