For a number of reasons, you fly your approach at a speed equal to or somewhat greater than best L/D (around 60 in a 2-32, for example), which is substantially higher than 1.3Vso (around 30-35). You use the spoilers/speed brakes to accurately control the glide slope, and to correct for the usual wind shear near the ground (diminishing head wind). L. Miller
