Good morning!
However, can somebody explain to me the advantage of constantly varying your airspeed during the final approach?
Try "
power for altitude, pitch for speed" on a slippery jet with slowly responding engines and you will know what the advantage is. And if you do it with some anticipation, then there is not much (unwanted) variation in your airspeed.
As long as your school trains mainly private pilots, there really isn't much difference. But if your school is aimed at ATPL students (like the one I instruct for) it makes a lot of sense to teach it the way they will need it later for their job.
