I work with experienced pilots as well as tyros and both types have trouble at times. Generally pilots who are familiar with short fields find it easy to make a precision landing, but those who only fly C182 or the like have never learned how to do it. Students cannot handle two things at once and I am of the opinion that glide path control to a landing on the nominated spot is the most important part of learning to land. Using the elevator to establish and remain on the glide path seems to work.
I am grateful for the advice and information given to me here. I am relieved that I am not completely off the wall.
