Not as simple a statement as you put out there, especially since, even after Lion Air, a lot of information and procedures on the MAX had changed without notice. Did you know the STAB Trim switches were changed in regards to what they did ( and Boeing did not mention that)? Did you know that the MCAS response was double what originally was intended, was programmed that way, yet Boeing did not tell anyone, some who even worked inside Boeing). How difficult is it to control an aircraft that is trimmed full nose down? Do you know? Again, your simple comment may apply in a simple situation, but this was not one, and the onion layers seem to get pulled back more and more as we continue to learn more and more.

Stuart. Southwest was disturbed to find out about MCAS after the fact. It was not mentioned in flight manuals nor in maintenance manuals (very minor mentions). A program that manipulated flight control surfaces without direct pilot input should be conveyed to pilots and airlines. Failing to do so shows a complete disconnect with what they are doing and who they are serving. Pilot error may have been a part, but the situation they faced was problematic at best, even for US Pilots flying the same scenario, all acknowledging that without altitude, recovery was doubtful at best. How many instances of runaway trim happened in US airlines since the MAX came out? Do you know? In the 2 accidents, the AOA sensor was defective or damaged. Did you know that that impacts Airspeed and altitude readouts as well? It is not just about responding to a runaway trim, there is much more involved. It was much more than just pilot error, and Boeing it appears raced to production a system that was not pro

Maybe passengers could blow on the windows?

Sharon, the sims that airlines use cost well over $10 million, even used. There are plenty of 737 simulators out there, just not one specific to the MAX, and that is the elephant in the room. Once separate sim training is needed for the MAX, the efficiency of having an umbrella certification for all 737's no longer applies to the MAX, and the benefits of purchasing one decrease.

They are currently looking at these procedures again to see if they need to be updated. Most training ends at "disable the STAB Trim". They don't go further and have a pilot fly a mis-trimmed plane through the event and land using manual trim.

MCAS made this procedure inaccurate. The stabilator was moving more than pilots realized and continually activated. Not so easy

My understanding is that it was reported, and it was repaired according to Boeing manuals. With LION Air, little was known about MCAS and it was not mentioned in most manuals. Before learning that, I weas under same assumption as you.

NTSB will always present their own report. They are not the regulatory agency and can only make recommendations. It is up to the FAA to implement.

Its not an anti-stall program
