I just tell the people I am teaching to line up with the run way come back on the throttle and dont fight the plane. I have found that once you have lined up correctly you can pull the power back and pretty much let the plane settle all the way in until the flair. This does not mean the plane will land by its lonesome. Just that sometimes people learning to land tend to put input where input is not needed. If the plane was built and trimmed right then you shouldnt have to mess with it all that much. (Unless there is a stiff wind)
