About the Game
Air Traffic: Greenlight is an air-traffic-control-themed game that challenges your spatial ability.
The goal is to organize and expedite the flow of air traffic and prevent collisions in areas with limited radar coverage.
Wind direction and wind speed constantly change, limiting the runways that can be used to take off and land. So keep an eye on the forecast.
Directing an aircraft to descend too early could lead to a tragedy.
Appreciate the nature of the terrain over which an aircraft is flying, especially in the mountain area.

The goal is to organize and expedite the flow of air traffic and prevent collisions in areas with limited radar coverage.
Radar Contact
You can't see the aircraft beyond the radar range on the screen, but you can direct it. Choose to maintain radar identification for safety or use your mental picture of the traffic for efficiency.Deploy a Radar
Along with the rise in reputation, additional radars will be unlocked. Depldeveloping your radar network, improving radar coverage to make flying safer.Wind Conditions
An aircraft always land and takeoffs into the wind unless it's safe.Wind direction and wind speed constantly change, limiting the runways that can be used to take off and land. So keep an eye on the forecast.
Terrain
All maps are built based on real-world elevation data.Directing an aircraft to descend too early could lead to a tragedy.
Appreciate the nature of the terrain over which an aircraft is flying, especially in the mountain area.
Aircraft Types
A plane's performance depends on its aircraft type. All types have different takeoff and landing distances, approach speeds, and speed limits.Fuel Emergency
If an aircraft has been held in the air too long, it will run out of fuel and fall. When an airport is too busy to handle all flights, diverting some arrivals to other airports can prevent it.Runway Management
You can change the procedure of all runways, including assigning the initial and missed approach heading and altitude.Replay
You can save, watch and share the replay of your game.Navigation

Hello controllers!
This patch addresses some issues caused by the UI adjustments in the last update.
One of the changes in the previous patch was disabling stretch scaling in high resolutions to preserve the original UI element ratios. However, this could result in text appearing too small on certain screens.
As a temporary workaround before the implementation of adjustable UI text size in the next update, a new option called Force Stretch Scaling has been added to the Video Options menu. Enabling it will apply stretch scaling in high resolutions, as it did previously.
Additionally, Borderless Mode has been permanently removed due to persistent technical issues that prevented it from working as expected. The Resolution setting has also been removed, as it was only applicable to Borderless Mode.

Hello controllers!
This patch primarily focuses on performance improvements.
I've received many questions about whether the game is still in development. The answer is yes—I'm fully focused on the next update and have no plans for another game or DLC at the moment.
This update addresses two major performance issues:
The first issue is primarily caused by the replay system. Some underlying design flaws affect replay precision, so I previously added extra data to minimize offsets. However, I underestimated the impact on save file size.
The next major update is expected to provide a solution for these replay issues, but it will take time. As a temporary fix, this patch reduces additional replay data—though offsets will be more likely to happen. Existing save files won’t be affected automatically. However, you can disable the replay feature for a save file to delete all its replay data and stop further recording. Any future saves from a replay-disabled session will permanently have replay disabled.
