Never assume that if you are in two-way with a radar unit you have been positively identified unless you have been asked to "squawk ident", do at least a thirty degree turn "for identification", or been handed over from your previous frequency.
Funny that. In France, and more or less everywhere else, they seem to know exactly where you are, all the way down. Hey, that's what radar is for. If the Russians invaded, you are not going to call them up on 121.50 and request a 30 left for identification. Radar is a really clever thing - it shows this blob on the screen and that's where the plane is
It is in the UK where they either don't know or are not allowed to let it be known (one cannot tell which it is) - presumably because an ATCO who is not radar qualified (and paid the higher salary) is not allowed to let it on that he can see you.
