Mad!
Stick pushers are sometimes fitted when there are "stability issues approaching the stall" - in such a case, though, in order to fix such issues the pusher needs to be set to trigger BEFORE the adverse characteristics are manifest, with attendant likely adverse impact on stall speeds.
Very good point, and I flew two types with mechanical warnings. One plane had very benign pre-stall characteristics when leading edge flaps were extended as with normal landing configuration. So we had a "shaker". The other had a "pusher" that firmly kicked the stick forward. Subsonic, decent warning, but that sucker had zero warning when supersonic, so the "pusher" was nice.
More from Max:
If the issue is insufficient elevator authority/power to dependably recover from a stall under worst case conditions, nudging the stick will achieve nothing. In such a case, the solution is either more elevator authority (major redesign) for "help the elevator with the stab". The latter seems to be the MCAS solution.
Yep! I am losing a bit of confidence in Big B, although we saw a weak elevator in AF447 that took a long time of full forward stick to move the stab and recover from the stall. At least that's what some of the Pruners here saw in some sim tests.
