Schiphol, Amsterdam uses (or used) glide slope capturing from above. It was a contributing factor in the crash of Turkish Airlines Flight 1951. It was commented in the Mayday series: http://www.dailymotion.com/video/x18vk8d_mayday-s10e06-who-s-in-control_shortfilms, about 18:45 minutes. At 19:08 minutes they say “It’s a common practice at Schiphol because it gets planes to the runway faster”. Maybe they changed it after the crash.
ICAO DOc 4444 (PANS-ATM) says:
8.9.3.6 Aircraft vectored for final approach should be given a heading or a series of headings calculated to close with the final approach track. The final vector shall enable the aircraft to be established in level flight on the final approach track prior to intercepting the specified or nominal glide path if an MLS, ILS or radar approach is to be made, and should provide an intercept angle with the final approach track of 45 degrees or less.
…shall enable…
Fortunately, there are still humans down there who don’t get it right every time, every day. Otherwise we wouldn’t need humans up here who will find a way to fly a stable approach from a poor intercept. Hopefully for another 13 years, or I will not get my full pension
