You're the air traffic controller. Guide every aircraft on your radar safely onto the runway, or hand it off at the edge of your airspace. Here's the whole game in four steps.
Every blip is an aircraft with a heading, altitude and speed. Tap one to select it and see its details.
Turn it onto a new heading, climb or descend it, speed it up or slow it down, building an orderly stream toward the runway.
Line arrivals up with the runway centreline to land them. Send departures out to their exit fix and hand them to the next sector.
Two aircraft too close is a conflict; a collision ends the run. Plan ahead, stay calm, and keep the sky orderly.
Start at a quiet field on Novice difficulty, one or two aircraft at a time, then work your way up to JFK, Heathrow and the busiest hubs in the world.
