Another hint:
At that moment, you should also consider your height over the threshold.If you cross the threshold higher than normal, the additional landing distance can be roughly estimated as 1 foot for every 6 meters. 1:6
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.
