And then there is a place like Quito, Ecuador. If one were to stay on the ILS Rwy 35 glide path to touchdown, one would touch down 830m beyond the threshold of the 3120m pavement. Since airport elevation is at 9228 MSL, it would not be an option to keep a heavy wide body pegged "bull's eye" all the way to touchdown. In fact, at 9850' (652') DA, one would transition to the VASI which slopes 2.5 dots below the ILS glide path.
