sim4D ATC is a role-playing simulation game developed by Shanghai MT Networks Co.Ltd. for the Windows platform. The game offers a realistic air traffic control (ATC) environment with a professional ATC rule core, requiring players to have basic knowledge of air traffic control and a relatively standard Mandarin accent. The game uses ATC speech recognition (ASR) technology, which means players have to speak out each control command to direct the flight operation instead of relying on mouse drag-click.

The game offers voice interaction ability with an AI captain, which simulates VHF channel call scenes, allowing players to participate in the role of apron/tower controller and experience the most real apron/tower control process. The 4D version of the game upgrades the 2D field surveillance mode to the 3D real scene mode, providing a full-freedom first-person tower view, as well as a God mode airport sand table view. The game offers free DLC with some basic pronunciation essentials and updated learning content of the rules in the in-game "follow-up lessons."
