MCAS was added because the stick force gradient in high power, high alpha situations was not adequate for it to be certified under applicable certification standards. It has nothing to do with a common type rating. Even if it were its own type rating, it would still need MCAS, or an aerodynamic fix, which they couldn’t effectively engineer, so they went with MCAS.Originally Posted by sailingfun
The Max is stable throughout its flight envelope without MCAS. MCAS was added to insure a common type rating and that there would be no required sim training for transition. The A321NEO on the other hand has actual stability issues in its flight envelope discovered after the Max issues. Currently that’s being managed with CG restrictions however a software fix is in the works. Some operators have to block aft seats.
