point he could descend below the glide slope to have more runway available to him at touchdown. A normal 750 fpm rate of descent would then go to 1200 fpm to accomplish that. Most of us have done it many times. I have many times with positive results. It was done below 200 ft. Check the CVR.
As an ATCO for a RWY with 800m displaced papi on one of the RWY ends, but with all 800 meters available for landing (not in LDA) I've seen this a lot.
AND I've seen crews doing this when they have to much energy on short final.
Result: They land long after the PAPI as well, after floating 800m plus.
