About Air Traffic: Greenlight
Air Traffic: Greenlight puts you in charge of a busy sky, where you must keep planes moving safely despite limited radar reach. You’ll juggle wind, terrain, and runway constraints while preventing collisions and fuel emergencies.
The game draws on real‑world elevation data and includes a global roster of airports, from Taipei to London. As you earn reputation, more radars unlock, letting you expand coverage and improve safety across the network.
01 / THE GUIDE
Radar Management
You cannot see aircraft beyond the radar range, but you can still issue directions. Deciding whether to keep a plane identified on radar or rely on a mental picture affects safety and efficiency.
Higher reputation unlocks additional radars, letting you broaden coverage and make flying safer across the map.
- Try keeping critical aircraft on radar when traffic density spikes.
- Use the unlocked radars to broaden coverage and make flying safer.
02 / THE GUIDE
Wind and Runway Management
Aircraft always land and take off into the wind unless it is unsafe. Wind direction and speed change constantly, limiting which runways can be used.
You can adjust runway procedures, including initial and missed‑approach headings and altitudes, to match the current wind conditions.
- Monitor the wind forecast before assigning a runway.
- Adjust missed‑approach headings when wind shifts sharply.

03 / THE GUIDE
Terrain Awareness
All maps use real‑world elevation data, so descending too early in mountainous areas can cause a tragedy. Understanding the terrain is essential for safe approaches.
Pay special attention to mountain regions and avoid directing aircraft to descend below the terrain profile.
- Pay attention to the terrain over which an aircraft is flying to gauge safe descent points.
- Give extra altitude clearance when flying over high terrain.
04 / THE GUIDE
Aircraft Types and Performance
Each of the 125 aircraft types has unique takeoff and landing distances, approach speeds, and speed limits. Matching the right plane to a runway is crucial.
When an aircraft runs out of fuel after being held too long, it will fall, so efficient sequencing matters.
- Check an aircraft’s required runway length before assigning it.
- Prioritize fuel‑critical flights to avoid emergency landings.
