I have seen some guys chasing aggressively the papi even below 100 feet from touchdown resulting in high thrust variations and sketchy landings. From what I have learned, below 100 feet do not chase the papi: Accept what you have even if the Papi says you are slightly too high or too low, at this stage it’s too late. Keep the same pitch and constant ROD around 600/700 feet/min; By doing so the thrust is constant and a safe landing is pretty much guarantied. Many times I have seen skippers trying to be perfectly 2 white 2 red until touchdown and ended landing far due to over controlling and high thrust variations during flare.
