Ok so maybe I have learned something incorrectly somewhere in my training. I am studying for my CFII and recently was reading up about the ILS from the book "asa - The pilots manual instrument flying". I came across the correct procedure to maintain glide slope as well the procedure for regaining the glide slope. Change pitch attitude to regain glide slope and power for airspeed. For Ex. If above glide slope, lower pitch attitude slightly and adjust power to maintain airspeed. What I was taught and was planning to teach is: Once the airplane is setup, trimmed and configured for an airspeed then it is simply reducing and managing power to achieve a rate of descent (Pitch for an airspeed and power for altitude). If below the glide slope add some power to slow the rate of descent. If above the glide slope reduce some power to increase the rate of descent to regain the glide slope. The airspeed remains the same. It seems like there is less to manage the way I planned on teaching it. Adjust the power to maintain and find the correct descent rate (Ground speed x 5 = correct rate of descent).
Anyone else teach it the way I learned? Any comments or suggestions?
