Chevvron and all,
ICAO allow for three kinds of departure, straight ahead, turning, and a third category, when 1 or 2 can't be accommodated.
For 3, there are a considerable variety of combinations and permutations to achieve the desired result, ie; not hitting anything all engines or engine out.
Of the departures mentioned in previous posts, with which I am familiar, all are in the third category, all meet ICAO requirements, but some of the operating requirements are "interesting".
Tootle pip!!
