Report established
Hello,
Just wondering your opinions on the following example in level flight on a heading:
"Airline, turn left heading xyz, report localiser established".
As far as I know, 'report' is not a clearance. It is to be answered with Wilco.
I've this example last week in LTN and several times in LGW recently. I had to ask the controller if were were cleared for the ILS, to which he replied Afirm.
In other words, am I right in thinking that without the full clearance for the procedure, we are not allowed to descend on it. I certainly wouldn't descend anywhere without prior clearance, so surely this applies. The same is true for the lateral section. Unless cleared for the localiser, how can I report established?
Your thoughts please.
TY
