They cannot do that, because then the Max loses its shared type rating due to the larger engines. MCAS exists to give the aircraft more similar flight characteristics to its predecessors.
- tzs 8y agoMCAS apparently exists for more than that. A few days ago someone posted a link and some quotes from the FAA regulations on pitch stability. They require that the control force must be positive up to and throughout a stall. Without MCAS there would be a point on that MAX where you no longer needed positive control force to continue pitching up. Without MCAS or some other system to automatically counter that, so that the pilot needs positive control force to continue pitching up, the plane could not be certified even if they did go for a new type rating.
- chipsa 8y agoIt's not that the force must be positive. It's the the force must be consistantly increasing up to the stall as well. Without MCAS, the problem is that the force does not continue to increase to the stall point. It does stay positive at all times.
