Interesting.
I regularly fly across the very very extended centreline of EGLL 09L/09R under the CTA, which at that point is 2500' (over Henley area). So the controller would see converging blips (me and an inbound IFR) and have to assume the uncontrolled traffic is at the correct height? (if I wasn't squawking of course which is very unlikely).
There are no safeguards?
