Your main screen is a radar, which features the aircrafts as green dots or little airplanes, moving at a certain speed at a certain height. The game is a full-talkie, featuring pilot's voices and those of the ATCs. Interestingly Tracon doesn't use a sound card for that. The voice acting is done over the PC internal speaker.
The more traffic is in the air, the more hectic your job becomes. You have to set routes for the planes and organize punctual arrivals.
The game is also featuring emergencies, to make your task more difficult. It is possible to connect the game to a Microsoft Flight Simulator installation on another computer.
Tracon was used to train professional ATCs in the early nineties. Then Wesson decided to develop special simulation units for professional users and continue the Tracon series as entertainment.
