There is more: the airframe of the 737 MAX is not in and of itself stable. Because of the forward positioning of the large engines, the MAX's airframe has a tendency to pitch up when accelerating. Boeing decided to fix this hardware problem with software. This is flawed design. In a multi-layer system, each layer should be intrinsically safe. The job of the higher layers should be to add functionality, not fix flaws in lower layers.
- mobilefriendly 8y agoThis is a fundamental point, the entire stack is broken. Fixing the software is just a patch. It is quite possible that in the end, the 737 MAX will be abandoned.
- tropo 8y agoAll aircraft with podded engines under low-mounted wings have that tendency to pitch up when accelerating. This is nothing new. The 737 MAX additionally has a tendency to pitch up when pitching up. The more you pitch the aircraft up, the more it wants to pitch up. As you pitch up more and more, you'd like the required force on the controls to increase, but in the 737 MAX it would naturally decrease.
