Up in the post you quote, xetroV, I pointed out that the Landing Attitude Modifier was added to reduce the likelihood of a nosegear first (or tailstrike) landing. We all know why they included MCAS. But for this third hybrid FBW system, I left the reason why at "?" It raises questions, all right. Since 1968, the 737 has had a solution to a jammed elevator that has been accepted ever since. What happened that prompted a change? Was it just a new opportunity? "Hey, we've got these new FBW spoilers, what else can we do with them?" Something changed in the legacy jammed elevator system? Or just to add a new system to the list that is going to require engineering, testing, and certification? I sure don't know. The next question is, will they continue to be controlled via one set of sensors, and one FMC, or will they get the same input upgrade that MCAS is anticipated to get?
