One of the most-used runways at Chicago O'Hare will be shortened by more than 3,000 feet to allow construction of a new runway, the FAA said Monday. The shortened runway will force a shift in some international takeoffs, as well as 1% to 2% of incoming aircraft. The FAA also announced a third airport surveillance radar system for O'Hare, allowing more "high and wide" approaches by aircraft using parallel runways. "It gives you more efficiencies, more choices and more ways to blend in traffic," says an FAA spokesman. "And when you're higher, it might help with noise."
