Standard terminology gives you a couple of options: A) For a given runway, we have -- the arrival end, and -- the departure end. B) For a given runway, we have -- that runway itself, and -- the reciprocal runway. In the context of the active runway, there is a preference for option (A), for obvious reasons. In other contexts, for instance a discussion of displaced thresholds, option (B) would make more sense. > there's these displaced threshold and ... > Should I be checking them when computing my threshold point? In a word, yes. Officially there is only one threshold. If there is a displaced threshold, it is displaced relative to the beginning of the runway; it is not displaced relative to some "other" threshold.
