Landing approaches and low speed passes are the way to learn how to line up for the landing. I've always included in my flights a low "landing pass" or 2 in my pattern of flying, no matter what maneuvers I decide to work on. The reason is it always reinforces to me where to break my turn to line up. Always pick an object or a general area to line up to at the end of the runway.( plenty of fields have that "plane eating MONSTER of a tree out there! ) Pick you reference point and when looks like you should turn to final hold it a tad past that point and that's when you nail it down the middle of the runway. I always have to delay my want to turn by a split second from when I want to, then cut the turn and I am usually lined up dead center. Depends on the plane as to how hot you land it. Best way to check that is to take it up 300-400 ft up and cut power and glide to a stall and watch it. I have some planes that need to be flown to the ground, and some will settle and drift on in. Just takes time and practice with each plane. The low passes are also cool, just because you can see your plane zoom by and you know you have full control.
