I'm flying into ORD on Tuesday and I'm wondering if anyone happens to know the frequencies for the Chicago area (preferrably Chicago APP/DEP and ORD TWR and ARR and DEP ATIS) (don't need the other 1,376 airports in the metro Chicago area). There's a site somewhere out there that I used to use all the time to get this info, but I've forgotten it. I have no Chicago aeronautical charts, either, so I need help. Danke.

I know this sounds stupid but could you explain to me why there are two towers? and why a whole bunch of other freqs, why not just one? what are the other freqs used for?

Sure, not a stupid question at all. The presence of multiple TWR and APP/DEP freqs is b/c it reduces controller workload on aircraft departing in and arriving from a variety of directions on many runways. There aren't really two towers at O'Hare (to my knowledge) (although there are at many other airports), but having two freqs for the twr greatly reduces twr controllers' workload. This was brought about after a runway collision between a USAir 737 and a Skywest Metro on an LAX runway that was caused by a controller's inattention. That inattention was caused b/c the controller was working both the north runways (24R/6L and 24L/6R) and the south runways (25R/7L and 25L/7R). Similar systems of two or more twr and app/dep frequencies are in place all over the country. In example, ATL has 2 freqs for each local control facility (twr, app, and dep), each divided into south and north vector areas. Hope this helps.
