Simulators
Control simulated traffic from the controller's seat.
Pick an aerodrome and take the air traffic controller's seat. On a radar map, arrivals, departures and circuit traffic call you for clearances. Without a landing clearance, aircraft go around.
Speak over push-to-talk radio (up to 10 minutes at a time) or type or record your calls. Pilots sometimes fly a misheard number until you correct them. Anyone working the same aerodrome with you shares your traffic. Simulator ATC is in beta: join the free beta program with one click.
