Could you just clarify for a lowly, long retired Ops Director (so rather out of touch with today's SOPs), is it now standard practice to commence a CAT I approach with a DH of, say, 300' when METAR cloudbase is BKN or OVC at 100'?
I ask only because it seems to be generally stated on this thread that RVR is the sole criterion for deciding to commence an approach, regardless of the reported cloudbase, presumably in hope of finding a cloud break at DH.
