I am working on X-Plane 11.21
everytime I try to follow papi to land, then I found will overshoot "big white brick", then long landing.
then I watch your tube videos again and again, I found problem might be PAPI in X-Plane, when we close to runway touch down zone, PAPI angle is too high in X-Plane.
looking at real world PAPI , and runway ladder shape.
