"hitting the glide"

[dogbros]

Is it true that you are not allowed to intercept the glideslope from above? (me thinks this is correct!!) If so, why is it illegal to intercept the glide from below at some airports because it involves a level segment. I know some airports require this as part of their noise abatement. So it is physically possible to do so but why can't aircraft capture the glide from above at other aerodromes. Comments please! <img src="redface.gif" border="0">

Methinks it's not illegal to intercept from above, rather it's considered bad practice. In reality nothing wrong with it provided you know exactly where you are and are sure you've got the right one.
