No, it would have more ground clearance, so it wouldn't need flat bottomed cowlings nor MCAS.
- _ph_ 5y agoThat is wrong. First of all, the 737 MAX doesn't have flat bottomed cowlings, that was its predecessor, which did not have MCAS. And the effect is fundamental to large engines. The effect which required MCAS would also happen if the machine had larger ground clearance and would be mounted more under the wings. Actually the way the engines are mounted on the MAX moves them closer to the longitudinal axis of the airplane and thus reduces and thrust-related tendency to pitch up.

- nemetroid 5y agoThe MAX does have flattened cowlings, though the effect is less pronounced than on the NG. Compare the MAX (right) to the completely round cowling on the A320neo's LEAP-1A: https://leehamnews.com/wp-content/uploads/2020/11/737NG-vs-MAX-nacelles.png https://leehamnews.com/wp-content/uploads/2020/11/737NG-vs-M... https://aerocorner.com/wp-content/uploads/2020/01/Aegean-Airbus-A320neo-frontal-1140x641.jpg https://aerocorner.com/wp-content/uploads/2020/01/Aegean-Air...
