And I am curious to know what happens if the weather goes below night visual limits e.g. under a TEMPO? You cannot issue slots to keep all the inbound transatlantic flights on the ground, because they are already airborne.
Similarly, how does KSFO cope when the weather is well below night visual limits for longer periods? If they are so busy that only night visuals can accommodate all the inbounds, how do they cope when the weather is well below?
(I have only ever done ILS's into KSFO, with single approach runway operation - it was usually after dark but not busy, at the times we arrived).
