Secondly the minimum eye height over threshold might not be applicable to your type of aircraft.
So I would say yes you can continue without papi, not following the ILS anymore below sounds like something learned in flying school, how do we fly CAT II/III if the gs is not reliable below 300ft?
Thank you for your explanation,I fly A320 families,it happened to me many times that I have to keep 3 reds and 1 white to maintain profile at PVG Shanghai.
