An important element that is learned by the student pilot 'by just keeping on doing it', is to maintain the right attitude and rate of descent during the approach. Gradually one learns to 'see the picture'..... of how much nose cowling can be seen, and the perspective of the runway. It can be difficult at first if you are landing on different sized runways, as one must make a mental adjustment to the 'picture'. The numbers on the runway are an important pointer whether you are going to overshoot or land short.
