Exactly. Except it’s not flow separation that is the problem. It’s the lift that the nacelles generate combined with their mass and moment far ahead of the center of gravity
It wants to keep pitching up because the engine cowlings are now far ahead of both the center of gravity and the center of lift. And the cowlings generate significant lift themselves. Aerodynamically they act as levers…
Couple of things here to keep in mind. First, when the A320 came out I wrote extensively about its fly by wire system, which was highly controversial at the time (early 1990s). It’s been nearly thirty years since then…
