Seen on RADAR - wearing a squawk issued by LHR SVFR and in the zone so
Mode C is then verified to be within 200ft of reported altitude. And no I didn't say anything as I was not plugged in controlling at the time.
The point I make is that as an ATCO, I really don't care what level you take. (as long as you stay out of the Restricted areas when off the river)
The CAA have stipulated "Not above 2000ft" on H4. My question is why fly at 700ft when cleared up to 2000ft.... in a single! (No this is not Robbo or Single bashing!!!) Surely this is a noise issue as well as a safety issue?
As for Mode S, we get downlinked parameters from certain aircraft displayed on our screens at West Drayton. We are the only unit in the U Kwith Mode S capable radars at the moment. We see Selected Flight Level, IAS, ROC/ROD etc - but NOT your Hexidecimal unique code.... yet! (I believe it is "read" by radar but not put on our screens)
