Jan, The computers that run the ATC system are located at enroute centers (23, coast to coast). They act as hosts to all the terminal computers out there (e.g. LAX, O'Hare, Miama, etc, etc). The computers within the terminals (towers) should not be affected by yk2, but host systems might. At individual facility level, information (to the best of my knowledge) is not date-dependent. The system works on a variety of different, mostly older, equipment, but the host computers provide all the interfaces and flight data information. A note, regardless of what happens to flight data and interfaces, the radar systems should continue to operate, though air traffic would slow down due to loss of automated information exchange. In summary, it could slow down considerably, but it will function. John R. |
