I often test my regime by taking on the challenge of ATC at KLAX on TS1. Today wasn’t such a busy day, but every time I have a massive line up for 25R and 25L, both from inbound and outbound traffic, but almost nothing at 24R & 24L.
If you’re on the ground, and you see that a runway (at a multi-runway airport) is busy, try to stick away from it. If you’re close enough to another runway that isn’t busy, go for that one! I understand that if you’re on the southern terminal of KLAX, you’re not going to taxi to 24R/L, but if you’re in the center try to look for a clearer runway
Secondly for inbound traffic, try to avoid the crowded runways. If you are filing a FPL, try to line up with the northern runways, as it makes a controller’s life a lot easier to have inbound traffic coming in on a less busy runway.
Here is how I run KLAX. It works quite well. If you spawn in the center of the runways your going to 24L, if you spawn on the south side of 25L your going to 25L. No exceptions. It keeps runway crossings down to a minimum and generally only leaves 24L to be crossed by inbound traffic coming off runway to terminals
