Honestly, I wouldn’t want to see all three runways in HKG used for landings like in BKK.
07L/25R – landings only
07C/25C – departures only
07R/25L – both landings and departures
I think that would be the most optimal setup (and if I’m not mistaken, this is actually how it’s used in real life, based on this message: General Pre-Release Discussion - #140 by TechnocraticAviation ).
