The normal pitch blade angel should be adjusted just as it is nowadays.
That "ultra low" section of the pitch level travel would require considerable force to overcome the "protective spring" to get into and hold there.
Hence w/o actually postitively and deliberately wanting to go there one would
never reach that range. It should be an eyes popping out, "we're all gonna die" emergency option only.
Nevertheless pitch angle adjustment precision during maintennance would be more intricate, that's for sure.
