Control real airspace traffic with ATC commands or JavaScript
radarcontrol.io is an air traffic control simulator in the browser. You guide aircraft through real airspaces by typing ATC commands, or you write JavaScript that gives the clearances for you. Your script reacts to events, such as a new aircraft appearing or a conflict, and tells planes to climb, descend, change speed, fly direct to a fix or hold.
