Chicago, United States · 41.979°N 87.905°W · elevation 679 ft

Control the traffic at Chicago O'Hare International Airport in radar-sim , a free air traffic control simulator that runs in the browser: as tower you issue take-off and landing clearances on 04L/22R, 04R/22L, 09C/27C, 09L/27R, 09R/27L, 10C/28C, 10L/28R and 10R/28L, as approach you vector and sequence the arrivals onto the ILS.

The airport has 8 runways. The parallels 04L/22R and 04R/22L are far enough apart for independent parallel approaches (ICAO requires 1035 m between the centrelines): aircraft established on both finals are not subject to the radar minima against each other. The parallel runways 09C/27C, 09L/27R, 09R/27L, 10C/28C, 10L/28R and 10R/28L: 09C/27C – 09R/27L (492 m) and 10C/28C – 10L/28R (373 m) lie closer than 760 m and are worked as one runway, arrivals to both ends separated like on a single final; 10C/28C – 10R/28L (943 m) allows segregated operations only (760–1035 m): approaches on one and departures or missed approaches on the other, but no simultaneous approaches; the other combinations are far enough apart (1035 m) for independent parallel approaches. 04L/22R – 09C/27C and 04L/22R – 09R/27L cross each other: a departure on one and an arrival on short final to the other block each other. The runways in use depend on the traffic level and the wind: one (the best headwind among the longest, here 10L/28R with 3,962 m) on low, two on medium, and on high every runway with a headwind component and at most 20 kt crosswind.

Airspace

The simulated control zone is a circle of 5 NM around the field with extensions along the instrument runways, up to 3,000 ft. In approach sessions arrivals check in over an entry fix and are vectored or sent direct to the initial approach fix of the runway in use; in tower sessions a virtual approach controller does this and hands them over established on the ILS inside 10 NM.
