Although I understand you are only trying to be helpful and explaining the constraints put on you by others, the problem you face is that plenty of people have flown in the USA and seen how they do it. Over there, planty of very busy airports are Class C which generally has a 5 mile radius surface area, and which by demonstration is totally workable. So telling us it isn't workable is only likely to make people think you are part of the problem, which may not be the case. I agree that Mode C is very prevalent and this makes life a lot easier, but then as I said before, when Mode S comes along that excuse will not stand. I think I read somewhere that a massive restructuring of European airspace is on the cards, and they appear to be copying the FAA model, did I imagine this?
