OK, this happened to me in Europe but I think it's relevant: taking off with parallel runway ops in process. ATC: "cancel SID, after takeoff maintain rwy hdg, cleared for takeoff". At 400' engaging HDG mode on rwy hdg resulted in a turn towards a 757 that had also just departed on the downwind adjacent parallel runway. This was due to the 25 kt crosswind. Presumably the controller had intended me to maintain rwy track but his phrasology was careless. So in spite of what the AIP says or what might be bleedin' obvious professionals still make mistakes in interpretation and execution.
I hope a wider perspective is useful to the discussion, after all alot of guys reading this will end up working in The Rest Of The World too!

Just to muddy the waters for you even more.

At bankstown, if you are given an assigned heading in a significant crosswind, but you maintain that heading within the zone and drift across the runways, you get yelled at :)

Maybe that's why the SID was changed (after Class D introduction) to include a track requirement (rather than assigned headings) :confused:

On second thought, that sounds much too logical :ugh:
