From the perspective of someone dealing with stats daily I’d go along with Rob’s, Marcio’s and ChristiaanJ’s view on them, i.e. not just how many times out of total arrivals was any TL positioned incorrectly, but also how many times did it happen when a thrust reverser was pinned. Both índices are valid for study. If of course such data in thousands of landings were available and reliable and, of course, if AI had a way of monitoring it. Suspect no and no, ideal vs possible.
