At DA you need visual reference to continue (BIG CLUE) or go around, so if you have visual reference you land visually, now this may come as a shock to some, but why would you want to follow glide path?
Framer
We operate into a couple of airfields where the TCH (threshold crossing height) is negative on an ILS !!
So following the glide path at Bardufoss ILS 28 after DA would bury you, the TCH is -25' i.e. 25 feet below the threshold, so at DA you fly visually to the touch down zone.
At DA aim for the touch down zone, if your stable at DA and the PAPI are set for an aircraft with a higher eye crossing height why upset things by adjusting up to the PAPI you will likely bleed speed off and increase the risk of a tail strike
