______BYPASS the switch (and therefore make it ineffective)
i can see their logic there....but believe it ignores the fact that (presumably) such heavy aft stick forces would be used that no sensible pilot would continue exerting them... if they thought they were anywhere near the stall !
So justify leaving the Bypass alone... it's only yet another alteration to a known existing system, fingers off!!
Happy to be corrected...
