Look, I am an ultra lightweight pilot and fly experimental planes a lot. FAA requires, and doesn’t F around with, that all airframes must be aerodynamically stable. So let’s throw that out right now, the airframe is not the issue. The engines push the cog forward which causes more lift at high thrust. This is not an airframe issue but a loading issue. FAA requires load limits and practical methods to check and resolve loading issues. Let me pause here. We can simulate the 737MaX design by taking an older 737, filling with 1/4 passengers and load them all in the front of the plane. Tada we have a forward cog scenario. Could the plane fly? Sure but the plane will want to nose up more than usual. What does the flight manual say? Reseat passengers to fix cog over limits, or limit throttle inputs if not over limit. So would a properly designed MCAS system solve this problem? Yes. But Boeing didn’t properly design MCAS the second time around.
