Centreline lighting - left or right of the line ?

[Goldenrivett]

Hi buzzc152,

is there a reason to put the lights on the south side rather than the north or is it random ?

If you have parallel runways, then you put the lights towards the "inside" of the centreline so the power cables are shorter.
