Endless ATC Lite is a simulation game in which you play the role of the air traffic controller at a busy airport. Your job is to guide airplanes safely toward the runway (using ILS approaches) to get a high score.

Gameplay

Your game starts with you selecting a plane, sending it to a lower altitude (about 2000 feet), guiding it to the blue ILS line at a large distance from the runway, and clearing it for approach.

Then, each plane you lead to the runway will give you more points; the more points, the more planes will enter the airspace. As you’re playing the game, you’ll gain more and more skills. When a plane has landed on the runway, you’ll be able to select another plane and send it to the runway.
