Thanks guys. The company concerned apparently cannot input ad-hoc waypoints unless they are published in the AIP/Jepps/Aerads - I asked and suggested they put one in themselves, after consulting their nav. people and carrying out the necessary risk-assessment etc. It's a thought.
Yes, I take the point about heading - fine if you have a parallel runway situation and want everything departing off both runways to fly the same initial track without fear of confliction. Does anywhere have parallel IFR departure runways, incidentally?
More comments please, with or without the influence of booze. All offers gratefully accepted. How come everyone on this web site is so damned coy about their personal profile? Or am I just naiive enough not to worry about being identified...?
