What I find curious is that there are apparently a number of automated systems, on the ground and on the plane, that apparently weren’t in use or didn’t successfully clue-in the flight crew.
I would(perhaps naively) imagine that, by the time a plane has gone through design, testing, and manufacture, its properties would have been simulated to death, and the question “How fast should I be going now, if I want to land X meters ahead?” would be readily available for all but the nastiest ambient conditions.
