One thing I don't see discussed is the relativity of what constitutes a stabilized approach. Within SOP is a given... but a low time in type pilot needs to be on a much more accurate profile (i.e. centered on the PAPI/VASI) and completely set up in landing configuration, while a more experienced in type pilot can accept a bit more, for lack of a better word, slack, in the parameters (e.g. all whites, thus high on approach and possible long touchdown on a suitable runway/airstrip) Of course, SOP must be the governing principle, as well as operating regs (135 or 121) in a given country as well as the registered country of the aircraft.
I think that, at least in the FAA, the "rules" are intentionally centered around an operators approved SOP's, to allow for this sense of relativity.
But, as always, "Aviate, Navigate, Communicate", and when in doubt, go around and reset.
