Showa Cho. I find it extraordinary how people on here take umbrage at the simplest statements but I am sorry if I have upset you as that is the last thing I would wish to do. Experience is an important factor on how we carry out our tasks, which is why I offer mine on PPruNe.
There seemed to be confusion which I tried to clear up. I have worked at international airports, a busy (very) training airfield and a run-down tip of an airfield and I have never, ever, told a pilot how I am providing separation. Traffic information - yes, of course, a million times - but how and why does one tell a pilot how one is providing separation? You might just as well ask a pilot how he reduces speed!
