"Turn left/right heading to intercept DESCEND ON THE GLIDEPATH! Cleared ILS XX"
So uncomplicated! Covers your back in giving the altitude restriction of the glidepath and saves RT transmission times by aircraft NOT having to call established.
I am a convert after having worked the old UK way before. It has been done to death on these boards because as has been mentioned..the UK seems to be the only place that has this confusion. The UK flights into YYZ all report established on the localiser even when they are not being asked to. Frustrating when busy!
Oh as for the giving the QNH with the descent on the ILS...ermm hasn't the pilot already had it on first contact...and first descent...why would they need it again on the ILS?? Unless it has changed in the interim?
