Outside Europe/US there are parts of the world where they have no idea what you are talking about when you ask them how to use the deck markings correctly.
Hand up to that until this thread came along. Long retired, but we seemed to operate OK by being cognisant of the layout of the platforms (someone mention airmanship?). Same as if you were operating into a restricted area. If someone broke down, the aircraft was positioned on the very edge of the perimeter, and the rescue landed alongside, with the "H" twix the two aircraft. I know some of you are going to cringe, but it had the full approval from the highest of the high. Times do change but.
