To me it doesn't make any sense that the pws would activate with such low g-values, which are most likely reached during normal ground ops taxi.
Surely you only turn it to auto when you would have the WX Radar on anyway? So if it’s safe for the radar it’ll be safe for the PWS. Having low activation values would ensure that if the WX radar was off for take off with the PWS in auto, you will still get the PWS operating early in the take off roll.
