Ok, let me start again Bergerie. I'm well aware that the lights will APPEAR to the left or right from the perspective of someone standing at one end or the other. That's pretty obvious and quite clearly not what Im getting at.
Let me ask it in a different way. Let's take a runway, 27/09. On this runway the lights are on the south side of the centerline, and will always be on the south side whichever way you approach it. My question is ; is there a reason to put the lights on the south side rather than the north or is it random ?
Not sure how else I can ask the same question.....
