It's a descent technique which you can use if you have a fixed point to aim at e.g. a runway threshold. Attitude controls flightpath and ideally now remains fixed relative to the aiming point, and power is used to control airspeed. It does rather hinge on achieving a fixed point on the glidepath (400' point in RAF teach or 500' point otherwise [or letterbox, having now read the other thread]) which sets you up at the correct angle (3 degrees or so) but thereafter it's an effective technique which I believe translates well onto larger and heavier aircraft. I haven't read all of the other thread (but will in a moment) but you do still have to trim if you vary power.
