Good evening all.TC_LTN is quite correct,that is the phraseology we should all be using.The "when established on the localiser descend with the glidepath" is a mixture of the old and new phraseology and therefore should not be used.
The new phraseology was brought in to stop a/c being cleared for the ILS say 14 miles out and descending down to the lowest level at which the procedure starts straight away(which is why before the new phraseology we used the descend on the glidepath bit).I think there may have been an incident at some point or other that brought in the new phrase.
J see you later
