I was talking about the procedure you referenced i.e. the one where a vis assessment of distance available either permits or precludes the 'land after'. With ref to the original question, if a pilot is uncomfortable continuing for so long without the landing clearance, then he/she must go around.I may sound harsh and probably would hope they don't, however, that is their responsibility and can't be blamed on the ATCO, being given a clearance that is not safe can be.
