Your objective is to land the planes as quickly as possible while maintaining separation between them, and you do this by assigning them routes that lead them to final approach. Unlike others, all you can do is ATC
Simulators that let you directly vectorize planes, set altitude and speed, etc. This obstacle creates some challenge, as planes arrive randomly and violate the separation minimum unless you cleverly and actively assign routes.
To prevent conflicts, you have to be adept at reassigning routes and asking planes to join your routes at specific waypoints. To help you in your mission, planes slow down slightly if there is other traffic ahead of them, and there are speed restrictions at waypoints close to the airport to make higher density possible where routes come together.
