FAA examines failed upgrade

The Federal Aviation Administration will continue testing new software that failed over the Thanksgiving holiday, causing delays of at least 28 flights.

The software, developed for its air traffic controllers, was tested before being installed at the Orlando International Airport tower of early November, officials said. 'It worked fine,' FAA spokeswoman Kathleen Bergen said. But it will not be put back into the control tower computer system in Orlando until sometime after Jan. 1, she said.

The new software was an upgrade to give more screen capacity to controllers monitoring flights and to make it easier to 'hand off' flights to other controllers.

On Sunday afternoon, Nov. 28, FAA resolved some minor glitches. But as the day wore on, 'more data tags dropped off,' Bergen said. Flight numbers and other information about jets landing and taking off disappeared from radar screens. FAA technicians pulled the upgrade and reinstalled the old software the following day, Bergen said.
