I give you an example just to show you my doubt in a clearer way.
If in your airports (EGLL, EGKK, EGSS,...) you have a landing sequence with two aircraft under separated (1.5 NM) and you want to avoid the missed approach for the second one, which procedure do you use? And if you have 2000 mt. of visibility or 7 kts of tail wind, you'll give anyway land after ??
