I always wondered why Boeing did not fit one to the 737MAX.

In Stall identification (augmentation) is an action - it is doing something to the airplane to push the
nose down. Stick pushers and stick nudgers are commonly used for stall identification. A stick
nudger would have performed nicely in place of MCAS, but that would have required redesign of
the feel system.


I wonder how much it would have cost in terms of: delay, engineering, per-plane hardware -- and how
that compares to the costs of some of the high-tech solutions being proposed (genuine question).
