"Force control issue" is Boeing-speak for "anti-stall." If you're holding the stick back, increase thrust, backwards pressure on stick needed to lift nose reduces, you stall and die.
What we don't know is how often MCAS actually operated on flights, so we don't know how necessary this component really is. All we know is that Boeing claims it's 'rare' and the FAA did not challenge them on this statement. Unless you have the data, you're repeating their talking points.
- kayfox 6y agoEngine thrust related nose up forces would be less on the MAX as the engines are closer to the CG and CL. What is being compensated for is the change of the center of lift as the AoA changes because of where the engine nacelle is and how big it is. Also, the data that you are expecting the FAA to report on was not being collected by the FAA. You will also note the FAA did not provide any data on how frequently the TOGO switch is used in the Atlas Air investigation, because just like MCAS it is a system that may be activated on normal flights.
