A second radar system is now online at O'Hare Airport. The Federal Aviation Administration says the latest generation airport surveillance radar will provide coverage of planes that will in the future use new runways. It will also serve as a backup to air traffic controllers if the primary equipment radar fails.

These systems cover a 40 mile area surrounding O'Hare.
