I live in Sydney, about 10km from the airport. It’s not like LHR, with one runway for arrivals and one for departures. 16R/34L (in the real world) is used for both arrivals and departures for larger planes and most international traffic. The shorter 16L/34R is mostly domestic traffic B737 and smaller. Occasionally a larger plane like an A330 or B787 will use this runway but rarely.
I’m new to WOA, just started PRA, and only joined this forum today, so hope this info hasn’t been posted elsewhere and I’m doubling up.
