In the UK now is the following used or would it work?
"Turn right heading 240 to intercept, leave 4000 on the glideslope, Cleared ILS 27R"
That covers localiser interception and when you want them to descend. Not sure what is appropriate as I have been gone for a while.
We use this in YYZ and it seems to work OK. I get asked by my colleagues why European carriers report localiser established..and the answer is because they are used to being told to.
