Four parallel runways designation
Hi all, I have the following question regarding the "title" object.
Let's discuss the LAX and CDG airport case:
-LAX: landing West, the two couples of RWYS (the Southern couple, 25 L/R, and the northen pair 24 L/R have the same magnetic orientation: 251, and therefore the opposite ones, 6 L/R and 7 L/R have 071). The designation is 25s for the Southern and 24s for the northen (and 6s and 7s for the opposite)
-CDG: still landing West, for a similar RWY layout, we have: Southern RWYS 26 L/R (orientation 266) and for the northen, 27 L/R (same orientation).
Now: after all this, knowing that and addition of Ten degrees is added to differentiate the two set of parallel runways, is there any logic in giving "this extra" to one set or another?
Does the "preferential landing direction" (no wind), play a role in this scenario.
Thanks a Lot.
