Free ATC simulator ​

radarcontrol.io is a free air traffic control simulator that runs in your browser. No download, no account required. Just open the site and start controlling traffic.

What you get ​

• 170+ airspaces with real FAA and ICAO waypoint data - New York Center, London, Tokyo, and everywhere in between
• 300+ tower mode airports with taxiway routing and runway operations
• SID/STAR procedures with published altitude and speed constraints from FAA CIFP data
• Live METAR weather at every airport, live ATIS at major airports
• Two control modes - type ATC commands with autocomplete, or write JavaScript to automate everything
• Scored sessions with leaderboards to compete against other controllers
• Emergency scenarios - engine failure, decompression, medical emergencies

How to play ​

Interactive mode: Type commands like AAL123 descend FL240 or DAL456 heading 270. Autocomplete helps with callsigns, waypoints, and command syntax. Click aircraft on the radar to select them, drag to set headings.

Script mode: Write JavaScript that reacts to events. Your code runs every tick and controls all aircraft automatically:

onSpawn((aircraft) => {
  aircraft.descendVia(); // follow STAR constraints
});

onConflict((pair) => {
  // resolve separation conflicts
  const ac = traffic.byCallsign(pair.a);
  ac.climb(ac.altFt + 2000);
});
