"The change, however, affected the plane’s aerodynamics. Boeing discovered the new position of the engines increased the lift of the aircraft, creating a tendency for the nose to pitch up."
The problem wasn't just the ground clearance. the problem was that aerodynamically had issues (not so well balanced probably). So when they were trying to fix "this" something else was breaking and so on. That's why they introduced this MCAS software in the first place. It wasn't some new fancy tech but it was just a system to help with the bad 737's aerodynamics.
- iguy 8y agoRight, but it sound like the aerodynamics have been deteriorating model-by-model, as they move away from the original design. This creeping change must be really hard to regulate right. A terrible new design you could refuse to certify, but a terrible one which is only a few percent worse than the one your predecessor certified a decade ago... it would take a lot of confidence to say no.
