This was just added to the Canadian AIP: Glide path installations generate a radiated signal resulting in a normal glide path angle of 3deg (it can currently be anywhere from 2.5deg up to 3.5deg). The normal antenna pattern, of glide path installations, generates a side-lobe. The side-lobe pattern produces a false glide path angle at three times the set angle (e.g., at 9deg for a normal 3deg glide path angle).
I've never been so high on an ILS that I've seen this, of course, but it's interesting, and should be an easy effect to model. Any volunteers?
