Eggs,
having worked in Europe and the UK I must say I couldn't agree more about the split phraseology in the UK for the ILS intercept. It wastes time in a busy environment and is outdated in my view. Worth a separate topic? Anyone from SRG reading this like to explain to me why we persist with this difference in the UK?
We got a phraseology change a little while ago that now allows us to say, before you've reported established on the localiser, "when established on the localiser, descend on the ILS".
Not quite what you're looking for but, when used appropriately, should stop those situations where you're left hanging above the glide because you can't get in to say loc established and receive the all important "descend on the ILS" in return.
Works for me at EGLL.
WF.
