US air traffic control systems have passed critical tests for Year 2000 compatibility, the Federal Aviation Administration has confirmed .
The tests took place over the weekend at Denver International Airport, which was chosen because its computer systems could be divided in two and run in parallel
On Saturday night half of the computers in Denver were advanced to just before midnight on 31 December to verify that radar, navigation, and communications systems would work normally at the switch over into the year 2000.
FAA and airline industry officials said that the computers rolled into the year 2000 with no obvious problems. As a safety precaution the remainder of the computers at Denver International were kept running on current time.
The FAA has come under criticism as it was late in starting work on its Y2K project for its air traffic control system. It missed its 31 March deadline with only a 72 per cent Y2K compliance rate. It claims, however, that it is now on target to have all its systems Y2K- ready by 30 June.
Any Y2K problems that the FAA runs into will cause major disruptions for travellers over the millennium, as it has said it will cut the number of aeroplanes rather than risk a mid-air collision if its traffic control system failed due to system crashes.
