The ai don't take any other aircraft into account once they are in the landing pattern, not yours or AI - thats as far as I can tell. They won't even react when under attack from enemy aircraft. I usually take the responsibility as to when it is safe to land, its not worth letting the AI decide for you. It would be good if the ground control was more complex and realistic, but as it isn't, I don't treat it as if it is.
