Generally ATC means Air Traffic Control, And also as the Top question states PPLs in training and qualified normally means the obvious VFR Flying..
As for you Frontlefthamster, You sound as silly as your name to be honest and all I was doing was asking a question to start off a different thread, if you dont want to answer then I suggest you go back to flying your microlight, Drill of the day questions normally come up at flying schools whether your trained or not to test your air knowledge.
Switch on Lofty!!!
