Interesting point Chev.. I can't find anywhere the recommended phraseology for lining up #2 to a departure. MATC Pt 1 mentions "after" a landing for lining up and for crossing. CAP 413 does mention the fact that "after" rather than "behind" is used in the UK to line up following a lander but it makes no mention of following a departure! Guess it's all down to local training. I said "behind" when I first arrived at Heathrow and Bill McColl gave my ear a bashing so I never said it again.
