For example, if you cross the threshold at 100 feet, you’ll need about 50 × 6 = 300 meters more runway than what was calculated before the approach.From this, you can quickly decide whether to continue the landing or go around.
Since there's a TDZ marker every 150m, that means each 25 ft more above the threshold means touching down one marker further along.
In what kind of situation would you decide that on the go?
I imagine that when you prepare the approach, comparing LDA to LDR, you'd think about what margin you have, as in "I have 300m I don't need, so it's still ok if I come in 50 ft high" or something like that?
or do your company SOP define margins for "hot and high" which mandate a go-around if you exceed them?
