wind?
ie. are we ABOVE or BELOW the recommended IAS for this approach?
Because, no matter the glide slope, if we're above the recommended speed, we will float. The faster we're going, the longer we'll float.
If the glide slope is too high but the IAS is right, we won't float (we might bounce if it's too too high, and if it's way way too high then we'll splat), and if the glide slope is too low, but the IAS is right, we won't float either.
But if we're configured correctly, then we "should" fly the glide slope at the same speed as any where else (depending on wind of course), so we should be at the correct IAS.
