MCAS caused the "overspeed" (or more importantly the speed achieved in the dive caused forces on the HTP that made it impossible for the crew to trim / pull up) by constantly putting the aircraft nose down. I"m afraid the timeline doesn't support that assertion. The aircraft was in overspeed well before MCAS entered into action. Of course, MCAS did increase the speed even more. from the hearing today explain why you always run into overspeed problem Only way to mitigate overspeed is to put thrust idle and I don't think any pilot will cut off A/T during emergency unless that's the root of the issue since it conflicts with their training and adding workload. It is also counter intuitive to put idle thrust after takeoff without having such recovery training especially when you don't have altitude.

from the hearing today explain why you always run into overspeed problem I'm struggling to understand what you mean, but that may be because I didn't listen to the hearings, experience having taught me that such political events are used for posturing only . From October 1st to October 3rd, we had a discussion about overspeed in the Ethiopian Airline crash. I initially just mentioned it, saying 'that's without even talking about overspeed'. You then wrote a long post, concluding that 'overspeed was impossible to avoid'. I was unconvinced as I had in mind that overspeed existed before MCAS entered into action, and pointed out that the pilots 'could have used the throttle to make a correction at different moments'. Stealthmanbob and Mjoelnir - who called my post 'nonsense' as he usually does - sided with you, both of them stating that MCAS was the cause of overspeed. You argued further, politely characterising my post as 'BS'. I left the discussion there, thinking that we would have no answer before issuance of the final ET crash report. Was there actually any new piece of information from the hearings ? If not, I suggest that we wait for that report for clarification. If I was wrong about overspeed, then I'll acknowledge it immediately.

If I was wrong about overspeed, then I'll acknowledge it immediately. When MCAS started activation in the Ethiopian crash the frame was in normal climb. Where can you find overspeed on a frame in normal climb? What information do you need to accept, that there was no overspeed before MCAS acted? The other way round, where do you find the information, that the pilots in the Ethiopian crash,stopped climbing and pushed the nose of the frame down to increase speed? You should come with a base for your claims.

What information do you need to accept, that there was no overspeed before MCAS acted? As already stated, the final accident report. I'm not resuming the discussion before the release of that report.

Why do you than declare that the Ethiopian frame was in overspeed before activation of MCAS, when you do not want to point to the base for it or want to talk about it. When you want to wait for the release of the report, why do you than make unsubstantiated statements?

No overspeed before MCAS kicked in - correct. "Overspeed" my have occurred when the aircraft was pitched Down repeatedly by MCAS, this resulted in making it virtually impossible to trim the aircraft using the yoke and or the manual trim wheel.
