Obviously this could not have been corrected by adjusting the elevator cct feel so it explains the why of why did they do it this way
This is a part of what I've been working on- where did you read that information??
Everyone has been focusing on the failure modes of MCAS and related components, but there has been little discussion about how stupidly huge the whacks that MCAS takes at a relatively minor (so we have been told) control feel issue. MCAS is, no two ways about it, a control system, one that exerts immense authority over the most important control surface on the airplane. Such a system, that sits unmonitored and unapologetically inserting itself when required, is unlikely to have been created in such a way without there being an equally significant issue that needed to be dealt with. Quickly and with huge control inputs.
THanks for sourcing that information-
