All of these are problems I’ve come across when running a very big airport.
All of these problems only exist/get much worse at the top game speed.
- Planes have to go around far more often
- Security officers don’t staff the Tier 3 scanners (allowing dangerous baggage to reach aircraft)
- Vehicles stop moving properly causing tailbacks (don’t speed up when game speed increases)
- People don’t buy from shops/food outlets
- Auto-planner doesn’t always work properly (large stands don’t always get flights assigned to them even when available)
