Last month's FAA computer overload that delayed hundreds of flights has been addressed, and the agency announced an update will be in place by year's end. Memory upgrades are expected to improve reliability as early as next month, according to a report in The Wall Street Journal, which quoted Hank Krakowski, chief operating officer of the FAA's Air Traffic Organization. The computer that failed was part of the National Airspace Data Interchange Network-the system that sends flight plans from one FAA facility to another for controllers to clear aircraft for departure. He said, "Our exposure to this will be much reduced." The failure at the Georgia FAA facility was the first of its kind, according to Krakowski.
